Full aluminum automobile radiator composition requirements and heat exchange

- Feb 06, 2018-

Full aluminum automobile radiator in the production process is mainly by the water chamber, water chamber and the radiator core three parts, all aluminum radiator car coolant flow in the radiator, the air outside the radiator As a result, the hot coolant gets chilled as it dissipates heat to the air, and the cool air heats up as it absorbs the heat dissipated by the coolant.

The development of full aluminum automobile radiator materials and manufacturing technology is fast, and its products have a distinct advantage in lightweighting materials. Aluminum radiator occupies an average of 64% of new European cars. The automobile radiator is an indispensable and important component in the cooling system of automobile water-cooled engine. It is moving in the direction of lightness, high efficiency and economy. Car radiator structure is also constantly adapt to the new development.

Full aluminum automobile radiator core in the production process is mainly composed of many fine cooling tubes and fins, cooling tubes are mostly flat circular cross-section, in order to reduce air resistance, increase heat transfer area. The entire core of the unit has sufficient flow area to allow coolant to pass through, while also providing sufficient air flow area to allow sufficient air to pass to remove heat from the coolant to the radiator.

Full aluminum automobile radiator must also have enough heat dissipation area to complete the heat exchange between coolant, air and heat sink. The heat sink should not come into contact with any acid, alkali or other corrosive nature. Aluminum radiator full of water within the car and then re-injection, the first engine cylinder to turn the water switch, water out, and then closed, so as to avoid blisters.
