Detailed ways

The invention will be further described below in conjunction with the drawings and specific embodiments.

Example 1:

A multi-layer fully heat exchange water storage heat exchanger comprising: a body 1 , the body 1 being welded by the first condensation plate 11 , the second condensation plate 12 , the third condensation plate 13 and the fourth condensation plate 14 . The refrigerant working medium input channel 21, the refrigerant working medium output channel 22, the medium water input channel 23 and the medium water output channel 24 are respectively arranged at four corners; the first condensing plate 11 and the second condensing plate 12 are alternately distributed and placed at both ends of the body 1. The third condensing plate 13 and the fourth condensing plate 14 are hollow inside, and constitute a water storage chamber 3, which are staggered and distributed in the middle of the body 1. The direction of the condensing passage on the first condensing plate 11 and the second condensing plate 12 is different, and the third Condensation channels are arranged around the condensation plate 13 and the fourth condensation plate 14, and the direction of the condensation channels is different; the lower portion of the body 1 is provided with a water outlet 4, and the water outlet 4 is electrically connected to the water storage chamber 3.

The water outlet 4 is a lateral condensation water outlet pipe 41 which is horizontally arranged, or the water outlet 4 is a vertical condensation water outlet pipe 42 which is vertically arranged. The condensing passages of the first condensing plate 11 and the second condensing plate 12 are in opposite directions. The refrigerant working medium input passage 21 is located below the body 1, and the refrigerant working medium output passage 22 is located above the body 1. The medium water input passage 23 is located below the body 1, and the medium water output passage 24 is located above the body 1, and the fold lines of the condensation passages on the third condensation plate 13 and the fourth condensation plate 14 are opposite in direction.

The medium water input channel 23 and the medium water output channel 24 are respectively communicated with the water storage chamber 3 through the conduction cavity, and the conduction cavity is respectively at an angle with the lateral direction and the longitudinal direction of the body 1, and the third condensation plate 13 or the fourth condensation plate is not blocked. Condensation channel within 14. The outer part of the body 1 is provided with a protective end plate, and the end plate is Body 1 package.

After the hollowed-out third condensing plate 13 and the fourth condensing plate 14 are stacked, a water storage chamber 3 is formed, and the periphery of the water storage chamber 3 is also a heat exchange area, which can perform good medium water stored in the chamber. Keep warm. The entire body 1 is stacked, and when soldered, the thickness is uniform and it is easy to be welded.

Since the medium water output passage 24 and the medium water return passage are continuous; this causes a part of the medium water to flow back to the water storage chamber 3 through the first condensation plate 11 and the second condensation plate 12 when the client is recycled, directly It is directly output to the client by the medium water output channel 24. It is necessary to open the nozzle 4 on the lower side of the water chamber 3 formed by the third condensing plate 13 and the fourth condensing plate 14.

Because of the design of the vertical condensation water outlet pipe 42; below the third condensation plate 13 and the fourth condensation plate 14, there is also a heat exchange area between the refrigerant and the medium water, and the vertical condensation water outlet pipe 42 passes through the area. It is necessary to specially design the lower side plate type of the water storage chamber 3 to allow the space of the vertical discharge water pipe 42 to be condensed. If the vertical condensing water outlet pipe 42 is cylindrical, the shape of the notch on the lower side of the water storage chamber 3 is also respectively provided with different opening sizes; the vertical condensing water outlet pipe 42 is cylindrical, and the notch shape of the lower side of the water storage chamber 3 The opening size can be substantially the same. However, the vertical condensing water outlet pipe 42 is welded into the area, and at the same time, it is necessary to ensure the sealing performance of the water storage space and the heat exchanger plate groove, and the production requirements are very high. A separate water outlet is provided on the lower side of the water storage chamber 3 for direct connection with the internal water storage space.

The heat exchanger and the water storage tank are independently arranged, and the connection needs to be installed. The use of pipes, joints, etc. is troublesome, the installation cost is high, and the joints and pipelines are at risk of leakage; the two are separately installed, and the space needs to be separately occupied and arranged separately. The appearance is poor.

The accumulator combines the condenser and the accumulator, eliminating the need for many joints for connection, making it compact and with minimal leakage. At the same time, it increases the efficiency of heating and reduces the space occupied. The plate heat exchanger and the water storage tank are combined into one, the integration degree is higher, the connection pipeline and the joint between the two are omitted, the installation cost is saved, the leakage risk is reduced, the integration degree is higher, and the space is occupied. Small and more beautiful.

The plate heat exchanger is directly integrated into a water storage tank and directly connected through the passage holes; a plate type of a hollow plate heat exchanger is designed, and the plate type is superposed to form a water storage structure inside and hollow around. It is still a heat exchange space; the intermediate water tank is insulated to prevent heat from being emitted to the outside.
