[0002] If the charging pile is overheated, it is necessary to find a way to let it dissipate heat. Compared with other power sources, the heat dissipation of the charging pile system is much larger, and the requirements for the thermal design of the system are extremely strict. There are currently four commonly used cooling modes: natural cooling (mainly Relying on heat sink), forced air cooling, water cooling, air conditioning, due to the influence of volume, cost, reliability and other factors, most companies currently use forced air cooling for processing, so this will inevitably bring Dust, corrosive gas, moisture and other interference

Abstract

The invention discloses a charging pile capable of achieving automatic protection. The charging pile comprises a shell and a heat dissipation device body located in the shell. The heat dissipation device comprises a heat conduction groove, wherein the left end wall of the heat conduction groove is communicated with a heat dissipation groove of which the left side penetrates through the left end surface of the shell; the right side of the heat conduction groove is communicated with a cooling groove; a conversion device is arranged on the right side of the cooling tank; the device can start thefan to dissipate heat when detecting that the heat is too high; meanwhile, when the external temperature rises, the semiconductor is used, and the semiconductor conductivity is increased; when the external temperature is reduced, the characteristic that the semiconductor conductivity is reduced automatically switches the semiconductor, the automatic switching is achieved, the charging efficiency is guaranteed, and the cooling is conducted according to the physical effect of Peltier; meanwhile, the charging current can be detected, the load is prevented from being too large, and circuit protection is conducted.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an automatically protected charging pile. Background technique [0002] If the charging pile is overheated, it is necessary to find a way to let it dissipate heat. Compared with other power sources, the heat dissipation of the charging pile system is much larger, and the requirements for the thermal design of the system are extremely strict. There are currently four commonly used cooling modes: natural cooling (mainly Relying on heat sink), forced air cooling, water cooling, air conditioning, due to the influence of volume, cost, reliability and other factors, most companies currently use forced air cooling for processing, so this will inevitably bring Dust, corrosive gas, moisture and other interference. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a charging pile capable of automatic...
