Natural cooling module

Abstract

The invention provides a natural cooling module which comprises a heat pipe heat exchanger I, a heat pipe heat exchanger II, an intermediate heat exchanger, a fan, a frame and an electric control box. A cold side inlet of the intermediate heat exchanger introduces a working medium through a pipeline I, wherein the working medium is cooled by the heat pipe heat exchanger I and the heat pipe heat exchanger II. After absorbing high-temperature return water heat in the intermediate heat exchanger, the working medium evaporates, the working medium flows into the heat pipe heat exchanger I and the heat pipe heat exchanger II through a pipeline II connected with an inlet of the heat pipe heat exchanger I and an inlet of the heat pipe heat exchanger II to be condensed, and high-temperature return water on the heat side is cooled to low-temperature supplied water. Return water of cooling water is cooled directly through a natural cold source via the intermediate heat exchanger, Freon type refrigeration working media are adopted in the heat pipe heat exchanger I and the heat pipe heat exchanger II, the situation that the heat exchangers are subjected to frost cracking in the winter due to the fact that water directly enters the heat exchangers is avoided, and the problem of corrosion generated when water is added into an antifreezing solution to enter the heat exchangers is avoided; and an energy-saving and reliable water supply manner is provided for places with needs for cooling water.

Description

technical field [0001] The invention relates to the field of heat removal in machine rooms, in particular to a natural cooling module. Background technique [0002] The integration density of cabinet servers in the computer room is getting higher and higher, and the heat generated by the server is increasing. In order to ensure that the servers in the computer room with high heat dissipation density work at the most suitable ambient temperature, it is necessary to discharge the continuously generated heat from the computer room in time. Considering the perspective, in order to ensure that the system can maximize the use of natural cold sources in winter, this requires an energy-saving and reliable outdoor cold source supply method. [0003] At present, there are mainly the following ways to use natural cold sources outdoors for heat dissipation in large and medium-sized data centers: [0004] One is to use cooling towers, water pumps, and plate heat exchangers. In winter, t...

Problems solved by technology

This method is more suitable for transitional seasons and areas where the outdoor temperature is relatively low in winter, but the disadvantage is that it consumes a lot of water, and there is a great risk of freezing in winter in severe cold areas, and the addition of ethylene glycol solution has the risk of corrosion to the system pipeline

[0005] The second is to use an air-cooled surface cooler to directly introduce the high-temperature cooling water back into the air-cooled surface cooler, and use the outdoor low-temperature air to reduce the return temperature of the cooling water in the surface cooler, thereby providing the system with Low-temperature water supply, because the water is a closed system, it is suitable for water-scarce areas, but in severe cold areas, it is necessary to solve the problem of antifreeze, if the surface cooler is not used in winter, and the cooling water in it is not drained, it will also cause Surface cooler heat exchange tube freezing cracking problem
