This utility model discloses a three-dimensional heat exchanger and controller. The three-dimensional heat exchanger includes a top plate with a first protrusion having a first cavity. A first capillary structure is disposed within the first cavity and communicates with a first receiving cavity of the three-dimensional heat exchanger. After the working fluid in the three-dimensional heat exchanger evaporates in the evaporation zone at the bottom of the heat exchanger, it rises to the top of the first cavity after passing through the first receiving cavity. The vapor diffuses to the condensation zone through the vapor chamber, and the liquid phase flows back through the first capillary structure within the first cavity of the first protrusion. Because the heat exchanger of this application is more three-dimensional due to the first protrusion with a first cavity on the top plate, it can exchange heat in the vertical direction, utilizing more surface area for heat exchange. Furthermore, because the first capillary structure provides a specific channel for vapor to diffuse to the condensation zone, the liquid can also flow back to the evaporation section along a specific path, reducing the resistance to heat transfer. This improves heat exchange efficiency without excessively increasing the volume of the heat exchanger.
