HEAT EXCHANGER, A FOOD HANDLER INCLUDING THE HEAT EXCHANGER, AND A MANUFACTURING METHOD OF THE HEAT EXCHANGER

摘要

Provided are a heat exchanger, a food handler including the heat exchanger, and a manufacturing method of the heat exchanger. Disclosed is the heat exchanger wherein a plurality of flow channels is formed in the inside and thermal transfer is performed between multiple flowing fluids having different temperatures. The heat exchanger comprises a main body wherein the plurality of flow channels passes through the inside of the heat exchanger in a first direction and a pair of cover members which is fastened to both ends of the main body in the first direction. The plurality of flow channels is composed of a first flow channel which functions as the path of a first flowing fluid which goes in and out through the cover members and a second flow channel which is connected to the side of the main body. Thermal exchange is performed between the first flowing fluid and the second flowing fluid in the direction wherein the first and second flowing fluids cross to each other in the inside of the main body.
