Abstract
The utility model discloses an electricity fetching circuit of a battery charger cooling fan. The circuit comprises an electricity fetching resistor and a power panel, wherein the electricity fetching resistor is connected with the voltage input end of the power panel, and a cooling fan is connected with the output end of the power panel. The circuit is characterized in that the electricity fetching resistance is connected in series with the output loop of a battery charger and arranged on the front side of a shunt. By controlling the output power of the cooling fan through a charging current, the circuit can ensure the cooling wind output of the cooling fan is matched with the heat emission of the battery charger, thereby prolonging the service life of the battery charger, and lowering the energy consumption.
Description
Technical field
The utility model relates to the charger technical field, particularly a kind of power-supply circuit of charger cooling fan.
Background technique
At present, during charger work, the direct current cooling fan on the charger all is to work under the operating voltage of 12V, and fan is in a kind of working state that runs up all the time.This working method, owing to be not to control the discharge quantity of fan of cooling fan according to the relation of charging current and heating value, thereby cause on the one hand: running up of fan, shortened the working life of fan, increased the rate of fault of charger; On the other hand: the cooling air quantity affluence, cause the waste of the energy.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of power-supply circuit that can regulate the charger cooling fan of cooling fan output power with the size of charging current at any time, to solve the existing existing many deficiencys of charger cooling fan way to take power.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of power-supply circuit of charger cooling fan, comprise power taking resistance and power panel, power taking resistance is connected in the voltage input end of described power panel, cooling fan is connected on the output terminal of described power panel, it is characterized in that described power taking resistance string is coupled in the output loop of charger and is positioned at the front side of shunt.
Owing to adopted technological scheme as above, the utility model can be controlled the output power of cooling fan by charging current, the output cooling air quantity of cooling fan and the heat radiation of charger are complementary, have both improved the working life of charger, reduced energy consumption again.
Description of drawings
