Reciprocating-mechanism driven heat loop

Abstract

A heat transfer device which employs a reciprocating mechanism for driving liquid from the heat rejection section to the heat receiving section is disclosed. The heat transfer device is coined as the reciprocating-mechanism driven heat loop which comprises a hollow loop having an interior flow passage, an amount of heat-carrying fluid filled within the loop, and at least one reciprocating driver. The hollow loop has at least one heat receiving section, one heat rejection section, and one liquid reservoir. The reciprocating driver is integrated with the liquid reservoir and facilitates a reciprocating flow of the heat-carrying fluid within the loop, so that the liquid is supplied from the heat rejection section to the heat receiving section under both saturated and unsaturated conditions and a high heat transfer rate from the heat receiving section to the heat rejection section is achieved. A substantial temperature uniformity is also attained when the air is evacuated from the loop and the heat-carrying fluid hermetically sealed within the loop is under a substantially saturated condition. Additionally, many of the heat transfer limitations associated with a heat pipe or capillary pumped loop are essentially eliminated. The embodiments of the reciprocating driver include a solenoid-operated electromagnetic driver and a bellows-type driver employing an external electromagnetic reciprocating mechanism or a mechanical reciprocating mechanism.
