Description

Technical Field

[0001] The present application relates to the technical field of heat pumps, and in particular to an electric control box structure and a heat pump device. Background Art

[0002] A heat pump is a highly efficient and energy-saving device that makes full use of low-grade thermal energy. It transfers low-grade thermal energy from a low-temperature heat source to a high-temperature heat source by consuming a small amount of electrical energy or mechanical energy, thereby achieving heating, cooling or hot water supply.

[0003] At present, since a fan is often provided in a heat pump to enhance the heat exchange efficiency of the evaporator and assist the heat dissipation process of the condenser, air flows inside and outside the heat pump. When the heat pump is in an environment with frequent rainfall, the air flow inside and outside the heat pump will cause the electronic components inside the heat pump to be corroded by rainwater.

[0004] Based on such problems, a fully enclosed electric control box is generally used in existing heat pumps, and all electronic components are installed in the electric control box, so that the electronic components are protected by the fully enclosed electric control box.

[0005] However, although the fully enclosed electrical control box can effectively prevent electronic components from being eroded by rain, it also limits the heat dissipation of the electronic components, making it difficult for some high-heat electronic components to dissipate heat in time, and the high-heat electronic components are prone to over-temperature failures or even damage, which can easily lead to failure of the electrical control box and make the heat pump unable to work. Summary of the invention

[0006] The present application provides an electric control box structure and a heat pump device, the purpose of which is to make the electric control box structure take into account both sealing and heat dissipation performance, realize the protection of electronic components by the electric control box structure, and at the same time improve the heat dissipation performance of high-heat-generating electronic components in the electric control box structure, thereby reducing the probability of failure of electronic components in the electric control box structure and ensuring that the heat pump can work stably.

[0007] In the first aspect, the electric control box structure provided by the present application adopts the following technical solution: An electric control box structure comprises a shell, wherein an isolation plate is arranged inside the shell, wherein the isolation plate divides the space inside the shell into a sealed space and a heat dissipation space, wherein the sealed space and the heat dissipation space of the shell are both used for installing electronic components; an air inlet window is provided on a side wall of the shell, and an air outlet window is provided on the other side wall of the shell, wherein the air inlet window and the air outlet window are both connected to the heat dissipation space; an air guide component is arranged outside the shell, wherein the air guide component is located on a side of the shell where the air inlet window is provided, and wherein the air guide component is used for directing airflow into the air inlet window.

[0008] By adopting the above technical solution, the partition plate divides the space inside the shell into mutually independent sealed space and heat dissipation space, and the sealed space and heat dissipation space of the shell are both used to install electronic components. This enables the partitioned installation of electronic components in the shell, wherein electronic components with lower heat generation or lower heat dissipation requirements are concentratedly packaged in the sealed space, while electronic components with higher heat generation or higher heat dissipation requirements are placed in the heat dissipation space.

[0009] Since the sealed space has a high degree of sealing, and based on the coordinated arrangement of the air outlet window, air inlet window and air guide assembly, the heat dissipation space has a good heat dissipation performance. This design can not only effectively prevent rain from corroding the electronic components in the sealed space, and improve the durability and safety of the equipment in a humid and rainy environment, but also make full use of the external airflow to exchange heat with the high-heating components in the heat dissipation space, and reduce the probability of functional degradation of electronic components due to excessive heating and accumulated fatigue, thereby significantly improving the heat dissipation performance of the equipment.

[0010] Therefore, such a design enables the electric control box structure to take into account both sealing and heat dissipation performance, thereby realizing the protection of the electric control box structure for electronic components, and at the same time improving the heat dissipation performance of high-heat-generating electronic components in the electric control box structure, thereby reducing the probability of failure of electronic components in the electric control box structure and ensuring that the heat pump can work stably.

[0011] Optionally, the air guide assembly includes a plurality of air guide plates, wherein the air guide plates are arranged on the side walls of the shell, the plurality of air guide plates are arranged in sequence along the vertical direction, and two adjacent air guide plates are arranged in parallel and spaced apart to form a guide channel, the guide channel is inclined in the vertical direction, and the upper ends of the guide channels are connected to the air intake windows.

[0012] By adopting the above technical solution, a number of wind guide plates are arranged in coordination to form a number of inclined guide channels outside the shell. Due to the formation of a number of guide channels, the airflow can be guided into the heat dissipation space along a predetermined path, thereby improving the heat dissipation efficiency. And because the guide channels are arranged at an angle in the vertical direction, the airflow is automatically guided into the air intake window by the guide channels when passing through the outer surface of the shell, thereby reducing the direct impact of the airflow on the side wall of the shell, avoiding airflow turbulence, and further optimizing the heat dissipation effect.

[0013] Optionally, an air guide cover plate is further provided on the outside of the shell, and an air guide groove is provided on the side of the air guide cover plate facing the shell, and the air guide groove is directly connected to the air inlet window; an air guide port is provided on the lower side of the air guide cover plate, and the air guide port is connected to the air guide groove, and several of the air guide plates are located in the air guide groove, and the lower end of the guide channel is inclined toward the air guide port.

[0014] By adopting the above technical solution, the coordinated arrangement of the air guide groove and the air guide port on the air guide cover plate enables the airflow to be effectively gathered and introduced into the air guide groove. Furthermore, the airflow can be introduced into the lower ends of several guide channels so that the airflow enters the guide channels, thereby improving the airflow introduction efficiency.

[0015] Optionally, it also includes an air intake regulating mechanism, which is located in the heat dissipation space; the air intake regulating mechanism includes an installation frame, which is arranged on the side wall of the shell with the air intake window, and the air intake window is directly connected to the installation frame; a sealing member is arranged in the installation frame, which closes the air intake window, and the sealing member is slidably connected to the installation frame, and a sealing driving member is arranged on the installation frame, the sealing driving member is connected to the sealing member, and the sealing driving member is used to drive the sealing member to open or close the air intake window.

[0016] By adopting the above technical solution, based on the coordinated arrangement of the mounting frame, the seal and the seal driver, the air intake control mechanism can dynamically adjust the air intake volume in the heat dissipation space according to actual needs.

[0017] In rainy weather or high humidity environments, the seal driver drives the seal to reduce or close the opening of the air intake window, thereby effectively preventing high-humidity air from entering the heat dissipation space and reducing the risk of erosion of internal electronic components. At the same time, in non-rainy or low-humidity conditions, the normal heat dissipation needs of electronic components in the heat dissipation space can be guaranteed by opening the air intake window. This flexible control method not only improves the environmental adaptability of the electric control box structure, but also extends the service life of electronic components, ensuring the stable operation of the equipment in complex environments.

[0018] Optionally, the mounting frame is detachably connected to the inner wall of the shell.

[0019] By adopting the above technical solution, the installation frame and the shell are detachably connected, which makes it easy to select and install an air inlet control mechanism according to actual needs. This design improves the adaptability of the electric control box structure.

[0020] Optionally, it also includes a baffle separation mechanism, which is located in the heat dissipation space; the baffle separation mechanism includes a separation box, which is located between the air inlet window and the air outlet window along its own width direction, and the separation box is provided with a separation inlet on one side of its own width direction facing the air inlet window, and a separation outlet on the other side, and the separation inlet is directly connected to the air inlet window; a plurality of baffles are arranged in the separation box, and the thickness direction of the baffles is arranged along the width direction of the separation box, and a plurality of the baffles are arranged in sequence at intervals along their own thickness direction, and an airflow channel is formed between two adjacent baffles, and a plurality of the airflow channels are connected end to end in sequence to form a baffle channel, and the separation inlet, the baffle channel and the separation outlet are connected in sequence.

[0021] By adopting the above technical solution, based on the formation of the separation box and the deflection channel, the deflection separation mechanism can effectively reduce the humidity of the airflow entering the heat dissipation space.

[0022] When the airflow is introduced into the enclosed space from the air inlet window, the airflow will enter the separation box from the separation inlet, and then the airflow will be discharged from the separation outlet after passing through the baffle channel. Since the baffle design in the separation box forms a tortuous baffle channel, when the airflow passes through the baffle channel, the droplets are separated and deposited at the bottom of the separation box due to inertia, thereby reducing the moisture content in the airflow. This not only improves the moisture resistance of the electronic components in the heat dissipation space, but also extends the service life of the electronic components. In addition, the setting of the baffle channel can also increase the flow path of the airflow in the heat dissipation space, which helps to improve the heat dissipation efficiency.

[0023] Optionally, a drawer opening is provided on the shell, the drawer opening is communicated with the heat dissipation space, and the separation box is plugged into and matched with the drawer opening.

[0024] By adopting the above technical solution, the opening of the drawer is convenient for the installation and removal of the separation box, and the baffle separation mechanism can be installed according to the design requirements. With such a design, in a rainy or high humidity environment, the installation of a baffle separation mechanism can effectively separate the droplets in the airflow, reduce the humidity of the air entering the heat dissipation space, thereby reducing the erosion of water on electronic components and increasing the service life of the components. In a dry environment, the baffle separation mechanism can be selected not to be installed to simplify the structure and maintain good heat dissipation performance. This flexibility enables the structure of the electric control box to adapt to the climatic conditions of different regions and enhance the environmental adaptability of the equipment.

[0025] Optionally, the separation box includes a box body and a cover plate, the cover plate is detachably connected to the box body, and the cover plate closes the box body opening; the separation inlet and the separation outlet are both opened on the box body, and a plurality of the baffles are located in the box body; a plurality of installation slots are opened in the box body, and the plurality of the installation slots are spaced in sequence along the width direction of the box body, the baffles are arranged in one-to-one correspondence with the installation slots, and the baffles are plugged into the corresponding installation slots.

[0026] By adopting the above technical solution, the detachable connection design between the box body and the cover plate makes the separation box easy to assemble and maintain, and also easy to disassemble or maintain the baffles inside the box body. Several baffles are flexibly installed by plugging and matching with the installation slots, which makes it easy to adjust the number and position of the baffles by adding or removing some baffles, thereby optimizing the baffle channel according to actual needs and adjusting the separation effect of the baffle channel on droplets. This makes it possible to modify the separation box according to different actual needs, thereby improving the applicability of the separation box.

[0027] In the second aspect, a heat pump device provided in the present application adopts the following technical solution: A heat pump device comprises the above-mentioned electric control box structure.

[0028] By adopting the above technical solution and the above electric control box structure, the possibility of electronic component failure can be reduced and the heat pump can be guaranteed to work stably.

[0029] Optionally, it also includes a heat pump cabinet, which is vertically arranged, with side air inlets on the sides of the heat pump cabinet, and a top air outlet on the top of the heat pump cabinet. A fan is arranged in the heat pump cabinet, and the fan is arranged opposite to the top air outlet; the shell is vertically arranged in the heat pump cabinet, and the air inlet window is arranged opposite to the side air inlet in the horizontal direction.

[0030] By adopting the above technical solution, the heat pump equipment forms an air flow path from bottom to top by opening side air inlets around the heat pump cabinet and top air outlets on the top, and arranging a fan in the heat pump cabinet that is directly opposite to the top air outlet. At the same time, the shell of the electric control cabinet structure is vertically arranged in the heat pump cabinet, and the air inlet window of the shell is arranged horizontally opposite to the side air inlet of the heat pump cabinet. In the process of the air in the heat pump cabinet flowing from the bottom to the top from the outer side of the shell, the air guide component will guide the flowing air into the air inlet window, so as to provide heat dissipation airflow for the electric control cabinet structure. This solution combines the air flow inside the heat pump equipment with the heat dissipation requirements of the electric control cabinet structure. While ensuring the heat dissipation effect of the electric control components, there is no need to add an additional active cooling device, thereby reducing the overall energy consumption and improving the economy and reliability of the system. In addition, this design can also effectively reduce the functional degradation of electronic components caused by overheating and extend the service life of the equipment.

[0031] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application divides the space inside the shell into a sealed space and a heat dissipation space, so that the electric control box structure can take into account both sealing and heat dissipation performance, thereby realizing the protection of the electronic components by the electric control box structure, and at the same time improving the heat dissipation performance of the high-heat-generating electronic components in the electric control box structure, thereby reducing the probability of failure of the electronic components in the electric control box structure and ensuring that the heat pump can work stably.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1 -Attached Fig.11 , further details of this application are given.

[0047] Embodiment 1: An electric control box structure, referring to Figure 1 and Figure 2 , comprising a shell 1, the shell 1 is vertically arranged, an isolation plate 2 is arranged in the shell 1, and the two ends of the isolation plate 2 are respectively connected to the side wall of the shell 1 and the bottom wall of the shell 1, and the isolation plate 2 divides the space in the shell 1 into a sealed space 3 and a heat dissipation space 4, and the sealed space 3 and the heat dissipation space 4 are independent of each other and not connected. An air inlet window 11 is opened on the side wall of the shell 1, and an air outlet window 12 is opened on the bottom wall of the shell 1, and the air inlet window 11 and the air outlet window 12 are both connected to the heat dissipation space 4.

[0048] Due to the setting of the shell 1, the sealed space 3 is closed, which can protect the electronic components in the sealed space 3. Due to the coordinated setting of the air outlet window 12 and the air inlet window 11 on the shell 1, the heat dissipation space 4 and the space outside the shell 1 can exchange air, which allows the electronic components in the heat dissipation space 4 to fully dissipate heat. Based on such functions, electronic components with low heat dissipation requirements are installed in the sealed space 3, and electronic components with high heat dissipation requirements are installed in the heat dissipation space 4. In this embodiment, at least a main board, a driver board, an electric control installation board and wiring terminals are installed in the sealed space 3, and at least a reactor is installed in the heat dissipation space 4.

[0049] Reference Figure 2 In this embodiment, a first threading hole 21 is provided on the isolation plate 2, and the first threading hole 21 connects the sealed space 3 and the heat dissipation space 4. The provision of the first threading hole 21 enables the electronic components in the sealed space 3 and the electronic components in the heat dissipation space 4 to be connected to each other.

[0050] Reference Figure 2 In this embodiment, a plurality of second threading holes 13 are provided on the bottom wall of the housing 1, and the second threading holes 13 are connected to the sealed space 3. The second threading holes 13 are provided so that the electronic components in the sealed space 3 can be connected to the corresponding actuators in the heat pump device.

[0051] Reference Figure 2 In this embodiment, plum blossom-shaped wire sheaths are installed in the first threading hole 21 and the second threading hole 13. The plum blossom-shaped wire sheath improves the sealing performance of the first threading hole 21 and the second threading hole 13 when the cable can pass through, and also improves the sealing performance of the sealed space 3.

[0052] Reference Figure 1 and Figure 2 In this embodiment, the housing 1 includes a mounting box 14, and the air inlet window 11 and the air outlet window 12 are both provided on the mounting box 14. A panel 15 is provided in the thickness direction of the mounting box 14, and the panel 15 is detachably connected to the mounting box 14, and the panel 15 closes the opening of the mounting box 14. The isolation plate 2 is located in the mounting box 14, and one end of the isolation plate 2 along the thickness direction of the mounting box 14 abuts against the inner wall of the mounting box 14, and the other end abuts against the panel 15. Based on the structural setting of the housing 1, after removing the panel 15, the sealing space 3 and the heat dissipation space 4 can be directly opened, so this facilitates the opening and closing of the housing 1, and further facilitates the installation and removal of electronic components in the electric control box structure 100.

[0053] Reference Figure 2 and Figure 3 An air guide component 5 is provided on the side wall of the shell 1 , and the air guide component 5 is located on the side wall of the shell 1 where an air intake window 11 is opened.

[0054] Reference Figure 2 and Figure 3 The wind guide assembly 5 also includes a plurality of wind guide plates 51, which are located in the air inlet window 11. The length direction of the wind guide plates 51 is arranged along the thickness direction of the shell 1. Both ends of the wind guide plates 51 along their own length direction are connected to the inner side wall of the air inlet window 11. The width direction of the wind guide plates 51 is inclined in the vertical direction, and the upper end of the wind guide plates 51 is connected to the inner side wall of the air inlet window 11. The lower end of the wind guide plates 51 extends away from the shell 1 to protrude from the corresponding side wall of the shell 1. The plurality of wind guide plates 51 are arranged in sequence at intervals along the vertical direction, and the plurality of wind guide plates 51 are arranged in parallel, so that a guide channel 52 is formed between two adjacent wind guide plates 51.

[0055] Reference Figure 3 The guide channel 52 is located outside the shell 1, and the guide channel 52 is inclined in the vertical direction. The upper end of the guide channel 52 is connected to the air intake window 11, and the lower end of the guide channel 52 is inclined downward.

[0056] Since the air guide plate 51 is located outside the shell 1 , when the airflow flows outside the shell 1 , the plurality of guide channels 52 will guide the airflow into the heat dissipation space 4 , which can improve the heat dissipation effect.

[0057] Reference Figure 3 In this embodiment, the air guide plate 51 is wavy along its width direction. This makes the air guide channel 52 wavy along the air flow direction, which facilitates the air flow to be introduced into the heat dissipation space 4 and reduces the air flow kinetic energy loss.

[0058] Reference Figure 3 In this embodiment, both ends of the air guide plate 51 in the length direction are provided with closing plates 53, and the closing plates 53 are connected to the corresponding side walls of the housing 1 and the corresponding air guide plate 51. At this time, the two closing plates 53 at both ends of the air guide plate 51 in the length direction close the corresponding guide channel 52 along the length direction of the air guide plate 51. The setting of the closing plates 53 can reduce the overflow of the airflow from both ends of the corresponding guide channel 52 in the length direction, thereby improving the airflow introduction effect of the guide channel 52.

[0059] Reference Figure 3 and Figure 4 The air guide assembly 5 includes an air guide cover plate 54, which is covered on the air inlet window 11 and closes the air outlet window 12. The air guide cover plate 54 is provided with an air guide groove 541 on the side facing the housing 1, and the air guide groove 541 is directly connected with the air inlet window 11. An air guide port 542 is provided on the lower side of the air guide cover plate 54, and the air guide port 542 is connected with the air guide groove 541. A plurality of air guide plates 51 are located in the air guide groove 541, and the air guide plates 51 are spaced apart from the inner wall of the air guide groove 541, and the lower end of the guide channel 52 is inclined toward the air guide port 542.

[0060] The air guide cover plate 54 is provided with air guide grooves 541 and air guide ports 542. When the airflow rises from the bottom of the shell 1, the airflow will be guided into the plurality of guide channels 52 by the air guide ports 542 and the air guide grooves 541, which can further improve the airflow introduction effect.

[0061] Reference Figure 4 , the outer side of the housing 1 is provided with heat dissipation fins 6, and the heat dissipation fins 6 are arranged opposite to the sealed space 3. When the electronic components in the sealed space 3 have heat dissipation requirements, the heat dissipation fins 6 can effectively increase the heat dissipation capacity of the electronic components in the sealed space 3.

[0062] The implementation principle of the embodiment of the present application is: the space inside the housing 1 is divided into a mutually independent heat dissipation space 4 and a sealed space 3, and electronic components with low heat generation or low heat dissipation requirements are concentrated in the sealed space 3 of the housing 1, while electronic components with high heat generation or high heat dissipation requirements are concentrated in the heat dissipation space 4 of the housing 1. At this time, the sealed space 3 protects the corresponding electronic components, while the heat dissipation space 4 meets the heat dissipation requirements of the corresponding electronic components. This enables the electric control box structure 100 to take into account both sealing and heat dissipation performance, reduce the erosion of rainwater on electronic components, and also meet the heat dissipation requirements of electronic components.

[0063] This embodiment also discloses a heat pump device, referring to Figure 5 and Figure 6 , including the above-mentioned electric control box structure 100 and the heat pump cabinet 200, the heat pump cabinet 200 is vertically arranged, and at least a refrigerant, a compressor, a condenser, an expansion valve, an evaporator and a piping mechanism are arranged in the heat pump cabinet 200, a side air inlet 201 is opened on the side of the heat pump cabinet 200, a top air outlet 202 is opened on the top of the heat pump cabinet 200, and a fan 203 is also arranged in the heat pump cabinet 200, and the fan 203 is arranged directly opposite to the top air outlet 202.

[0064] Reference Figure 2 and Figure 6 The electric control box structure 100 is vertically arranged on the inner wall of the heat pump cabinet 200, the fan 203 is located above the electric control box structure 100, and the side air inlet 201 is arranged horizontally opposite to the air inlet window 11 of the electric control box structure 100.

[0065] The implementation principle of the embodiment of the present application is: based on the design of the side air inlet 201 and the top air outlet 202 of the heat pump device, when the fan 203 is working, the heat pump device realizes side air intake, and the air in the heat pump device flows upward, and finally the air is discharged from the top. In this process, based on the setting of the air guide component 5 on the electric control box structure 100, in the process of air flowing from the bottom to the top from the outer side of the shell 1, the air guide component 5 will guide the flowing air into the air inlet window 11, and then the air flows into the heat dissipation space 4, and finally discharged from the air outlet window 12. In this process, the flowing air effectively dissipates the heat of the electronic components in the heat dissipation space 4.

[0066] The electric control box structure 100 is designed based on the air flow law inside the heat pump equipment, so that the air flow inside the heat pump equipment is combined with the heat dissipation demand of the electric control box structure 100, and the heat dissipation of the electric control box structure 100 is achieved while the air flows in the heat pump equipment, thereby reducing the probability of functional degradation of electronic components in the electric control box structure 100 due to excessive heating and accumulated fatigue; at the same time, since there is no need to add additional active cooling devices, this can reduce overall energy consumption and save energy.

[0067] Embodiment 2: An electric control box structure, referring to Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that it also includes an air inlet control mechanism 7, and the air inlet control mechanism 7 is located in the heat dissipation space 4.

[0068] Reference Figure 8 and Fig. 9 The air inlet regulating mechanism 7 includes a mounting frame 71, a sealing member 72 and a sealing driving member 73. The mounting frame 71 is arranged on the inner side wall of the shell 1. The mounting frame 71 is detachably connected to the shell 1. The air inlet window 11 is located in the mounting frame 71. The sealing member 72 is arranged in the mounting frame 71, and the sealing member 72 closes the air inlet window 11. The sealing member 72 is slidably connected to the mounting frame 71 in the vertical direction. The sealing driving member 73 is arranged on the mounting frame 71, and the driving end of the sealing driving member 73 is connected to the sealing member 72. The air inlet regulating mechanism 7 also includes a plurality of temperature sensors and a plurality of humidity sensors. The plurality of temperature sensors and a plurality of humidity sensors are arranged outside the shell 1. In this embodiment, the mounting frame 71 is connected to the side wall of the shell 1 by bolts.

[0069] Based on the coordinated arrangement of the temperature sensor, the humidity sensor and the air inlet control mechanism 7, when a sudden increase in air humidity and a decrease in ambient temperature are detected, it means that it is raining weather at this time, and the air contains droplets or has high humidity, which seriously corrodes the electronic components in the heat dissipation space 4. Under the action of the air inlet control mechanism 7, the air inlet window 11 can be closed or adjusted down, thereby reducing the airflow entering the heat dissipation space 4, thereby protecting the electronic components in the heat dissipation space 4.

[0070] Reference Figure 8 and Fig. 9 In this embodiment, the sealing member 72 includes a pull rod 721 and a sealing cloth 722. The pull rod 721 is located in the installation frame 71. The length direction of the pull rod 721 is arranged along the thickness direction of the shell 1. The pull rod 721 is slidably connected to the installation frame 71 along the vertical direction, and the driving end of the sealing driving member 73 is connected to the pull rod 721. The sealing cloth 722 is located below the pull rod 721. The length direction of the sealing cloth 722 is arranged along the vertical direction. The upper end of the sealing cloth 722 is connected to the pull rod 721, and the lower end of the sealing cloth 722 is connected to the installation frame 71. The sealing cloth 722 seals the air intake window 11.

[0071] The seal 72 is formed by the cooperation between the pull rod 721 and the sealing cloth 722. When the pull rod 721 rises, the sealing cloth 722 gradually unfolds. At this time, the sealing cloth 722 follows the pull rod 721 to gradually reduce the air intake window 11 until the air intake window 11 is completely sealed. On the contrary, when the pull rod 721 falls, the sealing cloth 722 gradually folds. At this time, the sealing cloth 722 follows the pull rod 721 to gradually increase the air intake window 11 until the air intake window 11 is fully opened. This satisfies the function of the seal 72.

[0072] Reference Fig. 9 In this embodiment, the sealing member 72 further includes a plurality of stabilizing rods 723, which are arranged on the sealing cloth 722, and are arranged parallel to and spaced from the pulling rod 721. The plurality of stabilizing rods 723 are arranged in sequence and spaced from each other along the vertical direction, and the stabilizing rods 723 are slidably connected to the mounting frame 71 along the vertical direction. The plurality of stabilizing rods 723 are added to the sealing cloth 722 to fix the sealing cloth 722, thereby ensuring the sealing effect of the sealing cloth 722 on the air intake window 11.

[0073] Reference Fig. 9 In this embodiment, the sealing drive member 73 adopts a micro electric push rod or a rodless linear motor or a compact ball screw module.

[0074] Reference Figure 7 and Figure 8 The electric control box structure 100 also includes a baffle separation mechanism 8 , which is located in the heat dissipation space 4 .

[0075] Reference Figure 8 and Fig.10The baffle separation mechanism 8 includes a separation box 81, the length direction of the separation box 81 is arranged along the vertical direction, and the separation box 81 is located between the air inlet window 11 and the air outlet window 12 along its width direction. The separation box 81 is located on the side of the installation frame 71 away from the air inlet window 11, and a separation inlet 811 is opened on one side of the separation box 81 in the width direction, and a separation outlet 812 is opened on the other side, and the separation inlet 811 is directly connected to the installation frame 71, that is, the separation inlet 811 is directly connected to the air inlet window 11.

[0076] Reference Figure 8 and Fig.10 A baffle assembly 82 is arranged in the separation box 81, and the baffle assembly 82 includes a plurality of baffles 821. The baffles 821 are vertically arranged in the separation box 81, and the thickness direction of the baffles 821 is arranged along the width direction of the separation box 81. The plurality of baffles 821 are arranged in sequence at intervals along their own thickness direction, and an air flow channel 822 is formed between two adjacent baffles 821, and the length direction of the air flow channel 822 is arranged along the vertical direction.

[0077] Reference Figure 8 and Fig.10 The lower end of the baffle plate 821 is spaced apart from the lower side wall of the separation box 81, and the upper end of another adjacent baffle plate 821 is spaced apart from the upper side wall of the separation box 81, which makes the upper and lower ends of the airflow channel 822 between the two adjacent baffle plates 821 connected to the adjacent airflow channel 822, that is, several airflow channels 822 are connected end to end in sequence, so that several airflow channels 822 are connected end to end in sequence to form a baffle channel 823, and one end of the baffle channel 823 is connected to the separation inlet 811, and the other end is connected to the separation outlet 812.

[0078] Based on the coordinated arrangement of the separation box 81 and the deflection assembly 82, the deflection assembly 82 forms a deflection channel 823 in the separation box 81. The deflection channel 823 has a reciprocating and tortuous arrangement, so that after the airflow passes through the mounting frame 71 and enters the separation box 81, the airflow will flow along the deflection channel 823. Under the action of inertia, the droplets in the airflow will be separated, thereby reducing the humidity of the airflow, thereby reducing the erosion of electronic components in the heat dissipation space 4, and increasing the service life of the electronic components in the heat dissipation space 4.

[0079] Reference Figure 8 and Fig.10 In this embodiment, a plurality of water leakage holes 824 are formed through the bottom of the separation box 81, and the plurality of water leakage holes 824 are all connected to the baffle channel 823. Preferably, the water leakage holes 824 are arranged in a one-to-one correspondence with the air flow channels 822, and the water leakage holes 824 are connected to the corresponding air flow channels 822.

[0080] A water leakage hole 824 is provided at the bottom of the separation box 81 , so that the liquid droplets separated in the air flow can flow out from the water leakage hole 824 after being gathered, thereby preventing water from accumulating in the separation box 81 .

[0081] Reference Figure 8 and Fig.10 The separation box 81 includes a box body 813, a separation inlet 811 and a separation outlet 812 are both provided on the box body 813, and a plurality of baffles 821 are also located in the box body 813. The box body 813 is provided with a cover plate 814 on one side facing the panel 15 along its thickness direction, and the cover plate 814 is located in the heat dissipation space 4. The cover plate 814 is detachably connected to the box body 813, and the cover plate 814 closes the opening of the box body 813. In this embodiment, the cover plate 814 is connected to the box body 813 by bolts.

[0082] Reference Figure 8 and Fig.10 The inner wall of the box body 813 is provided with a plurality of installation slots 8131, which are arranged in sequence along the width direction of the box body 813, and the number of the installation slots 8131 is not less than the number of the baffles 821. The installation slots 8131 and the baffles 821 are arranged one by one, and the baffles 821 are plugged and matched with the installation slots 8131.

[0083] Due to the opening of the installation slot 8131, the installation position and the number of the baffles 821 can be adjusted according to the actual situation, so that the separation box 81 can adapt to different usage requirements. Based on the structural design of the installation box 14, after removing the cover plate 814, it is convenient to directly disassemble and assemble the baffles 821, which makes it easy to adjust the separation box 81 according to actual usage needs.

[0084] Reference Figure 8 and Fig.11 The lower side wall of the housing 1 is provided with a drawer opening 16, which is communicated with the heat dissipation space 4, and the separation box 81 is plugged and matched with the drawer opening 16. The separation box 81 is slidably connected with the inner wall of the housing 1 and the inner wall of the drawer opening 16 along its length direction, and the lower end of the separation box 81 is detachably connected with the housing 1. In this embodiment, the separation box 81 is connected with the housing 1 by a connecting member fixed by bolts.

[0085] Since the separation box 81 is plugged into the drawer opening 16 on the housing 1, it is convenient to install and remove the separation box 81, and it is convenient to install the separation box 81. In the case of less rainfall or dry season, the separation box 81 is not needed, so the separation box 81 can be directly removed, and the drawer opening 16 can be sealed by reinstalling the reinforcement plate, which ensures that the electric control box structure 100 can work normally and the heat dissipation performance is not affected.

[0086] The implementation principle of the embodiment of the present application is: an air intake regulating mechanism 7 and a baffle separation mechanism 8 are added to the heat dissipation space 4 of the shell 1. In areas with heavy precipitation or in the rainy season, the air intake regulating mechanism 7 and the baffle separation mechanism 8 cooperate with each other to effectively control the air intake volume in the heat dissipation space 4 and the water content in the airflow, thereby reducing the erosion of electronic components by rainwater and increasing the service life of electronic components while ensuring that the electronic components in the heat dissipation space 4 can dissipate heat normally.

[0087] Furthermore, since the air inlet regulating mechanism 7 and the baffle separation mechanism 8 can work independently, and can also be independently disassembled and assembled, it is possible to select and install the air inlet regulating mechanism 7 and the baffle separation mechanism 8 according to the precipitation conditions and temperature conditions of the actual working environment of the heat pump equipment and the precipitation law and temperature change law of the working environment of the heat pump equipment. This enables the electric control box structure 100 to adapt to a variety of working environments, thereby improving the applicability of the electric control box structure 100.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
