Heat exchanger, heat dissipation method for heat exchanger and communication equipment

Abstract

The embodiment of the invention provides a heat exchanger, a heat dissipation method for the heat exchanger and communication equipment. The heat exchanger comprises a first air flue and a second air flue; the first air flue and the second air flue are mutually isolated; the first air flue is provided with a first fan unit and a first group of heat dissipation thin tubes; the second air flue is provided with a second fan unit and a second group of heat dissipation thin tubes; the upper ends of the first group of heat dissipation thin tubes along the gravity direction are communicated with the upper ends of the second group of heat dissipation thin tubes along the gravity direction through steam confluence tubes, and the lower ends of the first group of heat dissipation thin tubes along the gravity direction are communicated with the lower ends of the second group of heat dissipation thin tubes along the gravity direction through liquid confluence tubes; the first group of heat dissipation thin tubes, the steam confluence tubes, the second group of heat dissipation thin tubes and the liquid confluence tubes form a closed pipeline; and heat vaporization liquid is filled in the closed pipeline, radiating fins are arranged between the heat dissipation thin tubes of the first group, and radiating fins are arranged between the heat dissipation thin tubes of the second group. The flow resistance of airflow flowing through the heat dissipation thin tubes is low so as to well meet the heat dissipation requirement of the communication equipment.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat exchanger, a heat dissipation method for the heat exchanger, and communication equipment. Background technique [0002] With the development of communication technology, the integration of communication equipment is getting higher and higher, and the heat consumption per unit space is also increasing. At the same time, in order to meet the needs of the market in the communication field, the application fields of communication equipment are becoming wider and wider. For outdoor communication equipment, the most notable feature is that the communication equipment can adapt to different regional environments, and can also adapt to the temperature of different regional environments. Therefore, outdoor communication equipment should be able to solve the heat dissipation problem of communication equipment in different regions and different environments. [0003] see ...

AI Technical Summary

Problems solved by technology

[0006] The plate heat exchange core 11 in the prior art is composed of partitions, the air outside the communication equipment flows through the second air passage 13 of the plate heat exchange core 11 and the air in the communication equipment flows through the second air duct 13 of the plate heat exchange core 11. When the first air duct is 15, the flow resistance is relatively large. In this way, with the increase of the power of the communication equipment, it may be difficult to meet the heat dissipation requirements of the communication equipment by using the plate heat exchange core.
