Cooling device for machine room

Abstract

The invention discloses a cooling device for a machine room. The cooling device comprises a cooling water channel, a middle water cooling plate, a heat pipe assembly, a frame and a cooling module. The heat pipe assembly comprises a plurality of first heat pipes in a straight rod shape and a plurality of second heat pipes shaped like a Chinese character 'ji', the first heat pipes and the second heat pipes are arranged in a staggered mode, the frame comprises two long frame bodies and two short frame bodies between the two long frame bodies, the two long frame bodies and the two short frame bodies define a rectangular containing space, a row of upper inserting holes and a row of lower inserting holes are formed in each long frame body, the tail ends of the first heat pipes are mounted in the upper inserting holes of the two long frame bodies, the tail ends of the second heat pipes are mounted in the lower inserting holes of the two long frame bodies, the middle water cooling plate and the cooling module are arranged between the heat pipe assembly and one short frame body, mounting grooves are formed in the middles of the bottoms of the two short frame bodies respectively, and a penetrating groove is formed in the bottom of the middle water cooling plate.

Description

technical field [0001] The invention relates to a cooling device for a machine room, in particular to a cooling water channel arrangement for the cooling device for a machine room. 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...

Problems solved by technology

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
