Description

Technical Field

[0001] The invention relates to a cooling device, in particular to a movable cooling device for a control cabinet with a sunshade, and is specifically suitable for a movable cooling device for a control cabinet with a sunshade and strong heat dissipation capability. Background Art

[0002] The electrical cabinet is a cabinet made of steel material used to protect the normal operation of components. The control cabinet can assemble switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in its closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements, so that its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring and transportation industry, etc. There are many wires laid inside the existing electrical control cabinet. During long-term use, the internal heat cannot be dissipated, which affects the efficiency of the electrical control cabinet, so heat must be dissipated through heat dissipation components.

[0003] Existing heat dissipation equipment generally blows cold air from the air inlet at the bottom of the electrical control cabinet to the air outlet at the top of the electrical control cabinet through a heat dissipation fan arranged inside. Although this heat dissipation equipment can exchange heat for various components of the electrical control cabinet through cold air, thereby effectively ensuring the working performance of the electrical appliance and preventing the internal components from being damaged by excessively high temperatures, it still has the following defects:

[0004] 1. Existing electrical control cabinets are generally installed in open-air places. Under the sun in summer, the temperature of the metal shell of the electrical control cabinet is extremely high, which will cause the internal temperature to rise and seriously affect the heat dissipation performance of the electrical control cabinet.

[0005] 2. Extreme weather occurs frequently in Northwest my country, with a huge temperature difference between day and night. During the day, the surface temperature in the Northwest often rises to around 70 degrees Celsius, which increases the heat dissipation requirements for heat dissipation equipment. The heat dissipation capacity of existing heat dissipation equipment cannot meet the demand.

[0006] 3. The heat dissipation equipment is integrated with the electrical control cabinet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The air cooling device in the mobile cooling device of the control cabinet with a sunshade of the present invention is not only equipped with an active rotating shaft, but also equipped with multiple driven rotating shafts. Multiple sets of fan blades are arranged on the active rotating shaft and the driven rotating shaft. When the active rotating shaft and the driven rotating shaft rotate, the air at the bottom of the control cabinet can be blown to the top of the control cabinet through the fan blades to dissipate heat for the control cabinet as a whole. At the same time, the multiple sets of fan blades effectively increase the amount of air passing through the control cabinet, thereby improving the heat dissipation effect. Therefore, the design dissipates heat for the control cabinet as a whole through the air blown out by the fan blades. At the same time, the multiple sets of fan blades increase the amount of air passing through the control cabinet, thereby effectively improving the heat dissipation effect.

[0020] 2. In the mobile cooling device for a control cabinet equipped with a sunshade, a water tank, a water pump and a coil are used to form a water cooling device. The water cooling device can reduce the air temperature through the cooling water in the water tank, so that the temperature of the cooling air generated by the air cooling device is reduced, thereby improving the cooling and heat dissipation effect. Therefore, the design can reduce the air temperature through the water cooling device, effectively improving the cooling and heat dissipation effect of the cooling device.

[0021] 3. The movable cooling device for a control cabinet equipped with a sunshade of the present invention is provided with an arc-shaped cover. The cooling device can block the sunlight through the arc-shaped cover to prevent the sunlight from directly shining on the control cabinet and causing the surface temperature of the control cabinet to rise. At the same time, a motor that can be raised and lowered is provided on the arc-shaped cover. When the motor descends, it meshes with the arc-shaped gear ring provided on the water tank, and the arc-shaped cover moves along the arc-shaped bottom plate and the slide groove provided on the water tank through the force generated between the arc-shaped gear ring and the motor, so that the arc-shaped cover faces the sunlight. Therefore, the design can drive the arc-shaped cover to block the sunlight through the motor, so as to prevent the direct sunlight from reducing the heat dissipation performance of the electrical control cabinet.

[0022] 4. The bottom of a mobile cooling device for a control cabinet with a sunshade of the present invention is provided with a second electric telescopic rod, and the second electric telescopic rod is provided with wheels and a clamping plate. The cooling device can shorten the distance between the clamping plate and the water tank by driving the second electric telescopic rod. After the distance between the clamping plate and the water tank is shortened, the bottom and the bottom of the control cabinet can be clamped respectively, so that the cooling device is firmly fixed on the control cabinet. At the same time, when the control cabinet does not need to dissipate heat, the cooling device can be separated from the control cabinet by extending the second electric telescopic rod. After the cooling device is separated from the control cabinet, it can be moved by the wheels provided thereunder, so that it is convenient to be set on other control cabinets that need to dissipate heat. Therefore, the present design can effectively connect or disconnect the cooling device with the control cabinet by driving the first electric telescopic rod, so that the cooling device can be set on different control cabinets according to the heat dissipation requirements, thereby reducing the number of cooling devices required for multiple control cabinets and effectively reducing the operating cost of the control cabinet.
