Cooling system for semiconductors

DETAILED DESCRIPTION The present invention solves the problems recited in the discussion of the prior art as well as other problems by providing an economical fluid cooling system for semiconductors which is easily powered from a D.
C.
power source.
This system utilizes an oscillating pump to circulate cooling fluid between a semiconductor mounting base, which acts as a semiconductor receptacle, and a fluid reservoir, which acts as a heat exchanger to dissipate the heat generated by the semiconductor and transferred to the cooling fluid.
The oscillating pump is connected to a D.
C.
power source, such as is provided by the battery/ies of an electric vehicle, through a chopper circuit.
This circuit intermittently transmits the D.
C.
power to the pump to power it thereby.
The pump is basically a reciprocating check valve driven by the pump armature acting against a restoring spring.
When the armature is energized the check valve moves fluid through the system and is restored to its original position when the power is terminated.
As such the oscillating pump is ideally suited to be connected to the power battery/ies of an electric vehicle to circulate cooling fluid between the semiconductor mounting base and the heat exchanger reservoir.
The cooling system is easily mounted to the chassis of the electric vehicle.
The reservoir heat exchanger is mounted to a chassis member in a relatively cool area of the vehicle.
The oscillating pump is mounted below the level of the reservoir to insure priming of the pump.
However, it need not be in the same area as the reservoir.
This allows the pump and the chopper circuit to be mounted proximately to the main electrical components to facilitate electrical connection.
In view of the foregoing it will be seen that one aspect of the present invention is to provide a semiconductor cooling system which is driven from a D.
C.
power source.
Another aspect of the present invention is to provide a liquid cooling system for power semiconductors of a battery driven vehicle which system is easily powered by the vehicle battery
