Box-shaped stacked heat exchanger with fine flow channels on the through-hole wall of the pad

By designing a small runner on the through-hole wall of the pad plate, the refrigerant is evenly distributed in the box-shaped stacked heat exchanger, the problem of low heat exchange efficiency caused by uneven refrigerant distribution is solved, and more efficient heat exchange effect and cost reduction is achieved.

AI Technical Summary

Technical Problem

In the refrigerant evaporator, the refrigerant cannot be evenly distributed, resulting in low heat exchange efficiency of the rear heat exchange device and reduced overall heat exchange efficiency.

Method used

A small runner is designed on the wall of the pad through hole so that after entering the heat exchanger, the refrigerant is evenly distributed to each heat exchange device level through these runners, ensuring that the refrigerant undergoes equal heat exchange at all levels.

Benefits of technology

Through the design of the small runner, the refrigerant can be evenly distributed into all heat exchange devices, improving the overall heat exchange efficiency, reducing the number of heat exchange plates and runners, and reducing product costs.

Abstract

The box-shaped stacked heat exchanger with fine flow channels on the through-hole wall of the pad is composed of a plurality of box-shaped heat exchange plates with inclined surfaces on the periphery stacked in sequence. In the box-shaped stacked heat exchanger, on each heat exchange plate, there is a heat exchange device for inter-wall heat exchange, and there are through holes for heat exchange medium to flow. The through holes are distributed at both ends of each heat exchange plate. There are pads on the through holes at both ends of the heat exchange plate and on the extended plane around the through holes. The pads have a certain thickness and there are through holes for heat exchange medium to flow on the pads. The heat exchange device is located in the middle of each heat exchange plate and contacts the pads located at both ends of the heat exchange plate. The characteristic is that there are fine flow channels communicating with the heat exchange device on the through-hole wall of the pad.
