Description

Technical Field

[0001] The utility model relates to a heat dissipation device, in particular to an auxiliary heat dissipation device for equipment. Background Art

[0002] During the operation of high-power electrical appliances in outdoor cabinets, ventilation with the outside world is generally required to reduce the working temperature of components inside the equipment. Since they are used outdoors, such cabinets usually install ventilation louvers at the air outlet to prevent rainwater intrusion, and the louvers have certain wind resistance and ventilation rate. When no measures are taken between the equipment air outlet and the louvers, part of the heat is discharged from the cabinet through the louvers with the wind, and another part of the heat returns to the inside of the cabinet due to the wind resistance of the louvers, resulting in the accumulation of heat inside the cabinet and being unable to be effectively removed, leading to an increase in the internal temperature of the equipment and affecting the service life and normal operation of the equipment.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] An auxiliary heat dissipation device for equipment, such as Figure 1 As shown in the rear view of a device auxiliary heat dissipation device, it includes a heat dissipation mechanism and an air outlet 4; the front surface of the heat dissipation mechanism is provided with an opening to connect the device shutter, and the rear surface of the heat dissipation mechanism is provided with an air outlet 4; Figure 2 As shown in the side view of an auxiliary heat dissipation device for equipment, the heat dissipation mechanism includes an air collecting shell 1 and a blower mechanism. The rear end face of the air collecting shell 1 is provided with a plurality of blower ports, and the plurality of blower ports are located above the air outlet 4; the blower mechanism is welded inside the air collecting shell 1, and the blower mechanism and the blower port are arranged in one-to-one correspondence; the air collecting shell 1 and the interior of the equipment form an air duct to assist the equipment in dissipating heat.

[0023] Specifically, the air outlet 4 is rectangular, and the area of the air outlet 4 is equal to the area of the device air outlet so that the air outlet 4 is connected to the device air outlet.

[0024] A number of bolts 3 are threadedly connected to the rear end face of the air collecting housing 1 for fixedly connecting the device. The air collecting housing 1 is in the shape of a rectangular box. The material of the air collecting housing 1 is sheet metal. The height of the air collecting housing 1 is greater than the height of the device louver.

[0025] The blowing mechanism includes a fan mounting plate and fans 2; a number of fan fixing holes are provided on the fan mounting plate for mounting a number of fans 2. A number of fans 2 are horizontally arranged on the fan mounting plate. The fans 2 are arranged in one-to-one correspondence with the air blowing ports.

[0026] This embodiment provides the heat dissipation conditions of the device before and after using for a device auxiliary heat dissipation device; a device auxiliary heat dissipation device, including an air collecting housing 1, an air outlet 4 and fans 2; an opening is provided on the front end face of the air collecting housing 1 to communicate with the device louver, an air outlet 4 and four fan ports are provided on the rear end face of the air collecting housing 1, the four fan ports are on the same horizontal line and are all above the air outlet 4; a fan mounting plate is welded inside the air collecting housing 1, a number of fan fixing holes are provided on the fan mounting plate, and the four fans 2 are fixed to the fan mounting plate through the fan fixing holes, and the fan surfaces of the four fans 2 are all located at the fan ports for blowing and heat dissipation.

[0027] A number of bolts 3 are symmetrically arranged on the rear end face of the air collecting housing 1 for fixing the device auxiliary heat dissipation device to the device, and the air outlet 4 is communicated with the device air outlet; the opening on the front end face of the air collecting housing 1 corresponds to the device louver. A air duct is formed between the air collecting housing 1 and the device.

[0028] After the device auxiliary heat dissipation device is installed on the device, as Figure 3 shown in the state diagram of the embodiment of a device auxiliary heat dissipation device without the fan turned on, the hot air generated when the device is working is concentrated inside the air duct through the air outlet 4. Due to the blockage of the four walls of the air duct, the probability of the heat overflowing to other areas inside the device cabinet through air flow is greatly reduced; when the pressure of the hot air concentrated in the air duct increases to a certain extent, under the action of the internal and external pressure difference, the hot air is pressed out of the device through the outlet of the device louver to the external environment of the device.

[0029] After the temperature further rises, the conventional heat dissipation of the device can no longer effectively reduce the internal temperature of the device and when the temperature reaches a certain set value, as Figure 4 shown in the state diagram of the embodiment of a device auxiliary heat dissipation device with the fan 2 turned on, the fan 2 is turned on for heat dissipation; after the fan 2 is turned on, the hot air volume in the air duct inside the air collecting housing 1 is shunted and discharged through the louver in front of the fan 2; the rapid decrease of the air pressure at the device air outlet due to the discharge of more air volume inside the device causes a large amount of external cold air to be pressed into the device through the device air inlet under the atmospheric pressure, thereby increasing the air volume and air speed flowing through the device inside and achieving the effect of assisting the device in heat dissipation.

[0030] The above embodiments are not limitations on the present utility model, nor is the present utility model limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also fall within the protection scope of the present utility model.
