Description

Technical Field

[0001] This application relates to the technical field of heat pump equipment, and more particularly to a swimming pool heat pump equipment. Background Technology

[0002] In swimming pool heat pump units, the electrical box is the key carrier of the core electrical control unit. It needs to integrate various functional electrical components such as controllers, power modules, and relays to regulate the operating status of the heat pump unit. During the long-term operation of the heat pump unit, the high-power electrical components such as the internal power modules will continuously generate a large amount of heat, which is an inherent phenomenon in the operation of this type of equipment.

[0003] Currently, most electrical boxes widely used in the industry are single-chamber integrated structures with completely interconnected internal spaces. This structure has significant heat dissipation defects: heat generated by high-power electrical components rapidly diffuses throughout the entire internal space of the electrical box via air convection and thermal radiation, failing to achieve effective heat isolation. On the one hand, this causes temperature sensors, chips, and other thermistor-sensitive components inside the electrical box to operate in a high-temperature environment for extended periods, severely reducing their signal detection accuracy and operational stability, accelerating the aging process of these thermistor-sensitive components, and significantly shortening their lifespan. On the other hand, the pervasive heat diffusion causes the overall temperature of the electrical box to rise continuously, exceeding the safe operating temperature range of the electrical components, thereby increasing the risk of circuit failures and shutdown protection issues in the heat pump unit, seriously affecting the overall operational reliability and service life of the pool heat pump unit. Utility Model Content

[0004] The purpose of this application is to provide a swimming pool heat pump device to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a swimming pool heat pump device is provided, including: a housing and an electrical box. The housing is provided with a partition plate, which divides the internal space of the housing into a first cavity and a second cavity. A fan is installed in the first cavity. The electrical box is provided with a partition plate, which divides the internal space of the electrical box into a high-temperature zone and a low-temperature zone. The electrical box is installed inside the housing, and the partition plate is connected to the bottom of the electrical box to form a support. The high-temperature region is located within the first cavity.

[0006] Furthermore, the electrical box is provided with a heat dissipation vent, which connects the first cavity and the high-temperature area.

[0007] Furthermore, the heat dissipation vents are provided on at least two outer surfaces of the electrical box, and the heat dissipation vents on the two outer surfaces are capable of forming convection.

[0008] Furthermore, a portion of the low-temperature region is located within the first cavity, while the remainder is located within the second cavity.

[0009] Furthermore, the outer edge of the electrical box is formed with a folded edge, and the folded edge is provided with a first locking hole. The box body is provided with a second locking hole corresponding to the locking hole. The electrical box is fixed inside the box body by fasteners locked to the first locking hole and the second locking hole.

[0010] Furthermore, multiple first locking holes are provided, and the multiple first locking holes are spaced apart on the folded edges formed by the outer edges on both sides of the electrical box.

[0011] Furthermore, a motor bracket is provided inside the first cavity, and a horizontally arranged mounting portion is formed on the motor bracket. The mounting portion is at least partially located at the bottom of the electrical box to provide support.

[0012] Furthermore, the bottom of the electrical box is fixed to the mounting portion by fasteners.

[0013] Furthermore, the electrical box includes a box body, a first electronic control element, and a second electronic control element. The partition plate is integrally formed inside the box body. The first electronic control element is located in the high-temperature region, and the second electronic control element is located in the low-temperature region. The operating frequency of the first electronic control element is higher than that of the second electronic control element.

[0014] Furthermore, the electrical box is provided with heat dissipation holes, which connect the low-temperature region and the second cavity.

[0015] The beneficial effects of this application are as follows: By dividing the internal space of the electrical box into high-temperature and low-temperature zones using a partition, low-power electrical components can be placed in the low-temperature zone, completely avoiding the long-term high-temperature operation of low-power electrical components caused by the heat diffusion throughout the entire space in the traditional single-chamber structure, effectively ensuring their working stability and extending their service life; at the same time, the high-temperature zone of the electrical box is located in the first cavity where the fan is installed, which can achieve efficient heat dissipation with the help of the fan, quickly dissipating the heat generated by the high-power electrical components, preventing the heat from spreading to the entire space of the electrical box, effectively controlling the overall temperature of the electrical box, and significantly reducing the risk of equipment failure caused by excessive temperature.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1-5 As shown, this embodiment provides a swimming pool heat pump device, including: a housing 1 and an electrical box 2. The housing 1 is provided with a partition 3, which divides the internal space of the housing 1 into a first cavity 101 and a second cavity 102. A fan 4 is installed in the first cavity 101. The electrical box 2 is provided with a partition 201, which divides the internal space of the electrical box 2 into a high-temperature area 202 and a low-temperature area 203. The electrical box 2 is installed inside the housing 1, and the partition 3 is connected to the bottom of the electrical box 2 to form a support. The high-temperature region 202 is located within the first cavity 101.

[0023] Based on the above scheme, firstly, the internal functional areas of the electrical box 2 are physically divided by a partition 201, concentrating high-power thermoelectric components in the high-temperature area 202 and low-power thermoelectric components in the low-temperature area 203. The partition 201 acts as a barrier, cutting off the direct conduction and diffusion path of heat generated by high-power devices to the low-power device area. Secondly, the first cavity 101 formed by the partition 3 of the housing 1 not only serves as the mounting carrier for the fan 4 but also spatially matches the high-temperature area 202 of the electrical box 2, meaning the high-temperature area 202 of the electrical box 2 is precisely located within the high-temperature area 203. Within the first cavity 101, the forced convection airflow generated by the fan 4 during operation can precisely cover the high-temperature area 202. The forced airflow quickly removes the heat continuously generated by the high-power devices, preventing heat from accumulating and causing the temperature to rise in the high-temperature area 202. At the same time, the partition plate 3 supports the bottom of the electrical box 2, ensuring the stability of the electrical box 2's installation position and preventing the area from being misaligned due to equipment vibration, thus affecting the heat dissipation effect. It also further optimizes the airflow channel inside the enclosure 1, allowing the heat dissipation airflow to act more efficiently on the high-temperature area 202, forming a closed-loop thermal management mechanism of isolation, heat resistance, and directional heat dissipation.

[0024] Furthermore, the electrical box 2 is provided with a heat dissipation vent 204, which connects the first cavity 101 and the high-temperature region 202. From a working principle perspective, the heat dissipation vent 204 on the electrical box 2 serves as a dedicated communication channel between the first cavity 101 and the high-temperature region 202 of the electrical box 2, enabling directional guidance and precise flow of heat dissipation airflow: when the fan 4 inside the first cavity 101 operates, it generates forced convection airflow, which the heat dissipation vent 204 can directly guide into the high-temperature region 202 of the electrical box 2, allowing the airflow to directly contact the high-power electrical components within the high-temperature region 202, efficiently absorbing the heat continuously generated by the high-power electrical components; subsequently, the heat-carrying airflow can flow back to the first cavity 101 through the heat dissipation vent 204, forming a directional airflow circulation for the high-temperature region 202, thereby constructing a complete heat dissipation path and ensuring that the heat generated by the high-power electrical components can be continuously and directly carried away from the high-temperature region 202.

[0025] From the perspective of beneficial effects, the heat dissipation port 204 structure significantly enhances the heat dissipation efficiency of the high-temperature region 202 by constructing a direct airflow channel between the first cavity 101 and the high-temperature region 202. On the one hand, compared to the indirect heat dissipation method that relies solely on the high-temperature region 202 being located within the first cavity 101, the heat dissipation port 204 enables direct contact between the heat dissipation airflow and the heat source, significantly shortening the heat transfer path and reducing the residence time of heat in the high-temperature region 202. This allows for faster temperature control of the high-temperature region 202, preventing sudden temperature increases in high-power electrical components. On the other hand, the directional guidance of airflow by the heat dissipation port 204 prevents the disorderly diffusion of the heat dissipation airflow generated by the fan 4, ensuring that the heat dissipation energy is concentrated on the high-temperature region 202. This improves the utilization efficiency of heat dissipation resources and effectively prevents abnormal operation of electrical components caused by heat accumulation in the high-temperature region 202. At the same time, the more efficient heat dissipation effect further reduces the overall temperature load of the electrical box 2, reduces the risk of circuit failures caused by high temperatures, provides a more reliable guarantee for the long-term stable operation of high-power electrical components in the high-temperature region 202, and further extends the service life of the electrical box 2 and the entire electrical control system.

[0026] Furthermore, the heat dissipation vents 204 are at least disposed on two outer surfaces of the electrical box 2, and the heat dissipation vents 204 on the two outer surfaces can form convection. When the fan 4 in the first cavity 101 is running, the airflow can actively enter the high-temperature region 202 of the electrical box 2 through the heat dissipation vent 204 on one of the outer surfaces. After fully contacting the high-power electrical components and absorbing heat, it is then quickly discharged into the first cavity 101 through the heat dissipation vent 204 on the other opposite outer surface, forming a through-flow convection heat dissipation path. This convection design allows the heat dissipation airflow to penetrate the interior of the high-temperature region 202 in a specific direction, achieving airflow coverage of the entire high-temperature region 202, rather than just local circulation, ensuring that the high-power electrical components at all locations within the high-temperature region 202 can effectively contact the heat dissipation airflow.

[0027] The heat dissipation vent 204 can adopt a louver structure with the louver blades tilted at a specific angle. When the fan 4 generates airflow in the first cavity 101, the air inlet louver can smoothly guide the airflow into the high-temperature area 202 through the blade angle, reducing the resistance when the airflow enters and allowing the airflow to quickly fill the high-temperature area 202 and make full contact with the high-power electrical components. The airflow that has absorbed heat is then smoothly discharged through the tilted blades of the air outlet louver. At the same time, the arrangement direction of the blades can guide the airflow to flow along a preset trajectory, ensuring that the airflow covers all high-power electrical components in the high-temperature area 202. In addition, the heat dissipation vent 204 can also be designed as a grille structure. The grille-type heat dissipation vent 204 is composed of several parallel or intersecting strip-shaped ribs, with long strip-shaped or grid-shaped openings between the ribs. It needs to be set on at least two outer surfaces of the electrical box 2 to form convection. After the fan 4 in the first cavity 101 generates airflow, it can directly enter the high-temperature area 202 through the grille opening on one of the outer surfaces. After exchanging heat with the high-power electrical components, the airflow is discharged to the first cavity 101 through the grille opening on the other outer surface, completing the convection cycle. At the same time, the strip-shaped ribs can provide structural support for the heat dissipation port 204 without significantly obstructing the airflow, and prevent the outer surface of the electrical box 2 from reducing its strength due to the excessively large opening.

[0028] It is worth noting that part of the low-temperature region 203 is located within the first cavity 101, while the remainder is located within the second cavity 102. The portion of the low-temperature region 203 located within the first cavity 101 can directly contact the airflow generated by the operation of the fan 4, which can promptly remove the small amount of heat generated by the electrical components within this region, preventing a slow rise in local temperature. The portion of the low-temperature region 203 located within the second cavity 102, not being directly in the airflow zone of the fan 4, has a more stable cavity environment temperature, making it suitable for heat-sensitive electrical components that are sensitive to temperature fluctuations and do not require strong airflow for heat dissipation. Furthermore, thanks to the structural cooperation between the partition plate 3 and the electrical box 2, the cross-cavity layout of the low-temperature region 203 does not compromise its thermal isolation effect from the high-temperature region 202, while also allowing for flexible utilization of the internal space of the housing 1 to complete the layout.

[0029] In some embodiments, the outer edge of the electrical box 2 is formed with a folded edge 206, the folded edge 206 is provided with a first locking hole 207, and the housing 1 is provided with a second locking hole corresponding to the locking hole. The electrical box 2 is fixed inside the housing 1 by fasteners locking it to the first locking hole 207 and the second locking hole. The folded edge 206 formed on the outer edge of the electrical box 2 serves as the installation connection carrier. Its preset first locking hole 207 and the second locking hole on the housing 1 can be aligned and assembled to achieve position calibration. After the two locking holes are aligned, fasteners (such as bolts, screws, etc.) are inserted and locked, so that the folded edge 206 fits tightly with the housing 1, thereby fixing the electrical box 2 as a whole inside the housing 1. At the same time, the locking structure of the folded edge 206 and the middle partition 3 form a double fixing mechanism of bottom support and edge locking for the bottom support of the electrical box 2. The bottom middle partition 3 bears the vertical load of the electrical box 2, while the edge folded edge 206 locking restricts the horizontal displacement and vibration offset of the electrical box 2, ensuring that the electrical box 2 always maintains the preset installation position during equipment operation.

[0030] The housing 1 includes a front left panel 103, a front right panel 104, a maintenance plate, and a sprue plate 106 connected in sequence. The front left panel 103, the front right panel 104, the maintenance plate, and the sprue plate 106 are connected by a folded edge 206. The electrical box 2 serves as an internal support. Fasteners fix the front left panel 103, the front right panel 104, the maintenance plate, and the sprue plate 106 together to reduce assembly deviations and ensure quick disassembly and assembly of the middle maintenance plate 105.

[0031] Generally, multiple first locking holes 207 are provided, and these holes are spaced apart on the flanges 206 formed by the outer edges of both sides of the electrical box 2. During installation, the multiple first locking holes 207 on the flanges 206 on both sides can be precisely aligned with the second locking holes on both sides of the housing 1. Multiple fasteners are inserted into the corresponding locking holes on both sides and locked in place, so that the outer edges of both sides of the electrical box 2 are tightly fixed to the housing 1 through multiple points of connection. At the same time, the spaced locking holes can distribute the vertical load and horizontal vibration stress on the electrical box 2 to multiple connection points. With the support of the bottom partition plate 3, a three-dimensional fixed structure is formed, which restricts the displacement tendency of the electrical box 2 from different directions and ensures that the installation position is stable.

[0032] Preferably, a motor bracket 5 is provided inside the first cavity 101. A horizontally arranged mounting portion is formed on the motor bracket 5, and this mounting portion is at least partially located at the bottom of the electrical box 2 to provide support. The motor bracket 5 is used to mount the motor driving the fan 4. By providing a horizontally arranged mounting portion on the motor bracket 5, the mounting portion extends at least partially to the bottom of the electrical box 2, forming an additional support point for the electrical box 2. The planar structure of the horizontal mounting portion can form surface or line contact with the bottom of the electrical box 2, directly bearing part of the vertical load of the electrical box 2, forming multi-point collaborative support with the support of the middle partition 3 for the bottom of the electrical box 2. Moreover, the motor bracket 5 itself is fixedly connected to the housing 1, and the support position of its mounting portion is stable. Its structural rigidity can limit local settlement or shaking of the bottom of the electrical box 2, ensuring that the electrical box 2 maintains a horizontal posture in the vibration environment of equipment operation and avoiding tilting due to uneven force on the bottom.

[0033] Meanwhile, the bottom of the electrical box 2 is fixed to the mounting part by fasteners. The fasteners pass through and lock into the pre-set connection holes on the bottom of the electrical box 2 and the corresponding holes on the mounting part, further strengthening the load-bearing and fixing of the electrical box 2 by the mounting part in the vertical direction, while limiting the displacement of the bottom of the electrical box 2 relative to the mounting part in the horizontal direction. This structure, together with the locking and fixing of the edge fold 206 of the electrical box 2 and the bottom support of the partition plate 3, constructs a complete three-dimensional constraint system, limiting the displacement trend of the electrical box 2 under equipment operation vibration and external impact from different dimensions, ensuring the accuracy of its installation position.

[0034] In some embodiments, the electrical box 2 includes a box body 205, a first electronic control element 209, and a second electronic control element 210. A partition plate 201 is integrally formed inside the box body 205. The first electronic control element 209 is located in the high-temperature region 202, and the second electronic control element 210 is located in the low-temperature region 203. The operating frequency of the first electronic control element 209 is higher than that of the second electronic control element 210. This structure significantly improves the stability and layout rationality of the electronic control system: Firstly, the partition plate 201 is integrally formed with the box body 205, eliminating assembly gaps compared to a spliced ​​partition structure, resulting in greater thermal resistance and more reliably blocking heat conduction from the high-temperature region 202 to the low-temperature region 203. This ensures that the second electronic control element 210 in the low-temperature region 203 is always in a suitable temperature environment, effectively maintaining its operational stability. Secondly, the electronic control elements are arranged in zones according to their operating frequency (i.e., heat generation), concentrating the high-heat-generating first electronic control element 209 in the high-temperature region 202, which can efficiently work with the directional heat dissipation structure of the high-temperature region 202. In addition, the integrated partition plate 201 enhances the overall structural strength of the box 205, better protecting the internal electronic control components from equipment vibration. At the same time, the partition layout makes the wiring of the electronic control components more organized, which is convenient for later inspection and maintenance, and provides a dual guarantee in terms of structure and layout for the stable operation of the entire heat pump equipment's electronic control system.

[0035] Optionally, the electrical box 2 is provided with heat dissipation holes 208, which connect the low-temperature region 203 and the second cavity 102. Although the second electronic control component 210 in the low-temperature region 203 has limited heat generation, it will still generate a small amount of heat during long-term operation. If the heat accumulates in the low-temperature region 203, it may cause the local temperature to rise slowly. The heat dissipation holes 208 can utilize the natural temperature difference between the low-temperature region 203 and the second cavity 102 to drive the hot air in the low-temperature region 203 to flow naturally to the second cavity 102 through the heat dissipation holes 208. At the same time, the relatively cool air in the second cavity 102 can be replenished to the low-temperature region 203 through the heat dissipation holes 208, forming a natural convection circulation, thereby timely removing the small amount of heat generated by the second electronic control component 210 and preventing the low-temperature region 203 from failing at low temperatures.
