Abstract: A heat dissipation device for an electronic element includes a first chamber containing a printed circuit board with heating elements, and a second chamber for heat exchange. The second chamber contains a refrigerant injection part and supply part. A heat transfer part between the chambers receives heat from the heating elements and transfers it to the second chamber. A condensing part condenses injected refrigerant. The heat transfer part has evaporation-inducing ribs on its surface exposed to the second chamber, allowing injected liquid refrigerant to be adsorbed and flow downward in a zigzag pattern. This configuration enables efficient heat dissipation through phase changes of the refrigerant as it evaporates and condenses. The device may also include features like specially-shaped condensation ribs, a blower part to improve condensation, and a pressure regulator for the second chamber. This design provides improved heat dissipation performance without increasing device size.
