Injection molding heat exchanger device

Abstract

The invention relates to the technical field of heat exchangers, and discloses an injection molding heat exchanger device which is characterized in that a plastic shell integrally formed through an injection molding process is adopted, the plastic shell comprises a groove formed inside, a first baffle plate and a second baffle plate, the first baffle plate and the second baffle plate are arranged on the front inner wall and the rear inner wall of the groove, and a cooling liquid channel is formed between the first baffle plate and the second baffle plate; a cooling liquid outlet is formed in the right side of the rear wall of the plastic shell; a heat exchange core is installed in the groove and comprises end plates at the left end and the right end and a plurality of aluminum fins evenly distributed between the two end plates, and the end plates and the aluminum fins are fixed to the heat exchange copper pipe. A plastic cover plate is installed on the plastic shell, two copper pipe via holes are formed in the plastic cover plate, and a heat flow inlet and a heat flow outlet in the heat exchange copper pipe penetrate through the copper pipe via holes and extend to the position above the plastic cover plate. The invention aims to simplify the production and processing procedures of the heat exchanger, improve the production efficiency, reduce the production difficulty and save the labor cost.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an injection molding heat exchanger device. Background technique [0002] The existing shell-and-tube heat exchanger is basically made by welding the end plates of steel pipes to make the shell, and the heat exchange copper tubes and baffles are passed through the middle to realize indirect heat exchange in the form of swept heat exchange. This structure has the following problems. : First, the steel pipe and the end plate need to be welded and sealed, which is difficult to process, and the production process is many and complicated, and it is easy to have welding defects and affect the quality; Second, the production is labor-intensive and time-consuming, and the high skill level of personnel is required, which directly limits the production capacity. increase, resulting in production bottlenecks. [0003] Therefore, it is necessary to develop a simplified shell heat ex...
