Technical Field

[0001] This utility model relates to the field of heat exchangers, and more specifically, to a heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, and are widely used.

[0003] Currently, heat exchangers cannot slow down the flow of refrigerant when transporting it through the refrigerant tubes. As a result, the refrigerant flows through the tubes quickly, reducing its working efficiency. Furthermore, existing heat exchangers cannot easily transport refrigerant to multiple tubes simultaneously, causing many inconveniences in refrigerant delivery. Utility Model Content

[0004] The purpose of this invention is to provide a heat exchanger to solve the problems of cooling effect of refrigeration pipe and refrigerant delivery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger, which reduces the flow rate of the refrigerant and prolongs the residence time of the refrigerant inside the refrigerant tube by setting multiple buffer plates inside the refrigerant tube, thereby reducing the cooling effect of the refrigerant and reducing the waste of refrigerant coolness. At the same time, the setting of the left and right dispersers facilitates the refrigerant to flow to each refrigerant tube at the same time, and then the refrigerant inside each refrigerant tube flows to the right disperser and then flows out of the heat exchanger.

[0006] Preferably, the liquid inlet pipe is located inside the left end cover, and the liquid outlet pipe is located inside the right end cover. The liquid inlet pipe allows the refrigerant to flow into the refrigerant pipe, and then the liquid outlet pipe discharges the refrigerant.

[0007] Preferably, the left diffuser is located inside the left end cover, and the right diffuser is located inside the right end cover. The arrangement of the left and right diffusers facilitates the outflow of refrigerant from each refrigeration pipe and allows refrigerant to flow into each refrigeration pipe simultaneously.

[0008] Preferably, the left side of the refrigeration pipe is fixedly connected to the left end cap, and the right side of the refrigeration pipe is fixedly connected to the right end cap. By setting the left and right end caps, the left and right ends of the shell are sealed and plugged respectively.

[0009] Preferably, the left and right ends of the shell are respectively fixedly wrapped with reinforcing rings, and the lower end of the reinforcing rings is fixedly connected to a bracket, so that the heat exchanger is supported and reinforced by the reinforcing rings and the brackets.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) By setting multiple buffer plates inside the refrigeration pipe, the speed of the refrigerant flow is reduced and the time the refrigerant stays inside the refrigeration pipe is extended, thereby reducing the cooling effect of the refrigerant and reducing the waste of the coolness of the refrigerant.

[0012] (2) By setting up the left and right dispersers, this utility model makes it convenient for the refrigerant to flow to each refrigerant tube at the same time, and then the refrigerant inside each refrigerant tube flows to the right disperser and then flows out of the heat exchanger.
