Truck Radiator Importance And How It Prevents Overheating Of Vehicles.

truck radiator

Most people are not aware of the importance of radiators. The Truck radiator is the vital component that is responsible for cooling vehicles. Its function is to monitor the temperature of the vehicle and prevent it from overheating.

Components of Truck Radiator :

1) The core
2) The pressure cap
3) Outlet Inlet tanks
4) Radiator hoses

The core is the important part that allows hot coolant to flow through the engine releasing its heat and the radiator cools it for the next trip around the heat exchange.

The pressure cap ensures the cooling system remains pressurized by sealing it. The coolant is pressurized in the radiator and prevents it from boiling. In this way, it helps the system to become more efficient.

The inlet and outlet tanks are located in the rotator head where the coolant flows in and out of the radiator. The inlet tank allows the hot liquid to flow from the engine and when it is cooled goes out through the outlet tank and then back to the engine.

Radiator hoses help the coolant move through the engine. It is important for connecting the inlet and outlet tanks to the radiator and engine.

The water pump and the thermostat are other important cooling system parts that work alongside your radiator.

The temperature of the engine is regulated by the thermostat. The thermostat will let more coolant in if the engine requires cooling. If the engine is at the right working temperature, then it won’t let off the coolant.

The coolant is forced through the system by the water pump. The engine drive belt typically turns on the pump, which then spins the pump’s blades to push liquid through the system as needed. The coolant is kept inside gaskets and seals.

Coolant is also important as it prevents the engine from overheating. This also helps to lubricate the different parts.

Check the Heavy Truck Radiator if it has an issue

  • Check if the coolant leaks

Sometimes when you park the vehicle and if you notice low coolant levels then there must be a crack in your radiator. This leaking of coolant can be easily seen on the ground.

  • Discolored coolant

The coolant is green and yellow and is thin in consistency. Rust can change the color of the radiator and it becomes dark and rusty in color and becomes thick and consistent. This prevents the engine from cooling.

  • Overheating of Truck Radiator

A vehicle may be heated again and again, the Truck Radiator can be the reason for it since it is the way by which engine heat is removed.

  • Damaged fins

Due to damaged fins, the airflow is blocked to the radiator. The fins are generally damaged due to too much pressure while cleaning them.

Why Air Cooled Condenser Are Best To Remove Excessive Heat

Air Cooled Condenser

Air Cooled Condenser is used in various applications as they are highly efficient. They are high in performance and are widely used in the radiator and automotive condenser coils. The condensers are resistant to corrosion and have better heat transfer. The Air Cooled Condensers meet all the cooling requirements as they have high heat exchanger capacity.

Types of Microchannel (Air Cooled Condenser)

Based on the condensing medium, three different types of Air Cooled Condensers are used to remove heat from the system. This depends on the situation and which condenser is appropriate for the particular situation.

There are three types of Microchannel condensers

  • Water cooled condensers 
  • Air-cooled condensers
  • Evaporative condensers

Water cooled condensers

These condensers are used with compressors of 1hp or more. This condenser is economical as this water is used. In this, the water cools the hot refrigerant and converts it into liquid. These condensers are widely used where there is a continuous supply of water.

There are three types of water-cooled condensers

  • Double tube
  • Shell and coil condenser
  • Shell and tube condenser 

Air Cooled Condenser

A finned continuous tube coil makes up condensers. Vapor from the compressor discharge enters the top of the coil, and liquid exits the bottom, flowing into receivers beneath the base. The condenser coil is blown with air by a fan that is installed on the pulleys of the compressor motor.

The unit must be located in a ventilated and cooled place. If the temperature of ambient air is low then less power is required for the same capacity. Its main advantage is that it is simple and the installation cost is also low. They are mostly used in water coolers, air conditioners, etc. This air is used as the external fluid to reject heat from the system. Moreover, these condensers have copper coils and the refrigerant flows through them. 

The Air Cooled Condensers are of two types.

  • Natural convection
  • Forced convection

Natural convection

When the air comes in contact with the hot coil, it absorbs refrigerant heat inside the coil and increases the temperature. The warm air replaces the cold air as it is lighter in weight and also the cold air touches the hot coils to reject heaters. This process continues till the refrigerant loses heat.

Forced convection

The heat from the refrigerant inside the coil is removed by a fan or blower. The fan blows the air inside the coils. The fins in these condensers are tightly placed. It is mostly used in air conditioners, water coolers, etc.

Evaporative condensers

Air flows upward into the refrigerant coil through spray, eliminator, and fan and is discharged at the top of the unit. Refrigerant enters the top of the coil and flows down 

Coolants enter the coil at the top and flow downward. The receiver, which is frequently housed in the water tank, receives the condensed liquid and uses it to further cool the liquid refrigerant. A pump that is placed on the unit draws water from it and releases it through a spray nozzle that points downward above the refrigerant coil.

The circulating water evaporates and is transferred to the tank through a valve. The salt concentration is increased in water due to evaporation. Due to the increase in salt concentration water treatment is recommended.

Comparison between the three condensers

Evaporative condensers are mostly used in places where the supply of water is less. They are also more cost-effective than water-cooled condensers. When the weather is cold, the evaporator is kept outside and the water pump is turned off to avoid freezing water.

Additionally, the maintenance cost of air-cooled condensers is low in comparison to water-cooled condensers.

Why are Condenser Coil Better Than Traditional Condensers?

condenser coil

Microchannel Condenser Coil is widely used as they provide high performance. They are significantly used in various applications. The traditional heat exchangers are less capable than it. By reducing thermal resistance and system size, there is an increase in the efficiency of the system level. It is widely used in radiators and automotive Condenser Coil.

The coils are made of aluminum and are mostly used because of superior heat transfer due to increased surface area. 

This technique differs significantly from the traditional copper-aluminum condenser and is more than reliable; nearly it’s a standard in the automotive industry. The microchannel condenser is constructed entirely of aluminum, and the fins are put between the two successive tubes and fixed. These fins are procured from a single-channeled aluminum sheet. 

Along the tubes, a variable number of channels can have different geometry. Compared to the tubes utilized in copper-aluminum coils, the internal sections of these channels are incredibly narrow. 

Advantages of Condenser Coil

The condenser coil is generally more efficient than its copper-aluminum counterparts of the same size due to these characteristics, enabling an efficient heat exchange between the condensing fluid and the battery channels. 

The main advantage of a microchannel battery is its low volume which means less refrigerant inside the condenser.

However, conventional condensers are 30% to 50% of the total refrigerant mass of the machine, the microchannel condensers decrease the whole mass of the refrigerant and its respective price. Microchannel condensers greatly enhance the performance of HVAC systems compared to conventional finned tube designs.

  • An increase in heat transmission efficiency drops lower airside pressure

Another important advantage of microchannel heat exchangers over conventional HVAC coil designs is their low airside resistance. The similar size microchannel heat exchanger has a 60 percent less airside pressure drop than a 6-row finned tube heat exchanger of the same size and capacity. Thus, it lowers the fan power consumption and noise level generated by the fans 

  • The coil face area is reduced 

Aluminum microchannel heat exchangers have gained much popularity in the automotive industry due to their lightweight, small size, and low internal volume. These qualities are essential in the cooling systems industry, particularly when it comes to mobile cooling systems. Their reduced size and weight relate not only to the cheaper transport and handling costs but also to the lowered employment cost.

  • Resistant to corrosion

The corrosion potential of the all-aluminum microchannel coils is substantially lower than that of multi-metal coils as there are no dissimilar metals. As a result, microchannel coils are fundamentally a superior option for installations near the ocean, in polluted areas, or in any other situation where corrosion might be a problem. Compared to manually brazed heat exchangers, microchannel coils only need one braze operation in a controlled environment, lowering the possibility of leaks.

  • Protective coating 

The multi-metal finned tube coils are more susceptible to galvanic corrosion than aluminum microchannel coils. So installing multi-metal finned tube coils may require a high level of protection. We advise employing microchannel heat exchangers in petrochemical facilities, adiabatic systems, installations in extremely contaminated areas, or maritime atmospheres to ensure long service life.
