A Simple Guide On Radiator And Condenser In Car


A car radiator is a heat exchanger that’s that is utilized to bring down the temperature of coolant/antifreeze in the engine. Radiators contain narrow tubes that are intended to scatter heat quickly, helping to maintain the right operating temperature of the engine. Radiators make up the basic part of a vehicle’s cooling system. They’re set at the front of the engine where they’re fed by a progression of air, which assists with the cooling system. Radiators receive a nonstop progression of coolant/antifreeze, which goes through the engine bay to continue moving parts working at the right temperature. Hot coolant/antifreeze goes in and cool coolant/antifreeze comes out; that summarizes what a radiator does. To guarantee that the coolant/antifreeze can go through the radiator at an acceptable speed, it’s forced through by a centrifugal pump – maximising the flow rate of the coolant fluid.

What is an air-conditioning condenser?

The air conditioning system in a vehicle is made of many components. Every part plays its own part and is bound to each another. One significant part of a car air conditioner system is the condenser. The ac condenser acts as a heat exchanger that is utilized to change high-pressure gas to a high-pressure liquid, then gets streamed to the Receiver Dryer until it proceeds to the expansion valve.

Radiators And Condensers – A Simple Guide

Radiators are heat exchanger and it is used to transfer thermal energy. The main purpose of the best radiators is cooling and heating. The radiators are constructed to function in buildings, cars, and electronics. Radiators are the source of heat, although this may be either used for the purpose of heating or for cooling the fluid or coolant supplied, as for automotive engine cooling & HVAC dry cooling towers. Mostly radiators transfer a lot of heat via convection instead of thermal radiation.

Performance of the radiators is essential for proper engine cooling & function. On the other hand, the condenser is a heat exchanger i.e used to condense a gaseous substance into a liquid state through cooling. The latent heat is released by the substance & gets transferred to the surrounding environment. These are used for efficient heat rejection in several industrial systems. It can be made as per the huge number of designs, & come in a lot of sizes ranging from rather small to very large.

Why is the radiators important?

The radiator is a part of the cooling system in the vehicle & has the main purpose of keeping the engine coolant fluid at the proper level. The coolant circulates throughout the engine & also keeps the engine components from overheating. The engine can be get damaged as a result of these extreme temperatures. It may cause significant engine damage i.e caused by overheating – in most of the cars we see the billowing smoke on the side of the road. It is totally caused by malfunctioning radiators! Radiator malfunction is caused by physical damage, that warrants a replacement of one or all of its components.

Why are Condensers important?

These are basically responsible for condensing the enriched vapors at the top, promoting the reflux of liquids to the column, & allowing the withdrawal of distillate. It plays a vital role in this process by essentially dissipating the heat carried to the outdoor unit. The condenser simply allows the cooling process to continue.

Differences Between Car Radiators & Car Condensers

While they both i.e car radiators & car condensers perform similar functions, but there are a variety of differences between car radiators & condensers. A car radiator is a part of the cooling system of engine, while on the other side the condenser is a component of the AC system. The radiator also uses a coolant to conduct heat from the engine & also dissipate it to the environment and the condenser uses pressurized inert gas for heat dissipation. Additionally, the AC system features a fan adjacent to the compressor, increasing the gas’s cooling rate. The condenser is placed in front of the condenser as it requires more airflow for optimal performance.

Electric radiators

Electric radiators are filled with a thermodynamic fluid such as oil, which transfers into heat energy when used with electricity. This means less maintenance is required than water-filled radiators as there is no need to bleed them. Every electric radiator is fitted with a thermostat which controls the amount of power needed to maintain the desired temperature level to heat the home.

Air-cooled condenser 

An air-cooled condenser is a dry cooling system where steam is condensed inside finned tube radiators. This type of condensers is used for thermal power plants such as biomass, concentrated solar, coal, combined cycle & waste to energy. Power plants, which are equipped with ACCs, do not require a large volume of cooling water, the power plants can be built in a region where water may not be available, or where its use is expensive or restricted. Here, are various air-cooled condenser manufacturers in India.
