Description

Technical Field

[0001] This utility model relates to the field of heat exchange devices for water-cooled industrial chillers, and more specifically, to a heat exchange device for a water-cooled industrial chiller. Background Technology

[0002] Industrial chiller heat exchangers use refrigerant to absorb heat from the water in the tank, thereby generating cooling water in the tank. This cooling water is then used to cool external equipment. However, in existing technologies, it is difficult to completely drain the water from the tank when the machine is not in use for a long time, which can easily cause the water in the tank to freeze. Moreover, the cooling loss of the water tank is relatively large in existing technologies. In existing technologies, such as the authorized publication number CN205505507U, an industrial chiller heat exchanger includes a water tank, a metal coil, and insulation cotton. The water tank forms a water storage cavity, and the water tank has an outlet and a return outlet communicating with the water storage cavity. The outlet and return outlet are respectively connected to the inlet and outlet of the cooling circuit of external equipment. A drain outlet is provided at the lower end of the side wall of the water storage cavity. The bottom surface of the water storage cavity gradually slopes downwards from the side away from the drain outlet to the side closer to the drain outlet. A rubber plug is provided at the outer end of the drain outlet. A water inlet communicating with the water storage cavity is provided at the upper end of the water tank. A reinforcing rib assembly is also provided at the bottom end of the water tank. The metal coil is wound inside the water storage cavity, with both ends of the metal coil extending above the water tank and forming a refrigerant inlet and a refrigerant outlet, respectively. Insulation cotton is wrapped around the outside of the water tank. This invention allows for convenient drainage of the water tank when the machine is not in use, and minimizes the loss of cooling capacity. In the aforementioned patent, a separate drain pipe is used, which is located on the side of the water tank. However, the drainage is not thorough, and water will remain at the bottom. Furthermore, the separate drain pipe is prone to leakage during use. Utility Model Content
