[0014] Figure 1 This is a side view structural diagram of the environmental simulation test chamber in an embodiment of this utility model. Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0016] like Figure 1 As shown in the figure, an energy-saving environmental simulation test chamber proposed in this embodiment of the present invention includes an inner chamber 1 and an outer chamber 2; the inner chamber 1 and the outer chamber 2 are separated.
[0017] The outer casing 2 contains a compressor 3 and a condenser 4, as well as a first solenoid valve 5 and a second solenoid valve 6; the outer casing 2 is open to the atmosphere.
[0018] The inner chamber 1 is divided into a front chamber 101 and a rear chamber 102, which are connected. An electric heater 7, an evaporator 8, and a coil 9 are provided in the rear chamber 102. An air duct is also provided in the rear chamber 102 to form a reciprocating airflow from the rear chamber 102 to the front chamber 101.
[0019] The outlet of the compressor 3 is connected to one end of the first solenoid valve 5 and one end of the second solenoid valve 6 via pipelines. The other end of the first solenoid valve 5 is connected to one end of the coil 9 via a pipeline. The other end of the second solenoid valve 6 is connected to the inlet of the condenser 4 via a pipeline. The other end of the coil 9 is connected to the pipeline between the second solenoid valve 6 and the condenser 4 via a pipeline.
[0020] The above describes the key structure of the energy-saving environmental simulation test chamber proposed in this embodiment; the remaining piping systems can be the same as those in existing technologies; for example:
[0021] The outlet of the condenser 4 is connected to the inlet of a liquid storage tank through a pipeline, the outlet of the liquid storage tank is connected to one end of a drying filter through a pipeline, the other end of the drying filter is connected to one end of a third electromagnetic valve through a pipeline, the other end of the third electromagnetic valve is connected to one end of a capillary tube through a pipeline, the other end of the capillary tube is connected to one end of the evaporator 8 through a pipeline, and the other end of the evaporator 8 is connected to the inlet of the compressor 3 through a main return pipeline.
[0022] When a test at a higher temperature (for example, 50-80℃) is needed, the second electromagnetic valve 6 can be closed and the first electromagnetic valve 5 can be opened; at this time, the high-temperature and high-pressure gaseous refrigerant (the temperature can be above 100℃) from the compressor 3 first passes through the pipeline where the first electromagnetic valve 5 is located and then passes through the coil 9 in the rear chamber 102, so that the air in the rear chamber 102 can be heated; at this time, the heating power of the electric heater 7 can be reduced, and the effect of energy saving can be achieved; the heated air in the rear chamber 102 flows to the front chamber 101 along the airflow direction; the front chamber 101 is used to place objects subjected to environmental simulation tests, for example, some electronic devices.
[0023] When a test at a lower temperature (for example, -20-0℃) is needed, the second electromagnetic valve 6 can be closed and the first electromagnetic valve 5 can be opened; the evaporator 8 absorbs heat to refrigerate, and the refrigerant passing through the coil 9 is cooled and then enters the condenser 4, so that the condensing efficiency of the condenser 4 can be improved.
[0024] When a test at an extremely low temperature (for example, -45-40℃) is needed, the first electromagnetic valve 5 can be closed and the second electromagnetic valve 6 can be opened; the high-temperature and high-pressure gaseous refrigerant from the compressor 3 no longer bypasses the coil 9 in the rear chamber 102, but directly enters the condenser 4, so that the rear chamber 102 can obtain a low temperature that is low enough.
[0025] More preferably, a partition plate 10 is arranged between the front chamber 101 and the rear chamber 102, and the partition plate 10 is provided with air holes; the partition plate 10 can prevent the objects from colliding with the electric heater 7 or the evaporator 8, and protect the components in the rear chamber 102.
[0026] In some specific embodiments, the coil 9 can be arranged around the evaporator 8.
[0027] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limiting; although the present application has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
