DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solutions and advantages of embodiments of the present disclosure clear, technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. However, the described embodiments are merely some but not all embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art on the basis of the embodiments of the present disclosure and falling within the scope of the claims shall be included in the protection scope of the present disclosure.

[0011] The present disclosure provides an integrated air source heat pump. As shown in FIGS. 1 to 5, the integrated air source heat pump includes a housing 100. The housing 100 forms an accommodating space 190.

[0012] An electrical box 200 is disposed at a top of the accommodating space 190. The electrical box 200 is disposed at the top, so that the accommodating space 190 may be fully utilized, which helps to reduce a volume of a whole machine and achieve a miniaturization design of the whole machine.

[0013] FIG. 6 is a diagram showing a structure of the electrical box, in accordance with some embodiments of the present disclosure; and FIG. 7 is an exploded view showing a structure of the electrical box, in accordance with some embodiments of the present disclosure. Referring to FIGS. 6 and 7, the electrical box 200 includes a main body of the electrical box. The main body of the electrical box includes a box body 210 and a box cover 220. The box body 210 and the box cover 220 are enclosed to form an inner space of the electrical box for installing components.

[0014] The box body 210 includes a bottom side plate 211, and a left side plate 212, a right side plate 213, a front side plate 215 and a rear side plate 214 that are disposed around the bottom side plate 211 and extend toward a direction of the box cover 220.

[0015] A bracket 24 is fixedly connected to the bottom side plate 211 by means of screws or the like. The bracket 24 includes a first bracket 241 and a second bracket 242. The first bracket 241 and the second bracket 242 provide support for installations of other components.

[0016] A driving board 231 is fixedly connected to a side of the first bracket 241 facing the box cover 220, and a radiator 270 is fixedly connected to a side of the first bracket 241 facing the bottom side plate 211 by means of screws or the like.

[0017] A main control board 232 is fixedly connected to a side of the second bracket 242 facing the box cover 220, and the main control board 232 is connected to a debugging board 234.

[0018] The driving board 231 generally integrates heat-generating components such as a central processing unit (CPU), a compressor driving chip, a fan driving chip and a silicon bridge. The main control board 232 generally integrates heat-generating components such as an electrolytic capacitor and a switching power chip. An operating current of the driving board 231 is high. An amount of heat generated by the driving board 231 is higher than an amount of heat generated by the main control board 232.

[0019] The first bracket 241 is located in a middle region of the inner space of the electrical box 200. The second bracket 242 is located in a right region, of the inner space of the electrical box 200, proximate to the right side plate 213. An opening 263 for the radiator 270 to protrude is disposed on the bottom side plate 211, and the radiator 270 protrudes from the opening 263.

[0020] Thus, in the inner space of the electrical box 200, the middle region in which the driving board 231 is disposed is a high heat region (marked as X1), and the right region in which the main control board 232 is disposed is a medium heat region (marked as X2).

[0021] The bottom side plate 211 is further provided with an inductance coil 233, which is located in a left region, of the inner space of the electrical box 200, proximate to the left side plate 212, and the left region is a low heat region (marked as X3).

[0022] A plurality of first air inlet holes 251 are disposed on the right side plate 213, a plurality of second air inlet holes 252 are disposed on the rear side plate 214, and a plurality of air outlet holes 253 are disposed on the left side plate 212.

[0023] The air enters inside the electrical box 200 from the first air inlet holes 251 and the second air inlet holes 252, sequentially flows through the medium heat region X2, the high heat region X1 and the low heat region X3, and then flows out from the air outlet holes 253, so that ventilation and heat dissipation of electrical components such as the main control board 232, the driving board 231 and the inductance coil 233 are achieved, energy consumption is low, and a heat dissipation effect is good.

[0024] Meanwhile, the radiator 270 performs synchronous heat dissipation on the driving board 231 with a high temperature, that is, double heat dissipation is performed on the driving board 231 by using the radiator 270 and natural wind, which may effectively and rapidly reduce a temperature of the high heat region X1.

[0025] A diagram showing a structure of the first bracket 241 may refer to FIG. 8. A plurality of support portions 243 are disposed on side plates around the first bracket 241 and in a middle region of the first bracket 241, and are used for abutting against the driving board 231, which enhances strength of the first bracket 241, and supports the driving board 231 to avoid a deformation of the driving board 231.

[0026] A plurality of claws 244 are also disposed on the side plates around the first bracket 241, and the plurality of claws 244 are used for being snapped with the driving board 231 to further enhance connection reliability of the driving board 231 and prevent the driving board 231 from tilting.

[0027] Similarly, the plurality of support portions 243 and the plurality of claws 244 are also disposed on the second bracket 242, which are used to enhance connection reliability of the main control board 232 and reduce a deformation of the main control board 232.

[0028] Apertures of the first air inlet holes 251, the second air inlet holes 252 and the air outlet holes 253 are preferably less than 2 mm, so that in a case where the ventilation is ensured, foreign matters such as insects may be prevented from entering inside the electrical box 200 to cause an accidental short circuit.

[0029] As shown in FIG. 6, the box cover 220 has a turn-up plate 221 bent downwards, and there is an air outlet gap 254 between the turn-up plate 221 and the air outlet holes 253. In a case where the ventilation is ensured, the turn-up plate 221 may prevent rainwater from entering inside the electrical box 200 to cause the short circuit, and improve reliability of the electrical box 200.

[0030] As shown in FIG. 7, a plurality of wiring holes 261 are disposed on the front side plate 215 and the rear side plate 214, and are used for wiring of internal electrical components. Wire binding brackets 262 are also disposed at positions proximate to the wiring holes 261. The wire binding brackets 262 are used for wire binding, so that the wiring is reliable, neat and orderly.

[0031] The electrical box 200 is applied to the integrated air source heat pump. In order to further enhance the heat dissipation effect of the electrical box 200, improve compactness of an internal structure of the air source heat pump, and reduce the volume of the whole machine, in the present disclosure, innovative improvements are made on an arrangement position of the electrical box 200, an assembled structure between the electrical box 200 and the air source heat pump, and an internal structure layout of the air source heat pump.

[0032] For the diagrams showing a structure of the integrated air source heat pump disclosed by the embodiments, reference may be made to FIGS. 1 to 5. FIG. 5 is a diagram showing a structure of the whole machine of the integrated air source heat pump. FIG. 1 is an exploded view showing a structure of the integrated air source heat pump. FIGS. 2 and 3 are diagrams showing layout structures of the internal components of the integrated air source heat pump, and in FIGS. 1 to 3, the housing 100 is omitted for convenience of showing the internal structure.

[0033] Referring to FIGS. 1 and 5, the integrated air source heat pump includes the housing 100. The housing 100 includes a bottom plate 130, a top plate 140, a left side wall, a right side wall 150, and a rear plate, and a front portion of the housing 100 is composed of a fan panel 160 and a maintenance plate 170.

[0034] As shown in FIG. 5, the fan panel 160 is disposed on a left side, and air outlets 161 are disposed on the fan panel 160 for air to go out. The maintenance plate 170 is disposed on a right side. In a case where the components inside the housing 100 need to be repaired, the maintenance plate 170 is detached.

[0035] Referring to FIGS. 1 to 3, a partition plate 300 and a support plate 400 extending along a vertical direction that are arranged separately are disposed on the bottom plate 130. The partition plate 300 divides the inner space of the housing 100 into a first installation space 110 and a second installation space 120 disposed on a left side and a right side. The support plate 400 is located in the second installation space 120 and is directly opposite to the partition plate 300.

[0036] A first heat exchanger 710 is disposed in the first installation space 110, a fan bracket 500 is disposed on the first heat exchanger 710, and fans 720 are disposed on the fan bracket 500.

[0037] A compressor 740, a refrigeration system container 770, a water pump 750, a second heat exchanger 730, wiring and tubes or the like are disposed in the second installation space 120.

[0038] The electrical box 200 is disposed at tops of the first installation space 110 and the second installation space 120. A left end of the electrical box 200 is fixedly connected to the fan bracket 500, a right end of the electrical box 200 is fixedly connected to the support plate 400, and the bottom side plate 211 of the electrical box 200 abuts against an upper end of the partition plate 300.

[0039] Both the radiator 270 and the debugging board 234 are located in the inner space of the housing 100.

[0040] FIG. 4 is a front view of the integrated air source heat pump (with the housing and components in the second installation space omitted), in accordance with some embodiments of the present disclosure. FIG. 4 shows a flow direction of air inside the air source heat pump when the fans 720 are operating. A part of outside air flows inside the electrical box 200 from the first air inlet holes 251 and the second air inlet holes 252 of the electrical box 200 due to wind pressure, and then flows out from the air outlet holes 253 of the electrical box 200.

[0041] Another part of the outside air enters the second installation space 120 from air inlets 151 on the housing 100 and flows upwards due to the wind pressure, then enters inside the electrical box 200 through the opening 263 on the bottom side plate 211 of the electrical box 200, and finally flows out from the air outlet holes 253. Air flows into the electrical box 200 from a rear side, a right side and a bottom side of the electrical box 200, and flows from the right end of the electrical box 200 to the left end of the electrical box 200, so as to dissipate the heat of the electrical components inside the electrical box 200, the heat dissipation effect is good and there is no space that cannot be dissipated heat.

[0042] In the present disclosure, the electrical box 200 is disposed at the top, so that the inner space of the housing 100 is fully utilized, which helps to reduce the volume of the whole machine and achieve the miniaturization design of the whole machine.

[0043] In a possible embodiment, as shown in FIG. 1, the first heat exchanger 710 is an L-shaped fin heat exchanger. The first heat exchanger 710 is fixedly connected to the bottom plate 130. A long side portion of the first heat exchanger 710 is located on a rear side of the first installation space 110, and a short side portion of the first heat exchanger 710 is located on a left side of the first installation space 110.

[0044] The fan bracket 500 extends along a height direction of the first heat exchanger 710. The fans 720 are located in a space enclosed by the L-shaped first heat exchanger 710 to improve a heat exchange efficiency. A side edge of the partition plate 300 proximate to the first heat exchanger 710 is fixedly connected to the first heat exchanger 710.

[0045] As shown in FIG. 1, the fan bracket 500 has a fan bracket vertical portion 510 and a fan bracket lateral portion 520. The fan bracket vertical portion 510 is fixedly connected to the first heat exchanger 710, and the fan bracket lateral portion 520 is located above the fans 720.

[0046] The fans 720 are fixedly connected to the fan bracket vertical portion 510, and the bottom side plate 211 of the electrical box 200 is fixedly connected to the fan bracket lateral portion 520 to fix the left end of the electrical box 200.

[0047] In some embodiments of the present disclosure, as shown in FIG. 1, the partition plate 300 has an L-shaped structure. The partition plate 300 includes a partition plate body 310 and a partition plate flange 320. The partition plate body 310 is fixedly connected to the first heat exchanger 710, and the partition plate flange 320 is connected to a front side wall of the housing 100.

[0048] The fan panel 160 located on the front side wall of the housing 100 is fixedly connected to the partition plate flange 320, and the maintenance plate 170 is detachably and fixedly connected to the partition plate flange 320.

[0049] Compared with a common C-shaped partition plate in the prior art, a length of the L-shaped first heat exchanger 710 is shortened, and the L-shaped first heat exchanger 710 is fixedly connected to the L-shaped partition plate 300, which helps to reduce an internal occupied space of the partition plate 300, and further helps to reduce the volume of the whole machine.

[0050] As shown in FIG. 2, a layout of the components in the second installation space 120 is as follows. The compressor 740 and the refrigeration system container 770 are fixedly connected to the bottom plate 130, the second heat exchanger 730 is fixedly connected to the support plate 400. The water pump 750 is located above the compressor 740 and the refrigeration system container 770, and the water pump 750 is fixedly disposed on a water pump bracket 760. An end of the water pump bracket 760 is fixedly connected to the partition plate 300, and another end of the water pump bracket 760 is fixedly connected to the support plate 400. The components are compact in layout and occupy small space.

[0051] The second heat exchanger 730 may be a water-fluorine plate heat exchanger, a shell-and-tube heat exchanger, a double pipe heat exchanger, or the like. The refrigeration system container 770 may be a liquid storage tank or the like.

[0052] As shown in FIGS. 1 and 2, a support beam 600 is also disposed in the second installation space 120. An end of the support beam 600 is fixedly connected to the partition plate 300, and another end of the support beam 600 is fixedly connected to the second heat exchanger 730.

[0053] The debugging board 234 is fixedly connected to the support beam 600, so as to achieve a fixed installation of the debugging board 234 and prevent the debugging board 234 from shaking.

[0054] The support plate 400, preferably, has an L-shaped structure. A lower end of the support plate 400 is fixedly installed on a right side edge and a rear side edge of the bottom plate 130, that is, the lower end of the support plate 400 is fixedly installed at a right rear corner of the bottom plate 130. Meanwhile, an upper end of the support plate 400 is fixedly connected to the right side plate 213 and the rear side plate 214 of the electrical box 200, so as to fix the right end of the electrical box 200.

[0055] So far, through a fixed connection between the left end of the electrical box 200 and the fan bracket lateral portion 520, a fixed connection between the right end of the electrical box 200 and the support plate 400, an abutting relationship between the bottom side plate 211 and the partition plate 300, and a fixed connection between the debugging board 234 and the support beam 600, a fixed installation of the electrical box 200 is achieved, so that the electrical box 200 is reliably and stably installed at a top of the air source heat pump, an existing structure of the air source heat pump is fully used for installation support, and small space is occupied.

[0056] The debugging board 234 is preferably located in the second installation space 120. During maintenance, the debugging board 234 may be repaired by detaching the maintenance plate 170 at the front portion, which is easy to operate.

[0057] A plurality of through holes (not shown) for ventilation are disposed both on the partition plate 300 and the support plate 400, so as to improve fluidity of air in the first installation space 110 and the second installation space 120, which facilitates the heat dissipation.

[0058] In a case where the bottom side plate 211 of the electrical box 200 abuts against the partition plate 300, in order to enhance an abutting firmness between the bottom side plate 211 of the electrical box 200 and the partition plate 300, and to enhance the heat dissipation effect of the radiator 270, a structure of the radiator 270 is also improved in the present disclosure.

[0059] For a diagram showing the structure of the radiator 270, reference may be made to FIG. 9. The radiator 270 includes a first heat dissipation fin group 271 and a second heat dissipation fin group 272 with a gap 273 therebetween.

[0060] The partition plate 300 is inserted in the gap 273 between the first heat dissipation fin group 271 and the second heat dissipation fin group 272, and abuts against the bottom side plate 211. The first heat dissipation fin group 271 is located in the first installation space 110, and the second heat dissipation fin group 272 is located in the second installation space 120.

[0061] The gap 273 between the first heat dissipation fin group 271 and the second heat dissipation fin group 272 has a limiting effect on the upper end of the partition plate 300, so as to prevent the upper end of the partition plate 300 from tilting or shaking.

[0062] Meanwhile, the radiator 270 designed in this way can make full use of top spaces of the first installation space 110 and the second installation space 120, so that the radiator 270 is made as large as possible to improve the heat dissipation efficiency.

[0063] In some embodiments of the present disclosure, the first heat dissipation fin group 271 is proximate to the left side plate 212, there is a slope portion 275 on a side of the first heat dissipation fin group 271 proximate to the fans 720. The slope portion 275 is used to provide a space for the fan bracket lateral portion 520, so as to facilitate the installation of the electrical box 200.

[0064] Meanwhile, the first heat dissipation fin group 271 is proximate to the fans 720, which also facilitates airflow at the fans 720 to dissipate heat from the first heat dissipation fin group 271, thereby improving the heat dissipation efficiency.

[0065] In some embodiments of the present disclosure, the second heat dissipation fin group 272 is proximate to the right side plate 213. At least one ventilation passage 274 for ventilation is disposed on the second heat dissipation fin group 272. In this embodiment, there are two ventilation passages 274. The ventilation passages 274 are perpendicular to fins of the second heat dissipation fin group 272.

[0066] Airflow flowing upwards from a bottom of the second installation space 120 will flow through an interior of the second heat dissipation fin group 272 through the ventilation passages 274, which helps to improve the heat dissipation efficiency of the second heat dissipation fin group 272.

[0067] FIG. 7 is an exploded view showing a structure of the electrical box, in accordance with some embodiments of the present disclosure. In a possible embodiment, referring to FIG. 7, the rear side plate 214 of the electrical box 200 includes a first rear side plate portion 2141, a second rear side plate portion 2142 and a third rear side plate portion 2143 that are sequentially connected to form a stepped structure. A distance between the first rear side plate portion 2141 and the front side plate 215 is greater than a distance between the third rear side plate portion 2143 and the front side plate 215. The second air inlets holes 252 are disposed on the first rear side plate portion 2141.

[0068] The rear side plate 214 is designed into the stepped structure, which is mainly to enable the electrical box 200 to be well matched and be connected with the internal components such as the first heat exchanger 710 and to reduce the occupied space.

[0069] After the electrical box 200 is installed in place, the first rear side plate portion 2141 is located on a right side of the first heat exchanger 710, so as to make full use of the top space of the second installation space 120. The stepped structure between the second rear side plate portion 2142 and the third rear side plate portion 2143 is used to provide a space for the fan bracket lateral portion 520, so that the rear side plate 214 can abut against the first heat exchanger 710 to reduce the occupied space.
