Description

Technical Field

[0001] The utility model relates to the technical field of cabinet temperature control, and more specifically to a cabinet temperature control device. Background Art

[0002] The cabinet is an indispensable component of electrical equipment and a carrier of electrical control equipment. It is generally made of cold-rolled steel plates or alloys, and can provide waterproof, dustproof, and electromagnetic interference protection for the stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc. When the cabinet is in use, especially in high temperature environments in summer, in order to protect the equipment inside the cabinet, a temperature control device needs to be set to adjust the temperature inside the cabinet in a timely manner, so as to avoid damage to the equipment inside the cabinet caused by high temperature. The traditional cabinet temperature control device is usually composed of a host, an exhaust structure, and a temperature sensor. When the temperature exceeds the set limit, the host will increase the exhaust efficiency, thereby accelerating the air circulation rate inside the cabinet to achieve the effect of rapid heat dissipation, so that the internal temperature of the cabinet is kept within the allowable range, thereby realizing the temperature control inside the cabinet. The application number is "20162057121 3.4” disclosed in the “shielded cabinet temperature control device based on forced air cooling” has solved the problem that there are currently many temperature control methods for shielded cabinets, but there are usually problems such as low heat dissipation efficiency or overly complex heat dissipation component structures. However, in actual use, cabinet temperature control devices with similar structures still have many defects, such as: In the above-mentioned documents, it mainly achieves the effect of heat dissipation and temperature control through air circulation rate, which is OK for low temperature and normal temperature environments such as winter, but if it is in high temperature weather in summer, the cabinet will be relatively high when the cabinet is cooling and cooling, so that the high-temperature air around the cabinet is sucked into the cabinet and then discharged. Although it can speed up the heat dissipation and cooling effect to a certain extent, the effect is not very ideal. It takes a long time to reduce the internal temperature of the cabinet to the allowable range, and the efficiency is low. It is easy to cause damage to the internal equipment of the cabinet due to untimely cooling. In view of this, we propose a cabinet temperature control device. Utility Model Content

When the water source enters the interior of the refrigeration box 9, the refrigeration plate 901 cools the water source to keep the water source in a low temperature state;

[0026] In this embodiment, when the cabinet body 1 is in use, the temperature limit inside the cabinet body 1 is first set through the host 501. When the cabinet body 1 is operating normally, the two groups of heat dissipation structures 3 are controlled to work, one group of heat dissipation structures 3 is for air intake, and the other group of heat dissipation structures 3 is for air outlet. Therefore, when the equipment inside the cabinet body 1 is working, air circulation inside the cabinet body 1 can be achieved, thereby achieving a heat dissipation effect. When the temperature sensor 4 detects that the temperature inside the cabinet body 1 exceeds the limit, the host 501 automatically controls the heat dissipation structure 3 to speed up the speed, increase the air circulation rate, and increase the heat dissipation and cooling effect.

The protective mesh cover 904 is used to protect the second motor 902 and the second fan blade 903;

[0028] In this embodiment, when the water cooling structure is working, because the refrigeration plate 901 will generate high temperature outside when cooling the water source, the bottom of the refrigeration box 9 will be in a high temperature state, which will greatly increase the power consumption and reduce the refrigeration effect. Therefore, the second motor 902 is controlled to work, and the second motor 902 drives the second fan blade 903 to rotate, which can speed up the air circulation rate at the bottom of the refrigeration box 9, and can quickly discharge the heat at the bottom of the refrigeration box 9, thereby ensuring the refrigeration effect, reducing power consumption, and saving energy and being environmentally friendly.
