The replacement chamber is divided into multiple replacement spaces by a vertical partition. Each space is equipped with multiple heat conducting pipes. Both ends of the heat conducting pipe are in communication with the refrigerant gas chamber and the liquid chamber respectively. Cold water is introduced into the replacement chamber through the introduction channel and heat exchanged with the refrigerant in the heat conducting pipe.

Technical Field
[0001] The utility model relates to the technical field of water chillers, in particular to a heat replacement device for a water chiller. Background Art
[0002] A chiller is a cooling water device that can provide constant temperature, constant flow and constant pressure. It is mainly used in industrial temperature control, explosion-proof, laser and other fields. In the refrigeration industry, chillers are mainly divided into air-cooled chillers and water-cooled chillers. The evaporator of the chiller is a heat exchange device that relies on the evaporation of the refrigerant liquid to absorb the heat of the cooled medium. The function of the evaporator in the refrigeration system is to absorb heat (or output cooling capacity). In order to ensure that the evaporation process can be carried out stably and persistently, the evaporated gas must be continuously pumped away by the refrigeration compressor to maintain a certain evaporation pressure.
[0003] The current evaporator uses water temperature to make the refrigerant absorb heat and evaporate, but the water temperature will drop rapidly, and the water cannot be replaced quickly, resulting in insufficient heat exchange. For this reason, we propose a heat exchange device for a chiller. Utility Model Content
