Abstract

The invention discloses a heat transfer system driven by piezoelectricity and applied to a self-priming liquid heat exchanger and a heat transfer method of the heat transfer system driven by the piezoelectricity and applied to the self-priming liquid heat exchanger. The heat transfer system driven by the piezoelectricity and applied to the self-priming liquid heat exchanger comprises the self-priming liquid heat exchanger (1), an alternating-current power source (3), a heat source pipeline (6), one-way valves (7), a cold source pipeline (13) and a heat dissipation element (14). The self-priming liquid heat exchanger (1) comprises a piezoelectric vibration partition plate (2), a heat source heat exchange cavity (8), an enhanced heat transfer structure (9), a heat transfer partition plate (10) and a cold source heat exchange cavity (11). According to the heat transfer method of the heat transfer system driven by the piezoelectricity and applied to the self-priming liquid heat exchanger, the piezoelectric vibration partition plate (2) generates periodic vibration under the action of the alternative-current power source (3) to change the volumes of the heat source heat exchange cavity (8) and the cold source heat exchange cavity (11), and a working medium conducts directional circular flow to conduct heat exchange under the blockage function of the one-way valves (7) and the function of periodic vibration. By the adoption of the heat transfer system driven by the piezoelectricity and applied to the self-priming liquid heat exchanger, a liquid drive device in the heat transfer system is simplified, the heat exchange efficiency is improved, and the heat dissipation requirement of a tiny electronic element in a limited space is met.

Description

technical field [0001] The invention relates to the field of enhanced heat transfer, in particular to a piezoelectric-driven self-suction liquid heat exchanger heat transfer system and a heat transfer method thereof. Background technique [0002] In a traditional liquid cooling system circuit, the heat exchanger does not have the role of liquid drive. The directional circulation flow of the working medium in the heat source circuit and the cold source circuit is mainly driven by a mechanical pump connected in series in the pipeline. Because the mechanical pump has many shortcomings such as large volume and high working noise, it is not conducive to the miniaturization of the heat dissipation system and restricts the integration of the heat dissipation system. On the other hand, with the continuous improvement of miniaturization and integration of electronic manufacturing technology, the calorific value per unit volume has increased sharply. Taking computer CPU as an example...
