Referring to fig. 1, 2 and 3, fig. 1 is a schematic view showing a partial sectional structure of a connection between an insulating exhaust device 100 and an environmental test chamber (not shown) according to an embodiment of the present application, fig. 2 is a schematic view showing a sectional structure of the structure shown in fig. 1 at A-A, and fig. 3 is a schematic view showing a partial enlarged view of the structure shown in fig. 1 at B, wherein the insulating exhaust device 100 includes a first connection pipe 4, a vacuum pipe 3 and a connection member 2 according to an embodiment of the present application.

Wherein:

As shown in fig. 1 to 3, the first connecting pipe 4 is disposed in the accommodating space 1a of the environmental test chamber, and one end of the first connecting pipe 4 is used for connecting a product to be tested (not shown) disposed in the accommodating space 1a and generating high-temperature gas. The vacuum tube 3 comprises a second connecting tube 31 and a vacuum connecting tube 32, one end of the second connecting tube 31 penetrates through the box body 1 of the environment test box and is communicated with one end, deviating from a product to be tested, of the first connecting tube 4, and the other end of the second connecting tube 31 is arranged on the outer side of the box body 1. The vacuum connecting pipe 32 is sleeved on the periphery of the second connecting pipe 31, one end of the vacuum connecting pipe 32 penetrates through the box body 1 and is connected with the second connecting pipe 31 in the accommodating space 1a, the other end of the vacuum connecting pipe 32 is connected with the second connecting pipe 31 outside the box body 1, and a vacuum layer 3a is formed between the vacuum connecting pipe 32 and the second connecting pipe 31. The connecting piece 2 is used for connecting the vacuum connecting pipe 32 with the box body 1.

Referring to fig. 1, in the environmental test chamber, a housing space 1a is formed in a chamber 1, and a vent hole (not shown) is provided in the chamber 1, and penetrates through a side wall of the chamber 1 to communicate with the housing space 1 a. One end of a second connecting pipe 31 in the vacuum pipe 3 passes through the exhaust hole to be connected with a first connecting pipe 4 arranged in the accommodating space 1a, and the other end is arranged on the outer side of the box body 1 and is communicated with the external environment of the environment test box. One end of the first connecting pipe 4, which is far away from the vacuum pipe 3, can be communicated with an exhaust channel of a product to be tested for testing in the accommodating space 1a, so that gas generated in the testing process of the product to be tested can enter the heat-insulating exhaust device 100 through the exhaust channel, and then is exhausted to the external environment of the environment test box through the first connecting pipe 4 and the vacuum pipe 3.

As shown in fig. 2, the vacuum tube 3 may include a second connection tube 31 and a vacuum connection tube 32. Specifically, the inner diameter of the vacuum connection pipe 32 is larger than the outer diameter of the second connection pipe 31, and both ends of the vacuum connection pipe 32 are connected with the outer surface of the second connection pipe 31, so that the vacuum connection pipe 32 and the second connection pipe 31 can be enclosed together to form a closed air gap space layer, and the vacuum layer 3a can be formed between the vacuum connection pipe 32 and the second connection pipe 31 by performing complete vacuum pumping treatment on the air gap space layer. The vacuum layer 3a can effectively block heat in the second connection pipe 31 from being transferred to the vacuum connection pipe 32. Wherein, because both ends of the vacuum connecting pipe 32 are respectively positioned at the inner side and the outer side of the box body 1, the vacuum layer 3a is arranged at the joint of the vacuum tube 3 and the box body 1, so the vacuum tube 3 can obstruct the heat in the vacuum tube 3 from being transferred to the box body 1 by utilizing the characteristic of poor heat conducting property of the vacuum layer 3a. Therefore, when the gas with high temperature heat flows through the vacuum tube 3, the vacuum layer 3a can function as vacuum insulation to avoid the high temperature of the cabinet 1 due to heat transfer.

In order to ensure that the gas generated from the product to be tested can be smoothly discharged out of the case 1, the first connecting pipe 4 and the vacuum pipe 3 should be completely sealed, which is advantageous in that the test process does not have the problem of inaccurate test or safety due to the problem of air leakage of the heat-insulating exhaust apparatus 100.

In the above-mentioned thermal insulation exhaust device 100, one end of the first connecting pipe 4 disposed in the accommodating space 1a of the environmental test chamber is communicated with the product to be tested which generates high temperature gas, the other end is communicated with the second connecting pipe 31, and one end of the second connecting pipe 31 deviating from the first connecting pipe 4 is disposed at the outer side of the environmental test chamber, so that the gas generated by the product to be tested can be smoothly led out of the chamber 1 through the first connecting pipe 4 and the vacuum pipe 3, thereby avoiding that the gas generated by the product to be tested accumulates in the accommodating space 1a to affect the development of the test. In addition, since the two ends of the vacuum connecting pipe 32 sleeved on the outer periphery of the second connecting pipe 31 are respectively connected with the second connecting pipe 31 in the accommodating space 1a and outside the box body 1, and a vacuum layer 3a is formed between the vacuum connecting pipe 32 and the second connecting pipe 31, in the exhaust process, the vacuum pipe 3 can utilize the vacuum characteristic of the vacuum layer 3a to perform heat blocking so as to prevent heat in gas from being transferred to the box body 1, and further, the function of the environmental test box can be prevented from being influenced due to the overhigh temperature of the box body 1.

It will be appreciated that if the vacuum connection tube 32 or the second connection tube 31 in the vacuum tube 3 is broken so that the air gap space layer formed has a sealing problem, the desired vacuum layer 3a cannot be obtained by performing the vacuum-pumping treatment on the air gap space layer. At this time, the damaged pipe body needs to be replaced or repaired so that the air gap space layer surrounded by the vacuum connecting pipe 32 and the second connecting pipe 31 has good sealing performance, and then the vacuum layer 3a can be formed between the vacuum connecting pipe 32 and the second connecting pipe 31 when the air gap space layer is vacuumized, so that the vacuum layer 3a can be ensured to realize a corresponding heat insulation function in the exhaust process.

In one embodiment, as shown in fig. 1 to 3, the connector 2 is detachably connected with the case 1. When the connection between the connector 2 and the case 1 is detachable, it is advantageous to easily detach or replace the vacuum tube 3. Specifically, when the vacuum tube 3 needs to be disassembled or replaced, the connection between the connecting piece 2 and the box body 1 is only required to be released, and the part of the vacuum tube 3, which is arranged in the accommodating space 1a, can be extracted, so that the box body 1 and the vacuum tube 3 are separated, and the vacuum tube 3 is replaced or inspected.

Further, the connecting piece 2 is a flange, the flange is sleeved on the periphery of the vacuum connecting pipe 32, and the flange is in threaded connection with the box body 1. When the connecting piece 2 is a flange, the box body 1 and the vacuum tube 3 can be conveniently fixed, and the reliability of the connection of the box body 1 and the vacuum tube 3 can be ensured.

Alternatively, the flange may be welded around the outer circumference of the vacuum connection tube 32.

Alternatively, the number of flanges for connecting the vacuum tube 3 and the case 1 may be two, and the two flanges are respectively connected to the inner surface and the outer surface of the sidewall of the case 1.

In one embodiment, as shown in fig. 3, the heat-insulating exhaust apparatus 100 further includes a heat-insulating plate 6, and the heat-insulating plate 6 is located between the connection member 2 and the case 1. Since the connection member 2 is connected to the vacuum connection tube 32, part of the heat of the gas passing through the vacuum tube 3 is transferred to the outer surface of the vacuum connection tube 32 of the vacuum tube 3, and thus transferred to the connection member 2 through the vacuum connection tube 32. Therefore, the heat insulation board 6 is arranged between the connecting piece 2 and the box body 1, which is favorable for preventing heat in the connecting piece 2 from being transferred to the box body 1, and further avoiding scalding staff or damaging the box body 1 and other structures arranged on the box body 1 due to overhigh temperature of the box body 1.

Further, the heat insulating plate 6 is a foamed silicone rubber or glass fiber cloth plate. The foaming silicon rubber and the glass fiber cloth plate have good heat insulation performance, and the heat transfer from the connecting piece 2 to the box body 1 can be effectively avoided when the foaming silicon rubber or the glass fiber cloth plate is used as the heat insulation plate 6.

In one embodiment, the second connecting pipe 31 comprises a connecting section and a vacuum connecting section, the connecting section is arranged on the outer side of the box body 1, the connecting section is communicated with one end of the vacuum connecting section, one end of the vacuum connecting section deviating from the connecting section passes through the box body 1 and is communicated with the first connecting pipe 4, the vacuum connecting pipe 32 is sleeved on the periphery of the vacuum connecting section, two ends of the vacuum connecting pipe 32 are respectively connected with two ends of the vacuum connecting section, and the vacuum layer 3a is formed between the vacuum connecting pipe 32 and the vacuum connecting section. Illustratively, the vacuum connecting pipe 32 is sleeved on the periphery of the vacuum connecting section, and two ends of the vacuum connecting pipe 32 are respectively connected with two ends of the vacuum connecting section, so that a closed air gap space layer can be formed between the vacuum connecting pipe 32 and the vacuum connecting section, and a vacuum layer 3a can be formed between the vacuum connecting pipe 32 and the vacuum connecting section by performing complete vacuumizing treatment on the air gap space layer. Wherein, when the both ends of vacuum connecting pipe 32 are located the inboard and the outside of box 1 respectively, vacuum layer 3a is located the junction of vacuum tube 3 and box 1, this realization heat-proof effects when not only can utilizing vacuum layer 3a to realize vacuum tube 3 and box 1 to be connected, can also reduce the heat that the gas transferred to accommodation space 1a when passing through vacuum tube 3 through vacuum layer 3a, and then be favorable to guaranteeing the temperature stability in the accommodation space 1a, guarantee experimental accuracy.

Wherein, when vacuum pipe 3 is connected with first connecting pipe 4, the both ends of vacuum connecting pipe 32 are located the inboard and the outside of box 1 respectively, and vacuum layer 3a is located the junction of vacuum pipe 3 and box 1, and this can not only utilize vacuum layer 3a to realize the thermal-insulated effect when vacuum pipe 3 is connected with box 1, can also guarantee that the surface temperature of the vacuum pipe 3 that exposes outside box 1 is lower, and then avoid exposing outside box 1 vacuum pipe 3 because of the high temperature scald staff.
