A ventilation and heat dissipation type fiber optic cable distribution box

Abstract

The invention discloses a ventilated and heat-dissipating optical fiber distribution box, which comprises a box body, a heat dissipation plate is lapped on the inner wall of the box body, and a heat dispelling chassis is arranged on the top of the heat dissipation plate, and the inner bottom wall of the heat dispelling chassis is A liquid storage tank is fixedly connected, and the interior of the liquid storage tank is filled with evaporative liquid, the top of the liquid storage tank is connected with a sliding tube, and the inside of the sliding tube is slidably connected with a piston rod, and the sliding tube communicates with the liquid storage tank A pressure valve is installed. This ventilated and heat-dissipating optical cable distribution box will have a large amount of heat accumulation during long-term use. The evaporation liquid in the liquid storage tank is dichloromethane with a boiling point of 39.75 degrees Celsius. When the temperature is high, the evaporating liquid absorbs heat and evaporates. When the temperature is low, the evaporating liquid condenses and liquefies. When the temperature in the cabinet is close to the boiling point of the evaporating liquid, the evaporating liquid quickly absorbs heat and evaporates, initially reducing the temperature in the cabinet, so that the cabinet has a good performance. heat removal effect.

Description

technical field [0001] The invention relates to the technical field of optical fiber distribution boxes, in particular to a ventilation and heat dissipation type optical fiber distribution box. Background technique [0002] The optical fiber distribution box is an interface device used to connect the main optical cable and the distribution optical cable outdoors, in the corridor or indoors. The optical fiber distribution box must be able to work reliably in the specified environment, and the box can withstand a vertical pressure of no more than 500N. ; The multi-core inside it depends on the number of split boxes that can disperse the lines. The more the lines are dispersed, the higher the heat of its own work. [0003] After the existing optical fiber distribution box is installed indoors, it only dissipates heat through some heat dissipation holes, and its heat dissipation effect is not good, which causes the temperature in the box to be too high, resulting in a reduced us...

Problems solved by technology

[0003] After the existing optical fiber distribution box is installed indoors, it only dissipates heat through some cooling holes, and its cooling effect is not good, causing the temperature in the box to be too high, resulting in a reduced use effect; sometimes a cooling fan is installed for cooling, and its The practicability is not strong, and the internal heat dissipation circulation effect is not significant
