[0050] like Figures 1 to 2 As shown, according to a first aspect of the present invention, an electrical control box assembly 50 is provided. Figure 1 A schematic diagram of the electrical control box assembly 50 according to an embodiment of the present invention is shown. Figure 2 for Figure 1 The diagram shows the internal structure of the electrical control box assembly 50 (the cover 52 is not shown). The electrical control box assembly 50 is used in the heat pump water heater 1 and is a component of the heat pump water heater 1. The heat pump water heater 1 includes the electrical control box assembly 50 and the housing 10. The electrical control box assembly 50 includes an electrical control box 51, a cover 52, a first circuit board 53, a heating element 56, and a heat-conducting element 59. The electrical control box 51 forms an installation cavity 511 with an opening. The cover 52 is connected to the electrical control box 51 and seals the opening. The cover 52 faces the housing 10 and is thermally connected to the housing 10. The first circuit board 53 is located in the installation cavity 511. The heating element 56 is located on the first circuit board 53. The heat-conducting element 59 is located on the side of the heating element 56 facing the cover 52. The heating element 56 and the cover 52 are thermally connected through the heat-conducting element 59.
[0051] It should be noted that the electrical control box assembly 50 can be installed on the inner surface of the enclosure 10. In this case, the opening of the electrical control box 51 faces the enclosure 10. That is, after the cover 52 is connected to the electrical control box 51, the cover 52 can be in contact with the enclosure 10 to increase the heat transfer effect between the cover 52 and the enclosure 10. Alternatively, the gap between the cover 52 and the enclosure 10 can be smaller, which can also dissipate the heat of the cover 52 through the enclosure 10 via natural convection.
[0052] In addition to the heating element 56, the first circuit board 53 can also be equipped with electrical components such as capacitors and resistors to realize the control function of the electrical control box assembly 50. The layout of the electrical components on the first circuit board 53 will not be described in detail here.
[0053] The heating element 56 here can be an inductor or other electronic components with heating functions. An inductor is a component that generates an electromagnetic field through electromagnetic induction. Normally, an inductor generates heat during operation, which accumulates inside the control box assembly 50. Since the interior of a typical control box assembly 50 is a closed space, its heat dissipation rate is relatively slow. Therefore, this invention adds a heat-conducting element 59 inside the control box assembly 50 and positions it on the side of the heating element 56 facing the cover 52. The heating element 56 and the cover 52 are thermally connected through the heat-conducting element 59, allowing the cover 52 to dissipate the heat generated by the heating element 56 to the outside of the control box assembly 50, thereby achieving rapid heat dissipation of the control box assembly 50.
[0054] According to the present invention, the electrical control box assembly 50 is provided with an electrical control box 51, a box cover 52, a first circuit board 53, a heating element 56, and a heat-conducting element 59. The box cover 52 is positioned facing the housing 10 and is thermally connected to the housing 10. The heating element 56 is disposed on the first circuit board 53, and the heat-conducting element 59 is disposed on the side of the heating element 56 facing the box cover 52. The heating element 56 and the box cover 52 are thermally connected through the heat-conducting element 59. Thus, the heat generated by the heating element 56 can be sequentially transferred to the box cover 52 and the housing 10 through the heat-conducting element 59, and then dissipated outward through the housing 10, thereby achieving rapid heat dissipation of the electrical control box assembly 50.
[0055] Specifically, the inductor is provided with a coil, and the coil of the inductor is thermally connected to the heat-conducting component 59 and the cover 52. Thus, the heat generated by the coil of the inductor is transferred to the heat-conducting component 59 and the cover 52 in sequence, and the heat is quickly dissipated through the cover 52.
[0056] Specifically, there can be two or more inductors. The coil of each inductor can be thermally connected to the cover 52 through the heat-conducting element 59. There can be one cover 52 and one heat-conducting element 59. In this case, the coil of each inductor is thermally connected to the cover 52 through this one heat-conducting element 59, thereby transferring the heat generated by each inductor out.
[0057] Alternatively, the number of heat-conducting elements 59 can be two or more, wherein each heat-conducting element 59 is thermally connected to the cover 52. Figure 2 In this design, there are two inductors and two heat-conducting elements 59. One inductor is in contact with one heat-conducting element 59, and the sensor coil is thermally connected to the cover 52 through this heat-conducting element 59. The other inductor is in contact with the other heat-conducting element 59, and the sensor coil is thermally connected to the cover 52 through this heat-conducting element 59. This arrangement allows for heat dissipation for each inductor.
[0058] The following will combine Figures 3 to 6 The structure of the heat-conducting component 59 is described in detail below. Figure 3 for Figure 1 A schematic diagram of the connection structure between the heat-conducting element 59 and the heating element 56 of the electrical control box assembly 50 described herein. Figure 4 for Figure 3 Another connection structure diagram of the heat-conducting element 59 and the heating element 56 of the electrical control box assembly 50 described herein. Figure 5 for Figure 3 Another connection structure diagram of the heat-conducting element 59 and the heating element 56 of the electrical control box assembly 50 described herein. Figure 6 for Figure 5 The diagram shows the specific structure of the heat-conducting component 59 of the electrical control box assembly 50.
[0059] Optionally, such as Figure 3 As shown, the heat-conducting element 59 has a plate-like structure, and the heat-generating element 56 has a plate-like structure on the surface facing the cover 52 and / or on the surface facing the cover 52 towards the heat-generating element 56. Here, the heat-conducting element 59 has a plate-like structure, meaning it is a flat plate. There can be one heat-conducting element 59, which can be located on the heat-generating element 56 or on the cover 52. Alternatively, there can be two heat-conducting elements 59, one on the heat-generating element 56 and the other on the cover 52.
[0060] Preferably, there is one heat-conducting element 59, and the heat-conducting element 59 is disposed on the inner surface of the cover 52. When the cover 52 is connected to the electrical control box 51, the heat-conducting element 59 can be in contact with the heating element 56, so that the heat generated by the heating element 56 can be quickly transferred to the heat-conducting element 59. The heat of the heat-conducting element 59 is transferred to the outside of the electrical control box assembly 50 through the cover 52 and the box body 10 in contact with the cover 52, thereby realizing heat dissipation of the electrical control box assembly 50.
[0061] Optionally, the plate-like structure is bonded to the surface of the cover 52 facing the heating element 56 and is in contact with the heating element 56, thereby achieving a thermally conductive connection with the heating element 56. Alternatively, the plate-like structure can also be fixed to the surface of the cover 52 facing the heating element 56 by welding, thereby reducing the probability of the plate-like structure falling off the cover 52. The plate-like structure can be made of a thermally conductive and insulating material, such as alumina, etc. The welding method can be brazing, diffusion welding, or fusion welding.
[0062] The plate-like structure can be bonded to the inner surface of the box cover 52 using thermally conductive adhesive. The thermally conductive adhesive not only has adhesive properties but also thermal conductivity, and will not reduce the thermal conductivity of the plate-like structure.
[0063] Optionally, such as Figure 4As shown, the heat-conducting component 59 has a box-shaped structure, which covers at least part of the heating component 56. The box-shaped structure can be an open-end box-shaped structure. The box-shaped structure covers the outside of the heating component 56 and is thermally connected to the heating component 56. The inner surface of the box-shaped structure is in contact with the heating component 56, thereby increasing the thermal conductivity between the heating component 56 and the box-shaped structure.
[0064] Specifically, the four sides and the top surface of the box-shaped structure can all contact the heating element 56, thereby increasing the contact area between the box-shaped structure and the heating element 56 and increasing the heat conduction efficiency between the heating element 56 and the box-shaped structure.
[0065] Understandably, the box-shaped structure here is a component made of thermally conductive material, possessing both thermal conductivity and insulation properties. Furthermore, the internal shape and dimensions of the box-shaped structure can be identical to the shape and structure of the thermally conductive element 59, thereby increasing the contact area between the box-shaped structure and the thermally conductive element 59.
[0066] Optionally, the box-shaped structure is provided with thermally conductive insulating adhesive, and the heating element 56 is bonded to the heat-conducting element 59 through the thermally conductive insulating adhesive. The thermally conductive insulating adhesive can be a solid adhesive, which fills the internal space of the box-shaped structure. By providing thermally conductive insulating adhesive inside the box-shaped structure, the heat transfer efficiency between the box-shaped structure and the heating element 56 can be improved through the thermally conductive insulating adhesive, so that the heat generated by the heating element 56 can be quickly discharged to the outside of the electrical control box assembly 50 through the box-shaped structure, the box cover 52 and the box body 10.
[0067] Optionally, a heat dissipation surface 591 is formed on the side of the box-shaped structure opposite to the heat-generating element 56. At least a portion of the heat dissipation surface 591 contacts the cover 52. Here, the heat dissipation surface 591 refers to the surface of the box-shaped structure facing the cover 52. It is possible that all of the heat dissipation surface 591 contacts the cover 52, or only a portion of the heat dissipation surface 591 contacts the cover 52. Of course, preferably, all of the heat dissipation surface 591 contacts the cover 52, thereby increasing the contact area between the box-shaped structure and the cover 52 and increasing the efficiency of heat dissipation from the heat-generating element 56.
[0068] Optionally, the heat dissipation surface 591 is a planar structure. This is because the cover 52 is usually a flat structure. Therefore, in order to increase the contact area between the cover 52 and the heat dissipation surface 591, the heat dissipation surface 591 is set to a planar structure. Alternatively, when the cover 52 adopts a curved structure, the heat dissipation surface 591 can also adopt a curved structure adapted to the cover 52, thereby allowing the heat dissipation surface 591 to contact the cover 52 and increasing the heat transfer efficiency between the heat dissipation surface 591 and the cover 52.
[0069] Optionally, such as Figure 5 and Figure 6As shown, the heat-conducting component 59 includes a heat pipe, which includes an evaporation section 592 and a condensation section 593 that are interconnected. At least a portion of the evaporation section 592 is thermally connected to the heating element 56, and the condensation section 593 is located outside the electrical control box assembly 50.
[0070] It should be noted that a heat pipe is a heat transfer element with extremely high thermal conductivity. It transfers heat through the evaporation and condensation of liquid within a fully enclosed vacuum tube. Utilizing fluid principles such as capillary action, it achieves a cooling effect similar to a refrigerator compressor. It possesses a series of advantages, including high thermal conductivity, excellent isothermal properties, variable heat flux density, reversible heat flow direction, long-distance heat transfer capability, isothermal characteristics (controllable heat pipe), and the performance of a thermal diode and thermal switch. Furthermore, heat exchangers composed of heat pipes offer advantages such as high heat transfer efficiency, compact structure, and low fluid resistance. One end of the heat pipe is the evaporation section 592, and the other end is the condensation section 593. Depending on the application, an adiabatic section (not shown) is placed between the two sections. When one end of the heat pipe is heated, the liquid in the capillary wick evaporates and vaporizes. The vapor flows to the other end under a small pressure difference, releasing heat and condensing back into liquid. The liquid then flows back along the porous material due to capillary action. This cycle continues, with heat being transferred from one end of the heat pipe to the other, thus achieving heat transfer. In other words, heat is transferred from the evaporation section 592 to the condensation section 593, thereby achieving heat dissipation for the heating element 56.
[0071] Optionally, the heat pipe has a ring structure, with the evaporation section 592 and the condensation section 593 forming a ring structure.
[0072] The annular structure here can be a rectangular annular structure or a circular annular structure. The evaporation section 592 is fitted to the heating element 56, the condensation section 593 is located outside the electrical control box assembly 50, the heating element 56 can penetrate through the electrical control box 51, and a sealing structure can be provided at the connection position between the heat pipe and the electrical control box 51 to achieve sealing of the electrical control box 51.
[0073] The evaporation section 592 and the heating element 56 are fitted together at one end along the axial direction, which facilitates the stable connection between the evaporation section 592 and the heating element 56, and allows the heat pipe to pass through the electrical control box 51. Thus, the heat generated in the heating element 56 can be transferred through the heat pipe, and the heat inside the electrical control box 51 can be discharged to the outside of the electrical control box 51.
[0074] It is understandable that, in addition to these three structures, the heat-conducting component 59 can also adopt other heat-conducting structures, which will not be explained here.
[0075] The electrical control box assembly 50 here uses a heat-conducting component 59, which is in contact with the heat-generating component 56. The heat can be dissipated from the electrical control box assembly 50 through the heat-conducting component 59, the box cover 52 and the housing 10 in sequence, thus achieving rapid heat dissipation of the electrical control box assembly 50.

Figure 8 The diagram schematically illustrates a partial structural schematic of a heat pump water heater according to an embodiment of the present invention from a first-view perspective. Figure 9 The diagram schematically shows a partial structural schematic of a heat pump water heater according to an embodiment of the present invention from a second perspective. The second aspect of the embodiment of the present invention provides a heat pump water heater 1, which includes a housing 10 and an electrical control box assembly 50 mentioned in the above embodiment, with at least a portion of the electrical control box assembly 50 disposed inside the housing 10.
[0077] Specifically, the electrical control box assembly 50 is detachably connected to the inner surface of the housing 10, thereby enabling the electrical control box assembly 50 to be detachably installed on the housing 10. The specific connection method can be screw connection or riveting and other methods for fixing.
[0078] Optionally, the heat pump water heater 1 further includes a first heat exchanger 20, a second heat exchanger 30, a compressor 40, a fan assembly 60, and a wired controller assembly 70. The housing 10 houses and supports the various functional components of the heat pump water heater 1. At least a portion of the electrical control box assembly 50 is detachably connected to the interior of the housing 10 and is electrically or signal-connected to the compressor 40, fan assembly 60, and wired controller assembly 70 to coordinate and control the operating logic of each functional component.
