Description

Technical Field

[0001] The utility model relates to the technical field of internal heat exchangers, in particular to an internal heat exchanger component of a water source heat pump air conditioning system. Background Art

[0002] The plate heat exchanger in the water source heat pump air conditioning system is an important component used to exchange heat in the system. The water source heat pump system uses shallow underground geothermal resources (such as groundwater, soil or surface water, etc.) as a heat source or cold source, and realizes heat exchange with the air conditioning system inside the building through a plate heat exchanger;

[0003] After checking the publication number: CN220853243U, a fully welded plate heat exchanger is disclosed. This technology discloses "a fully welded plate heat exchanger. The frame of the heat exchanger is composed of a fixed clamping plate, a movable clamping plate, an upper guide rod, a lower guide rod, and a support. The fully welded plate group is arranged between the fixed clamping plate and the movable clamping plate and fixed by a clamping bolt pair. The fully welded plate group is composed of a plurality of plate welding units and connecting plates between the plate welding units. The plate welding unit is composed of a plurality of heat exchange plates laser welded together. The periphery of the corner hole of the connecting plate is laser welded to the periphery of the corner hole of the adjacent heat exchange plate." and other technical solutions, with "the cold and hot media flow completely in countercurrent in the adjacent plate channels, and heat exchange is achieved through the plates. The design of the corrugated heat exchange plate can cause the medium to produce strong turbulence, greatly improving the conduction capacity per unit area" and other technical effects;

[0004] The fully welded plate group in the above scheme is composed of multiple plate welding units, which can be easily replaced. However, the conventional plate heat exchanger is fixed to the equipment by angle irons, and then the plate heat exchanger is fixed to the angle irons with bolts or rivets; resulting in relatively cumbersome disassembly and installation processes. When the plate heat exchanger needs to be cleaned or repaired, multiple bolts may need to be removed, increasing the complexity and time cost of the operation; and once water seepage occurs in the pipeline, the bolts are prone to rust, further increasing the difficulty of maintenance and replacement.
