Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more specifically to a constant temperature control system for refrigeration equipment. Background Technology

[0002] Some foods or medicines need to be stored in specific low-temperature ranges, typically using refrigeration equipment such as cold storage or refrigerators. Existing cold storage or refrigerators use electric compressors to drive refrigerant to lower the temperature, shutting off the compressor when a specific temperature is reached. This refrigeration method relies on electricity; a power outage would result in significant economic losses. Furthermore, for larger cold storage facilities, the temperature control response is too slow. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a constant temperature control system for refrigeration equipment, which can extend the duration of constant temperature control and more accurately regulate the temperature inside the refrigeration equipment.

[0004] The present invention provides a technical solution: a constant temperature control system for refrigeration equipment, comprising: a temperature control chamber, a temperature control medium, and a temperature sensor. The temperature control medium is placed inside the temperature control chamber. The outer wall of the temperature control chamber is covered with an insulation layer. The temperature control chamber is divided into multiple independent chambers. Each chamber is provided with a convection hole and a cover plate for controlling the opening and closing of the convection hole. A control mechanism is provided on the temperature control chamber corresponding to the cover plate. The control mechanism is electrically connected to the temperature sensor.

[0005] The beneficial effects of the above technical solution are as follows: the temperature control medium can store energy at low temperatures and release energy when the temperature rises to lower the temperature back to the set value. Multiple independent chambers within the control cabinet can provide different temperature control capabilities depending on the number of chambers opened. This allows the temperature control cabinet to close some chambers when there is less demand for temperature control, resulting in a longer-lasting temperature control capability and providing extended temperature protection for the refrigeration equipment, preventing items inside the equipment from failing due to temperature increases.

[0006] Furthermore, the temperature control medium includes a temperature control housing and a metal-mixed phase change liquid disposed within the temperature control housing. The metal-mixed phase change liquid can maintain the temperature within a certain range through phase change, thereby achieving the purpose of temperature control.

[0007] Furthermore, the temperature control chamber is equipped with a mounting bracket for placing the temperature control medium, and convection holes are provided on both the front and back of the temperature control chamber. These convection holes penetrating the temperature control chamber increase the efficiency and speed of heat exchange between the air and the temperature control medium within the refrigeration equipment, thereby enabling the temperature control chamber to quickly regulate the temperature within the refrigeration equipment.

[0008] Furthermore, the cover plate is rotatably connected to the temperature control box body, and multiple convection holes are opened from top to bottom on the same side of the box body. Each convection hole is a horizontal strip hole, and each convection hole corresponds to a cover plate.

[0009] Furthermore, a sector gear is provided at the tail end of the cover plate, and the control mechanism includes a rack meshing with the sector gear. The rack is fixedly mounted on an adjusting rod, which is controlled by a lead screw and nut assembly at its end, which is driven by a stepper motor. The opening and closing of the cover plate can be controlled by raising and lowering the adjusting rod.

[0010] Furthermore, the insulation layer includes an insulation board and a waterproof cloth, with the insulation board closely attached to the temperature control box and the waterproof cloth covering the outside of the insulation board.

[0011] Furthermore, the cover of each chamber is controlled by a different adjusting rod, and these rods are independent of each other. This allows for the selection of a specific number and location of convection holes for opening and closing.

[0012] Furthermore, the temperature control chamber is provided with a sealed pipe corresponding to the control mechanism, and the sealed pipe is provided with a clearance notch corresponding to the sector gear. A flexible sealing mechanism is also provided within the clearance notch. The sealed pipe can ensure the normal operation of the control mechanism. Attached Figure Description

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0022] like Figure 1-5 As shown, this embodiment provides a constant temperature control system for refrigeration equipment, including: a temperature control chamber 200, a temperature control medium 510, and a temperature sensor. The temperature control medium 510 is placed inside the temperature control chamber 200. The outer wall of the temperature control chamber 200 is covered with a heat insulation layer. The temperature control chamber 200 is divided into multiple independent chambers. Each chamber is provided with a convection hole 210 and a cover plate 300 for controlling the opening and closing of the convection hole 210. A control mechanism is provided on the temperature control chamber 200 corresponding to the cover plate 300. The control mechanism is electrically connected to the temperature sensor.

[0023] The temperature control medium 510 can store energy at low temperatures and release energy when the temperature rises to lower the temperature back to the set value. Multiple independent chambers within the control cabinet can provide different temperature control capabilities depending on the number of chambers opened. This allows the temperature control cabinet 200 to close some chambers when temperature control requirements are low, resulting in longer-lasting temperature control and providing extended temperature protection for the refrigeration equipment, preventing items inside from failing due to temperature increases.

[0024] To control the temperature within the refrigeration equipment within a certain range, the temperature control medium 510 includes a temperature control housing and a metal-mixed phase change liquid disposed within the temperature control housing. The metal-mixed phase change liquid can maintain the temperature within a certain range through phase change, thereby achieving the purpose of temperature control.

[0025] To secure the temperature control medium 510, a mounting bracket 500 for placing the temperature control medium 510 is provided inside the temperature control housing 200. Convection holes 210 are provided on both the front and back of the temperature control housing 200. The convection holes 210 penetrating the temperature control housing 200 increase the efficiency and speed of heat exchange between the air and the temperature control medium 510 within the refrigeration equipment, thereby enabling the temperature control housing 200 to rapidly regulate the temperature within the refrigeration equipment.

[0026] The cover plate 300 is rotatably connected to the temperature control chamber 200. Multiple convection holes 210 are formed from top to bottom on the same side of the chamber. Each convection hole 210 is a transverse strip-shaped hole, and each convection hole 210 corresponds to a cover plate 300. Furthermore, a sector gear 310 is provided at the tail end of the cover plate 300. The control mechanism includes a rack meshing with the sector gear 310. The rack is fixedly mounted on an adjusting rod 410, which is controlled by a lead screw and nut pair at its end, driven by a stepper motor 400. The opening and closing of the cover plate 300 can be controlled by raising and lowering the adjusting rod 410. Each chamber's cover plate 300 is controlled by a different adjusting rod 410, and these different adjusting rods 410 are independent of each other. This allows for the selection of a specific number and position of the convection holes 210 for opening and closing.

[0027] As a further improvement, the temperature control chamber 200 is provided with a sealed pipe 220 corresponding to the control mechanism. The sealed pipe 220 is provided with a clearance notch corresponding to the sector gear 310, and a flexible sealing mechanism is also provided within the clearance notch. The sealed pipe 220 can ensure the normal operation of the control mechanism.

[0028] In a preferred embodiment, the insulation layer includes an insulation board and a waterproof cloth, the insulation board being in close contact with the temperature control box 200, and the waterproof cloth covering the outside of the insulation board.
