Square heat exchanger

Abstract

A square heat exchanger comprises a heat exchanger housing, a first flow guide tube box, and a second flow guide tube box, wherein the first flow guide tube box and the second flow guide tube box are fixedly connected with two ends of the heat exchanger housing; the middle part of the first flow guide tube box is communicated with that of the second flow guide tube box through a plurality of heat exchange tubes; a tube pass inlet is formed in the top of the first flow guide tube box, and a tube pass outlet is formed in the bottom of the first flow guide tube box; a shell pass inlet is formed right in the middle at the top of the heat exchanger housing, and a shell pass outlet is formed right in the middle of the bottom of the heat exchanger housing; a flow divider is arranged inside the heat exchanger housing, and comprises a flow dividing box and a plurality of flow dividing tubes arranged on the flow dividing box; one ends of the flow dividing tubes adopt the closed structure, and the other ends of the flow dividing tubes are communicated with the shell pass inlet through the flow dividing box; a plurality of flow diving holes are formed in bottoms of the flow diving box and the flow dividing tubes uniformly; both the flow diving box and the flow dividing tubes are arranged right above the heat exchange tubes. Through the design, the heat efficiency is high, and the application range is wide; therefore, the square heat exchanger is suitable for various narrow arrangement spaces.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a square heat exchanger, which is particularly suitable for improving heat exchange efficiency. Background technique [0002] Heat exchangers are widely used in petrochemical and other fields. Its main function is to ensure that the process helps different media to exchange heat, and it is one of the main equipment to improve energy utilization. For some installation locations with limited space, the use of square heat exchangers can make full use of the layout space and improve heat exchange efficiency. Since the square heat exchanger is suitable for heat exchange of low-pressure medium, its flow pressure is relatively small, how to ensure that the medium can achieve sufficient heat exchange effect has been a subject of constant research by those skilled in the art. [0003] The Chinese patent authorization announcement number is CN201764851U, and the utility model patent whose author...
