[0024] See also Figure 1-10 As shown, the utility model relates to a contact angle high-temperature vacuum water-cooled test chamber, comprising a furnace body 1, wherein the furnace body 1 comprises a furnace wall 11, a base 12 and a furnace cap 13, wherein the furnace wall 11 is a cylindrical tube, a base 12 is provided at the bottom of the furnace wall 11, and a detachable furnace cap 13 is provided at the top of the furnace wall 11, wherein the furnace wall 11, the base 12 and the furnace cap 13 are combined to enclose a hollow cavity 14. The furnace wall 11 includes an inner furnace wall 111 and an outer furnace wall 112, a water cooling chamber 113 is provided between the inner furnace wall 111 and the outer furnace wall 112, and four water cooling rings 114 connected to the inner furnace wall 111 and the outer furnace wall 112 are provided in the water cooling chamber 113 as a partition, and the four water cooling rings 114 are evenly and vertically distributed in the water cooling chamber 113 from top to bottom. Furthermore, each of the water cooling rings 114 is provided with a guide opening 115, and the guide openings 115 of the two adjacent water cooling rings 114 are staggered by 180 degrees, such as Figure 5 shown.

[0025] Furthermore, the four water-cooling rings 114 divide the water-cooling chamber 113 into five cold water layers, namely the first cold water layer 1161, the second cold water layer 1162, the third cold water layer 1163, the fourth cold water layer 1164 and the fifth water-cooling layer 1165, which are sequentially distributed in the water-cooling chamber 113 from bottom to top. The outer furnace wall 112 of the furnace body 1 is provided with a water inlet 15 and a water outlet 17, the water inlet 15 passes through the outer furnace wall 112 and is connected to the first cold water layer 1161, and the water inlet 15 is externally connected to the water inlet pipe 16. The water outlet 17 passes through the outer furnace wall 112 and is connected to the fifth cold water layer, and the water outlet 17 is externally connected to the water outlet pipe 18.

[0026] In this embodiment, a pair of first outer pipes 24 and a pair of second outer pipes 32 that penetrate the hollow cavity 14 are provided on the furnace body 1. In this embodiment, the first outer pipe and the second outer pipe 32 are cross-arranged on the furnace body 1 and are both penetrated with the hollow cavity 14. An inner pipe 22 that penetrates the hollow cavity 14 but does not penetrate the hollow cavity 14 is provided in the first outer pipe 24. The first outer pipe 24, the second outer pipe 32, and the hollow cavity 14 constitute an outer vacuum chamber 3, and the inner pipe 22 constitutes an inner vacuum chamber 2. One end of the inner vacuum chamber 2 is provided with an air inlet end 21, and the other end is respectively connected to an inner vacuum gauge 25 and a manual baffle valve 23. The inner vacuum gauge 25 is used to measure the vacuum degree of the inner vacuum chamber 2, and the manual baffle valve 23 is used to control the opening or closing of the inner vacuum chamber 2, so as to realize vacuuming of the inner vacuum chamber 2 by an external vacuum pump. The outer vacuum chamber 3 is connected to an outer vacuum valve 31 and an outer vacuum gauge 33 respectively. The outer vacuum gauge 33 is used to measure the vacuum degree of the outer vacuum chamber 3. The outer vacuum valve 31 is used to control the opening or closing of the outer vacuum chamber 3 so as to realize the vacuum pumping of the outer vacuum chamber 3 by the external vacuum pump.

[0027] The first outer pipe 24, the second outer pipe 32, and the hollow cavity 14 constitute an outer vacuum chamber, the outer vacuum gauge 33 measures the vacuum degree of the outer vacuum chamber, the outer vacuum valve 31 extracts vacuum from the outer vacuum chamber through a vacuum pump, the inner pipe 22 constitutes an inner vacuum chamber, the manual baffle valve 23 extracts vacuum from the inner vacuum chamber through a vacuum pump, and the inner vacuum gauge 25 measures the vacuum degree of the inner vacuum chamber. During the test, the outer vacuum chamber and the inner vacuum chamber are respectively evacuated by the vacuum pump through the outer vacuum valve 31 and the manual baffle valve 23. After the hollow cavity 14 reaches a certain vacuum degree, the outer vacuum chamber stops evacuating, and the inner vacuum chamber continues to evacuate. The inner and outer vacuum chambers are switched to prevent the heat insulation cotton on the inner wall of the hollow cavity 14 from generating impurities during the evacuation process, which affects the test results. Reasonable arrangement of the vacuum pipe makes the vacuum degree data more real and reasonable.

[0028] When the utility model is used for cooling a contact angle high-temperature vacuum water-cooled test cavity by filling water, cooling water flows into the first cold water layer 1161 from the water inlet pipe 16. When the first cold water layer 1161 is filled with cooling water, the cooling water overflows from the guide opening 115 to the second cold water layer 1162. When the second cold water layer 1162 is filled with cooling water, the cooling water overflows from the guide opening 115 to the third cold water layer 1163. This is analogous to the fifth cold water layer. After the cooling water fills the fifth cold water layer, the cooling water is discharged from the water outlet pipe 18.

[0029] The utility model mainly provides four water cooling rings 114 in the water cooling chamber 113 between the inner furnace wall 111 and the outer furnace wall 112 of the furnace body 1, so that the water cooling chamber 113 is divided into five cold water interlayers, and each water cooling ring 114 is provided with a guide opening, and the guide openings 115 of two adjacent water cooling rings 114 are staggered by 180 degrees, so that the cooling water is forced to flow through more distances, thereby increasing the refrigeration area, thereby improving the utilization rate of the cooling water, protecting the product, and slowing down the aging of the product. At the same time, in the utility model, the inner diameters of the first outer pipe 24 and the second outer pipe 32 adopt a uniform inner diameter, and there is no variable diameter and narrow gap in the entire first outer pipe 24 and the second outer pipe 32, which ensures the fluidity of the gas in the first outer pipe 24 and the second outer pipe 32 and improves the vacuum efficiency.
