Description

Gas-liquid flow heat exchange unit

This creation is about the heat exchange unit and its heat exchange module, especially a gas-liquid flow heat exchange unit.

By the way, due to the evolution of computing technology, the internal electronic components of various electronic devices or computer equipment will generate a relatively high temperature during operation, and the high temperature is likely to cause damage to the components. Therefore, the heat dissipation mechanism is a very important and necessary design to maintain the normal operation of these electronic components. In addition to general heat dissipation design using fans to provide airflow for convection cooling, or attaching heat dissipation devices of special materials to conduct conduction cooling, water-cooling mechanisms are also an effective and common heat dissipation design. In simple terms, the principle of water-cooled heat dissipation system is generally to use liquid (such as water or coolant) as the heat dissipation medium, and use a continuously operating pump to form a continuous circulation in the water-cooling system. The liquid flows in closed pipes, and these pipes are distributed to the surface of the various electronic components in the system (such as the central processing unit). When the relatively low temperature liquid flows through these relatively high temperature electronic components, it will absorb its heat to slow down its temperature rise. Then, as the pipeline exchanges heat with the outside or other heat dissipation mechanisms to release heat to reduce the temperature of the liquid, the liquid is returned to the system for circulation and heat dissipation. However, the water-cooled heat dissipation system must be equipped with a pump, otherwise it cannot drive the liquid to circulate. Because the pump motor has a certain volume, the internal space of the body of general electronic devices or computer equipment is limited, and it is difficult to install a water-cooled heat dissipation system. In addition, the pump motor will also generate heat during operation, so it is necessary to design the heat dissipation mechanism of the pump motor. Generally, the liquid in the water cooling system is used to dissipate the pump motor. In addition, the water cooling device must be careful to prevent water leakage. , Once water leakage occurs, the internal electronic components of the electronic equipment will be damaged. Therefore, the design and manufacturing costs of water-cooled heat dissipation systems in electronic devices with smaller and smaller internal spaces are getting higher and higher. Solving the above-mentioned problems is the direction that researchers in the field should strive for.

One purpose of this creation is to omit the installation of the motor, reduce the volume of the heat exchange unit and the heat dissipation device for installation in the electronic device, and reduce the design and manufacturing costs. In order to achieve the above objective, the present invention provides a vapor-liquid flow heat exchange unit, which includes: a first cover with a first side, a second side, a steam outlet and a liquid inlet, the steam outlet and The liquid inlet is arranged separately and communicates with the first and second sides; a second cover body has a third side and a fourth side; the first and second cover bodies correspond to the covers and jointly define a heat exchange space with a working Fluid; and a flow dividing unit arranged in the aforementioned heat exchange space and divide the heat exchange space into an evaporation zone and a backwater zone, the evaporation zone corresponds to the steam outlet, and the backwater zone corresponds to the liquid inlet. In order to achieve the above-mentioned purpose, the present invention additionally provides a vapor-liquid flow heat exchange device, which includes: a vapor-liquid flow heat exchange unit, including: a first cover having a first side, a second side, and a A steam outlet and a liquid inlet, the steam outlet and the liquid inlet are arranged separately and communicate with the first and second sides; a second cover has a third side and a fourth side, the first and second covers correspond to The cover merges and jointly defines a heat exchange space, the heat exchange space is provided with a working fluid and a branch unit, and the heat exchange space is divided into an evaporation zone and a return water zone by the branch unit, and the evaporation zone is opposite to Should the steam outlet, the backwater area corresponds to the liquid inlet; and a heat dissipation device with a heat dissipation device outlet and a heat dissipation device inlet, connected to the steam outlet and the heat dissipation device inlet through a first pipe body, through a second pipe The body communicates with the liquid inlet and the outlet of the heat sink.

The flow dividing unit 13 is arranged in the aforementioned heat exchange space 16 and divides the heat exchange space 16 into an evaporation zone 161 and a return water zone 162. The evaporation zone 161 corresponds to the steam outlet 113, and the return water Zone 162 corresponds to the liquid inlet 114. The working fluid 17 flows out from the vapor outlet 113 after the evaporation zone 161 evaporates. The working fluid 17 is condensed from the outside and then flows into the backwater zone 162 from the liquid inlet 114, and causes The working fluid 17 flows back from the water return zone 162 to the evaporation zone 161.

With this design, after the working fluid 17 in the evaporation zone 161 is heated and evaporated (the hollow arrow in Figure 3), the first cover 11 has the effect of accumulating steam, because the working fluid 17 after evaporation will have a higher pressure It is pushed in a small position, so the evaporated working fluid 17 will be pushed to the outlet chamber 143 of the first joint 14 and flowed out from the first outlet 141. On the contrary, the condensed working fluid 17 is subjected to the evaporated working fluid 17 is continuously pushed, it will flow into the water collection chamber 153 from the second inlet 152 of the second joint 15 and into the backwater area 162, so it can still drive the working fluid to drive and circulate without a motor.
