Description

Technical Field

[0001] This application relates to the field of heat exchangers, and more particularly to an apparatus for applying thermal adhesive to a heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid, thus achieving heat transfer between materials. Because no chemical reaction occurs during the heat exchange process and the amount of material lost is almost negligible, it is widely used in industries such as petroleum, chemical, food, and pharmaceutical, and is also widely applied in equipment such as air conditioners and water heaters.

[0003] Heat exchangers in equipment such as air conditioners and water heaters mainly consist of parallel, spaced-apart, and sequentially connected guide tubes. During assembly, heat-dissipating adhesive needs to be applied to the guide tubes as a heat transfer medium to improve the heat exchanger's efficiency. Currently, the adhesive is mainly applied by hand using a glue gun. However, this method is difficult to operate, results in poor accuracy and consistency in the adhesive thickness, and often leads to uneven application, negatively impacting the heat exchanger's heat dissipation efficiency. Furthermore, the application process is labor-intensive, inefficient, and results in significant adhesive wastage. Utility Model Content
