Abstract

The present invention discloses a uniform temperature circuit heat pipe device, it includes circuit heat pipe device equipped with evaporator, condenser and temperature-balancing device, the temperature-balancing device is installed on the evaporating end of the circuit heat pipe device evaporator, the inner surface of the temperature-balancing device is coated with metal net, the metal net is embedded with metal plate with vent holes, the upper and lower surfaces of metal plate are equipped with bracing column, the temperature-balancing device is filled with liquid. The invention absorbs the good heat transfer property of prior circuit heat pipes, and increases temperature-balancing device, it can balance and disperse the high heat flow density concentrating point of electronic chip quickly to reduce the surface temperature of chip, so the application of chip can be expanded to the operations in higher accumulating and gathering degree and higher speed. It changes condense mode on the base of combining the temperature-balancing device and the circuit heat pipe device, the temperature control fins and the condensation fins are used in combing mode to improve the flexibility and accuracy of system to the temperature control.

Description

technical field [0001] The invention relates to the field of heat transfer and cooling of electronic devices, in particular to a heat pipe device for a temperature equalizing circuit. Background technique [0002] The loop heat pipe is a new type of two-phase high-efficiency heat transfer device. It uses the capillary force generated by the capillary core in the evaporator to drive the loop to operate, and uses the evaporation and condensation of the working fluid to transfer heat. The case transfers a large amount of heat. [0003] The evaporator of the loop heat pipe is in contact with the heat source, and a high-performance capillary wick (called the first liquid-absorbing wick) is installed inside the evaporator. The compensation chamber is connected to the evaporator, and the two are internally connected through another capillary wick (called the second liquid-absorbing wick). The condensation section is in direct contact with the cold source. The evaporation pipe co...
