Description

Technical Field

[0001] This utility model relates to the field of heat pipe degassing technology, specifically a high-efficiency heat pipe vacuum water injection degassing device. Background Technology

[0002] A heat pipe is a heat transfer element that fully utilizes the principles of heat conduction and the rapid heat transfer properties of phase change media. Through the heat pipe, the heat of the heated object is quickly transferred to the outside of the heat source. Its thermal conductivity exceeds that of any known metal. A heat pipe vacuum degasser is a device used in industrial electric furnaces, heat treatment equipment and other fields, mainly for testing the power of heat pipe heat exchangers.

[0003] In existing degassing devices, the connection between the heat pipe and the equipment is not tight during use, which can easily lead to leakage, potentially hindering heat transfer and reducing degassing efficiency.

[0004] Based on this, we propose a high-efficiency heat pipe vacuum water injection degassing device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat pipe vacuum water injection degassing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat pipe vacuum water injection degassing device, comprising:

[0026] A groove is formed inside the main pipe, and its size is larger than that of the first shell. When the first shell and the main pipe are closed, the sealing gasket forms a seal between the first shell and the main pipe.

[0027] The opening is located inside the main tube.

[0028] Preferably, the opening size is larger than the size of the liquid outlet needle, that is, the liquid outlet needle can penetrate the groove and deliver the liquid to the main pipe through the groove.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] This high-efficiency heat pipe vacuum water injection and degassing device uses a vacuum pump, a first connecting pipe, and a second connecting pipe to create a vacuum inside the vacuum chamber, and uses a water pump, an inlet pipe, an outlet pipe, and an outlet needle to inject a fixed amount of water into the heat pipe.

[0031] This high-efficiency heat pipe vacuum water injection degassing device uses a combination of a first shell, a sealing gasket, a slot, and an opening.

It includes a vacuum chamber 1 for accommodating the heat pipe to be processed, and a vacuum assembly 200 for evacuating the interior of the vacuum chamber 1. The vacuum assembly 200 includes a vacuum pump 210, such as... Figure 1 As shown, the vacuum pump 210 is fixedly installed on the top of the vacuum chamber 1. The first connecting pipe 220 has a flange at one end installed on the discharge end of the vacuum pump 210, and its free end is connected to the outside. The second connecting pipe 230 has a flange at the other end installed on the feed end of the vacuum pump 210, and its free end is connected to the inside of the vacuum chamber 1.
