Description

Technical Field

[0001] The utility model belongs to the technical field of charging equipment, and in particular relates to a DC charging power supply cabinet with good heat dissipation performance. Background Art

[0002] There are many types of DC charging power supplies. In the field of new energy charging, large-capacity charging power supplies generally use DC charging power supply cabinets. Multiple power boxes for charging external devices to be charged are stacked inside the DC charging power supply cabinet. The power box draws power through an inverter, and the power box is equipped with a charging power board for determining the size of the load and a cooling fan for dissipating the heat from the charging power board.

[0003] The DC charging power cabinet in the prior art cools down the inside of the cabinet by means of a cooling fan. Since the cabinet body of the power cabinet is a relatively thin single-layer structure, it cannot effectively block external heat. When the temperature difference between the inside and outside of the cabinet is small, the heat dissipation capacity of the cooling fan will be greatly reduced, which may cause the charging power cabinet to malfunction due to increased temperature. Utility Model Content

[0004] The purpose of the utility model is to provide a DC charging power cabinet with good heat dissipation performance. By opening ventilation grooves inside the side walls of the charging cabinet and cooperating with the wind force of a heat dissipation fan to extract the hot air in the ventilation grooves, not only the charging cabinet body can be ventilated and cooled, but also external heat can be blocked and the internal temperature of the cabinet body can be reduced, thereby improving the heat dissipation effect of the heat dissipation fan.

[0007] A grid frame is fixedly connected to the top of the charging cabinet.

[0008] The heat dissipation fan is symmetrically fixedly assembled on the top of the grid frame.

[0009] The inner wall of the ventilation groove and one side of the porous vertical plate is fixedly connected with absorbent cotton.

[0010] A water tank is symmetrically fixedly assembled inside the charging cabinet, and the water tank is fixedly connected to the absorbent cotton through a drip pipe.

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3 As shown, a DC charging power cabinet with good heat dissipation performance includes a charging cabinet 1 and a heat dissipation fan 101. A grid frame 111 is fixedly connected to the top of the charging cabinet 1. The heat dissipation fan 101 is symmetrically fixedly assembled on the top of the grid frame 111. Ventilation grooves 102 are opened inside the side walls of the charging cabinet 1. An air inlet 103 is opened through the bottom of the ventilation groove 102. An air outlet 112 is opened through the top of the ventilation groove 102. Ventilation ducts 104 are fixedly connected in an array inside the charging cabinet 1 and below the heat dissipation fan 101. One end of the ventilation duct 104 is connected to the air outlet 112.

[0020] According to the above structure, the heat dissipation fan 101 is started by electricity. The heat dissipation fan 101 exhausts air from the inside of the charging cabinet 1 through the grid frame 111 to dissipate heat. At the same time, the airflow enters the ventilation clip 102 through the ventilation pipe 104, and the incoming heat is extracted and discharged from the air outlet 112. By utilizing the principle of thermal pressure, the hot air entering from the air inlet 103 is extracted to the top to form a low-pressure area at the top of the rising air flow outlet 112, and the descending air flow forms a high-pressure area at the air inlet 103, forming a pressure difference to cooperate with the exhaust of the heat dissipation fan 101 to push the airflow, and continuously discharge the hot air from the air outlet 112, thereby reducing the heat entering the interior of the charging cabinet 1.

[0021] See attached Figure 2-4 The inside of the ventilation groove 102 is fixedly connected with a porous vertical plate 106, and the two sides of the porous vertical plate 106 are symmetrically fixedly connected with porous horizontal plates 107 at equal distances. The porous vertical plate 106 and the porous horizontal plate 107 are all surrounded by circular holes 110 in an array. The inner wall of the ventilation groove 102 and one side of the porous vertical plate 106 are fixedly connected with absorbent cotton 108. The inside of the charging cabinet 1 is symmetrically fixedly assembled with a water tank 105, and the water tank 105 is fixedly connected to the absorbent cotton 108 through a drip pipe 109.

[0022] According to the above structure, when the circular holes 110 opened by the porous vertical plates 106 and the porous horizontal plates 107 circulate the air flow in the ventilation grooves 102, the air in the circular holes 110 has a certain slow conductivity to heat, which delays the temperature change of the porous vertical plates 106 and the porous horizontal plates 107 themselves, and assists in blocking external heat. When the external temperature is too high, water can be injected into the water tank 105, and the water flows through the drip pipe 109 to soak the absorbent cotton 108, thereby reducing the temperature and humidity inside the ventilation grooves 102 and accelerating heat dissipation. The utility model uses the ventilation grooves 102 opened inside the side walls of the charging cabinet 1 to extract the hot air in the ventilation grooves 102 in cooperation with the wind force of the cooling fan 101, which can not only ventilate and dissipate the cabinet body of the charging cabinet 1, but also block external heat and reduce the internal temperature of the cabinet body, thereby improving the heat dissipation effect of the cooling fan 101.

[0023] The working principle of the utility model is as follows: the heat dissipation fan 101 is started by electricity, and the heat dissipation fan 101 extracts air from the inside of the charging cabinet 1 through the grid frame 111 to dissipate heat. At the same time, the airflow enters the ventilation clip groove 102 through the ventilation pipe 104, and the incoming heat is extracted and discharged from the air outlet 112. By utilizing the thermal pressure principle, the hot air entering from the air inlet 103 is extracted to the top to form a low-pressure area at the top of the rising air flow outlet 112, and the descending air flow forms a high-pressure area at the air inlet 103, forming a pressure difference to cooperate with the exhaust of the heat dissipation fan 101 to push the airflow, and continuously remove the hot air from The air is discharged through the air outlet 112, thereby reducing the heat entering the charging cabinet 1; when the circular holes 110 opened by the porous vertical plates 106 and the porous horizontal plates 107 circulate the air flow in the ventilation slot 102, the air in the circular holes 110 has a certain slow conductivity to the heat, which delays the temperature change of the porous vertical plates 106 and the porous horizontal plates 107 themselves, and assists in blocking the external heat. When the external temperature is too high, water can be injected into the water tank 105, and the water flows through the drip pipe 109 to soak the absorbent cotton 108, thereby reducing the temperature and humidity inside the ventilation slot 102 and accelerating the heat discharge.

[0024] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
