All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 3, the embodiment provides an ice tray cold and hot impact testing machine, which comprises a condenser 1, a compressor 2 and an aging chamber 3, wherein an evaporator 6 is arranged in the aging chamber 3, a connecting pipeline is arranged between the compressor 2 and the evaporator 6, the connecting pipeline is of a T-shaped structure, one end of the connecting pipeline is connected with a water inlet pipe of the condenser 1, the other end of the connecting pipeline is connected with the evaporator 6, an electromagnetic valve 5 is further arranged on a pipeline leading to the evaporator 6, a third port is connected with the compressor 2, a water outlet pipe of the condenser 1 is connected with the evaporator 6 through a pipeline, a capillary pipe is arranged at a joint of the condenser 1 and the evaporator 6, and the evaporator 6 is connected with the compressor 2 through a pipeline.

In this embodiment, a heating circulation line is formed among the compressor 2, the connection line, the solenoid valve 5, and the evaporator 6. The compressor 2 compresses freon into a liquid, releasing heat, and at the same time, also converts freon into a high temperature liquid for supplying heat to the evaporator 6. When the evaporator 6 needs to be heated by heat supply, the electromagnetic valve 5 is opened to discharge high-temperature and high-pressure liquid from the compressor, and the liquid directly enters into a copper pipe of the evaporator 6 of the ice maker through the electromagnetic valve 5, so that the test workpiece is heated, and the evaporator of the ice maker is quickly heated to about 40 ℃.

After the electromagnetic valve 5 is closed, the compressor 2, the condenser 1 and the evaporator 6 form a refrigerating system, and the evaporator 6 is subjected to cooling and refrigerating operation.

The condenser mainly comprises radiating fins, a fan and a condensing copper pipe. The condenser is connected with a cold source and a heat source and an ice machine evaporator through copper pipes, when the electromagnetic valve 5 is closed, high-temperature and high-pressure Freon liquid flows into a condensing copper pipe of the condenser 1 through the connection of the copper pipes, a fan on the condenser blows, the high-temperature and high-pressure Freon liquid flowing into the condensing copper pipe is reduced into low-temperature liquid through the cooperation of the cooling fins and the fan, and the low-temperature Freon liquid flows into a coil pipe of the ice machine evaporator of a test workpiece through the copper pipes connected with the condenser 1 and the evaporator 6. Due to the physical characteristics of Freon, the evaporating temperature is about-40 ℃, and the Freon enters the evaporator of the ice machine to evaporate and absorb heat, so that the evaporator of the ice machine is quickly reduced to about-20 ℃.

The ageing room 3 is also provided with two time relays 4 and a temperature controller, the temperature controller is connected with the two time relays 4, the test temperature of the evaporator of the ice maker of the test workpiece can be detected, the operation of different time relays is controlled according to whether the displayed temperature reaches the temperature required by the test, and the refrigerating and heating modes and the time of the time relays are regulated to control the opening and closing of the electromagnetic valve 5 and the operation of the condenser 1.

One time relay 4 is connected with the electromagnetic valve 5 to control the opening and closing of the electromagnetic valve 5, and the other time relay 4 is connected with the condenser 1 to control the work of the condenser 4.

One of the time relays 4 is used for setting, adjusting and controlling the opening time of the electromagnetic valve according to the temperature fed back by the temperature controller, and controlling the heating time. The other time relay 4 sets the working time of the fan according to the temperature fed back by the temperature controller, reduces the freon temperature, sprays and atomizes through capillary throttling, and flows into the ice maker evaporator 6 for evaporation cooling, and controls the cooling time. When the heating time relay 4 is in the set time data, the timing is automatically stopped, the power is cut off, the refrigerating time relay 4 starts to time, the refrigerating system is powered on, when the refrigerating time is in the set time data, the timing is automatically stopped, the power is cut off, the heating time relay 4 starts to time, the power is powered on, and the refrigerating system always reciprocates.

The time relay 4 and the temperature controller are both purchased from the market, the temperature controller is a digital display function temperature controller produced by Shanghai Hui sea electrical equipment limited company, the time relay is DH48S, and the specific use method is the prior art and is not repeated here.

The evaporator 6 may be placed directly inside the ageing chamber 3.

Simultaneously, the refrigerating time relay 4 starts timing, the cooling fan is powered, the fan works, the condenser 1 flowing into high-temperature freon is cooled, low-temperature freon is sprayed and atomized through capillary throttling, and flows into the copper pipe of the ice maker evaporator 6 to evaporate and absorb heat, the ice maker evaporator 6 is refrigerated and cooled, the fan stops working when the set time reaches the required test temperature, the heating time relay 4 starts timing again, the electromagnetic valve 5 is opened, and the ice maker evaporator is heated and warmed. (because the capillary tube is throttled between the condenser 1 and the ice maker evaporator 6, the flow is very small, the resistance is very large, and after the electromagnetic valve 5 is opened, the Freon short circuit with high temperature and high pressure enters the ice maker evaporator to supply heat preferentially through the electromagnetic valve). The cycle is repeated, the full-automatic heating and refrigerating conversion is realized, and the continuous cold and hot circulation test is carried out for 24 hours under the condition of no power failure.
