HEAT SPREADER COOLER FOR ELECTRONIC DEVICE

摘要

A heat spreader cooler for an electronic device is provided to prevent an internal wick from being deformed although it is horizontally or vertically installed or installed in the bent state, thereby making the flow of refrigerant smoothly. The refrigerant exists in a casing(5), and the inside of the casing is in the vacuum state. A plurality of wicks(10a,10b) are built along the longitudinal direction of the casing within the casing. A pressure withstanding spacer(20) is arranged between the wicks and is formed in a size corresponding to that of the wicks. A flat type metal plate is inserted into a pin-fin mold and pressed so that protrusions of the pin-fin can be formed at the upper and lower parts thereof. The metal plate is made of the copper or aluminium material.
