Cooling device for computer room with adjustable cooling power

Abstract

The invention discloses a computer room heat dissipation device with an adjustable heat dissipation power. The computer room heat dissipation device with the adjustable heat dissipation power comprises a cooling water channel, a middle water cooling plate, a heat pipe assembly, a frame and a heat dissipation module. The computer room heat dissipation device with the adjustable heat dissipation power is characterized in that the heat pipe assembly comprises a plurality of first heat pipes which are of a straight rod shape and a plurality of second heat pipes which are approximately of an n shape, the heat dissipation module comprises a first heat dissipation module body and a second heat dissipation module body, the middle water cooling plate is located between the first heat dissipation module body and the second heat dissipation module body, and the first heat dissipation module body and the second heat dissipation module body are respectively formed by stacking a plurality of cooling fins. Due to the fact that the heat dissipation module is composed of the first heat dissipation module body and the second heat dissipation module body, the heat dissipation power can be adjusted.

Description

technical field [0001] The invention relates to a cooling device for a computer room with adjustable cooling power, in particular to the setting of its cooling module. Background technique [0002] At present, all IT cabinets and electrical cabinets need heat dissipation. Due to the difference in the heat generated by heat sources, cabinets with low power generation only need to discharge the heat inside the cabinet to the outside of the equipment, and then cool the air through the air conditioner outside the cabinet. Reach the ambient temperature required for the normal operation of electronic devices in the cabinet. However, as the internal heat generation of IT cabinets and electrical cabinets is increasing, the above-mentioned methods can no longer meet the needs of the cabinets to work at normal ambient temperatures. Therefore, the following five cooling methods have been developed: 1. High-power air conditioners accurately control the cabinets. Air supply, the cold ai...

However, as the internal heat generation of IT cabinets and electrical cabinets is increasing, the above-mentioned methods can no longer meet the needs of the cabinets to work at normal ambient temperatures. Therefore, the following five cooling methods have been developed: 1. High-power air conditioners accurately control the cabinets. Air supply, the cold air is forced into the vicinity of the equipment, and the cold air is passively sucked into the cabinet; 2. The cooling redundancy of the working space of the cabinet is greatly increased to ensure a reasonable ambient temperature; 3. On the cabinet Install refrigeration equipment to directly cool the hot air in the cabinet; 4. Install an independent air duct on the cabinet to guide the hot air to the outside for water cooling, and then send the cooled air into the room; 5. Put the cabinet outside the working space The cooling water source is directly connected to the heat exchanger of the cabinet to exchange heat with the hot air

[0003] The corresponding defects of the above five cooling methods are as follows: 1. When the precise air supply method is adopted, the utilization efficiency of the air conditioner is still very low, and a large amount of cold air cannot be used effectively, which makes the cooling efficiency of the air conditioner low. Different time periods still cannot completely avoid the occurrence of local "heat island" phenomenon; 2. Greatly increase the cooling redundancy, which brings a lot of energy consumption and greatly increases the operating cost of the cabinet; 3. Install directly on the cabinet Refrigeration equipment brings a large increase in initial investment and hidden dangers to the reliability and safety of equipment operation; 4. The installation of independent air ducts and then the air-water heat exchange brings about the construction of complex air ducts inside the equipment working space. In most cases, such construction is not allowed in the equipment working space; 5. The cooling water is directly connected to the heat exchanger of the cabinet. The cooling water pipe needs to be as close as possible to the core components inside the equipment cabinet, and the external high pressure If the cooling water leaks, it will cause immeasurable losses to the normal operation of the equipment, and at the same time, it will inevitably produce condensed water, which needs to be treated perfectly

According to the above analysis of the existing cooling technology, various cooling methods will have obvious technical defects under certain circumstances
