Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a constant temperature structure and control cabinet. Background Technology

[0002] Existing thermostatic control cabinets generally use internal fans to promote air circulation, combined with cooling and heating modules to achieve constant temperature. However, the air circulation method inside the cabinet is simplistic and does not take into account the natural physical properties of hot and cold air. During cooling, cold air is blown directly into the cabinet by the fan and sinks naturally, while hot air accumulates in the upper part of the cabinet and is difficult to be effectively carried out, resulting in a temperature difference between the upper and lower spaces and localized overheating. During heating, the situation is reversed, with hot air rising and accumulating at the top of the cabinet, while the lower space heats up slowly and has poor temperature uniformity. This mixing and ineffective circulation of hot and cold air not only reduces temperature control efficiency and increases energy consumption, but may also cause the electronic components inside the cabinet to degrade in performance or have their lifespan shortened due to uneven heating. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a constant temperature structure and control cabinet that can intelligently switch the airflow circulation direction through the coordinated control of valve group and air duct. When cooling, it guides hot air to be discharged from the top and injected into the bottom cold air, and when heating, it guides cold air to be discharged from the bottom and injected into the top hot air. This effectively adapts to and enhances the natural convection effect of hot and cold air, completely solves the technical drawbacks of uneven temperature and mixed hot and cold air in the cabinet, significantly improves temperature control efficiency and uniformity, and ensures the operational reliability and service life of internal electronic components.

[0004] This utility model also provides a constant temperature structure as described above, including: a box body, a box door on the front, and an internal cavity; The air ducts are installed on the inner side wall of the enclosure, and there are two of them located on both sides of the enclosure. The blower component is located at the top of the air duct; An air inlet valve is located on the upper surface of the blower component; Air outlet valve, located at the top of the air duct; Guide components are located at the bottom of the air duct; The temperature control components are located at the top and bottom of the chamber.

[0005] This utility model also has the following technical features: In one embodiment of this utility model, a partition is fixedly connected to the inner side wall of the box, and the partition is located on the side of the air duct.

[0006] In one embodiment of this utility model, the side surface of the air duct is fixedly connected to the inner side wall of the box.

[0007] In one embodiment of the present invention, the blowing component includes a wind frame, a motor and a fan. The side surface of the motor is fixedly connected to the inner side wall of the wind frame, and the output end of the motor is fixedly connected to the fan. The motor and the fan are multiple and arranged in an array inside the wind frame.

[0008] In one embodiment of this utility model, the lower surface of the air frame is fixedly connected to the upper surface of the air duct, and the fan faces the upper surface of the air duct.

[0009] In one embodiment of this utility model, the air inlet valve is connected to the middle of the air frame, and the end of the air inlet valve away from the air frame is in contact with the side surface of the partition. A sealing ring is provided between the air inlet valve and the partition.

[0010] In one embodiment of this utility model, the air outlet valve is located directly below the air blowing component, and the end of the air outlet valve away from the air duct is in contact with the inner side wall of the air frame away from the cavity. A sealing ring is provided between the air outlet valve and the air frame.

[0011] In one embodiment of this utility model, the guiding component includes a guide rod, an arc plate, and a baffle. The end of the guide rod is fixedly connected to the inner side wall of the arc plate, the side surface of the arc plate is movably connected to the inner side wall of the box, the end of the baffle is fixedly connected to the side surface of the guide rod, and the end of the baffle away from the guide rod is rotatably connected to the lower surface of the air duct.

[0012] In one embodiment of this utility model, the temperature-regulating component includes a cooling module and a heating module, which are respectively fixedly connected to the inner sidewalls of the upper and lower ends of the housing. A control cabinet, characterized in that it includes a constant temperature structure as described in any one of the above claims.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Equipped with an air inlet valve, it can seal the connection between the top of the blower and the air duct and the interior of the housing, respectively. Together with the exhaust valve, it can seal the connection between the bottom of the blower and the interior of the housing and the air duct, respectively. This allows control over whether the blower blows air from inside the air duct into the housing or air from inside the housing into the air duct. During cooling, when the cold air settles, it allows the hot air inside the housing to pass through the top of the air duct guide device. During heating, when the hot air rises, it allows the cold air inside the housing to pass through the bottom of the air duct guide device. This ensures uniform cooling and heating of electronic components and prevents the mixing of hot and cold air with the original air inside the housing, which would lead to uneven cooling and heating.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] It should be noted that the core defect of an existing constant temperature structure and control cabinet is uneven internal temperature distribution, resulting in low thermal management efficiency due to the mixing of hot and cold air. Furthermore, it fails to utilize the natural physical law of cold air sinking and hot air rising, causing hot air to accumulate at the top during cooling and difficult to expel, while cold air remains at the bottom during heating and is difficult to heat. To address this, a constant temperature structure and control cabinet is proposed, comprising: a cabinet 1 with a door 11 on the front and an internal cavity 12; two air ducts 2 installed on the inner side wall of the cabinet 1, located on both sides of the cabinet 1; a blower component 3 located at the top of the air duct 2; an air inlet valve 4 located on the upper surface of the blower component 3; an air outlet valve 5 located at the top of the air duct 2; a guide component 6 located at the bottom of the air duct 2; and constant temperature components 7 located at the top and bottom of the cabinet 1, respectively.

[0018] In one embodiment, see Figure 4 A partition 13 is fixedly connected to the inner wall of the housing 1, and the partition 13 is located on the side of the air duct 2.

[0019] Specifically, the air inlet valve 4 can control whether the cavity 12 is connected to the air inlet of the blower component 3.

[0020] In one embodiment, see Figure 4 The side surface of the air duct 2 is fixedly connected to the inner wall of the box 1.

[0021] Specifically, the air duct 2 is tightened to isolate the flow of hot and cold air.

[0022] In one embodiment, see Figure 3 The blowing component 3 includes a wind frame 31, a motor 32 and a fan 33. The side surface of the motor 32 is fixedly connected to the inner wall of the wind frame 31, and the output end of the motor 32 is fixedly connected to the fan 33. There are several motors 32 and fans 33, which are distributed in an array inside the wind frame 31.

[0023] Specifically, starting motor 32 can rotate fan 33 to blow air.

[0024] In one embodiment, see Figure 5 The lower surface of the fan frame 31 is fixedly connected to the upper surface of the air duct 2, and the fan 33 faces the upper surface of the air duct 2.

[0025] Specifically, this allows the blower component 3 to blow the air above it downwards.

[0026] In one embodiment, see Figure 3 The air inlet valve 4 is connected to the middle of the air frame 31. The end of the air inlet valve 4 away from the air frame 31 is in contact with the side surface of the partition 13. A sealing ring is provided between the air inlet valve 4 and the partition 13.

[0027] Specifically, the air inlet valve 4 can be selected to decide whether to close the connection between the cavity 12 and the air inlet of the blower component 3, or to close the connection between the air duct 2 and the air inlet of the blower component 3. In conjunction with the air outlet valve 5, it can change the flow path of hot and cold air.

[0028] In one embodiment, see Figure 3 and Figure 4 The air outlet valve 5 is located directly below the air blowing component 3. The end of the air outlet valve 5 away from the air duct 2 is in contact with the inner wall of the air frame 31 away from the cavity 12. A sealing ring is provided between the air outlet valve 5 and the air frame 31.

[0029] Specifically, the air outlet valve 5 can be selected to decide whether to close the connection between the air duct 2 and the air outlet of the blower component 3, or to close the connection between the cavity 12 and the air outlet of the blower component 3. In conjunction with the air inlet valve 4, it can change the flow path of the hot and cold cavities.

[0030] In one embodiment, see Figure 1 and Figure 2The guide component 6 includes a guide rod 61, an arc plate 62, and a baffle 63. The end of the guide rod 61 is fixedly connected to the inner wall of the arc plate 62, and the side surface of the arc plate 62 is movably connected to the inner wall of the housing 1. The end of the baffle 63 is fixedly connected to the side surface of the guide rod 61, and the end of the baffle 63 away from the guide rod 61 is rotatably connected to the lower surface of the air duct 2.

[0031] Specifically, by controlling the air guide rod 61, the angle of the baffle 63 can be changed, thereby determining whether to accelerate the efficiency of air entering the air duct 2 from the cavity 12 or the efficiency of air entering the cavity 12 from the air duct 2. The arc plate 62 can prevent the air inside the device from communicating with the outside of the box 1, thus preventing external debris from entering the device.

[0032] In one embodiment, see Figure 4 The constant temperature component 7 includes a cooling module 71 and a heating module 72, which are fixedly connected to the inner side walls of the upper and lower ends of the housing 1, respectively.

[0033] Specifically, activating the cooling module 71 and the heating module 72 can respectively cool and heat the air inside the cavity 12 to ensure a constant temperature of the air inside the box 1.

[0034] Working principle: During the use of the device, the air inlet valve 4, in conjunction with the partition 13, determines whether to close the connection between the cavity 12 and the air inlet of the blower component 3, or to close the connection between the air duct 2 and the air inlet of the blower component 3. Similarly, the air outlet valve 5, in conjunction with the air frame 31, determines whether to close the connection between the air duct 2 and the air outlet of the blower component 3, or to close the connection between the cavity 12 and the air outlet of the blower component 3. The two work together to control whether the blower component 3 blows the gas inside the air duct 2 into the cavity 12, or blows the gas inside the housing 1 into the air duct 2. During the cooling process, when the cold air settles, it guides the hot air inside the housing 1 to the top of the device through the air duct 2. During the heating process, when the hot air rises, it guides the cold air inside the housing 1 to the bottom of the device through the air duct 2. This ensures uniform cooling and heating of the electronic components and prevents the mixing of hot and cold air with the original air inside the housing, which would lead to uneven cooling and heating.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
