Flat-tube radiator as air heater with 3D ribs for truck

Abstract

A 3D fin flat-tube radiator as the air heater for truck is composed of a fan, 3D-fin flat-tube radiator, case cap assemblage, case body assemblage, manipulating system and motor. The flat tubes with internal and external fins are welded between two support plates, which are in turn welded to closure heads and sealing plates sequentially. Its advantages are small size and high heating capacity.

Description

technical field [0001] The invention relates to a heating and defrosting air warming device for a cab of a heavy-duty vehicle, in particular to a three-dimensional rib flat tube radiator heating device for a heavy-duty vehicle. Background technique [0002] At present, there are mainly two types of radiator heaters used on heavy-duty vehicles: the tube-fin type and the tube-belt type. According to the introduction of domestic and foreign materials and the driving and use of heavy-duty vehicles in my country's "Three North" regions, it is shown that the tube-fin radiator heaters and tube-belt radiator heaters at home and abroad, when the ambient temperature is -25°C, The temperature of the driver's feet, head and chest area cannot be lower than 15°C. The main reason is that these two heaters have low heat dissipation performance and cannot meet the requirements of heating and defrosting in the cab of a heavy-duty vehicle. Reasons affecting the low hea...

AI Technical Summary

Problems solved by technology

Therefore, the heat dissipation capacity of the first two heaters is low, and the long-term use cannot meet the requirements of heating and defrosting

[0003] At present, the heating devices of tube-fin radiators and tube-belt radiators in China have low heat dissipation capabilities, and the above defects also exist, which affect the driver's working conditions and work efficiency.
