It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0034] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0035] like Figures 1 to 3 As shown, a constant temperature and humidity chamber is provided according to one embodiment of the present invention, comprising:

[0036] Box 1 is used for maintaining constant temperature and humidity for materials;

[0037] Heat exchange component 2 is disposed on housing 1 and is used for heat exchange of housing 1. Heat exchange component 2 includes:

[0038] Cooling box 21 is fixedly installed on box body 1;

[0039] A heating box 22 is fixedly installed on the box body 1, and a heating rod 28 is fixedly installed on the heating box 22.

[0040] The delivery pump 23 is fixedly installed on the housing 1. A first three-way valve 24 is fixedly installed at its liquid inlet end. The first three-way valve 24 is connected to the heating box 22 and the cooling box 21 through the liquid inlet hot pipe 241 and the liquid inlet cold pipe 242, respectively.

[0041] The heat exchange pipeline 25 is fixedly installed on the housing 1. Its inlet end is connected to the outlet end of the delivery pump 23. The outlet end of the heat exchange pipeline 25 is connected to a second three-way valve 26. The second three-way valve 26 is connected to the heating box 22 and the water cooling mechanism 27 through the liquid supply heat pipe 261 and the liquid supply cold pipe 262, respectively.

[0042] The water-cooling mechanism 27 is fixedly installed on the cooling box 21;

[0043] Temperature sensor 29 is fixedly installed on housing 1.

[0044] Specifically, as a further embodiment of this utility model, the cooling tank 21, the liquid inlet cooling pipe 242, the first three-way valve 24, the delivery pump 23, the heat exchange pipe 25, the second three-way valve 26, and the liquid supply cooling pipe 262 constitute the first liquid flow path, and the heating tank 22, the liquid inlet heat pipe 241, the first three-way valve 24, the delivery pump 23, the heat exchange pipe 25, the second three-way valve 26, and the liquid supply heat pipe 261 constitute the second liquid flow path;

[0045] In this embodiment of the invention, during actual application, when cooling the housing 1, the first three-way valve 24 is connected to the cooling tank 21 through the liquid inlet cooling pipe 242, and the second three-way valve 26 is connected to the cooling tank 21 through the liquid supply cooling pipe 262. The delivery pump 23 is started, causing the liquid inside the cooling tank 21 to be transported to the heat exchange pipe 25, absorbing the heat inside the housing 1 and exchanging heat with the housing 1. Then, the liquid after heat exchange is cooled by the water cooling mechanism 27 and discharged back into the cooling tank 21. By circulating and freezing the liquid, the chamber 1 can be kept at a low temperature. When it is necessary to heat the chamber 1 to maintain a constant temperature, the first three-way valve 24 is connected to the heating chamber 22 through the liquid inlet heat pipe 241, and the second three-way valve 26 is connected to the heating chamber 22 through the liquid supply heat pipe 261. The heating rod 28 heats the liquid inside the heating chamber 22, and the delivery pump 23 is started to circulate the liquid inside the heating chamber 22. The liquid is transferred to the inside of the chamber 1 through the heat exchange pipe 25, thereby keeping the chamber 1 at a constant temperature.

[0046] By setting up the heat exchange component 2, the temperature of the chamber 1 can be controlled. Depending on the usage, the chamber 1 can be switched between heat absorption and cooling or heat conduction and heating to ensure good uniformity of heat conduction inside the chamber 1. Moreover, the convection heating method can also make the constant temperature effect inside the chamber 1 better. The integrated heat exchange equipment eliminates the need to install two separate heating and cooling equipment for the chamber 1, reducing the cost of using the chamber 1.

[0047] like Figure 1 and Figure 3 As shown, in a further embodiment of this utility model, a humidification component 3 is also included, disposed on the housing 1, for humidifying the interior of the housing 1. The humidification component 3 includes:

[0052] In this embodiment of the utility model, in actual application, the humidity sensor 34 detects the humidity inside the box 1, and then controls the power supply to and from the humidification pump 32 through the relay 35 and the controller 36, so that the inside of the box 1 is in a constant humidity state. Since the humidity sensor 34, the relay 35 and the controller 36 control the start and stop of the pump is a mature technical means in the prior art, the applicant will not elaborate on it here.

[0053] like Figure 1 and Figure 3 As shown, in a further embodiment of this utility model, an auxiliary heating component 4 is also included, disposed on the housing 1, for auxiliary heating of the interior of the housing 1. The auxiliary heating component 4 includes:

[0054] Auxiliary heating box 41 is fixedly installed on box 1. An auxiliary heating fan and an electric heating wire are fixedly installed on auxiliary heating box 41. An air inlet is also provided on auxiliary heating box 41.

[0056] Specifically, as a further embodiment of this utility model, it also includes a ventilation assembly 5, which is disposed on the housing 1 and used for ventilation inside the housing 1. The ventilation assembly 5 includes:

[0057] The air exchange box 51 is fixedly installed on the box 1. An air exchange fan is fixedly installed on the air exchange box 51, and an air outlet is also provided on the air exchange box 51.

[0059] In this embodiment of the present invention, when both the first sealing plate 43 and the second sealing plate 53 are in a closed state during actual application, the box 1 is in a sealed state, which improves its constant humidity and temperature effect. When heating the box 1, the first sealing plate 43 is extended and opened by the first telescopic rod 42, and the auxiliary heating fan blows the heat emitted by the heating wire into the box 1, shortening the heating time inside the box 1. When it is necessary to reduce the humidity inside the box 1, the second sealing plate 53 is extended and opened by the second telescopic rod 52, and the ventilation fan is started to accelerate the air flow inside the box 1, thereby completing dehumidification.

[0060] like Figure 1 As shown, as a further embodiment of the present utility model, a sealing door 11 is rotatably fitted on the box 1, and a control panel 12 is also fixedly installed on the box 1.
