Method for balancing temperature of outdoor cabinet and structure of outdoor cabinet

Abstract

The invention discloses a method for balancing temperature of an outdoor cabinet and a structure of the outdoor cabinet. The method for balancing the temperature of outdoor cabinet comprises the following steps: assembling the phase-change materials in an outdoor cabinet, and selecting the phase-change materials suitable for the temperature required to run an electronic device in the outdoor cabinet. When the temperature of the environment is lower, the phase-change materials and the electronic device release heat to the environment; when the temperature of the environment is higher, the phase-change materials absorb the heat released by the electronic device to inhibit the temperature in the outdoor cabinet. The outdoor cabinet also adopts the ventilation way of entering from the upper and exiting from the lower to ventilate and dissipate heat externally. The method for balancing temperature of outdoor cabinet and the structure have the advantages of realizing the balance control of the outdoor cabinet temperature by using phase-change materials and passive refrigeration mode, and matching with the ventilation way of entering from the upper and exiting from the lower, thereby protecting the environment and saving the energy; and moreover, the outdoor cabinet has good thermal performance, so that the service life of the electronic device in the outdoor cabinet can be prolonged and the running reliability of the electronic device can be enhanced.

Description

technical field [0001] The invention relates to heat dissipation technology, in particular to a temperature balance method and structure for applying phase change materials to outdoor communication equipment. Background technique [0002] Outdoor cabinets are widely used in communication and other fields. At present, these cabinets can usually meet the basic protection requirements and are used in harsh outdoor environments, but the temperature inside the equipment is difficult to meet the requirements of equipment life and reliability, but the temperature inside the equipment is difficult to control, which seriously affects the effective operation of the equipment life and reliability, increasing operating costs. Statistics show that the reliability of electronic components decreases by 10% for every 2°C increase in temperature; the life at a temperature of 50°C is only 1 / 6 of that at a temperature of 25°C. The ideal operating temperature range of the battery is 20°C to 2...

AI Technical Summary

Problems solved by technology

If ventilation is used to reduce the temperature inside the device, the effect will become very poor when the ambient temperature is relatively high, resulting in a significant shortening of the life of the device

For example: the performance of a battery that was originally used indoors for 5 years has dropped significantly in less than 2 years outdoors, so it has to be replaced and the battery must be repurchased, which also wastes a lot of manpower and material resources for replacement.
