There are many forms of electrical control cabinets, such as control boxes, such as frequency converters, etc.

The specific structure of the electric control cabinet will be mainly described below.

1 to 9, in an embodiment of the present utility model, the electrical control cabinet includes:

a housing 100, the housing 100 has a mounting cavity;

The partition plate 200, the partition plate 200 is arranged along the height direction of the casing 100 to separate the installation cavity into a heating area 111 and a cooling area 121, the heating area 111 is used for the installation of the heating components 112, and the cooling area 121 For the installation of refrigeration components 500;

The separator 200 has a first air outlet 210 and a second air outlet 220 that communicate with the heating zone 111 and the cooling zone 121 , the first air outlet 210 is close to the top of the separator 200 , and the second air outlet 220 Close to the bottom of the partition plate 200 so that a closed gas circulation air channel is formed between the heating area 111 and the cooling area 121 .

Specifically, in this embodiment, the shell 100 may have many forms, which may be a complete box body or a box body formed by splicing and assembling multiple parts. The installation cavity is used to install electrical components and heat dissipation components. The partition 200 is vertically arranged in the installation cavity, and divides the installation cavity into two mutually independent areas, which are the heating area 111 and the cooling area 121 respectively. In the heat-generating area 111, several heat-generating electronic components may be arranged along the vertical direction (height direction). Electronic components may include electronically controlled components, copper bars, main control boards, capacitors, IGBT modules, diode modules, and the like. And their order can be arranged from bottom to top. The cooling element 500 is installed in the cooling area 121 and is used for releasing cold energy to dissipate and cool down the electronic components in the heating area 111 . The refrigeration component 500 can be in many forms, such as a refrigeration heat exchanger communicating with the refrigerant circulation system, or a component refrigerated by a semiconductor, or a component communicated with an external cold source (such as ice), that is, as long as it can be refrigerated The zone 121 provides cooling and can be installed in the components or equipment in the cooling zone 121 .

The cold air can enter the heating zone from the cooling zone 121 through the first air passage 210, and flow from the heating zone back to the cooling zone 121 through the second air passage 220. Of course, in some embodiments, the cold air can also pass through the cooling zone 121. The first air passage 210 enters the cooling zone 121 from the heating zone, and flows from the cooling zone 121 to the heating zone through the second air passage 220 . The description will be given by taking the example that the cold air flows from the cooling zone 121 to the heating zone through the second air outlet 220 at the bottom of the partition plate 200 . After the air exchanges heat with the cooling element 500 in the cooling zone 121 to cool down, it flows to the bottom of the cooling zone 121 and enters the heating zone through the second air outlet 220 . During the process of gas floating, the electronic components in the heating area pass through the heating zone in turn, and exchange heat with the components respectively, thereby cooling the components. The order of the components passing through can be electronically controlled components, copper bars, main control boards, capacitors, IGBT modules, diode modules, etc., that is, the order of cooling can be the above-mentioned order.

The heat cools down, enters the next air cycle, and so on.

In this embodiment, the first air outlet 210 is arranged at the top of the partition plate 200 and the second air outlet 220 is arranged at the bottom of the partition plate 200, so that the cooling zone 121 and the heating zone form a complete gas circulation air duct , Because the gas circulation air duct is straight up and down, and there is no bending, the air can quickly circulate between the cooling zone 121 and the heating zone, ensuring that the air can quickly and efficiently exchange heat with the electronic components, and the cooling element. The device 500 exchanges heat, which is beneficial to improve the cooling efficiency of the electronic components, and is beneficial to the stable operation of the electronic components; in addition, because the air duct system is a closed circulating air duct, the cold air after heat exchange can be as much as possible. It flows to the heating area for heat exchange, which is beneficial to improve the utilization rate of cooling capacity; at the same time, because the gas circulation air duct is a closed air duct system, it is difficult for the outside air to enter it, so that the outside water vapor cannot enter. In the cooling zone 121, continuous cooling causes the water vapor in the air duct system to be continuously condensed, that is, the cooling element 500 continuously dehumidifies and dries the air in the air duct system, thereby preventing the air from heating up. The area 111 forms condensation, which improves the working stability of the electronic components in the heating area 111 .

In some embodiments, in order to improve the smoothness of the air flow in the air duct, on the basis of miniaturization, to increase the space of the heating area, the casing 100 includes a box body 110 and a rear sealing plate 120, and the partition plate 200 It is the back panel of the box body 110 , and the rear sealing panel 120 and the back panel are enclosed to form a cooling zone 121 .

The flange cover is provided on the back plate, and the flange is sealed and connected to the back plate, so that the rear sealing plate 120 is enclosed with the back plate and the flange to form a refrigeration area. 121. In this way, the space in the box body 110 is used for the heating area 111 , which increases the overall space of the heating area 111 , and is beneficial to improve the heat dissipation effect of the heating element 112 in a limited space.

There are many ways of sealingly connecting the back plate and the rear sealing plate 120, and an example is given below for description. The side of the back plate facing the refrigerating zone 121 is provided with a plurality of flange plates 260, and the plurality of flange plates 260 are enclosed to form a flange opening; the edge of the rear sealing plate 120 has a sealing flange, and the rear sealing plate 120 Corresponding to the setting of the flange opening, the sealing flange is fitted and sealed with the flange plate 260 .

A plurality of flange plates 260 are enclosed to form a rectangular flange opening, and the flange opening covers the back plate as much as possible, so that the space of the cooling zone 121 is as large as possible. The flange plates 260 can be installed on the back plate in sequence, or can be assembled on the back plate as a whole after being spliced. The sealing flanging buckle of the rear sealing plate 120 is attached to the outer side of the flange plate 260 , so that the sealing flanging and the flange plate 260 are adhered and sealed and fixed.

On the basis of the above embodiment, in order to further improve the smoothness of the airflow in the air duct, and to adjust the local wind speed in a targeted manner to improve the heat exchange efficiency between the air and the cooling element 500, the electric control cabinet also It includes a capacity expansion plate 130, a part of the rear sealing plate 120 is provided with a ventilation port 126 corresponding to the capacity expansion plate 130, and the capacity expansion plate 130 is sealedly connected with the rear sealing plate 120, so that the expansion plate 130, the rear The sealing plate 120 and the back plate together form the cooling zone 121 .

Specifically, in this embodiment, by opening the ventilation opening 126 and then disposing the expansion board 130 , the space of the cooling zone 121 at the position corresponding to the expansion board 130 can be increased. The position of opening the ventilation port 126 can be set corresponding to the refrigeration component 500 and the airflow driving device, so that the location of the refrigeration component 500 and the location of the airflow driving device have enough space for air flow, and the resistance is small to ensure the fluidity of the air. Since the ventilation openings 126 are partially opened, the space in the refrigeration area 121 is not a flat space, and the space thickness of the refrigeration area 121 corresponding to the expansion plate 130 is greater than that of other locations in the refrigeration area 121 . In this embodiment, the general shape of the expansion plate 130 is an L-shape, and the area corresponding to the L-shaped plate covers the positions of the refrigeration component 500 and the airflow driving component, so that the airflow can flow smoothly therebetween. As for other sections with less thickness, due to the thinner air thickness and greater resistance, the air flow through other positions is smaller than the air flow through the expansion plate 130 , thereby improving the air flow efficiency. Specifically, the refrigerating component 500 includes a refrigerating heat exchanger, and the length direction of the refrigerating heat exchanger is arranged along the width direction of the casing 100 , so that the refrigerating heat exchanger is arranged laterally. The electrical control cabinet includes an airflow driving member 600 , and both the refrigeration heat exchanger and the airflow driving member 600 are disposed corresponding to the ventilation opening 126 .

In order to further improve the efficiency of air flow, the electric control cabinet includes a refrigeration heat exchanger and an air flow driving member 600, the first air passage 210 is close to the top of the partition 200, and the second air passage 220 is close to the At the bottom of the partition plate 200 , the refrigeration heat exchanger is disposed corresponding to the first air passage 210 , and the airflow driving member 600 is disposed corresponding to the second air passage 220 . There are many forms of the airflow driving member 600, taking a fan as an example.

Specifically, in this embodiment, the cooling heat exchanger is arranged at the first air passage 210, and the airflow driving member 600 is correspondingly arranged at the second air passage 220, so that the air at the top of the refrigerating zone 121 and the cooling heat exchanger are connected to each other. For heat exchange, the airflow driving member 600 drives the heat-exchanged cold air to the bottom of the heat-generating area 111, and the cold air flows upward under the action of wind pressure. The components perform heat exchange to cool down the heating components 112 , and the hot air after the heat exchange flows back to the cooling zone 121 through the first air outlet 210 at the top. In this way, the cold airflow passes through the entire heat generating area 111 from bottom to top, and exchanges heat with all the heat generating components 112 , which is beneficial to improve the effect of single air circulation. In the refrigeration zone 121, due to the disposition of the expansion plate 130, the air flow efficiency of part of the air between the refrigeration heat exchanger and the second air outlet 220 is high, thereby greatly improving the air flow efficiency of the entire gas circulation air duct.

In some embodiments, in order to further improve space utilization and air flow efficiency. The refrigerating heat exchanger is arranged in the cooling area 121 , and the airflow driving member 600 is arranged in the heating area 111 . The cooling heat exchanger is arranged at the top of the cooling zone 121 , and the airflow driving member 600 is arranged at the bottom of the heating zone 111 . By arranging the airflow driving member 600 at the bottom of the heat generating area 111, there is no obstruction between the airflow driving member 600 and the preset air supply area, so that the airflow driving member 600 can efficiently extract the cold air from the cooling area 121 and deliver it. to the preset position of the heating area 111 . By arranging the refrigeration heat exchanger at the top, the high temperature gas after heat exchange can efficiently exchange heat with the low temperature heat exchanger. In addition, the refrigerating heat exchanger is arranged in a flat shape, and the first air passage 210 is blocked by its side surface.

In order to realize the gradual reduction of water vapor in the closed gas circulation air duct, the electric control cabinet further includes a water receiving tray 510, and the water receiving tray 510 is arranged directly below the refrigeration heat exchanger; the refrigeration heat exchanger Having a fluid input port and a fluid output port, the width of the water receiving tray 510 corresponding to the positions of the fluid input port and the fluid output port is greater than the width of other positions of the water receiving tray 510 . The water receiving tray 510 receives the condensed water generated during cooling, so that the water vapor in the air duct is reduced. In addition, the condensed water can be output to the electric control cabinet at an appropriate time, so that the condensed water can be completely separated from the air duct. Taking the refrigerant flowing inside the refrigeration heat exchanger as an example, the fluid input port of the refrigeration heat exchanger is connected with a refrigerant inflow pipe for the inflow of the refrigerant, and the fluid output port is connected with a refrigerant output pipe for the outflow of the refrigerant. The temperature is low, so that the temperature of the refrigerant inflow pipe and refrigerant output pipe connected to it is also low, and it is easy to form condensed water. By setting the width of the water receiving tray 510 to be wider, the condensed water formed at the positions of the fluid input port and the fluid output port can be collected. It is beneficial to dehumidify the air duct system.

In order to further dissipate heat to some components in the heat generating area 111 , the electrical control cabinet further includes a module radiator 300, the module radiator 300 has a cooling flow path, and the module radiator 300 is arranged on the partition plate 200 and located in the cooling area 121 , the heat-generating device is disposed on the module heat sink 300 and located in the heat-generating area 111 . The module radiator 300 has a cooling flow path inside, and the cooling liquid takes away the heat of the module radiator 300 when passing through the cooling flow path, thereby reducing the temperature of the module radiator 300 and the heating element 112 . The cooling liquid enters the module radiator 300 through the cooling liquid inlet 320 , and then flows out of the module radiator 300 from the cooling liquid outlet 310 . In this way, the module radiator 300 can dissipate heat both through the internal flow path and through the air duct, which is beneficial to the heat dissipation of the heat-generating components 112 disposed on the heat dissipation module. There may be many heating components 112 that can be disposed on the module heat sink 300 , such as a rectifier and inverter heating module 330 .

In some embodiments, in order to ensure that condensed water does not form on the surface of the heat dissipation module and affect the operation of the heating element 112 , the flow path where the module radiator 300 is located is provided with a flow regulating valve to adjust the flow into the module radiator 300 liquid flow. Through the setting of the flow regulating valve, the amount of cold energy carrier (cooling liquid) entering the module radiator 300 can be controlled, so that the heat dissipation of the module radiator 300 can be controlled, and then the temperature of the module radiator 300 can be controlled. When the temperature of the module radiator 300 is relatively high, the opening of the regulating valve can be increased to increase the amount of coolant entering the module radiator 300 to accelerate heat dissipation. When the temperature of the module radiator 300 is relatively low, the opening of the regulating valve can be reduced. The opening degree reduces the amount of cooling liquid entering the module radiator 300 and slows down the cooling rate to ensure that the temperature of the module radiator 300 is higher than that of other components, thereby ensuring that condensation water will not form on the module radiator 300 .

The bottom plate 700 of the electric control cabinet is provided with a number of wire holes, the wires 720 are connected to the components of the heating area 111 or the cooling area 121, and extend out of the electric control cabinet through the wire holes.
