Problems solved by technology

[0003] Since the product to be tested needs to be connected to the device before the test, and in the actual use process, there may be cases where the product to be tested is not connected to the device or the connection is not in place. At this time, turning on the device for water delivery will cause water to spray out directly. In addition, there are usually electronic components in the test site, and the accidental spraying of water may easily lead to safety hazards or damage to electronic components.

Embodiment 1

[0038] Embodiment 1: A kind of safe aging test constant temperature machine, such as figure 1 and figure 2As shown, a vertical body 1 is included, a water tank 2 is arranged inside the body 1, a water delivery pipeline 4 is connected to the water tank 2 and a water pump 3 for providing power is provided on the water delivery pipeline 4, the water delivery pipeline 4 Including the main pipeline 41 at the front section and four branches 42 at the end, the tail ends of each branch 42 penetrate to the front of the body 1 and form water outlets 5 arranged at vertical intervals; at the same time, a return pipe is connected to the water tank 2 6, the return water pipeline 6 also has 4 and is used for one-to-one correspondence with each branch 42, the end of the return water pipeline 6 also passes to the front of the body 1 and forms the return water interface 7, wherein the water outlet interface 5 and the water return interface 7 are used to connect respectively with the two ends ...

Embodiment 2

[0045] Embodiment 2: a kind of safe aging test constant temperature machine, such as Figure 4 As shown, the difference from Embodiment 1 is mainly that a pressure relief valve 28 is added on the pressure measuring pipeline 27 and a blocking member 29 is added on the gas transmission pipeline 18; thus, the pressure in the pressure measuring pipeline 27 reaches the corresponding limit pressure The pressure can be relieved in time through the pressure relief valve 28, so as to avoid the situation that the continuous increase of the pressure of the pressure measurement pipeline 27 caused by continuous gas transmission will cause damage to the product 38 to be tested, and further protect the product 38 to be tested, and the pressure relief valve The gas discharged from the exhaust port of 28 is connected to the blocking member 29 to drive the blocking member 29 to close the gas pipeline 18, so as to automatically cut off the gas pipeline 18, which is more convenient without manual ...

Abstract

The invention discloses a safe aging test constant temperature machine, which comprises a machine body, a water tank is arranged inside the machine body, a connected water delivery pipeline and a water return pipeline are arranged on the water tank, the water delivery pipeline is connected with a water pump, and the end of the water delivery pipeline far away from the water tank is on the machine body A water outlet interface for connecting the product to be tested is formed on the body, and the end of the return water pipeline away from the water tank forms a water return interface for connecting the product to be tested. A pressure measuring pipeline is formed between the valves, the pressure measuring pipeline is connected with a gas pipeline and is equipped with a pressure measuring piece, and a stop valve and a one-way valve are set on the gas pipeline; The shut-off valves are all closed, and the gas is delivered to the pressure measurement pipeline through the gas transmission pipeline, and the connection status of the product to be tested can be judged by the pressure change on the pressure measurement piece, which can effectively avoid accidents when the product to be tested is not connected or the connection is abnormal. When the equipment is turned on for water transfer, the safety is better.

Description

technical field [0001] The invention relates to the field of aging test equipment, more specifically, it relates to a safe aging test constant temperature machine. Background technique [0002] Aging test refers to the process of simulating the various factors involved in the actual use conditions of the product to carry out corresponding condition strengthening experiments on the aging of the product. Many existing electronic components need to be tested in a constant temperature environment, such as the battery power supply. Aging test, the product to be tested is connected to the aging test constant temperature through pipelines, and the water pump in the aging test thermostat pumps the water in the water tank to flow through the product to be tested and finally flows back into the water tank, thereby controlling the water temperature. Make the temperature of the product to be tested in a suitable temperature environment to facilitate its corresponding aging test. [000...
