FLAT HEAT PIPE
First Claim
1. A flat heat pipe with an evaporator section and a condenser section at opposite ends thereof, the flat heat pipe comprising:
- a hollow flat casing defining a first vapor channel within the evaporator section;
a first wick structure received in the casing at the condenser section, the first wick structure in contact with an inner surface of the casing at the condenser section, the first wick structure comprising at least one contact portion in contact with the inner surface of the casing, and at least one isolated portion isolated from the inner surface of the casing, the at least one isolated portion and the inner surface of the casing cooperatively defining a second vapor channel therebetween, the first and second vapor channels in communication with each other; and
a second wick structure received in the casing at the evaporator section, the second wick structure in contact with an inner surface of the casing at the evaporator section, the second wick structure joining the first wick structure at a joint between the evaporator section and the condenser section.

Abstract
An exemplary flat heat pipe with an evaporator section and a condenser section includes a casing, and a first wick structure and a second wick structure in the casing. The casing defines a first vapor channel within the evaporator section. The first wick structure contacts an inner surface of the casing at the condenser section. The first wick structure includes a contact portion in contact with the inner surface of the casing, and an isolated portion from the inner surface of the casing. The isolated portion and the inner surface of the casing cooperatively define therebetween a second vapor channel in communication with the first vapor channel. The second wick structure contacts the inner surface of the casing at the evaporator section. The second wick structure joins the first wick structure at a joint between the evaporator section and the condenser section.
