On October 28, 2024, the financial sector reported that the China National Intellectual Property Administration information showed that Hubei Youcheng Thermal Equipment Co., Ltd. applied for a patent named "micro tubular heat exchanger with high space utilization", with the publication number of CN 118816593 A and the application date of August 2024.
The patent abstract shows that the present invention relates to the field of heat exchanger technology and proposes a high space utilization micro tube heat exchanger, comprising a shell. The inner side of the shell is provided with a heat exchange component, which includes two partition plates. The two partition plates are fixedly connected at both ends of the inner side of the shell, and there are several heat exchange pipe fittings that pass through the two partition plates fixedly connected between the two partition plates. Several heat exchange pipe fittings are evenly distributed on the partition plates, and material chambers are opened at both ends of the inner side of the shell. The inlet and outlet pipes are respectively connected to the inside of the two material chambers, and a guide piece is provided on the inner side of the shell to increase the flow resistance of the refrigerant. The heat exchange tube of the present invention adopts multiple sets of triangular arrangements, which can increase the flow resistance of the refrigerant, prolong the contact time between the refrigerant and the heat exchange tube, enhance the turbulence of the refrigerant flowing between the tube bundles, effectively increase the disturbance of the refrigerant in the boundary layer of the heat exchange tube, and thus enhance the heat transfer effect.
