Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a heat exchange structure of refrigeration equipment. Background Art

[0002] Heat exchange equipment is a device that transfers heat from hot fluid to cold fluid. Heat exchange equipment is widely used in oil refining, chemical industry, light industry, pharmaceutical industry, machinery, food processing, power and atomic energy industry.

[0003] Existing refrigeration equipment exchanges heat by arranging multiple groups of heat exchangers together.
