Description

Cold-storage heat dissipation device

Technical Field

The utility model relates to a heat dissipation field, more specifically relates to a cold-storage heat abstractor.

Background

A base station, i.e. a public mobile communication base station, is an interface device for a mobile device to access the internet, and is a form of a radio station, which is a radio transceiver station for information transmission with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. The construction of mobile communication base stations is an important part of the investment of mobile communication operators, and is generally carried out around the factors of coverage, call quality, investment benefit, difficult construction, convenient maintenance and the like. With the development of mobile communication network services towards datamation and packetization, the development trend of mobile communication base stations is also necessarily broadband, large-coverage construction and IP, and heat generated by machinery or other appliances in the working process is transferred in time to avoid influencing the normal operation of the equipment or instruments.

Common base station radiators can be divided into various types such as air cooling, heat pipe radiators, liquid cooling, semiconductor refrigeration, compressor refrigeration and the like according to the heat dissipation mode, and the high temperature is a large enemy of integrated circuits as is well known. The high temperature can not only cause the unstable operation of the system and shorten the service life, but also possibly burn some parts. The heat that causes the high temperature does not come from outside the computer, but inside the computer, or inside the integrated circuit. The radiator is used for absorbing the heat and then radiating the heat into the case or out of the case, so that the temperature of the computer components is ensured to be normal. Most heat sinks absorb heat by contacting the surfaces of heat-generating components, and then transfer the heat to a remote location by various methods, such as air in a chassis, and then the chassis transfers the hot air to the outside of the chassis, thereby dissipating heat from the computer. The types of radiators are very many, and CPUs, display cards, mainboard chip sets, hard disks, cases, power supplies and even optical drives and memories all need radiators, and the different radiators cannot be used in a mixed manner, wherein the radiator of the CPU is the most frequently contacted. According to the way of taking away heat from the heat sink, the heat sink of the computer can be divided into active heat dissipation and passive heat dissipation. The former is commonly an air-cooled heat sink, while the latter is commonly a heat sink. The further subdivision heat dissipation mode can be divided into air cooling, heat pipes, liquid cooling, semiconductor refrigeration and compressor refrigeration, and the heat dissipation mode refers to the main mode of heat dissipation of the radiator. In thermodynamics, heat dissipation is heat transfer, and the heat transfer mode mainly includes three types: thermal conduction, thermal convection and thermal radiation. The transfer of energy, either by itself or when in contact with a substance, is known as thermal conduction, which is one of the most common ways of heat transfer. For example, the way that the heat sink base of the CPU directly contacts with the CPU to remove heat belongs to heat conduction. The 5G base station is a core device of the 5G network, provides wireless coverage, and realizes wireless signal transmission between a wired communication network and a wireless terminal. The architecture and morphology of the base station directly affect how the 5G network is deployed. In the technical standard, the frequency band of 5G is much higher than that of 2G, 3G and 4G networks, and the 5G network mainly works in the frequency band of 3000-5000MHz at present.

Store in the cold-storage room through refrigeration cycle night, the cold volume in phase change heat exchanger and the water-chilling tank can satisfy the demand of the base station maximum heat dissipation capacity daytime, avoids refrigeration cycle to open when daytime the temperature is high, saves power consumption. This is a means for improving the cooling effect and saving power.

When the first cycle and the second cycle are performed, the flow rate is distributed by the flow rate control valve 35 based on the feedback from the first temperature sensor 25 and the second temperature sensor 26. For example, when the temperature of the first temperature sensor 25 is higher than that of the second temperature sensor 26, the flow to the coil on the first 25 side of the temperature sensor is controlled to be large.

In the vapor compression refrigeration, a low-pressure gaseous refrigerant is sucked by a compressor 12 and then discharged as a high-pressure gas, and is cooled in a condenser 11 to be a low-temperature high-pressure liquid, and finally, the low-temperature high-pressure liquid is throttled to enter an evaporator 13 to exchange heat with water in a cold storage chamber 9 and then is vaporized for refrigeration, so that the internal temperature of the cold storage chamber 9 is reduced. Because the air temperature is lower at night, the efficiency of the refrigerating system is higher, and therefore the refrigerating cycle is started only at night to provide cold energy for the interior of the cold storage chamber and store the cold energy in the cold storage chamber. 0: 00 hours, the refrigeration system is started and keeps running at full power, and the current day is 8: the temperature in the 00 or 9-storage cooling chamber reaches 0 ℃, and the vapor compression type refrigerating device stops working.

When the heating component 1 generates low heat at night and the air temperature is lower at night, the shutter 5 is opened, and the air exchanges heat with the heat pipe. The cold energy of the air at night is stored in the silicone oil phase change microcapsule solution of the liquid cooling case 3. When the outside temperature rises on the second day and the amount of heat generation is not large, it may happen that the outdoor temperature sensor 36 monitors that the ambient temperature is higher than the temperature sensed by the temperature sensor at the heat generating component. Under the working condition, the shutters 5 on the four wall surfaces of the air cooling box body 6 need to be completely closed, the fan needs to be closed, and heat exchange between the condensation side of the heat pipe and the environmental fluid is shielded as much as possible. And (4) dissipating heat by using cold energy stored in the silicone oil phase change microcapsule solution.

When the heating component 1 generates low heat at night and the air temperature is lower at night, the shutter 5 is opened, and the air exchanges heat with the heat pipe. The cold energy of the air at night is stored in the silicone oil phase change microcapsule solution of the liquid cooling case 3. Meanwhile, the temperature of the phase change heat exchanger 16 and the cooling water tank 15 is high due to daytime heat exchange. It may happen that the temperature of the third temperature sensor 29 and the fourth temperature sensor 30 is higher than the temperature of the silicone oil phase change microcapsule solution of the liquid-cooled cabinet 3. Under the working condition, the first circulation can be opened, and the cold energy stored in the silicone oil phase change microcapsule solution is utilized to cool the phase change cooling box and the cooling water tank.
