Abstract
The utility model discloses a charger capable of automatically reducing temperature for preventing over-charging. A rectification voltage transformation element is arranged in a charger main body, the exterior of the charger main body is connected with a charging plug by a lead, a fan is arranged in the charger main body, the fan supplies working current by a direct-current output circuit, and heat radiating holes are arranged in a rear cover of the charger. The fan can radiate heat generated by the circuit timely, so that the condition that the charger works under self high temperature can be avoided, and further the service life of the charger can be prolonged.
Description
Technical field
The utility model relates to a kind of electronic component, and it is too high to be specially a kind of temperature that prevents, and can avoid the charger of overshoot.
Background technology
Charger is a kind of equipment that alternating current is converted into low-voltage DC.Along with development of science and technology, storage battery is more and more as the electrical equipment of working power, so the application of charger is also more and more widely.The functional part of present charger is that the electroplax part is arranged in the housing usually, and the heat that produces in the course of work is difficult in time distribute, and the electroplax part is at high temperature worked for a long time and damaged easily.Therefore, present charger is owing to not taking cooling measure to cause its useful life shorter.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of rational in infrastructure that the utility model provides, good heat dissipation effect, the charger of the anti-overshoot of cooling certainly of long service life.
For realizing above-mentioned technical purpose, the utility model is to adopt following technical scheme to realize: a kind of charger from the anti-overshoot of cooling comprises charger body; Be provided with the rectifier transformer element in the charger body; Charger body connects charging plug through lead outward, and it is characterized in that: be provided with a fan in the charger body, fan provides operating current through dc output circuit; Dc output circuit is provided with a current-limiting resistance, and the charger bonnet is provided with louvre.
The utlity model has following beneficial effect: charger when work, the direct current drive work of fan after through conversion, the heat that in time circuit is produced distributes, thereby avoids charger to work down at self high temperature, with the useful life of prolongation charger; On dc output circuit, also be provided with simultaneously a current-limiting resistance, the output current when charging in order to reduce charges with comparatively mild mode, has also slowed down the generation of charger self heat when avoiding damaging storage battery.
