Detailed Description
The thermal vacuum testing machine of the present invention will be described in further detail with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and fig. 2, the thermal vacuum testing machine comprises a box body 1 and a box cover 2, wherein the box body 1 is hinged with the box cover 2. The cover 2 is provided with a window 201, and a seal ring 202 is arranged around the view. The box body 1 is provided with a test box 3, a barrel-shaped heat sink 4 is arranged in the test box 3, and the inner surface of the heat sink 4 is coated with black paint with high absorption rate. The sealing ring 202 presses the heat sink 4 when the lid 2 is closed, so that sealing is achieved. The seal 202 may be a rubber roll or a silicon film. The outer surface of the heat sink 4 is covered with a refrigerating pipe 5 and a heating pipe 6, and a reinforcing layer 7 is covered on the refrigerating pipe 5 and the heating pipe 6. The heat sink 4 is made of the same material as the reinforcing layer 7, and is 304L stainless steel or Ni-based alloy. A group of guide rails 41 are arranged in the heat sink, a test bed 42 is movably arranged on the guide rails 41, an equipment room 8 is arranged on the right side of the test box 3, and a vacuumizing device 9, a heating device 10 and a refrigerating device 11 are arranged in the equipment room.
The main equipment of the vacuum-pumping device 9 is a vacuum pump. One end of the vacuum tube is hermetically connected with the inner wall of the heat sink 4 far away from the box cover 2, and the other end of the vacuum tube is connected with the vacuum pump.
The heating device 10 is an electric heating device, and the heating pipe 6 is a heat conduction pipe. An electric heating device is installed in the device chamber 8. If the heating device 10 is a heat-conducting oil heating device, the heating pipe 6 is a hollow pipe, and the material thereof is as follows: 304L stainless steel or a nickel-based alloy. The heat conducting oil may be silicone oil. An electric pump and a silicone oil recovery tank are required to be added in the equipment room, and silicone oil is circulated in the heating pipe 6 through the electric pump so as to heat the heat sink 4.

The utility model discloses but form high low temperature test machine working procedure as follows:
s1: the worker opens the door 2 and puts the object to be tested on the test stand 42 in the heat sink 4 (the test stand 42 can be pulled out through the guide rail 41). The box door 2 is closed, the numerical values such as the temperature, the measured time, the test times and the like required by the test are input on the operation table, and the key is started.
S2: the vacuum pump starts to vacuumize the heat sink 4, and simultaneously heats or refrigerates the heat sink 4 according to data input on the operation table. The operation table induces the temperature of the heat sink 4 through a temperature sensor in the heat sink, if the temperature is heated, the heating device 10 starts to work until the data induced by the temperature sensor is consistent with the numerical value input by the operation table; if the temperature is the refrigeration, the refrigeration device 11 works until the data sensed by the temperature sensor is consistent with the numerical value input by the operation table. And testing the vacuum pressure in the heat sink 4 in real time, and if the vacuum pressure exceeds the input numerical value, starting the operation of the vacuumizing device 9.
S3: before each refrigeration or heating, the heat sink 4 is vacuumized once, and when the test is finished and the test times are also finished, liquid nitrogen or silicon is pumped back into the respective recycling boxes. The tester stops working.
While the preferred embodiments or examples of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to the embodiments or examples, and various changes can be made without departing from the spirit of the invention within the knowledge of those skilled in the art.
