Latest company news about How does a car radiator work?

In today's society, more and more cars have entered the era of new energy, but there are more and more problems with electric vehicles. They are mainly used in the heating and cooling system of electric vehicles. In the thermal module, electric vehicle radiators are mainly used for electric vehicles. Heat dissipation plays an important role. Now, I will introduce the working principle of car radiator to Yuanyang Thermal Factory.

Car heater and its working principle - principle introduction


Through research on the reference materials of small series cars, it is found that most of the radiators of electric vehicles are basically made of aluminum, and the water pipes and radiators are also mostly made of aluminum. The aluminum water pipe is flat and the pins are corrugated, emphasizing the cooling performance, the installation direction is perpendicular to the airflow direction, and the wind resistance is small, so as to maximize the cooling efficiency. Antifreeze flows into the radiator core and air flows out of the radiator core. The hot antifreeze liquid releases heat to the air body and becomes cold, and the cold air body absorbs the heat of the antifreeze radiation to warm up, and releases heat through the whole cycle.


The electric vehicle radiator is an important part of the cooling system of the automobile water-cooled engine. With the development of my country's automobile market, the electric vehicle radiator is also developing in the direction of light weight, cost performance and convenience. At present, the focus of domestic electric vehicle radiators is DC type and cross-flow type. The structure of the heater core can be divided into two types: tube sheet type and wide and thick type. The core of a tubular radiator consists of many micro-cooling pipes and radiators. The cooling duct uses a flat circular section to reduce air resistance and increase the heat transfer area. Introduction to the working principle of the radiator


When you start your car, the heat generated is enough to destroy the car itself. Therefore, install a cooling system on the car to protect the car from damage and keep the engine in a moderate temperature range. The radiator is a critical component of the cooling system, protecting the engine from damage caused by overheating. The principle of the radiator is to reduce the temperature of the engine antifreeze on the radiator by the cold air. The heat sink consists of two main structures. One is a cooling plate consisting of small flat tubes and the other is an overflow tank (top, bottom or sides of the cooling plate).


The role of car radiators in automotive equipment is not necessarily as simple as cooling. Here is a reminder that when cleaning the tank condenser cover with a high-pressure water gun, don't rush into the engine. All cars now use electronic fuel injection systems, so the engine compartment has the engine computer, transmission computer, ignition computer, various sensors and actuators. Flushing with a high pressure water jet may cause a short circuit and damage the engine computer..
