Background

With the development of new energy industry, the power of the related electrical cabinet is larger and larger, and the power density requirement is higher and higher. A large amount of heat needs to be treated, and the traditional heat dissipation mode is to exchange heat inside and outside the cabinet through a fan. The high-power high-density electrical cabinet is concentrated in heating, large in heat quantity, slow in heat dissipation and low in efficiency in the traditional heat dissipation mode, and the heat dissipation requirement of the high-power electrical cabinet is hardly met.

At present, the application environment of new energy equipment is more and more complex, and correspondingly, the protection and sealing requirements on an electric cabinet are higher and higher.

Most of the electrical cabinets in the industry are heat dissipation circulation, long in air duct and poor in heat dissipation effect. The local heat of the device is concentrated, heat is required to be dissipated through a heat exchanger with larger heat exchange capacity, the heat exchange efficiency is low, and the cost is increased.

The above components are each described in further detail below.

As shown in fig. 1, the cabinet 100 is generally rectangular and is mainly used for mounting heat concentration and/or heat sensitive devices. In order to ensure the protection requirements of the electrical cabinet, a high tightness of the cabinet body 100 is required. The cabinet 100 also includes an external interface assembly 170 and an access cable 180. The external interface assembly 170 specifically includes a water outlet 171 and a water inlet 172. The water outlet 171, the water inlet 172 and the periphery of the inlet and outlet cable 180 are sealed by sealing elements, so that the internal environment of the whole electric cabinet is improved, and the reliability and the service life of the whole product are improved.

As shown in fig. 2, the first air duct 130 and the second air duct 140 are disposed in the cabinet 100 independently of each other. In one embodiment of the present application, the space within the cabinet 100 is partitioned into the first air duct 130 and the second air duct 140, which are independent of each other, by a partition (not numbered in the figure). The first air duct 130 and the second air duct 140 are stacked in a vertical direction, for example, the first air duct 130 is disposed above the second air duct 140. Of course, it is understood that the first air duct 130 is also disposed below the second air duct 140; or the first air duct 130 and the second air duct 140 are arranged side by side.

The primary heat source of the high power electrical cabinet includes a first heat source assembly 110 and a second heat source assembly 120. The first and second

heat source assemblies

110 and 120 are installed in the first and

second air ducts

130 and 140, respectively.

The first heat source component 110 specifically includes a user side wiring copper bar 111 and a first filter capacitor 112. In one embodiment of the present application, the user side wiring copper bar 111 is disposed above the first filter capacitor 112. It is understood that in other embodiments of the present application, the user side wiring copper bar 111 is also disposed below the first filter capacitor 112.

The second heat source component 120 specifically includes a grid-connected switch 121, a second filter capacitor 122, and a customer grid-side wiring copper bar 123. The second filter capacitor 122 is disposed below the first filter capacitor 112, the grid-connected switch 121 and the second filter capacitor 122 are disposed in parallel, and the subscriber grid-side wiring copper bar 123 is disposed below the grid-connected switch 121. It is understood that in other embodiments of the present application, the positions of the grid-connected switch 121, the second filter capacitor 122, and the customer grid-side wiring copper bar 123 may also be exchanged.

The first filter capacitor 112, the second filter capacitor 122 and the grid-connected switch 121 belong to heat-sensitive devices, and the temperature of the corresponding connection copper bars needs to be controlled, otherwise, the temperature of the corresponding connection copper bars is transmitted to the heat-sensitive devices through heat conduction and radiation.

The first air duct 130 and the second air duct 140 are also respectively provided with a first gas-liquid heat exchanger 150 and a second gas-liquid heat exchanger 160. The first gas-liquid heat exchanger 150 and the second gas-liquid heat exchanger 160 are arranged to adjust the flow rate relatively independently. In one embodiment of the present application, the first gas-liquid heat exchanger 150 is installed at the upper half of the first air duct 130, and the second gas-liquid heat exchanger 160 is installed at the upper half of the second air duct 140.

As shown in fig. 2, the user side wiring copper bar 111, the first filter capacitor 112 and the first gas-liquid heat exchanger 150 are installed in the first air duct 130, and the user side wiring copper bar 111, the first filter capacitor 112 and the first gas-liquid heat exchanger 150 are connected together end to end in sequence. The cold air blown out from the first gas-liquid heat exchanger 150 passes through the copper bar 111 of the user side wiring and the first filter capacitor 112 in sequence, the cold air absorbs heat to be changed into hot air, then the heat is exchanged to cooling liquid, the cooling liquid brings the heat out, and then the cooling liquid returns to the first gas-liquid heat exchanger 150 for cooling, and the circulation is repeated.

As shown in fig. 2, the second filter capacitor 122, the subscriber line copper bar 123, the grid-connected switch 121 and the second gas-liquid heat exchanger 160 are installed in the second air duct 140, and the second filter capacitor 122, the subscriber line copper bar 123, the grid-connected switch 121 and the second gas-liquid heat exchanger 160 are sequentially connected together end to end. The cold air blown out from the second gas-liquid heat exchanger 160 passes through the second filter capacitor 122, the user network side wiring copper bar 123 and the grid-connected switch 121 in sequence, absorbs heat to be changed into hot air, then exchanges heat to cooling liquid, brings heat out through the cooling liquid, and returns to the second gas-liquid heat exchanger 160 for cooling, and is circulated and reciprocated.

Most of the electrical cabinets in the industry are heat dissipation circulation and long in air duct; and the device with large heat generation is concentrated in heat, so that the conventional heat dissipation mode has low heat dissipation efficiency. On one hand, the device for heat sensitivity and heat concentration is divided, so that cooling air passes through the heat concentration and heat sensitivity areas to be subjected to independent heat dissipation in a concentrated manner, and a good heat dissipation effect is achieved; on the other hand, the electric cabinet is divided into the first air duct 130 and the second air duct 140 for independent heat dissipation, and the liquid cooling flow can be adjusted in a targeted manner according to the heating value of each part, so that the efficient heat dissipation is performed by utilizing the heat exchanger with high cost performance.

The foregoing is merely exemplary of the present utility model, and many variations may be made in the specific embodiments and application scope of the utility model by those skilled in the art based on the spirit of the utility model, as long as the variations do not depart from the gist of the utility model.
