[0022] like Figure 1-Figure 3 As shown, it relates to a constant temperature box with uniform temperature distribution, including a box body 1, multiple heat conduction plates 2 are fixed at equal distances inside the box body 1, and the interior of the heat conduction plates 2 is hollow, a top box 3 and a fan 4 are fixed on the upper surface of the box body 1, an electric heating wire 5 is installed inside the top box 3, and a refrigeration component 6 is installed on the top wall of the top box 3, an exhaust duct 42 is connected to the air inlet of the fan 4 and the side wall of the top box 3, an exhaust duct 41 connected to multiple heat conduction plates 2 is fixed to the air outlet of the fan 4, a return duct 31 connected to the heat conduction plate 2 is fixed on the side of the top box 3 away from the exhaust duct 42, a support component 7 is installed on the upper surface of each heat conduction plate 2, a plurality of reinforcement components 9 are fixed to the outer side wall of the bottom end of the box body 1, a box door 11 is rotatably connected to one side of the box body 1 through a hinge, and a plurality of universal wheels 10 are installed on the lower surface of the box body 1.

[0023] The refrigeration assembly 6 includes a compressor, an expansion valve, a dryer, a condenser and an evaporator 61 . The evaporator 61 is located inside the top box 3 .

[0024] The refrigeration component 6 has the same principle as the existing constant temperature box refrigeration system. The air inside the top box 3 can be cooled through the evaporator 61, and then driven by the fan 4, the cooled air can be blown into the heat conduction plate 2, and the heat conduction plate 2 is used to cool the inside of the box body 1.

[0025] An air inlet pipe 21 and an air outlet pipe 22 are fixedly connected at both ends of each heat conducting plate 2 . The other end of the air inlet pipe 21 is connected to the exhaust pipe 41 , and the other end of the air outlet pipe 22 is connected to the return pipe 31 .

[0026] Therefore, the heat conducting plate 2 is connected with the fan 4 and the top box 3, so that the hot air or cold air in the top box 3 can circulate into the heat conducting plate 2, and the heat conducting plate 2 is used to heat or cool the inside of the box body 1.

[0027] A temperature sensor 8 is installed on the inner wall of the box body 1 and above each heat conducting plate 2 .

[0028] The temperature of each area inside the box 1 can be monitored by multiple temperature sensors 8 .

[0029] The support assembly 7 includes vertical rods 71 ​​fixed to both sides of the upper surface of the heat conducting plate 2 , and the top ends of the vertical rods 71 ​​are fixedly connected to grid plates 72 .

[0030] When placing the test product inside the box 1 , the product can be placed on the surface of the grid plate 72 to avoid direct contact between the product and the heat conducting plate 2 .

[0031] The reinforcement assembly 9 includes a side plate 91 fixed to the outer side wall of the box body 1 , a screw rod 92 passes through the middle of the side plate 91 and is threadedly connected, and a backing plate 93 is fixedly connected to the bottom end of the screw rod 92 .

[0033] A transparent viewing window is fixed in the middle of the box door 11, so that the detection status of the product inside the box body 1 can be observed through the viewing window.

[0034] Working principle: When the thermostat is heating, the refrigeration component 6 is turned off, and then the electric heating wire 5 is started, and at the same time, the fan 4 is started. The electric heating wire 5 will heat the air inside the top box 3, and the fan 4 will then extract the heated air and send it to multiple heat conducting plates 2 along the exhaust pipe 41, and use multiple heat conducting plates 2 to heat various areas in the box body 1, and then the air will return to the top box 3 along the return pipe 31, thus circulating. When it is necessary to cool the inside of the box body 1, turn off the electric heating wire 5, turn on the refrigeration component 6, use the fan 4 to send the cold air in the top box 3 to multiple heat conducting plates 2, and use the heat conducting plates 2 to cool various areas inside the box body 1. Therefore, when the thermostat is in use, it can ensure that the temperature of each internal area is uniform, and improve the accuracy of detection.
