Evaporator and loop heat pipe

An evaporator that receives heat generated by an electronic device to change at least part of a working fluid from a liquid phase to a gas phase, the evaporator comprising:

• a housing including an accommodation chamber that accommodates the working fluid;
• and
• a heat receiver located on a bottom surface of the housing and thermally connected to the electronic device, wherein
• the housing includes
• a porous plate dividing the accommodation chamber into an upper chamber and a lower chamber and including pores through which the upper and lower chambers communicate with each other,
• at least one working fluid inlet opening into the upper chamber,
• a partition dividing a bottom of the lower chamber into liquid retainers, adjacent liquid retainers being completely separated from each other by portions of the partition in plan view, and
• at least one working fluid outlet opening into the lower chamber and located above the partition.

An evaporator that receives heat from a heat generator to change at least part of a working fluid from a liquid phase to a gas phase, the evaporator comprising:

• a housing including an accommodation chamber that accommodates the working fluid;
• and
• a heat receiver located on a bottom surface of the housing and thermally connected to the heat generator, wherein
• the housing includes
• a porous plate dividing the accommodation chamber into an upper chamber and a lower chamber and including pores through which the upper and lower chambers communicate with each other,
• at least one working fluid inlet opening into the upper chamber,
• a partition dividing a bottom of the lower chamber into liquid retainers, and
• at least one working fluid outlet opening into the lower chamber and located above the partition, the at least one working fluid outlet extending from a top surface of the lower chamber through the upper chamber and penetrating a top surface of the housing.
