Cast aluminum composite metal heat exchange device and manufacturing method thereof

Abstract

The invention discloses a cast aluminum composite metal heat exchange device and relates to the field of heat exchange devices. The cast aluminum composite metal heat exchange device comprises heat conducting pipes and a frame connected with the heat conducting pipes. The frame comprises an outer frame body and cooling fins fixedly connected with the outer frame body. The two sides of each cooling fin are connected with the walls of the corresponding adjacent heat conducting pipes. The cooling fins are arranged on the outer frame body and directly make contact with the outer frame body. The outer frame body can transmit and conduct heat for the cooling fins, so that the heat conducting area is enlarged, and the heat exchange effect is more excellent. The two sides of each cooling fin are connected with the walls of the corresponding adjacent heat conducting pipes, the same cooling fin can enlarge the heat exchange areas of the corresponding two adjacent heat conducting pipes at the same time, and thus the overall size of a heat exchanger is reduced. In use, multiple cast aluminum composite metal heat exchange devices are assembled side by side to form the heat exchanger, a continuous wavy surface is formed by the cooling fins and heat exchange pipes so that turbulent flow or eddies can be formed repeatedly when heat exchange media flow through the heat exchange pipes, and accordingly the surfaces of the heat exchange pipes and the surfaces of the cooling fins are not prone to scaling.

Description

technical field [0001] The invention relates to the field of heat exchange devices, and more specifically, to a cast aluminum composite metal heat exchange device and a manufacturing method thereof. Background technique [0002] In the production of oil refining, chemical industry, etc., most of the processes have heating, cooling and condensation processes, which are collectively called heat transfer processes. The heat exchange process requires certain equipment to complete, and these devices that enable the heat exchange process to be realized are called heat exchangers. [0003] The heat exchangers used in the traditional evaporative cooling technology field are made of metal plate tubes and round tubes, and there are many unfavorable factors such as corrosion, scaling, cracking, low heat transfer efficiency, large volume, and weight overload. Especially driven by the semiconductor industry and MEMS, people have developed large-scale and ultra-large-scale integrated cir...

Problems solved by technology

However, this structure stacks many thin plates with micro-channels. Although the heat transfer area is increased, the densely arranged thin plates make it difficult to discharge hot air, poor heat exchange effect, and easy to foul and difficult to clean. The manufacturing process of the heater is relatively complicated, which is not conducive to mass production
