Abstract

The invention relates to a heat radiation die set and a radiation system applying a phase change metal thermal interface material. The heat radiation die set and the heat radiation system can ensure that heat generated by the operation of an electronic element can be rapidly transmitted to outside environments. The heat radiation die set comprises a radiator and a phase change metal thermal interface material (TIM), wherein the radiator is arranged above the electronic element, and the bottom surface of the radiator is at least provided with a slot. The phase change metal thermal interface material is arranged between the electronic element and the bottom surface of the radiator, and is used as a thermal interface material between the electronic element and the radiator. When the phase change metal thermal interface material is melted by heating, part of hot melting liquid can flow into the slot so as to prevent the superfluous hot melting liquid from leaking out of a thermal interface.

Description

technical field [0001] The invention relates to a heat dissipation module and a heat dissipation system, in particular to a heat dissipation module and a heat dissipation system using a phase change metal thermal interface foil as a thermal interface material. Background technique [0002] Constructing microelectronic components, such as high-brightness light-emitting diodes and central processing units, etc., due to the development trend towards high power, high speed, and / or miniaturization, the high heat flux generated by microelectronic components must be removed to reduce the junction temperature Maintain below its safe operating temperature. Once the junction temperature of the microelectronic element exceeds the safe operating temperature, the performance of the microelectronic element will be degraded, or the microelectronic element will be damaged, seriously affecting the service life and reliability of the electronic element. [0003] Along with the heat dissipati...
