ABSTRACT:
A high-efficiency isothermal heat pipe adapted for use in electronic equipment having a plate-like body with an enclosed inner chamber which has at least a dividing wall extending in the direction from the front end to the rear end of the body, separating the inner chamber into a plurality of zones which are interconnected by channels for the passage of a saturated working fluid filled in the inner chamber under a vacuum state. The dividing wall extends from the upper wall to the lower wall of the body and is integrally formed therewith so that the heat pipe may not distort in shape during the manufacturing process or when in use. The inner walls of the body have a plurality of grooves arranged between the front end and the rear end of the body for producing capillary action to quickly distribute heat.
