[0002] The electrical box of the heat pump outdoor unit is the main structure to ensure the normal and reliable operation of the mainboard. A key factor affecting the reliability of the mainboard is temperature, so heat dissipation has become a bottleneck problem for electronic components. Traditional electrical boxes are generally fully sealed structures. Although they can achieve relatively good sealing, they have poor heat dissipation. When operating under high load conditions, it is easy for the temperature of the electronic control components to rise too high, affecting the life of the machine. In addition, when producing traditional fully sealed electrical boxes, multiple sealing rubber rings need to be passed through, which often brings difficulties in production operations and affects production efficiency.

[0006] The sealing member is arranged between the box body and the shell of the heat pump. The sealing member is provided with at least one heat dissipation duct. One end of the heat dissipation duct is communicated with the compressor cavity, and the other end is communicated with the fan cavity of the heat pump.

[0007] Furthermore, the box body includes a bottom plate and a side plate, the bottom plate includes a first plate body located in the compressor cavity and a second plate body located in the fan cavity, and the side plate is installed on the edge of the bottom plate and connected to the inner wall of the heat pump casing.

[0008] Furthermore, the box body also includes a cover plate, which is installed on the top of the side plate and is tightly attached to the bottom of part of the heat dissipation duct, and the part of the heat dissipation duct that is not against the cover plate forms an air outlet connected to the fan cavity.

[0009] Furthermore, the cover plate corresponds to covering the upper part of the second plate body.

[0010] Furthermore, a water retaining portion is provided on a side of the cover plate away from the air outlet.

[0011] Furthermore, the water retaining portion is a folded edge formed by folding the cover plate upward at an angle β.

[0012] Furthermore, it also includes electrical components, which are installed on the base plate.

[0013] Furthermore, the sealing member is a flexible member.

[0014] Furthermore, the side plate, the bottom plate and the cover plate form a semi-enclosed structure, and the semi-enclosed structure includes a closed portion and an open portion, the open portion is arranged in the compressor cavity, and the closed portion is arranged in the fan cavity or the compressor cavity.

[0015] On the other hand, a heat pump is also provided, comprising the heat dissipation structure of the electrical box as described in any one of the above items.

[0016] Furthermore, it includes an outer shell, a middle partition, a compressor and a fan assembly, the middle partition is installed in the outer shell and divides the installation space of the outer shell into a compressor cavity and a fan cavity, the compressor is installed in the compressor cavity, the fan assembly is installed in the fan cavity, and the outer shell is provided with an air inlet connected to the compressor cavity.

[0017] The beneficial effects of the present application are as follows: the installation space opened in the box body is only connected to the compressor cavity and is isolated from the fan cavity. Therefore, the seal needs to be tightly fitted between the box body and the outer shell of the heat pump to ensure that the compressor cavity and the fan cavity are always in a relatively isolated state. Then, in this case, by opening a plurality of heat dissipation ducts on the seal, and connecting the two ends of the heat dissipation duct to the compressor cavity and the fan cavity respectively, when the fan in the fan cavity is turned on, the fan cavity will form a negative pressure, and the compressor cavity is at normal pressure.

DETAILED DESCRIPTION

[0028] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] like Figure 1-Figure 8 As shown, this embodiment provides a heat dissipation structure of an electrical box, including: a box body 1 and a seal 2, wherein an installation space is formed inside the box body 1, and the installation space is connected to the compressor cavity 1002 of the heat pump; the seal 2 is arranged between the box body 1 and the outer shell 10 of the heat pump, and at least one heat dissipation duct 3 is opened on the seal 2, one end of the heat dissipation duct 3 is connected to the compressor cavity 1002, and the other end is connected to the fan cavity 1001 of the heat pump.

[0032] Based on the above scheme, the installation space opened in the box body 1 is only connected to the compressor cavity 1002, and is isolated from the fan cavity 1001. Therefore, it is necessary to tightly set the seal 2 between the box body 1 and the outer casing 10 of the heat pump to ensure that the compressor cavity 1002 and the fan cavity 1001 are always in a relatively isolated state to prevent the compressor cavity airflow from flowing into the fan cavity through the gap between the outer casing 10 of the heat pump and the box body 1, thereby affecting the heat exchange of the heat pump unit. Then, in this case, by opening one or more heat dissipation ducts 3 on the seal 2, and connecting the two ends of the heat dissipation duct 3 to the compressor cavity 1002 and the fan cavity 1001 respectively, when the wind When the fan in the machine cavity 1001 is turned on, a negative pressure will be formed in the fan cavity 1001, and the compressor cavity 1002 will be at normal pressure. At this time, the air in the compressor cavity 1002 will flow to the fan cavity 1001 along the heat dissipation duct 3, and at the same time can take away the heat generated in the installation space, so as to achieve a reasonable and effective heat dissipation effect. Moreover, this heat dissipation method does not require the additional installation of a heat sink. Effective heat dissipation can be achieved only through the airflow generated during the normal operation of the heat pump, which can effectively save assembly costs and make full use of existing environmental resources. At the same time, because of the negative pressure effect, it can also effectively prevent water droplets or water flow from entering the open electrical box end.

[0033] It is worth noting that the seal 2 can be pasted on the box body 1 and then squeezed through the outer shell 10 of the heat pump to achieve a sealing effect; it can also be pasted inside the outer shell 10 of the heat pump and then squeezed through the box body 1 in turn.

[0034] The heat dissipation structure of the electrical box of this embodiment is exquisitely designed, effectively combining the structural characteristics of the box body 1, the seal 2 and the heat pump itself, realizing the heat exchange between the compressor cavity 1002 and the fan cavity 1001, without the need for an additional heat dissipation device, which not only reduces the production cost, but also makes full use of the airflow characteristics when the heat pump is running. Specifically, the installation space opened inside the box body 1 in the heat dissipation structure is connected to the compressor cavity 1002 of the heat pump, which means that the heat generated in the installation space can be directly conducted to the compressor cavity 1002, and the seal 2 is closely attached between the box body 1 and the shell 10 of the heat pump, forming a sealed isolation layer, ensuring that the airflow between the compressor cavity 1002 and the fan cavity 1001 will not be directly exchanged, and maintaining their respective independence. More importantly, a plurality of heat dissipation ducts 3 are designed on the seal 2. One end of these heat dissipation ducts 3 is connected to the compressor cavity 1002, and the other end is connected to the fan cavity 1001. When the fan of the heat pump is started, negative pressure will be formed inside the fan chamber 1001, while the compressor chamber 1002 maintains normal pressure. Due to the pressure difference, the hot air in the compressor chamber 1002 will flow along the heat dissipation duct 3 to the fan chamber 1001, and at the same time take away the heat in the installation space. This heat dissipation method makes full use of the airflow characteristics during normal operation of the heat pump, without the need for additional heat sinks or fans, which not only reduces production costs but also improves heat dissipation efficiency. At the same time, since the heat dissipation duct 3 is formed by the cooperation of the seal 2, the box body 1 and the housing 10, installation and maintenance are relatively simple, which improves the overall performance and service life of the product.

[0035] It should be noted that if Figure 1 , Figure 3 As shown, the heat dissipation duct 3 is specifically formed by the cooperation between the seal 2, the box body 1 and the shell 10. A plurality of strip channels are hollowed out in the seal 2, and then the box body 1 and the shell 10 are respectively abutted on opposite sides of the strip channel, which is equivalent to combining a heat dissipation duct 3 between the seal 2, the box body 1 and the shell 10. At the same time, when the box body 1 is abutted, at least part of it needs to be staggered with the strip channel, so that the formed heat dissipation duct 3 can be connected with the fan cavity 1001, and air can circulate.

[0036] Furthermore, if Figure 5 , Figure 6As shown, the box body 1 includes a bottom plate 101 and a side plate 102, the bottom plate 101 includes a first plate body located in the compressor cavity 1002 and a second plate body located in the fan cavity 1001, and the side plate 102 is installed on the edge of the bottom plate 101 and connected to the inner wall of the heat pump housing 10. In this scheme, the heat dissipation structure of the electrical box is further optimized and refined. In particular, the design of the box body 1 is divided into two parts: the bottom plate 101 and the side plate 102. Specifically, the bottom plate 101 is designed into two parts: the first plate body is located in the compressor cavity 1002, and the second plate body is located in the fan cavity 1001. Such a design can ensure that the bottom plate 101 fits tightly to the corresponding position inside the heat pump, effectively isolating the two cavities. At the same time, since the bottom plate 101 is directly in contact with the internal structure of the heat pump, it can more effectively conduct and disperse the heat generated in the installation space. The side panel 102 is installed on the edge of the bottom panel 101 and connected to the inner wall of the heat pump housing 10. This connection method not only enhances the overall stability of the box body 1, but also further strengthens the isolation effect between the compressor cavity 1002 and the fan cavity 1001. The design of the side panel 102 also takes into account the sealing and airflow guidance, ensuring that the heat dissipation duct 3 can smoothly connect the compressor cavity 1002 and the fan cavity 1001, while preventing other unnecessary heat exchanges from occurring. In general, through the combined design of the bottom panel 101 and the side panel 102, the heat dissipation structure of the electrical box of this embodiment not only realizes efficient heat conduction and heat dissipation, but also ensures effective isolation between the compressor cavity 1002 and the fan cavity 1001. This design not only improves the overall performance of the heat pump, but also reduces the production cost and maintenance difficulty, providing a more optimized and reliable solution for the design and production of heat pump products.

[0037] Furthermore, the box body 1 also includes a cover plate 103, which is installed at the top of the side plate 102 and is close to the bottom of part of the heat dissipation duct 3. The part of the heat dissipation duct 3 that is not against the cover plate 103 forms an air outlet 4 connected to the fan chamber 1001. The design of the cover plate 103 is added in this scheme, which further improves the heat dissipation effect and structural stability. Specifically, the cover plate 103 is installed at the top of the side plate 102 and is close to the bottom of part of the heat dissipation duct 3. This installation method ensures that the top of the heat dissipation duct 3 is effectively closed, avoiding the escape of hot air, thereby enhancing the heat dissipation effect. At the same time, due to the presence of the cover plate 103, the structure of the heat dissipation duct 3 is further stabilized, and the structure of the entire electrical box is also more solid and reliable. It is worth noting that the heat dissipation duct 3 is not completely against the cover plate 103, but leaves a certain space. These parts that are not in contact with the cover plate 103 form an air outlet 4 connected to the fan chamber 1001. This design allows hot air to flow in the heat dissipation duct 3 and then smoothly enter the fan chamber 1001 through the air outlet 4, and then be discharged by the fan, thereby achieving effective transfer and dissipation of heat. By adding the design of the cover plate 103, the heat dissipation structure of the electrical box of this embodiment not only improves the heat dissipation efficiency, but also enhances the stability and reliability of the structure. This design fully considers the airflow characteristics and heat dissipation requirements inside the heat pump, and provides an effective solution for the performance improvement and cost control of heat pump products. The housing 10 includes a top cover 1004 set at the top, and the top cover 1004 and the cover plate 103 abut against the seal 2 from top and bottom to form a heat dissipation duct 3.

[0038] At the same time, the cover plate 103 corresponds to the upper part of the second plate body. The further optimization of the heat dissipation structure of the electrical box is reflected in the arrangement position of the cover plate 103. The main purpose is to prevent water from flowing back or splashing into the compressor cavity or the electrical box from the condensed water in the fan cavity. In addition, such a design has the following advantages: First, since the second plate body is located in the fan cavity 1001, the cover plate 103 covering it can effectively isolate the fan cavity 1001 from other parts inside the electrical box, thereby preventing unnecessary heat exchange from occurring, which helps to maintain the air flow in the fan cavity 1001 stable and improve the heat dissipation efficiency. Secondly, by tightly combining the cover plate 103 with the second plate body, a relatively closed space can be formed, which helps to reduce the heat loss through other channels, so that more heat enters the fan cavity 1001 through the heat dissipation duct 3, thereby further enhancing the heat dissipation effect. In addition, the cover plate 103 covering the upper part of the second plate body can also enhance the overall structural stability of the electrical box. Since the cover plate 103 is tightly combined with the side plate 102, the bottom plate 101 and other components, it can serve as a reinforcement to improve the rigidity and anti-vibration performance of the entire electrical box.

[0039] As an optional specific implementation scheme, the seal 2 can be set on the side in addition to the top of the box body 1. When the seal 2 is set on the side, the heat dissipation duct 3 formed is correspondingly on the side, such as on the front panel or the rear panel of the outer shell 10.

[0040] In addition, the side plate 102, the bottom plate 101 and the cover plate 103 form a semi-enclosed structure, and the semi-enclosed structure includes a closed portion 105 and an open portion 106, wherein the open portion 106 is disposed in the compressor cavity 1002, and the closed portion 105 is disposed in the fan cavity 1001, or the open portion 106 is disposed in the compressor cavity 1002, and similarly the closed portion 105 is also disposed in the compressor cavity 1002. In simple terms, the electrical box of the semi-enclosed structure can be disposed in its entirety in the compressor cavity 1002, or it can be disposed partially in the fan cavity 1001 and partially in the compressor cavity 1002, and the actual installation position can be adjusted according to the adaptability of the position of the internal structural components of the heat pump unit.

[0041] In some embodiments, a water retaining portion 1031 is provided on the side of the cover plate 103 away from the air outlet 4. The water retaining portion 1031 is provided on the side of the cover plate 103 away from the air outlet 4, which means that the water retaining portion 1031 directly faces the fan cavity 1001, and can effectively prevent external humid air or moisture from entering the interior of the electrical box. The material and design of the water retaining portion 1031 should have excellent waterproof performance to ensure that it can effectively prevent moisture penetration under various environmental conditions. The provision of the water retaining portion 1031 not only enhances the waterproof ability of the electrical box, but also further improves the reliability of its overall structure. In a humid or rainy environment, the electrical box is easily affected by moisture, resulting in damage to internal components or circuit short circuits, and the presence of the water retaining portion 1031 can effectively isolate moisture, including the backflow of condensed water and the water thrown out by the rotation of the fan, protecting the electrical components 104 inside the electrical box from damage. Moreover, the design of the water retaining portion 1031 also takes into account the influence of heat dissipation performance. It ensures that while blocking moisture, it will not excessively hinder the transfer and dissipation of heat. Therefore, comprehensive consideration is needed in the material selection and structural design of the water retaining portion 1031 to achieve a balance between waterproofing and heat dissipation.

[0042] Specifically, Figure 7As shown, the water retaining portion 1031 is a folded edge formed by folding the cover plate 103 upward at an angle β. The formation of the folded edge allows the cover plate 103 to form an upward protrusion at the edge portion, so that it can effectively prevent moisture from the top or side from entering the interior of the electrical box, wherein the specific value of the angle β is adjusted according to the actual product design needs, and the specific value range is between 30°-140°. The folded folded edge can ensure a continuous, seamless connection with the main body of the cover plate 103, further enhancing the waterproof effect. At the same time, the design of the folded edge does not affect the ventilation performance of the heat dissipation duct 3. Since the folded edge is only folded along the edge of the cover plate 103 and does not completely cover the opening of the heat dissipation duct 3, the air can still flow smoothly through the heat dissipation duct 3, ensuring the heat dissipation effect. In addition, the existence of the folded edge also enhances the mechanical strength of the cover plate 103, making the entire electrical box more sturdy and durable. During assembly and use, the folded edge can effectively resist external impact and vibration, and protect the electrical components 104 inside the electrical box from damage. In summary, by designing the water retaining portion 1031 as a folded edge formed by folding the cover plate 103 upward, the heat dissipation structure of the electrical box of this embodiment not only achieves a waterproof function, but also maintains good heat dissipation performance and mechanical strength. This design is both practical and economical, and helps to improve the overall performance and reliability of the heat pump product.

[0043] In addition, it also includes electrical components 104, which are installed on the base plate 101. In this embodiment, the heat dissipation structure of the electrical box further integrates electrical components 104, which are installed on the base plate 101. This design not only improves the utilization efficiency of space, but also makes the functions of the electrical box more comprehensive and rich. The selection and installation position of the electrical components 104 are carefully considered. They are placed on the base plate 101, which can not only ensure the stability and safety of the electrical components 104, but also facilitate heat dissipation and maintenance. The design of the base plate 101 also fully considers the heat dissipation requirements of the electrical components 104. Through a reasonable heat conduction structure and heat dissipation design, it is ensured that the heat generated by the electrical components 104 during operation can be dissipated in a timely and effective manner to prevent performance degradation or damage caused by overheating. At the same time, since the electrical components 104 are directly installed on the base plate 101, the positional relationship between them and the heat dissipation duct 3 is also optimized. This allows the heat generated by the electrical components 104 during operation to be discharged more directly through the heat dissipation duct 3, further improving the heat dissipation efficiency. In addition, this design also facilitates maintenance and management of the electrical components 104. When the electrical components 104 need to be repaired or replaced, the bottom plate 101 can be directly operated without disassembling the entire electrical box, which greatly simplifies the maintenance process and improves work efficiency.

[0044] Preferably, the seal 2 is a flexible member, and the flexible member includes rubber, foam, sponge or silicone. In this scheme, sponge is preferably used as the material of the seal 2. As a common sealing and buffering material, sponge has many advantages, making it an ideal choice for the heat dissipation structure of the electrical box. First, the sponge has good sealing performance. Its unique material structure enables it to fit tightly between the box body 1 and the heat pump housing 10, effectively isolating the compressor cavity 1002 and the fan cavity 1001, and preventing unnecessary exchange of heat and airflow. This excellent sealing performance ensures the integrity and effectiveness of the heat dissipation duct 3, ensuring that heat can flow according to the designed path to achieve efficient heat dissipation. Second, the sponge has good compressibility and resilience. During the installation process, the sponge can be compressed to adapt to the gap between the box body 1 and the housing 10 of different shapes and sizes to ensure a close fit. At the same time, the sponge can quickly return to its original state after being subjected to pressure, maintain a long-term and stable sealing effect, and is not prone to problems such as aging or deformation. Third, the sponge also has certain sound absorption and shock absorption effects. During the operation of the heat pump, components such as the compressor and fan will generate noise and vibration. The sponge as a seal 2 can effectively absorb these noises and reduce vibration transmission, thereby improving the user experience.

[0045] It is worth mentioning that in the traditional design of electrical boxes, wire holes and wire sheaths are usually required to accommodate and protect the wires passing through the electrical box. However, this design not only increases the complexity and cost of the electrical box, but may also cause many inconveniences during production and maintenance. In contrast, the electrical box in this embodiment cancels the design of wire holes and wire sheaths, and optimizes the internal structure and layout of the electrical box so that the wires can be directly and orderly arranged inside the electrical box without passing through any holes or sheaths. This design without wire holes and wire sheaths brings the following significant advantages: First, it simplifies the structure of the electrical box and reduces the number of assembly steps and parts in the production process. This not only reduces production costs, but also improves production efficiency. Secondly, due to the lack of restrictions on wire holes and wire sheaths, wires can be arranged more flexibly and freely inside the electrical box. This helps to reduce the bending and twisting of wires, reduce the risk of wire damage, and improve the reliability and stability of wiring. In addition, the design without wire holes and wire sheaths also makes the electrical box easier to clean and maintain. During the cleaning process, there is no need to worry about the wires being stuck or damaged by the wire holes or sheaths; during maintenance, it is also more convenient to check and replace the wires.
