Abstract

In order to further improve the heat exchange efficiency of the compact heat exchanger in the prior art, the present invention provides a fin-type dissimilar metal heat exchanger with high heat exchange efficiency, which includes an outer shell and an inner shell located inside the outer shell. A liquid channel is formed between the outer shell and the inner shell, the inner cavity of the inner shell is a flame channel, and copper or copper alloy inner fins are arranged on the inner surface of the inner shell, and the inner shell Aluminum or aluminum alloy outer fins are arranged on the outer surface of the body. By adopting inner fins and outer fins of different materials, they give full play to their respective advantages, improve the heat exchange efficiency of the heat exchanger, solve the problem of too long warm-up and start-up time of the vehicle engine in low temperature environment, and improve the environmental adaptability of the vehicle , to achieve fast and reliable start-up of the vehicle in a low-temperature environment.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency heat exchange for fuel oil and gas heaters, in particular to a fin-type dissimilar metal heat exchanger for fuel oil and gas heaters. Background technique [0002] Engine low-temperature auxiliary starting equipment (hereinafter referred to as heater) is an important auxiliary device for rapid engine cold start, vehicle interior heating, windshield defrosting and battery insulation under low temperature conditions. It has good application prospects both at home and abroad. The heater is mainly composed of a heat exchanger, a burner and a controller. The performance of the heat exchanger determines the adaptability and reliability of the engine's low-temperature start-up. A heat exchanger with a good heat exchange effect can greatly shorten the time. With the continuous emergence of modern new technology, new technology and new materials and the increasingly severe energy problems, it is o...
