Description

Technical Field

[0001] This utility model belongs to the field of air source heat pump technology, and specifically relates to a heat exchange device for air source heat pumps. Background Technology

[0002] An air source heat pump is an energy-saving device that utilizes the reverse Carnot cycle principle. Driven by a small amount of electricity, it absorbs low-temperature heat energy from the air, raises the temperature through the work of the compressor, and then releases the heat into the room or hot water system. The heat exchanger of the air source heat pump achieves the absorption and release of heat through the phase change of the refrigerant (conversion from liquid to gas), which is the core link in the energy transfer in the heat pump cycle.

[0003] Existing heat exchange devices for air source heat pumps use copper tubes and aluminum fins to form a heat exchange structure. Refrigerant flows inside the copper tubes, and a fan mounted on the frame blows air towards this structure, absorbing heat from the air and transferring it to the refrigerant. However, in actual use, due to the fixed position of the fan, the airflow reaching the heat exchange structure differs depending on whether the airflow is near or far from the fan. This uneven heat absorption by the structure negatively impacts the refrigerant's heat exchange efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a heat exchange device for an air source heat pump, which can rapidly and evenly heat the copper tube and heat-conducting fins during heat exchange, allowing all parts of the copper tube and heat-conducting fins to absorb heat evenly, thereby effectively ensuring the heat exchange effect on the refrigerant.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a heat exchange device for an air source heat pump, including a frame, air boxes on both sides of the frame, a support inside the air box, a second fan mounted on the support via a position adjustment module, the position adjustment module being used to adjust the air blowing position of the second fan, a dustproof net third being provided on the side of the air box away from the frame; a plurality of evenly distributed mounting plates are provided on the lower surface of the frame, each mounting plate having a mounting groove, and a sponge pad being glued and fixed to the lower surface of each mounting plate.

[0006] As a further improvement of this utility model, the position adjustment module includes a slide cylinder set in the middle of the bracket, with symmetrically distributed slide columns slidingly arranged inside the slide cylinder. Each slide column is provided with a mounting bracket at the end away from the slide cylinder, and the second fan is set on both sides of the mounting bracket. Symmetrically distributed support plates are arranged inside the slide cylinder, and an adjusting screw is rotatably arranged on the side of the support plate away from the slide cylinder. The adjusting screw is threadedly connected to the adjacent slide column. A dual-axis motor is arranged in the middle of the slide cylinder, and the output shaft of the dual-axis motor is fixed to the adjusting screw by a coupling.

[0007] As a further improvement of this utility model, a duct is provided on the upper surface of the frame, a second dustproof net is provided at the top of the inside of the duct, a first fan is provided inside the duct, and a first dustproof net is provided at the air outlet opened on the front side of the frame; a control box is provided on the rear side of the frame, and the first fan, the second fan and the dual-shaft motor are all electrically connected to the control box.

[0008] As a further improvement of this utility model, the frame is provided with a plurality of uniformly distributed heat-conducting plates I, and a plurality of uniformly distributed heat-conducting plates II are arranged between the heat-conducting plates I, and copper pipes are arranged between the heat-conducting plates II.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the operation of fan one causes external air to blow into the interior of the frame from above, and the operation of fan two causes external air to blow into the interior of the frame from both sides. The air blown into the frame is blown out from the air outlet on the front side of the frame, which forces the air to flow within the frame, so that the heat exchange structure composed of heat conduction plate one, heat conduction plate two and copper pipe can be heated evenly.

[0011] Secondly, during the operation of the second fan, the output shaft of the dual-shaft motor rotates back and forth. By adjusting the thread relationship between the lead screw and the slide column, the slide column is driven to slide continuously between the slide cylinder, thereby causing the slide column to drive the second fan to move up and down continuously during operation.

[0012] Thirdly, by coordinating the reciprocating movement of fan two on both sides with the downward blowing of fan one above, heat-conducting plate one, heat-conducting plate two, and copper pipe can be heated quickly and evenly during heat exchange, so that heat-conducting plate one, heat-conducting plate two, and copper pipe can absorb heat evenly at all positions, thereby effectively ensuring the heat exchange effect of refrigerant.

[0013] Fourth, the sponge pad on the underside of the mounting plate can cushion the underside of the mounting plate, thus effectively preventing damage caused by excessive tightening of bolts during installation. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, the device includes a frame 101, with air boxes 201 on both sides of the frame 101. Each air box 201 has a support 203 inside. A second fan 207 is mounted on the support 203 via a position adjustment module. The position adjustment module is used to adjust the blowing position of the second fan 207. A third dustproof net 202 is provided on the side of the air box 201 away from the frame 101.

[0022] like Figure 3 , 4As shown, the position adjustment module includes a slide cylinder 204 located in the middle of the bracket 203. Symmetrically distributed slide columns 205 are slidably arranged inside the slide cylinder 204. Each slide column 205 has a mounting bracket 206 at its end away from the slide cylinder 204. A second fan 207 is located on both sides of the mounting bracket 206. Symmetrically distributed support plates 208 are located inside the slide cylinder 204. Adjusting screws 210 are rotatably arranged on the side of each support plate 208 away from the slide cylinder 204. The adjusting screws 210 are threadedly connected to adjacent slide columns 205. A dual-axis motor 209 is located in the middle of the slide cylinder 204. The output shaft of the dual-axis motor 209 is fixed to the adjusting screw 210 via a coupling. A wind duct 103 is located on the upper surface of the frame 101. A second dustproof net 105 is located at the top of the wind duct 103. A first fan 106 is located inside the wind duct 103. A dustproof net 104 is located at the air outlet on the front side of the frame 101.

[0023] like Figure 2 , 4 As shown, the frame 101 has multiple uniformly distributed heat-conducting plates 107 inside, multiple uniformly distributed heat-conducting plates 108 between the heat-conducting plates 107, and copper pipes 109 between the heat-conducting plates 108.

[0024] like Figure 4 As shown, a control box 301 is installed on the rear side of the frame 101, and the first fan 106, the second fan 207 and the dual-shaft motor 209 are all electrically connected to the control box 301.

[0025] In use, the refrigerant flows inside the copper pipe 109, and then the control box 301 controls the operation of fan 106 and fan 207.

[0026] The operation of fan 106 causes external air to be blown from above into the interior of frame 101. The operation of fan 207 causes external air to be blown from both sides into the interior of frame 101, blowing air onto the heat exchange structure composed of heat-conducting plate 107, heat-conducting plate 108, and copper pipe 109 located in the middle of frame 101. This causes the heat in the air to be absorbed and transferred to the refrigerant flowing inside the copper pipe 109. The air blown into frame 101 is blown out from the air outlet on the front side of frame 101, causing the air to flow in a forced manner within frame 101, so that the heat exchange structure composed of heat-conducting plate 107, heat-conducting plate 108, and copper pipe 109 can be heated evenly.

[0027] During the operation of fan 207, the output shaft of dual-shaft motor 209 rotates back and forth, causing the output shaft of dual-shaft motor 209 to drive the adjusting screw 210 connected to it to rotate back and forth. Through the thread relationship between adjusting screw 210 and slide column 205, slide column 205 is driven to slide continuously between slide cylinder 204, thereby causing slide column 205 to drive fan 207 to move up and down continuously during operation. Through the reciprocating movement of fan 207 on both sides and the downward blowing of fan 106 above, heat conduction plate 107, heat conduction plate 208 and copper pipe 109 can be heated quickly and evenly during heat exchange, so that heat conduction plate 107, heat conduction plate 208 and copper pipe 109 absorb heat evenly at all positions, thereby effectively ensuring the heat exchange effect of refrigerant.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower surface of the frame 101 is provided with multiple evenly distributed mounting plates 102, each with a mounting groove, and a sponge pad is glued and fixed to the lower surface of each mounting plate 102. During use, the sponge pad on the lower surface of the mounting plate 102 can cushion the lower surface of the mounting plate 102, thereby effectively preventing damage caused by excessive tightening of bolts during installation.
