[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0036] A heat pump is a device that transfers heat from a low-temperature environment to a high-temperature environment. It utilizes the circulation of refrigerant in a closed loop to absorb heat from the outside (such as air, water, or soil) and transfer it to the area requiring heating. Heat pumps can provide heating, cooling, and even hot water supply, and have high energy efficiency. Heat pumps are equipped with electronic control components to control the start and stop of certain structures. However, currently, the heat dissipation efficiency and rate of most electronic control components are relatively low.
[0037] Based on this, please refer to Figure 1 and Figure 2 The heat pump 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. The heat pump 1000 can improve the heat dissipation efficiency and rate of the electronic control component 300.
[0038] Figure 1 This is a schematic diagram of the heat pump 1000 provided in an embodiment of the present invention from a first-view perspective; Figure 2 This is a schematic diagram from a second perspective of the heat pump 1000 provided in an embodiment of this utility model. (See diagram below.) Figure 1 and Figure 2As shown, the heat pump 1000 in this embodiment includes a housing 100, a partition 200, an electrical control component 300, a protective cover 400, and a fan assembly 600. The housing 100 has an installation space 110. The partition 200 is disposed inside the housing 100 and divides the installation space 110 into a fan compartment 111 and a compressor compartment 112. An air inlet 121 is provided on one side of the housing 100 of the compressor compartment 112. The electrical control component 300 is disposed on the partition 200 and is located in the fan compartment 111. The protective cover 400 is connected to the partition 200 and is used to cover the electrical control component 300. A vent 500 is formed at the connection between the protective cover 400 and the partition 200. The vent 500 is used to deliver air from the compressor compartment 112 to the fan compartment 111 after passing through the electrical control component 300. Furthermore, the fan assembly 600 is connected to the partition 200 and is positioned below the electronic control assembly 300. When the heat pump 1000 is operating, air is drawn in through the air inlet 121, enters the compressor compartment 112, then flows through the vent 500 to the electronic control assembly 300, where it dissipates heat before flowing to the fan compartment 111 and finally being exhausted. When the temperature of the electronic control assembly 300 is lower than a preset temperature, the fan assembly 600 below the electronic control assembly 300 does not start; when the temperature of the electronic control assembly 300 is higher than the preset temperature, the fan assembly 600 below the electronic control assembly 300 starts to accelerate airflow, thereby improving the heat dissipation rate and efficiency.
[0039] By setting up the vent 500, air entering the compressor compartment 112 from the air inlet 121 can only enter the fan compartment 111 through the vent 500. Furthermore, by setting up the protective cover 400, the air entering the fan compartment 111 is ensured to pass completely through the electronic control component 300 before being delivered to the fan compartment 111, thus improving the heat dissipation efficiency and rate of the electronic control component 300. By setting up the fan assembly 600 below the electronic control component 300, the fan assembly 600 can be activated when the electronic control component 300 temperature is high, thereby increasing the airflow speed and dissipating heat from the electronic control component 300 more quickly.
[0040] The heat pump 1000 also includes a fan and a compressor. The fan is housed in the casing 100 and located in the fan compartment 111. The fan is responsible for driving airflow and enhancing the heat exchange process, thereby improving the overall efficiency of the heat pump 1000. The compressor is located in the compressor compartment 112. The compressor's main function is to increase the pressure and temperature of the refrigerant, thus promoting heat flow within the system and achieving heating or cooling functions. Of course, the heat pump 1000 may also include other structures, such as an evaporator and an expansion valve, which are not limited here.
[0041] The aforementioned "when the temperature of the electronic control component 300 is lower than the preset temperature, the fan assembly 600 below the electronic control component 300 does not start; when the temperature of the electronic control component 300 is higher than the preset temperature, the fan assembly 600 below the electronic control component 300 starts to accelerate the airflow speed, thereby improving the heat dissipation rate and efficiency" specifically means that in this embodiment, when the temperature of the IPM module (intelligent power module) is <80℃, the small fan 610 under the electronic control motherboard does not start. Only the rotation of the fan blades of the machine fan draws air in from the air inlet 121 of the compressor compartment 112, flows through the ventilation port 500 through the electronic control component 300, and is then discharged through the machine mesh cover. When the IPM module temperature is ≥80℃, the fan assembly 600 under the electronic control component 300 starts. At this time, the operation of the fan blades and the fan assembly 600 draws air in from the air inlet 121 of the compressor compartment 112, through the outlet, flows through the electronic control component 300, and then is discharged through the machine mesh cover, thereby accelerating the airflow speed and dissipating heat more quickly, thus increasing the pass rate of the heat pump 1000 temperature rise test. Of course, the preset temperature value here can be other than 80℃, such as 70℃ or 90℃, depending on the actual working conditions, and is not limited here.
[0042] Please see Figure 1 In this embodiment, the casing 100 on one side of the compressor compartment 112 is provided with louvers 120, and an air inlet 121 is formed at the louvers 120. The airflow into the compressor compartment 112 can be controlled by adjusting the angle of the louvers 120 to achieve energy saving and consumption reduction. Moreover, the design of the louvers 120 makes it difficult for dust and debris to accumulate, and cleaning and maintenance are relatively simple.
[0043] Figure 3 This is a schematic diagram of the removal of the electronic control component 300 provided in an embodiment of the present invention; Figure 4 This is a schematic diagram illustrating the removal of the protective cover 400 as provided in an embodiment of this utility model. Please refer to... Figure 3 and Figure 4 and combined Figure 2To simplify the overall structure and facilitate the installation of the electronic control component 300, the partition 200 in this embodiment has an installation notch 210. The electronic control component 300 is installed at the installation notch 210, and a ventilation opening 500 is formed between the electronic control component 300 and the partition 200 at the installation notch 210. That is, the electronic control component 300 does not completely cover the installation notch 210; the electronic control component 300 is connected to the partition 200, and a portion of the installation notch 210 is exposed to form a ventilation opening 500, so as to deliver air from the compressor compartment 112 to the fan compartment 111. Specifically, the installation notch 210 is provided at the top of the partition 200. Of course, the installation notch 210 can also be provided in the middle or other positions of the partition 200, as long as a ventilation opening 500 is formed between the electronic control component 300 and the partition 200 at the installation notch 210. The location of the installation notch 210 is not limited here.
[0044] Please continue reading. Figure 3 and Figure 4 and combined Figure 2 A mounting gap exists between the electronic control component 300 and the top of the partition 200 to form a vent 500. Positioning the vent 500 at the top helps guide airflow more effectively, promotes air circulation, and avoids localized air stagnation. It also allows for full utilization of the incoming air, increasing the airflow range and thus the heat dissipation area. Furthermore, this arrangement ensures that air passes completely through the electronic control component 300, providing sufficient heat dissipation and improving heat dissipation efficiency. Of course, the electronic control component 300 and the partition 200 can also form vents 500 at other locations within the mounting notch 210; this is not limited to these specific locations.
[0045] Please see Figure 3 In this embodiment, the fan assembly 600 includes a fan 610 and a mounting plate 620, which is connected to the partition 200. The mounting plate 620 has a through hole 621, through which the fan 610 is connected and located. The mounting plate 620 enhances the connection strength between the fan 610 and the partition 200, ensuring connection stability. For ease of installation and maintenance, the fan 610 and mounting plate 620 are detachably connected; and / or, the mounting plate 620 and partition 200 are detachably connected. Specifically, the fan 610 and mounting plate 620 are connected using threaded fasteners, and the mounting plate 620 and partition 200 are also connected using threaded fasteners. These threaded fasteners can be bolts, screws, or other similar structures. Of course, the fan 610 and mounting plate 620 can also be connected using other detachable connection methods such as snap-fit or plug-in, which are not limited here. Mounting plate 620 and partition 200 can also be connected by other detachable connection methods such as snap-fit or plug-in, which are not limited here.
[0046] To further improve the heat dissipation efficiency of the electronic control component 300 and ensure sufficient air contact with the electronic control component 300, please refer to [link / reference needed]. Figure 4 In this embodiment, the electronic control component 300 includes an electronic control board 310 and a heat sink 320. The electronic control board 310 is connected to the partition 200, and the heat sink 320 is disposed on the electronic control board 310. The large-area design of the heat sink 320 increases the contact area with air, thereby accelerating the heat dissipation rate. The effective application of the heat sink 320 can significantly reduce the temperature of the electronic control board 310, thereby preventing overheating damage and maintaining the stability of the electronic control component 300. Specifically, in this embodiment, there are multiple heat sinks 320, which are arranged in parallel and spaced apart. The number of heat sinks 320 is determined according to the actual size of the electronic control board 310 and the heat dissipation efficiency, and is not limited here.
[0047] In this embodiment, multiple heat sinks 320 are arranged parallel to each other and spaced apart along the height direction of the partition 200. The height direction of the partition 200 is the direction of airflow. This arrangement further enhances the heat dissipation effect, creating a convection effect to remove heat from the electronic control component 300 more quickly. Of course, the multiple heat sinks 320 can also be arranged parallel to each other and spaced apart along the width direction of the partition 200; this is not a limitation.
[0048] The working principle of the heat pump 1000 provided in this embodiment is as follows:
[0049] When the heat pump 1000 is operating, air is drawn in through the air inlet 121, enters the compressor compartment 112, and then flows through the vent 500 to the electronic control component 300. After cooling the electronic control component 300, air flows to the fan compartment 111 and is then exhausted. When the temperature of the electronic control component 300 is lower than the preset temperature, the fan assembly 600 below the electronic control component 300 does not start; when the temperature of the electronic control component 300 is higher than the preset temperature, the fan assembly 600 below the electronic control component 300 starts to accelerate the airflow speed, thereby improving the heat dissipation rate and efficiency.
[0050] In summary, the heat pump 1000 includes a housing 100, a partition 200, an electrical control assembly 300, a protective cover 400, and a fan assembly 600. The housing 100 has an installation space 110; the partition 200 is disposed within the housing 100, and the partition 200 divides the installation space 110 into a fan compartment 111 and a compressor compartment 112; wherein, an air inlet 121 is provided on one side of the housing 100 of the compressor compartment 112; the electrical control assembly 300 is disposed within the partition 200, and the fan assembly 600... The control component 300 is located in the fan compartment 111; the protective cover 400 is connected to the partition 200 and is used to cover the control component 300; a vent 500 is formed at the connection between the protective cover 400 and the partition 200, and the vent 500 is used to deliver air from the compressor compartment 112 to the fan compartment 111 after passing through the control component 300; the fan assembly 600 is connected to the partition 200 and is located below the control component 300. By setting the vent 500, air entering the compressor compartment 112 from the air inlet 121 can only enter the fan compartment 111 through the vent 500. Furthermore, by setting the protective cover 400, the air entering the fan compartment 111 can completely pass through the control component 300 before being delivered to the fan compartment 111, which improves the heat dissipation efficiency and rate of the control component 300. By installing a fan assembly 600 below the electronic control component 300, the fan assembly 600 can be activated when the electronic control component 300 is at a high temperature, thereby increasing the airflow speed and dissipating heat from the electronic control component 300 more quickly.
[0051] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
