Problems solved by technology

[0004] However, as described in Patent Document 1, when two evaporators are connected in series through piping and two condensers are connected in series through piping, pressure loss due to piping occurs and the power of cooling water and cooling water pumps increases. , so that the power consumption of the pump increases, and there is also the problem that a large installation space is required to increase the length of the refrigerator system.

Abstract

The connecting device for heat exchangers provided by the present invention can connect two heat exchangers by using the connecting device to eliminate the connecting pipes of the heat exchangers, thereby reducing the pressure loss and shortening the dimension of the refrigerator system in the longitudinal direction, thereby enabling Keep the setup space to a minimum. The connection device (2) is used to connect the shell-and-tube heat exchangers of the two passages of two refrigerators, and is provided with: a partition plate (22), which is connected to the main body of the connection device ( 21) is divided inside, thereby forming a flow path, and the connecting device main body (21) is provided with: a first opening (A1), which allows the fluid to pass through one side of the first heat exchanger (1-1) of the two passages The passage of the second heat exchanger (1-2) flows in and out; the second opening (A2) allows fluid to flow in and out of the passage of one side of the second heat exchanger (1-2) of the two passages.

Description

technical field [0001] The present invention relates to a connection device for heat exchangers for connecting shell-and-tube heat exchangers of two passages of two refrigerators. Background technique [0002] Conventionally, a refrigerator system including a plurality of refrigerators including an evaporator, a compressor, a condenser, and the like has been used. In this refrigerator system, for example, as described in Japanese Patent Application Laid-Open No. 2007-183077 (Patent Document 1), two evaporators of two refrigerators are connected in series through piping, and two condensers are connected in series through piping. Therefore, the cold water is sequentially cooled by the evaporation heat of the refrigerant in the two evaporators, and the cooling water sequentially cools the refrigerant vapor in the two condensers. By supplying cold water and cooling water in series to a plurality of refrigerating machines in this way, the average evaporation temperature can be r...
