Problems solved by technology

The denser base stations mean higher energy consumption. The power consumption of 5G base stations is 2.5 to 4 times that of 4G base stations. It is mainly generated by AAU and BBU during signal conversion, processing and transmission. The heat increases. If the heat cannot be conducted to the environment and dissipated in time, the internal working temperature of the base station will increase.
Once the rated temperature is exceeded, it will seriously affect the stability of communication, accelerate the aging of components, and even cause equipment failure and paralysis, and even cause fires and other safety accidents due to local high heat
[0003] Generally, room air conditioners are used to transfer heat, dissipate heat, and cool down the overall computer room. Due to its high energy consumption, high noise, and low heat transfer efficiency, it has been unable to meet the heat dissipation and cooling requirements of 5G equipment that has increased power consumption several times compared to the original one. , has been phased out
[0004] The heat pipe heat transfer method that has appeared in recent years is gradually being applied to the heat dissipation of electronic equipment such as communication base stations and data centers. However, the working fluid of heat pipe cooling equipment is R245fa, and its global warming potential (GWP) is 1050. reduce

Embodiment 1

[0053] This implementation examines the deformation of the closed self-circulating heat transfer device after being filled with the working fluid.

[0054] In the temperature range of 0 to 110 °C, the working fluid is filled in the closed self-circulating heat transfer device, and the deformation of the heat transfer device is shown in Table 2 below:

[0055] Table 2 Deformation of heat transfer device

[0056]

[0057]

[0058] It can be seen from Table 2 that when the temperature is not higher than 110 °C, the closed self-circulating heat transfer device is not deformed after filling with each working fluid, which ensures the stable operation of the heat transfer device under various working conditions. Among the working fluids, HFO-1234ze(Z) has the smallest filling amount, which can reduce the use cost.

Embodiment 2

[0060] In this implementation, the heat dissipation and temperature resistance performance and the anti-aging performance of the closed self-circulating heat transfer device were investigated.

Abstract

The invention discloses a closed self-circulation heat transfer device and application thereof. A working fluid of the heat transfer device is selected from one or a mixture of at least two of HFO-1234ze (Z), HFO-1336mz (Z), HFO-1336mz (E), HFO-1224yd (Z), HFO-1233zd (E) or HFO-1233zd (Z). The closed type self-circulation heat transfer device can be used for cooling electronic components, and is particularly suitable for cooling electronic equipment, computers, servers, data centers or communication base stations, and the heat transfer device can maintain the temperature of the heating electronic components to be lower than 90 DEG C at the environment temperature of-40-60 DEG C.

Description

Technical field [0001] The present invention relates to a heat dissipation device, in particular to a heat dissipation device using a product selected from the group consisting of HFO-1234ze(Z), HFO-1336mzz(Z), HFO-1336mzz(E), HFO-1224yd(Z), HFO-1233zd(E) or A closed self-circulation heat transfer device using one or at least two mixtures of HFO-1233zd(Z) as the working fluid. Background technology [0002] In recent years, with the rapid development of the Internet industry, the number of outdoor base stations and data centers has increased dramatically. At present, my country is building a large-scale 5G base station, mainly macro base stations, which mainly include towers, BBU (baseband processing unit), AAU (active antenna unit), optical fiber, base station cabinets, power supply, battery, air conditioner, monitoring equipment, etc. More densely populated base stations mean higher energy consumption. The power consumption of 5G base stations is 2.5 to 4 times that of 4G...
