Description

An electrical cabinet suitable for heat dissipation of high-power electronic devices

technical field

The utility model relates to an electric cabinet, in particular to an electric cabinet installed with electric components with different temperature resistance conditions.

Background technique

With the development of high-power power electronic devices, the heat dissipation of high-power devices has become a more important issue, especially when multiple devices are installed in the screen cabinet, and the temperature resistance of each device is different, the device with low temperature resistance Susceptible to overheating, causing damage when its maximum temperature tolerance condition is exceeded, resulting in unreliable system operation. At present, the heat dissipation of traditional high-power devices generally adopts two methods: air cooling and liquid cooling: Among them, air cooling is to install a fan in the place where the panel cabinet is seriously heated to accelerate air circulation, so as to achieve the purpose of heat dissipation. All devices Share an air duct, so that during the heat dissipation process, the heat emitted by the components with severe heat generation will be transferred to the electronic components with low temperature resistance conditions, so that the heat emitted by the electronic components with low temperature resistance conditions will not only be unable to dissipate, but also It will also receive heat from other devices, failing to achieve the purpose of heat dissipation; and when using liquid cooling, its cost is too high, and it is not suitable for cost control.

Utility model content

The purpose of this utility model is to provide an electrical cabinet to meet the heat dissipation of electronic devices with different temperature resistance conditions.

The technical scheme of the utility model is: an electric cabinet, which is provided with a front door and a rear door, and a partition board is vertically arranged between the front and rear doors in the cabinet body, and the partition board divides the cabinet body into front and rear doors. the latter two parts.

The outer edge of the partition is fitted with the inner wall of the cabinet.

Furthermore, due to the relatively large volume of high-power electrical components, and the volume of the control cabinet cannot be increased arbitrarily due to cost control and installation location restrictions, it is necessary to redistribute the internal space of the cabinet to isolate the space for installing high-power electrical appliances. Position, for this reason, the longitudinal section of the partition is Z-shaped, and the partition is composed of an upper straight plate near the top of the cabinet, a lower straight plate near the bottom of the cabinet, and integrally connected with the upper straight plate and the lower straight plate respectively. The slanting plate is formed, and the upper part straight plate or the lower part straight plate of the Z-shaped partition are respectively close to the front door or the back door of the electrical cabinet.

In order to facilitate the installation and fixing of the electrical components, the upper part and the lower part of the partition are respectively arranged parallel to the side walls of the cabinet.

In order to further strengthen the internal heat dissipation of the electrical cabinet and increase the air circulation inside the electrical cabinet, at least two cooling outlets are respectively opened on the top of the electrical cabinet and located on both sides of the partition, and cooling fans are arranged on the cooling outlets.

Furthermore, in order to increase the heat dissipation of high-power electrical components, an air inlet is provided at the lower part of the front door or the rear door of the electrical cabinet.

With the above structure, electronic devices with different temperature-resistant conditions can be placed on both sides of the partition in the electrical cabinet, so that the heat emitted by the high-power electronic devices with serious heat generation will not be transferred to the temperature-resistant cabinet due to the function of the partition. Low-power electronic devices with low heat generation and low temperature conditions make the temperature of small-power electronic devices with low temperature resistance and low heat generation not affected by the heat emitted by high-power electronic devices with severe heat generation, and can dissipate heat outward, improving the The service life of each electronic device.

Detailed ways

As shown in Figure 1, the cabinet body 1 of the electrical cabinet is respectively provided with a front door 10 and a rear door 11, and a dividing plate 4 is vertically arranged in the cabinet body 1, and the dividing plate 4 divides the interior of the cabinet body 1 into a The side and the side near the back door 11 are two parts. For a more reasonable distribution of the interior space of the cabinet body 1, the partition 4 is made into a Z shape, which is composed of a vertically parallel upper part of the straight plate 6 and a lower part of the straight plate 5 and a middle integrated structure. The inclined plate part 7 is formed, and the length of the lower part of the straight plate 5 is greater than that of the upper part of the straight plate 6. Wherein, the upper part of the straight plate 6 of the dividing plate 4 is close to the back door 11, and the lower part of the straight plate 5 of the attendant 4 is close to the front door 10, and four cooling vents 14 as shown in Figure 3 are provided on the top of the cabinet, and the four cooling vents 14 are arranged in the compartment. On both sides of the board 4 , cooling fans 15 are provided in the cooling openings 14 . Generally, low-power electrical components are installed in a small space between the upper straight plate 6 of the partition 4 and the front door 10, and high-power electrical components are installed in a larger space between the lower straight plate 5 of the partition 4 and the rear door 11. Device, in order to strengthen the heat dissipation of high-power electrical equipment, the bottom of back door 11 is also provided with air inlet 12 as shown in Figure 2.

When the cooling fan 15 on the top of the electrical cabinet was in operation, the cooling fan 15 would draw heat from the cabinet body 1 to the outside of the electrical cabinet, and the cold air outside the electrical cabinet would flow to the power electronic devices, which would be separated in the front and rear parts of the cabinet body. An independent convection wind is formed, and due to the function of the fan and the air inlet, the air convection speed in the electrical cabinet is improved, and the cooling effect is improved. The partition prevents the heat emitted by the high-power electronic devices with serious heat generation installed on one side of the partition from flowing to the low-power electronic devices with low temperature resistance installed on the other side of the partition, thereby improving the service life of the electronic devices.
