Pulsating heat transfer apparatus
First Claim
1. A pulsating heat transfer apparatus, comprising:
- a plurality of separate heat receiving portions, each of which comprising a flat surface for contacting with a heat source, and defining therein at least one first capillary passage;
at least one heat dissipating portion defining therein at least one second capillary passage;
a plurality of capillary pipes connecting the first capillary passages with the at least one second capillary passage to cooperatively form a close-looped, serpentine flow channel having capillary effect; and
vapor slugs and liquid slugs distributed in the flow channel, wherein heat is capable of being transferred from the heat receiving portions to the at least one heat dissipating portion by pulsation of the vapor slugs and liquid slugs.

Abstract
A pulsating heat transfer apparatus includes a number of separate heat receiving portions (100, 200, 300), at least one heat dissipating portion (400), and a plurality of capillary pipes (500). Each heat receiving portion has a flat surface for contacting with a heat source, and defines therein at least one first capillary passage. Each heat dissipating portion defines therein at least one second capillary passage. The first capillary passages, the at least one second capillary passage, together with the capillary pipes form a close-looped, serpentine flow channel having capillary effect. Vapor slugs (600) and liquid slugs (700) are distributed in the flow channel. Heat is capable of being transferred from the heat receiving portions to the at least one heat dissipating portion by pulsation of the vapor slugs and liquid slugs.

10. A pulsating heat transfer apparatus, comprising:
-
at least one heat receiving portion defining therein a plurality of first capillary passages;
at least one heat dissipating portion defining therein a plurality of second capillary passages;
a plurality of capillary pipes connected between the at least one heat receiving portion and the at least one heat dissipating portion to form a flow channel having capillary effect, wherein each of the first capillary passages communicates with two of the second capillary passages via a part of the capillary pipes, and each of the second capillary passages communicates with two of the first capillary passages via another part of the capillary pipes, and wherein the capillary pipes are discrete components prior to being connected to the at least one heat receiving portion and the at least one heat dissipating portion; and
vapor slugs and liquid slugs distributed in the flow channel, wherein pulsation of the vapor slugs and liquid slugs is capable of transferring heat from the at least one heat receiving portion to the at least one heat dissipating portion. - View Dependent Claims (11, 12, 13, 14, 15)
