[0021] The heat exchanger 1 includes a bracket 6, a fixed splint 7, a movable splint 8 and two guide rods 9. The two fixed splints 7, the movable splint 8 and the bracket 6 are arranged in parallel in sequence. The two guide rods 9 are fixedly mounted on the upper and lower sides of the fixed splint 7 and the bracket 6 through the mounting seats at both ends. The bracket 6 and the fixed splint 7 act as a base.

[0022] The sides of the fixed clamping plate 7 and the movable clamping plate 8 are provided with a plurality of fixing holes that cooperate with the locking bolts 10. The fixing clamping plate 7 is tightly pressed against the heat exchange plate 17 by the locking bolts 10, so that the adjacent heat exchange plates 17 are sealed.

[0023] The fixing clamping plate 7 is provided with four first water pipe holes 11 which are parallel to each other and are used for introducing and exporting hot and cold water.

[0024] The wave structure includes a plurality of wave-shaped heat exchange plates 17 and two reinforcing blocks. The plurality of heat exchange plates 17 are stacked in sequence and arranged between the fixed clamping plate 7 and the movable clamping plate 8. The wave shape can increase the contact area between hot and cold water, thereby improving the heat exchange capacity of the heat exchanger 1 without changing the volume of the heat exchanger 1, thereby directly improving the heat exchange capacity of the entire system.

[0025] The two clamping blocks 15 are respectively sealed and welded on the opposite surfaces of the fixed clamping plate 7 and the movable clamping plate 8. The heat exchange plate 17 cooperates with the clamping blocks 15 so that the heat exchange plate 17 fits tightly.

[0026] The clamping block 15 located on the side of the fixed clamping plate 7 is provided with a third water pipe hole 16 .

[0027] The heat exchange plate 17 is provided with positioning grooves on the upper and lower sides that match the upper and lower guide rods 9. The positioning grooves are used for positioning and installing the heat exchange plate 17 so that the first water pipe hole 11, the second water pipe hole 12 and the third water pipe hole 16 are accurately positioned.

The sealing strips 13 on the two adjacent heat exchange plates 17 have the same orientation, and the directions of the water-guiding patterns 14 are opposite. During heat exchange, the cold and hot water use different flow directions, which can increase the heat exchange efficiency.

[0032] The hot and cold water flows in the pipe formed by the two second water pipe holes 12 on the same side are of the same type and in opposite directions.

[0033] When installing the heat exchanger 1, first install the upper and lower guide rods 9, then position it through the upper and lower guide rods 9, install the head plate on the fixed clamping plate 7, then install several intermediate plates at intervals, and finally install the tail plate, so that the adjacent intermediate plates and the last intermediate plate are opposite to the water guide lines 14 on the tail plate, and finally clamp several heat exchange plates 17 between the movable clamping plate 8 and the fixed clamping plate 7 through the locking bolts 10.

[0034] Compared with the existing technology, the utility model is an independent water-fluorine system for ground source heat pump air conditioning. The heat exchanger in the system adopts a wavy structure, which can improve the heat exchange capacity of the heat exchanger without changing the volume of the heat exchanger, thereby directly improving the heat exchange capacity of the entire system.
