Electric vehicle radiator, the working principle of radiator

New energy vehicles are very popular recently. The electric vehicle radiator has also begun to gradually become popular, which is mainly used in the heating and cooling system of electric vehicles, in the heat dissipation module, the electric vehicle radiator plays an important role, mainly used to dissipate heat for electric vehicles. Next, the electric State Xiaobian will introduce you to the electric vehicle radiator!

Electric vehicle radiator, the working principle of radiator - heat dissipation method

The hot water from the engine jacket, from top to bottom or laterally, is divided into many small strands and dissipates its heat to the surrounding air. Increase the heat dissipation area and accelerate the cooling of water. After the cooling water passes through the radiator, its temperature can be reduced by 10 ~ 15℃. In order to take away the heat from the radiator as soon as possible, a fan is installed behind the radiator to work with the radiator. The cooling strength of the forced water cooling system is generally affected by the speed of the engine, the speed of the crankshaft, the pump and the fan, and the external temperature. When the use conditions change, such as the outside temperature is high, the engine is working at low speed and large load, and the cooling intensity is required to be strong, otherwise the engine is easy to overheat.
Electric vehicle radiator, the working principle of radiator - principle introduction

According to the research found that the current electric vehicle radiator is generally made of aluminum alloy material, the water pipe and the heat sink are made of aluminum, the aluminum water pipe is made of flat shape, the heat sink is corrugated, pay attention to the heat dissipation performance, the installation direction is perpendicular to the direction of the air flow, and the wind resistance should be small and the cooling efficiency should be high. The coolant flows inside the radiator core, and the air passes outside the radiator core. The hot coolant cools because it dissipates heat to the air, and the cold air heats up because it absorbs the heat emitted by the coolant, and achieves heat dissipation through the overall circulation.
Because the electric vehicle radiator is an important part of the automobile water-cooled engine cooling system, and with the development of China's automobile market more and more widely, the electric vehicle radiator has also begun to develop in the direction of lightweight, cost-effective and convenient, at present, China's electric vehicle radiator is mainly divided into DC type and cross-flow type two categories. The structure of the core of the heater has two categories: tubular plate type and tubular belt type. The core of the tubular radiator consists of a number of thin cooling tubes and a cooling fin structure. The cooling tube adopts a flat circular section to reduce air resistance and increase the area of heat transfer.
