Abstract

The invention provides a heat exchanger assembly splicing and sealing method. The method comprises the steps that heat exchanger assemblies are spliced together, and a splicing gap of the heat exchanger assemblies is coated with a hot melt adhesive, wherein the hot melt adhesive contains gas. According to the heat exchanger assembly splicing and sealing method and the heat exchanger, the hot melt adhesive is used for replacing sponge and butyl rubber to be used for sealing the splicing gap of the heat exchanger assemblies, and the quality problems such as warping and disengagement of sponge and butyl rubber materials can be avoided due to the fact that the hot melt adhesive has viscidity. The hot melt adhesive is filled with gas, so that the hot melt adhesive with air holes is formed, the using amount of the hot melt adhesive can be reduced, and the cost can be reduced. In addition, due to the fact that the heat conductivity coefficient of gas is generally small, the energy efficiency of the heat exchanger can be better improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a method for splicing and sealing heat exchanger components and a heat exchanger. Background technique [0002] In the heat exchanger production process, in order to maximize the production and utilization efficiency of the heat exchanger mold, it is not suitable to replace the heat exchanger mold frequently. Generally, one mold corresponds to one heat exchanger component. The heat exchanger components are spliced ​​into one heat exchanger, and this type of heat exchanger is generally called a non-integrated heat exchanger. [0003] There will be gaps of different sizes at the junction of the two heat exchanger components of the non-integrated heat exchanger; in order to ensure that the non-integrated heat exchanger does not leak air when the whole machine is running, and to improve the heat exchange energy efficiency of the heat exchanger, this Technical personnel in the ...
