[0034] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] The following is the attached Figure 1 To Attachment Fig. 9 , describing the heat pump device of the first embodiment of the utility model.

[0037] Reference Figures 1 to 4 According to some embodiments of the present invention, the heat pump device includes a housing 100, a heat exchanger 200 and a fan 300; wherein the housing 100 is the shell of the entire heat pump device, and in order to inhale external air into the heat pump device, the housing 100 is provided with an air inlet 111 for inhaling external air, and at the same time, in order to discharge the air that has completed heat exchange to the outside of the heat pump device, the housing 100 is also provided with an air outlet 112 for discharging the air after heat exchange; for the convenience of description below, the direction of the air inlet 111 sucking in external air is defined as the first direction X.

[0038] Reference Figures 1 to 4 The heat exchanger 200 is arranged in the box body 100, and is a component for exchanging heat with the external air sucked in by the heat pump equipment. Therefore, the heat exchange body 210 in the heat exchanger 200 includes a plurality of fins (not shown in the drawings) for completing heat exchange, and gaps (not shown in the drawings) are formed between the fins to allow air to pass through the heat exchanger 200.

[0039] In order to allow the outside air sucked into the heat pump equipment to flow through the heat exchanger 200, the heat exchanger 200 divides the interior of the box body 100 into an air inlet chamber 120 and an air outlet chamber 130, wherein the air inlet 111 is arranged on the cavity wall of the box body 100 corresponding to the air inlet chamber 120 to connect the air inlet chamber 120, so that the outside air sucked into the heat pump equipment through the air inlet 111 can enter the air inlet chamber 120 accordingly.

[0040] The fan 300 is disposed in the air outlet cavity 130 , and the air outlet 112 is disposed on the cavity wall of the box body 100 corresponding to the air outlet cavity 130 , and the air outlet 112 is connected to the exhaust port 340 of the fan 300 .

[0041] In order to improve the compactness of the structure, the fan 300 is arranged adjacent to the heat exchanger 200, and in order to better guide the air flowing through the heat exchanger 200 to the fan 300, an air guide plate 350 is provided on the side of the fan 300 close to the heat exchanger 200, and the air suction port 351 of the fan 300 is provided on the air guide plate 350, and a static pressure chamber 600 is enclosed and formed between the air guide plate 350 and the heat exchanger 200, so that the negative pressure generated by the fan 300 when working can act on the heat exchanger 200 through the static pressure chamber 600; similarly, for the convenience of description below, the air intake direction of the air suction port 351 is defined as the second direction Y.

[0042] At the same time, the heat exchanger 200 is tilted relative to the second direction Y to increase the distance between the air inlet 351 and the fins in the heat exchanger 200 , thereby preventing the air flow rate passing through the fins near the air inlet 351 from being too fast.

[0043] In order to improve the uniformity of the air volume passing through each position on the heat exchanger 200, the inclination direction of the heat exchanger 200 is set so that the distance between the heat exchanger 200 and the air guide plate 350 gradually increases in the first direction X, that is, the longitudinal section of the static pressure chamber 600 parallel to the second direction Y and the first direction X is triangular or trapezoidal.

[0044] It should be understood that by adopting the heat pump device of this embodiment, when the fan 300 is working, the outside air can enter the fan 300 through the air inlet 111, the air inlet chamber 120, the heat exchanger 200, the static pressure chamber 600 and the air suction port 351 in sequence, and under the action of the fan 300, the air that completes the heat exchange with the heat exchanger 200 is discharged from the box 100 through the air outlet 340 and the air outlet 112, thereby completing the heat exchange with the outside air; and because the heat exchanger 200 is inclined relative to the second direction Y, and the longitudinal section of the static pressure chamber 600 parallel to the second direction Y is triangular or trapezoidal, the distance from the air suction port 351 to the heat exchanger 200 is increased, and the volume of the static pressure chamber 600 is increased, so that the flow rate of air flowing through the fins in the heat exchanger 200 can be reduced, especially the flow rate of air flowing through the fins near the air suction port 351, so that the air can fully contact the fins, thereby improving the heat exchange efficiency and reducing noise.

[0045] Moreover, since the width dimension of the cross section of the static pressure chamber 600 parallel to the second direction Y and the first direction X gradually changes from one end of the inclination direction of the heat exchanger 200 to the other end, the wind resistance from the end of the heat exchanger 200 corresponding to the wider cross section of the static pressure chamber 600 (that is, the end relatively far away from the air inlet 111) to the air intake port 351 is relatively small, and the wind resistance from the end of the heat exchanger 200 corresponding to the narrower cross section of the static pressure chamber 600 (that is, the end relatively close to the air inlet 111) to the air intake port 351 is relatively small, thereby changing the uniformity of the wind field in the air inlet chamber 120, so that although the end of the heat exchanger 200 relatively far away from the air inlet 111 is farther away from the air inlet 111, it can still have a similar or close air volume as the end relatively close to the air inlet 111, thereby allowing air to flow through the heat exchanger 200 more evenly to improve the heat exchange effect.

[0046] At the same time, it should be understood that the slanted arrangement of the heat exchanger 200 can further increase the area of ​​the heat exchanger 200, thereby accommodating a larger number of heat exchange tubes, which is also beneficial to further improve the heat exchange efficiency.

[0047] It can be understood that in one embodiment, the angle between the heat exchanger 200 and the second direction Y is 75°, that is, the angle between the heat exchanger 200 and the air guide plate 350 is 15°; and it should be understood that in some other embodiments, the heat exchanger 200 can be tilted at a greater angle based on the actual scene of the box.

[0048] It can be understood that in order to reduce the wind resistance of external air entering the heat pump equipment, in some embodiments, the box body 100 is provided with an air guide ring 113, and the air guide ring 113 is arranged at the position of the box body 100 corresponding to the air inlet 111, and the air guide ring 113 is provided with an annular air guide structure 114, so as to smoothly guide the external air into the air inlet chamber 120 through the air guide structure 114.

[0049] For example, in one embodiment, referring to Figure 4 and Figure 5 The cross-section of the air guide structure 114 is a continuous fillet, and in the air inlet direction of the air inlet 111, that is, in the first direction X, the continuous fillet spans from the air inlet side of the air guide ring 113 to the air outlet side of the air guide ring 113; there is an obvious separation phenomenon when the relative airflow passes through the surface of the right-angle structure, and the airflow will flow along the fillet surface when flowing through the fillet structure, thereby reducing wind resistance, increasing air volume and reducing noise, and the air guide structure 114 with a continuous fillet cross-section can guide the air on both the air inlet side and the air outlet side of the air inlet 111, thereby further reducing wind resistance and noise.

[0050] It is understandable that in order to prevent the air guide ring 113 from protruding from the surface of the box body 100 and affecting the aesthetics, Figure 4 and Figure 5 In one embodiment, the air guide ring 113 is disposed on the inner side of the box body 100. It should be understood that in other embodiments, the air guide ring 113 may be disposed on the outer side of the box body 100, and the air guide ring 113 is used as an interface for connecting the air inlet duct, so as to facilitate guiding the outside air in the outdoor environment to the air inlet 111 through the air inlet duct.

[0051] It can be understood that, for heat pump equipment used indoors, in order to facilitate connecting the outdoor environment and the air inlet 111 and the outdoor environment and the air outlet 112 respectively through the air inlet duct and the air outlet duct, in some embodiments, the air inlet 111 and the air outlet 112 are arranged on the same side wall of the box body 100, and in order to allow the outside air entering the box body 100 through the air inlet 111 to be discharged to the outside of the box body 100 in the opposite direction, the fan 300 is a centrifugal fan 300, that is, the air intake 351 of the fan 300 corresponds to the middle part of the wind wheel 310 in the fan 300, and the air outlet 340 of the fan 300 is correspondingly arranged on the peripheral side of the wind wheel 310, and the second direction Y is perpendicular to the first direction X.

[0052] For example, in one embodiment, referring to Figure 4 , the air inlet 111 and the air outlet 112 are both selected to be arranged on the top plate 110 (i.e., the top box wall) of the box body 100, so that a pipe connecting the air inlet 111 and the air outlet 112 can be arranged from above the box body 100, so that the air inlet 111 and the air outlet 112 can be connected to the outdoor environment; and the fan 300 is installed in the box body 100 in the form of a horizontal arrangement of the wind wheel 310 shaft, and the wind wheel 310 shaft is parallel to the left and right direction, and the air suction port 351 is arranged on the right side of the shell of the fan 300, and is located at a position directly opposite to the center of the wind wheel 310, so that air can be sucked into the fan 300 by the air suction port 351 along the front and rear direction, and the heat exchanger 200 is arranged in the box body 100 at an angle in the left and right direction, and It is located on the right side of the fan 300, and the upper end of the heat exchanger 200 is arranged to be closer to the fan 300 relative to the lower end, so that the cross-section of the static pressure chamber 600 on the vertical plane parallel to the left and right directions is roughly trapezoidal, and in the direction from top to bottom, the width dimension of the cross-section of the static pressure chamber 600 will gradually increase, so that the wind resistance of air being sucked into the air intake port 351 from the lower end of the static pressure chamber 600 is smaller than the wind resistance of air being sucked into the air intake port 351 from the upper end of the static pressure chamber 600, thereby making the lower end of the heat exchanger 200 farther from the air inlet 111 than the upper end, but there can still be similar or close air volume flowing through the lower end of the heat exchanger 200 as the upper end, so that the air can flow through the heat exchanger 200 more evenly to improve the heat exchange effect.

[0053] It should be understood that, in addition to being optionally arranged on the top plate 110 of the box body 100, in some other embodiments, the air inlet 111 and the air outlet 112 may also be arranged on other walls of the box body 100, for example, on the bottom plate 140 of the box body 100 or on the left or right plate of the box body 100.

[0054] It is understandable that in order to enclose and form a static pressure chamber 600 between the heat exchanger 200 and the air guide plate 350, in some embodiments, reference is made to Figure 6 The edge of the air guide plate 350 is provided with a flange, and the flange is bent relative to the air guide plate 350 toward the heat exchanger 200, so that the air guide plate 350 and the flange form a bucket-shaped structure with an opening toward the heat exchanger 200, and the end of the flange away from the air guide plate 350 abuts against the heat exchanger 200, that is, the heat exchanger 200 is located at the opening of the bucket-shaped structure, so that the heat exchanger 200, the air guide plate 350 and the flange together enclose a static pressure chamber 600.

[0055] It should be understood that in order to cooperate with the air guide plate 350 and the heat exchanger 200 to form the static pressure chamber 600, in addition to the above-mentioned flanging method, in other embodiments, it is also possible to choose to use the box walls on both sides of the box body 100 corresponding to the air guide plate 350 and the heat exchanger 200 to cooperate with the air guide plate 350 and the heat exchanger 200 to form the static pressure chamber 600; or, a sheet metal installation part is set inside the box body 100 to cooperate with the air guide plate 350 and the heat exchanger 200 to form the static pressure chamber 600 through the sheet metal part.

[0056] It is understandable that, referring to Figure 7 The heat exchanger 200 includes a heat exchange body 210 and two side plates 220, wherein the heat exchange body 210 includes a plurality of heat exchange units composed of heat exchange tubes and fins, and the two side plates 220 are respectively connected to both ends of the heat exchange body 210 in the width direction to integrate and fix each heat exchange unit.

[0057] At the same time, in order to facilitate the installation and fixing of the heat exchanger 200 on the fan 300, in one embodiment, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 The flanges include a first flange 360 ​​and a second flange 370 respectively opposite to the two side panels 220 , and the first flange 360 ​​and the second flange 370 are respectively fitted with the two side panels 220 .

[0058] In addition, a plurality of first connection holes 371 are provided on the first flange 360 ​​and the second flange 370, and the plurality of first connection holes 371 are arranged at intervals along the length direction of the first flange 360 ​​or the second flange 370, and a plurality of second connection holes 222 are provided on the two side plates 220, and the plurality of second connection holes 222 are arranged at intervals along the length direction of the side plates 220, and the positions of the second connection holes 222 correspond one-to-one to the positions of the first connection holes 371, so that the two side plates 220 can be connected and fixed to the first flange 360 ​​or the second flange 370 by fasteners penetrated through the first connection holes 371 and the second connection holes 222, thereby realizing the fixation of the heat exchanger 200.

[0059] Furthermore, in order to quickly complete the installation pre-positioning of the heat exchanger 200 during the installation process of the heat exchanger 200, in one embodiment, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 The flange includes a third flange 380 and a fourth flange 390, and the third flange 380 and the fourth flange 390 are correspondingly abutted against the two ends of the heat exchanger 200 in the inclined direction, and the third flange 380 and the fourth flange 390 are provided with a snap-in groove 391 at a position corresponding to the side plate 220, and the side plate 220 protrudes from the heat exchange body 210 toward the fan 300, and forms a snap-in portion 221 for engaging with the snap-in groove 391, so as to limit the movement of the heat exchanger 200 except the length direction of the side plate 220 through the cooperation between the snap-in portion 221 and the snap-in groove 391.

[0060] At the same time, refer to Figure 8 In order to prevent the second connection hole 222 from being misaligned with the first connection hole 371 in the length direction of the side plate 220 after the heat exchanger 200 is engaged with the fan 300 through the engagement of the engagement portion 221 and the engagement groove 391, a limiting portion 223 is provided at one end of the engagement portion 221 close to the third flange 380, and the limiting portion 223 is bent relative to the engagement portion 221 toward the heat exchange body 210, so that the limiting portion 223 can abut against the third flange 380, thereby limiting the displacement of the heat exchanger 200 in the length direction of the side plate 220. Movement; thus, during installation, the heat exchanger 200 can be firstly connected to the corresponding clamping groove 391 through the clamping portion 221, and then the heat exchanger 200 can be slid along the length direction of the side plate 220, so that the limiting portion 223 abuts against the third flange 380. At this time, the pre-positioning of the heat exchanger 200 can be completed, that is, the second connecting holes 222 on the heat exchanger 200 can be aligned one by one with the first connecting holes 371 on the fan 300, so as to facilitate the subsequent connection between the heat exchanger 200 and the fan 300 through fasteners.

[0061] It is understandable that, in order to achieve the fixation of the heat exchanger 200 in the box body 100, in some embodiments, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 7 A connecting portion 224 is provided at one end of the side plate 220 close to the third flange 380, and the connecting portion 224 is bent relative to the main part of the side plate 220 toward a side away from the heat exchange main body 210, and a third connecting hole 225 is provided on the connecting portion 224, and a fourth connecting hole is provided on the box wall (bottom plate 140) of the box body 100 at a position corresponding to the third connecting hole 225, so that the connecting portion 224 is fixedly connected to the box body 100 by fasteners penetrating the third connecting hole 225 and the fourth connecting hole.

[0062] It should be understood that in some embodiments, the heat pump device further includes an electric control box 400, which is disposed inside the box body 100, and is electrically connected to the electrical components in the box body 100, and the electric control box 400 has a heat dissipation portion 410 protruding from one side of the box body, and the heat dissipation portion 410 is at least partially disposed in the static pressure chamber 600, so as to cool the heat dissipation portion 410 with the help of the air after heat exchange, thereby improving the heat dissipation effect of the electric control box 400; for example, in one embodiment, referring to Figure 1 , Figure 4 and Figure 6 The fan 300 includes a left volute 320, a right volute 330 and a wind wheel 310. The left volute 320 and the right volute 330 are connected and assembled to form the shell of the fan 300, and the air guide plate 350 is located on the side of the right volute 330 away from the left volute 320.
