[0052] It should also be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element.

[0053] Please see Figure 1-5As shown, in one embodiment of this utility model, a temperature control cabinet includes a housing 10, and the housing 10 is provided with a heat exchange cavity 13. A first flow equalization element 30 and a temperature control component are sequentially arranged within the heat exchange cavity 13 along the airflow direction. The first flow equalization element 30 is arranged around the outside of the temperature control component. In this embodiment, the temperature control component includes a cooling element 40 and a heating element 50. After the airflow exchanges heat with the cooling element 40, the airflow is cooled to below the target temperature. The heating element 50 heats the cooled airflow to bring its temperature to the target value. The cooling element 40 and the heating element 50 are existing technologies and will not be described in detail here. Within the heat exchange cavity, the airflow is equalized by the first flow equalization element before flowing through the temperature control component. The first flow equalization element 30 is arranged around the outside of the temperature control component, providing uniform incoming flow conditions for the temperature control component. The airflow can exchange heat evenly with the temperature control component, effectively improving the temperature uniformity of the airflow supplied to the controlled space.

[0054] In a further optimized design, the first flow equalization element 30 is provided with flow equalization holes 320, wherein the number of flow equalization holes 320 gradually increases along the flow equalization path direction of the first flow equalization element. The flow equalization path direction of the first flow equalization element mentioned in this document refers to the path of the airflow through the first flow equalization element (e.g., Figure 5 As shown), regarding the number of flow equalization holes 320, the position reached by the first flow equalization element by the airflow is less than the position reached by the first flow equalization element by the airflow, which can effectively improve the flow equalization effect of the first flow equalization element 30 on the airflow and provide more uniform incoming flow conditions for the temperature control component. Specifically, in this embodiment, the first flow equalization component 30 includes a first flow equalization section 31 and two second flow equalization sections 32 extending from both ends of the first flow equalization section 31. The first flow equalization section 31 and the second flow equalization section 32 are arranged at a 90-degree angle. In other embodiments, the specific arrangement can be made according to the actual situation. The first flow equalization section 31 and the second flow equalization section 32 are arranged at a set angle. The projection of the temperature control component in the airflow direction of the heat exchange cavity 13 is located within the enclosed space formed by the first flow equalization section 31 and the two second flow equalization sections 32. For the first flow equalization section 31, the airflow arrives at all points of the first flow equalization section 31 simultaneously. The number of flow equalization holes is not evenly distributed, but the airflow first arrives at the end of the second flow equalization section 32 near the first flow equalization section 31, and then arrives at the end of the second flow equalization section 32 away from the first flow equalization section 31 (e.g., Figure 5As shown, the number of flow equalization holes 320 in the second flow equalization section 32 near the end of the first flow equalization section 31 is less than the number of flow equalization holes 320 in the second flow equalization section 32 away from the end of the first flow equalization section 31. The airflow is equalized from one side of the first flow equalization section 31 and one side of the two second flow equalization sections 32 and then enters the enclosed space, flowing to the cooling component 40. Before heat exchange with the cooling component 40, the airflow is equalized by multiple flow equalization sections and flows into the top of the cooling component 40 from three sides, providing a uniform flow to the cooling component 40.

[0055] Please see Figure 2-4 As shown, in one embodiment of this utility model, the distance between the top end of the second flow equalization section 32 and the side wall of the heat exchange cavity 13 is greater than the distance between the bottom end of the second flow equalization section 32 and the side wall of the heat exchange cavity 13. The two second flow equalization sections 32 of the first flow equalization member 30 are inclined towards each other. The airflow enters the enclosed space from the gap between the second flow equalization section 32 and the side wall of the heat exchange cavity 13 and flows to the cooling member 40. The two second flow equalization sections 32 are inclined towards each other, which effectively increases the flow equalization cross-sectional area of ​​the second flow equalization section 32 and improves the flow equalization effect.

[0056] Please see Figure 1-5As shown, in one embodiment of this utility model, a temperature control cabinet includes a housing 10 and a fan 20. The fan 20 is a centrifugal fan. In other embodiments, the fan type may also be an axial fan or other types, depending on the specific situation. The housing 10 is provided with an air inlet 11, an air inlet cavity 12, a heat exchange cavity 13, and an air outlet 14 connected in sequence. The fan 20 is disposed in the air inlet cavity 12 and close to the first flow equalization section 31. The fan 20 drives the airflow to flow in from the air inlet 11, and after flowing through the air inlet cavity 12 and the heat exchange cavity 13, it is discharged from the air outlet 14. In the heat exchange cavity 13, a first flow equalization element 30, a cooling element 40, a heating element 50, and a second flow equalization element 60 are arranged in sequence along the airflow direction of the heat exchange cavity 13. The cooling element 40, the heating element 50, and the second flow equalization element 60 are arranged in parallel and at intervals along the airflow direction of the heat exchange cavity 13. The fan 20 drives the gas to flow into the heat exchange chamber 13 through the air inlet 11 and the air inlet cavity 12. Inside the heat exchange chamber 13, the airflow is evenly distributed by the first flow equalizer 30 (e.g., a flow equalizer plate, flow equalizer mesh, etc., with flow equalizer holes for equalization) before passing through the cooling element 40 and the heating element 50. The cooling element 40, the heating element 50, and the second flow equalizer 60 are arranged sequentially and parallel to each other along the airflow direction within the heat exchange chamber 13. The airflow is undisturbed in other directions during cooling and heating, resulting in uniform heat exchange. Before being discharged from the air outlet 14, the airflow is further evenly distributed by the second flow equalization component 60 (e.g., a flow equalization plate, a flow equalization mesh, etc., with flow equalization mesh holes for flow equalization). The airflow velocity and direction at the air outlet 14 are uniform, which can effectively improve the temperature uniformity of the airflow supplied to the controlled space. In this embodiment of the utility model, the temperature control cabinet can output airflow at a constant temperature from the air outlet 14, effectively reducing the temperature difference in various parts of the supplied airflow and achieving high temperature uniformity of the supplied airflow. In this embodiment, the second flow equalization component 60 is a honeycomb flow equalization plate. In other embodiments, it is set according to the specific situation.

[0057] Please see Figure 2-3 As shown, in one embodiment of this utility model, the temperature control cabinet further includes a third flow equalization element 70, which is disposed between the fan 20 and the first flow equalization element 30. The addition of the third flow equalization element 70 between the fan 20 and the first flow equalization element 30 further improves the flow equalization effect.

[0058] Please see Figure 2-3 As shown, in one embodiment of this utility model, the housing 10 further includes a static pressure cavity 15. The air inlet cavity 12, the static pressure cavity 15 and the heat exchange cavity 13 are connected in sequence. When the airflow passes through the static pressure cavity 15 before being equalized by the first flow equalization member 30, the airflow resistance can be reduced, the wind noise can be buffered and dispersed, and the transmission of noise can be reduced.

[0059] Please see Figure 2-3 As shown, in one embodiment of this utility model, the heat exchange cavity 13 is rectangular, and the cooling element 40 and the heating element 50 are arranged in parallel and spaced apart along the height direction of the heat exchange cavity 13. The height of the heat exchange cavity 13 is less than its length or width. The parallel placement of the cooling element 40 and the heating element 50 along the height direction of the heat exchange cavity 13 effectively utilizes the internal space of the heat exchange cavity 13 to accommodate a large area of ​​cooling element 40 and heating element 50, maximizing the heat exchange area, improving the heat exchange effect, and ensuring uniform heat exchange between the airflow and the cooling element 40 and heating element 50.

[0060] Please see Figure 1-2 As shown, in one embodiment of this utility model, the housing 10 is provided with an inspection port communicating with the heat exchange cavity 13. The inspection port is aligned with the heat exchange cavity 13 along its length direction, and the housing 10 is provided with an inspection cover plate 16 for sealing the inspection port. The cooling element 40 and the heating element 50 are arranged sequentially at intervals and parallel to each other along the height direction of the heat exchange cavity 13, and the inspection port is aligned with the heat exchange cavity 13, allowing for convenient maintenance of the cooling element 40 and the heating element 50.

[0061] Please see Figure 2-4 As shown, in one embodiment of this utility model, the housing 10 further includes a water channel cavity 17 and an electrical control cavity 18. The water channel cavity 17 is used to install and arrange water pipes, and the electrical control cavity 18 is used to install and arrange control circuits. The independent arrangement of the water channel cavity 17 and the electrical control cavity 18 facilitates wiring and water channel arrangement, ensuring no interference between them.

[0062] Please see Figure 1-5 As shown, in one embodiment of this utility model, the air inlet 11 and the air outlet 14 are arranged perpendicularly to each other. For other embodiments, please refer to... Figure 6-7 As shown, the air inlet 11 and the air outlet 14 are arranged parallel to each other. The positions of the air inlet 11 and the air outlet 14 are flexibly set and can be selected according to actual needs.

[0063] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
