An electronic device includes first and second housings rotatable relative to each other, a fan inside the housing, and a hinge structure rotatably connecting the first and second housings to each other. The hinge structure includes a vent member rotating together with rotation of the first and second housings. The vent member includes first and second portions which guide first air flow between intake and exhaust openings together with operation of the fan. The first and second housings which face each other define a first angle therebetween, the first and second housings which are maximally rotated define a second angle therebetween, and the first and second housings forming a third angle between the first angle and the second angle, rotates the vent member to dispose the first and second vent portions together guiding air flow in different directions, relative to the front side of the electronic device.

Provided are a flat plate pulsating heat pipe having flexibility and having an improved sealing ability so as not to leak a working fluid therein, and a manufacturing method thereof. The flat plate pulsating heat pipe includes a base part having an upper surface or a lower surface which is plasma-treated, wherein the base part has a plurality of channels formed therein and both end portions of each of the channels are bent and connected to each other to form a closed-loop type or a closed type; and a pair of surface films bonded to an upper portion and a lower portion of the base part and bonded to each other at an outer portion of the base part to seal the channels.

Flexible thermal conductor and manufacturing method thereof

Disclosed are a test chamber and a test apparatus having the same. The test chamber includes a test compartment configured to support a plurality of test boards, each being configured to secure a test object. The test chamber applies a test signal to the test object. The test chamber includes an inlet side and a discharge side, and a supply duct vertically extending along a height of the test compartment. The supply duct supplies the inlet side of the test compartment with the test fluid. The test chamber includes a fluid controller to uniformly control a distribution of a test fluid in the supply duct and uniformly supply the test compartment with the test fluid. The disclosed test chamber and test apparatus provide a uniform test temperature and thereby improve a test reliability of a test object such as a semiconductor or semiconductor package.

Test chamber and test apparatus having the same

Provided is a polymer-based pulsating heat pipe that has high flexibility and is applicable to a flexible electronic device. In addition, by surrounding a channel by a multilayer film including a first blocking layer and coating a bonding part with a second blocking layer in order to prevent air from penetrating through the bonding part between upper and lower films, an inner portion of the channel may be maintained in a vacuum state and heat performance of the polymer-based pulsating heat pipe may be maintained. In addition, although the polymer-based pulsating heat pipe according to the present invention has high flexibility, it is lightweight and has heat performance superior to that of copper, thereby effectively cooling the flexible electronic device.
