A MANUFACTURING METHOD OF A HEAT TRANSFER DEVICE WITHOUT POURING TUBE

摘要

A manufacturing method of a heat transfer device without pouring tube includes the following steps: (1) welding the heat transfer device for sealing it, and a slot being left unwelded; (2) pouring the working liquid into the heat transfer device by a thin needle tube through the slot; (3)putting the device into a vacuum conditon, and welding the slot being left quickly. The manufacturing method provides a heat transfer device without pouring tube. The manufacturing process is simplified and the performance and reliability is improved.
