Detailed Description
The invention is described in detail below with reference to the drawings and the specific embodiments.
A maintenance-free mute charging pile consists of a box body 1, a heat pipe, an inner circulation fan 4, an outer circulation fan 5, a shutter 6 and sound-absorbing cotton 2.
The box body 1 is a cavity box body 1 with a charging module 3 inside. The heat pipe paste is penetrated through the box body 1 and is attached to the side wall of the box body 1, wherein the inner side wall of the evaporation section of the heat pipe paste the box body 1 is opposite to the charging module 3, and the condensation section of the heat pipe is attached to the outer side wall of the box body 1.
A shutter 6 covering the condensing section is arranged at the outer side wall;
at the inner side wall, a dust-proof filter screen 9 covering the evaporation section is provided.
According to the setting position of the charging module 3 in the case 1:
as shown in fig. 1, when the charging module 3 is placed on top of the inside of the case 1, the heat pipe may be a fin loop heat pipe 7.
When the charging module 3 is placed at the bottom of the case 1 as shown in fig. 2, the heat pipe may be a fin gravity heat pipe 8 as shown in fig. 2 or fig. 4.
The condensing section of the heat pipe is guaranteed to be arranged at the top of the outer side wall of the box body 1 and is relatively far away from the ground, geothermal heat and dust, and meanwhile heat convection is facilitated. In the shutter 6 outside the case 1, an external circulation fan 5 composed of an inlet fan and an outlet fan is provided between the fan blades and the condensing section of the shutter 6 to form heat convection of condensation and heat dissipation. The leaf of the shutter 6 has the effects of rain protection and noise reduction.
An internal circulation fan 4 arranged between the evaporation section and the charging module 3 is arranged in the box body 1, and the wind direction is opposite to the evaporation section. Through the internal circulation, the heat in the box body 1 circularly flows and does not stagnate at any position in the box body 1, so that local high temperature is prevented, and the heat absorption efficiency of the evaporation section to the box body 1 is improved. Forced, active heat exchange is achieved by the inner circulation fan 4 in combination with the outer circulation fan 5.
Preferably, the inner side wall of the box body 1 is also provided with sound absorbing cotton 2 so as to reduce noise generated by the charging module 3, the internal circulation fan 4 and the circulation wind resistance.
In the practical use process, the water-based paint can be used,
the heat generated by the charging module 3 during the operation of the charging pile is brought into contact with the hot air by the internal circulation fan 4 with the evaporation section of the fin loop heat pipe 7 (or the fin gravity heat pipe 8). The working medium in the evaporation section absorbs heat and changes phase, heat is transferred to the condensation section, and then the heat is dissipated to the surrounding environment by the forced convection heat exchange through the external circulation fan 5.
The number and arrangement mode of the fin loop heat pipes 7 and the fin gravity heat pipes 8 can be reasonably selected according to the power and the position of the charging module 3, so that targeted heat dissipation is realized, and the heat dissipation energy efficiency is higher. The fins on the heat pipe can be flexibly adjusted according to actual needs.
As shown in fig. 1, a fin loop heat pipe 7 is fitted to the partially covered louver 6.
The bellows type fin gravity assisted heat pipe 8 shown in fig. 2 is adapted to the partially covered louver 6.
The fin loop heat pipe 7 as shown in fig. 3 is adapted to cover the entire outer side wall, and an outer circulation fan 5 and a fan blade of the louver 6 are provided in the condensing section.
The straight tube fin gravity assisted heat pipe 8 shown in fig. 4 is adapted to the partially covered louvers 6.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the invention in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the invention.
