[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0028] Please refer to Figure 1 and Figure 2 A transport sub-low temperature device 100 includes an insulating box 11, a control component and a temperature control component; wherein the insulating box 11 includes a built-in isolation member 113, the isolation member 113 divides the internal space of the insulating box 11 into a first isolation chamber and a second isolation chamber 112, the second isolation chamber 112 is close to the placement plane of the insulating box 11, the control component is arranged in the first isolation chamber, the control component includes a power supply 12, the temperature control component is arranged in the second isolation chamber 112, the temperature control component includes a heat exchange module 14 and a solenoid valve module 15, the heat exchange module 14 is connected to the solenoid valve module 15, and the control component is electrically connected to the solenoid valve module 15.

[0029] The transport sub-low temperature device 100 is mainly used to provide a sub-low temperature environment. In order to preserve items that require low-temperature storage conditions, an insulating box 11 is provided that is made of insulating materials, such as rubber, silicone, plastic and the like. The insulating box 11 is used to prevent the leakage of electrical energy from the internal circuit, thereby protecting the safety of the user from the outside. At the same time, the isolation member 113 built into the insulating box 11 and the inner wall of the insulating box 11 enclose a first isolation chamber and a second isolation chamber 112, which can effectively isolate and protect the control component and the thermostat component. The heat exchange module 14 in the thermostat component is used to provide a cold source for creating a sub-low temperature environment, which includes a heat exchanger. During use, the heat exchanger causes the water vapor in the air to liquefy due to the heat transfer of the internal contacts, generating condensed water. The isolation member 113 effectively isolates the control component and the thermostat component, making it difficult for the condensed water to contact the internal circuit of the control component, thereby achieving water and electricity isolation of the transport sub-low temperature device 100 and improving the safety of the transport sub-low temperature device 100.

[0030] Furthermore, the control assembly is located within the first isolation chamber, ensuring it operates in a stable temperature environment. Excessively low temperatures can cause changes in resistance within the circuit. The resistance of semiconductors may increase as temperature decreases, and this resistance change may affect the normal operation of the circuit. Other electronic components within the control assembly may also experience performance degradation at extremely low temperatures. For example, the performance of components such as capacitors and inductors may decline, leading to reduced overall circuit performance.

[0031] It is conceivable that the circuits within the control assembly generate heat during operation. If this heat is transferred to the heat exchange module 14 of the thermostat assembly, it will affect the cooling effect of the heat exchange module 14. Therefore, the control assembly and the thermostat assembly are respectively disposed in the first and second isolation chambers 112 to ensure the cooling effect of the heat exchange module 14.

[0032] In this embodiment, the control assembly includes a control mainboard 13 electrically connected to a power source 12. A through-hole is defined in an isolator 113 for passing connecting wires between the solenoid valve module 15 and the control mainboard 13. A sealant can be provided around the perimeter of the through-hole, tightly engaging the connecting wires from the periphery. While providing a seal, the isolator 113 also ensures electrical connectivity between the control assembly and the solenoid valve module 15 via the connecting wires. Using connecting wires allows the control mainboard 13 to more precisely control the solenoid valve module 15 and achieve faster signal transmission rates.

[0033] In another embodiment, the control mainboard 13 and the solenoid valve module 15 can be wirelessly connected. The wireless connection can be in the form of a Wi-Fi connection, using a Wi-Fi module to establish a wireless communication connection between the control mainboard 13 and the solenoid valve, and realize data transmission and control instruction transmission through a router or direct connection; a Bluetooth connection, using a Bluetooth module to realize a short-range wireless connection between the control mainboard 13 and the solenoid valve, and control instructions can be sent through a mobile phone app or other Bluetooth device; a Zigbee connection, Zigbee is a low-power, short-range wireless communication protocol that can be used for data transmission and control signal transmission between the control mainboard 13 and the solenoid valve; a LoRa connection, LoRa is a long-distance, low-power Internet of Things communication technology that can be used for remote communication between the control mainboard 13 and the solenoid valve; an RF connection, a radio frequency communication module can realize a wireless connection between the control mainboard 13 and the solenoid valve, and is suitable for data transmission and control within a certain distance. This allows the control mainboard 13 to control the solenoid valve module 15 even without opening a hole in the isolation member 113.

[0034] Please refer to Figure 2 In this embodiment, the temperature control assembly includes a circulating water module, which includes a water pump 16, a water tank 17, and a refrigeration element 19. The water pump 16 is electrically connected to the control motherboard 13. The water pump 16, the water tank 17, the solenoid valve module 15, and the refrigeration element 19 are connected to form a circulation loop. The water pump 16 is used to drive the circulating water to flow in the circulation loop, and the solenoid valve module 15 is used to change the on / off state of the circulation loop. The refrigeration element 19 is located outside the second isolation chamber 112 and has a sub-low temperature area. The refrigeration element 19 can be a transfer box for storing items requiring sub-low temperature storage. The refrigeration element 19 can also be an application-oriented device such as a cold cap or cold blanket, used to provide sub-low temperature refrigerant for users requiring sub-low temperature treatment.

[0035] Among them, the water pump 16 provides a power source for the water tank 17, and introduces the circulating water in the water tank 17 into the solenoid valve module 15. The solenoid valve module 15 controls the circulating water to enter the heat exchange module 14 and the refrigeration component 19. The solenoid valve is connected to the circulating water module, and the flow rate of the fluid is controlled by the opening state of the solenoid valve.

[0036] The heat exchange module 14 also includes a compressor connected to the heat exchanger. When the temperature of the sub-low temperature area of the refrigeration component 19 is too low, the compressor can compress the built-in condensate, thereby compressing the gaseous condensate into a liquid state. The liquefaction of the condensate will release heat, and the heat will be transferred to the circulating water through the heat exchanger, causing the circulating water connected to the refrigeration component 19 to heat up, realizing the heating function of the transfer sub-low temperature device 100 and maintaining the sub-low temperature of the refrigeration component 19.

[0037] When the temperature of the sub-low temperature area of the refrigeration component 19 is too high, the compressor stops compression and the liquid condensate vaporizes. The vaporization causes the condensate to absorb heat. The heat is transferred through the heat exchanger, and the temperature of the circulating water decreases, causing the temperature of the sub-low temperature area of the refrigeration component 19 to decrease.

[0038] Specifically, the solenoid valve module 15 includes a first solenoid valve 151 and a second solenoid valve 152. The first solenoid valve 151 is provided with a first interface, a second interface and a third interface. The first interface is connected to the water tank, the second interface is connected to the water pump 16, and the third interface is connected to the refrigeration component 19. The second solenoid valve 152 is provided with a fourth interface, a fifth interface and a sixth interface. The fourth interface is connected to the water tank, the fifth interface is connected to the water pump 16, and the sixth interface is connected to the heat exchange module 14. The heat exchange module 14 is connected to the refrigeration component 19.

[0039] Please refer to Figure 3 The sub-low temperature transfer device 100 has a liquid discharge state and a liquid return state. When the sub-low temperature transfer device 100 is in the liquid discharge state, the first interface and the second interface are connected in the first solenoid valve 151, and the fifth interface and the sixth interface are connected in the second solenoid valve 152. The water pump 16 drives the circulating water from the water tank into the refrigeration element 19. At this time, the circulating water passes through the first solenoid valve 151, the water pump 16, the second solenoid valve 152, and the heat exchange module 14 in sequence from the water tank to the refrigeration element 19. The circulating water, after being changed in temperature by the heat exchange module 14, reaches the sub-low temperature area of the refrigeration element 19 for sub-low temperature treatment.

[0040] When the sub-low-temperature transfer device 100 is in the liquid return state, the first interface and the third interface are connected within the first solenoid valve 151, and the fifth interface and the fourth interface are connected within the second solenoid valve 152. The water pump 16 drives the circulating water from the refrigeration element 19 into the water tank. The temperature of the circulating water in the refrigeration element 19 changes. The circulating water passes from the refrigeration element 19 through the first solenoid valve 151, the water pump 16, and the second solenoid valve 152 in sequence to reach the water tank, completing one cycle of the circulating water. The sub-low-temperature transfer device 100 enters the liquid discharge state again, achieving continuous cooling of the circulating water.

[0041] By controlling the internal on / off circuits of the first and second solenoid valves 151, 152 via the control mainboard 13, the circulating water flow rate can be regulated. Faster circulating water flow can more quickly remove the temperature from the sub-low temperature region of the refrigeration element 19. By independently controlling the flow of circulating water within the heat exchanger via the second solenoid valve 152, the refrigeration efficiency and sub-low temperature of the sub-low temperature transfer device 100 can be precisely controlled.

[0042] The combination of a circulating water module, a water pump 16, a water tank 17, and a refrigeration unit 19 enables precise temperature control of specific areas. The water pump 16 circulates water through electrical connections, while the refrigeration unit 19 provides the required cooling effect within the sub-low temperature region, thereby achieving precise temperature control. Using the solenoid valve module 15 to control the connection between the water pump 16, the water tank 17, and the refrigeration unit 19 effectively regulates energy consumption and improves the system's energy efficiency, thereby achieving energy-saving and high-efficiency results. Furthermore, the refrigeration unit 19, located outside the second isolation chamber 112, may help reduce the impact of the internal temperatures of the first and second isolation chambers 112, thereby improving the stability of temperature control.

[0043] To facilitate the replenishment of water to the water tank 17, the insulating box 11 is provided with a water inlet chamber 1121 on one side of the second isolation chamber 112. The water inlet chamber 1121 is provided with an opening. The water tank 17 is partially provided in the water inlet chamber 1121 and blocks the opening. The water inlet 171 of the water tank 17 is exposed at the opening. Since the transport sub-low temperature device 100 needs to be moved and used separately, the water tank 17 serves to temporarily store water, so the water tank 17 needs to be replenished with water regularly. The provision of the water inlet chamber 1121 with an opening allows the water tank 17 to be replenished with water without opening the second isolation chamber 112. At the same time, the water tank 17 maintains the blockage of the water inlet chamber 1121 to prevent foreign matter from entering the second isolation chamber 112.

[0044] Please refer to Figure 1In this embodiment, the control assembly further includes an operation panel 18, which is located on the top surface of the insulating box 11. The operation panel 18 includes a display screen 181, which is electrically connected to the control main board 13. The display screen 181 can display the operating status of various components of the thermostat assembly and the control assembly, such as the open and closed status of the thermostat assembly's heat exchanger, water pump 16, compressor, first solenoid valve, and second solenoid valve. The display screen 181 can also display the specific temperature of the sub-low temperature region of the refrigeration element 19. The refrigeration element 19 can be provided with a temperature sensor to detect the specific temperature of the sub-low temperature region and transmit it to the display screen 181, visually displaying the temperature and facilitating user observation and real-time control.

[0045] Furthermore, the operation panel 18 is provided with a plurality of buttons 182, each of which is electrically connected to the control mainboard 13. Each button 182 is electrically connected to each component of the thermostat assembly in a one-to-one correspondence. The control mainboard 13 of the control assembly can control the individual operating states of each component within the thermostat assembly, such as the opening and closing of the water pump 16, the opening and closing of the first solenoid valve and the second solenoid valve, etc. Through the connection between the buttons 182 and the control mainboard 13, the operating states of each component can be individually controlled by the buttons 182. The simple and intuitive form of the buttons 182, combined with the status display and temperature display effects of the display screen 181, reduces the user's learning cost and improves the user's operating efficiency.

[0046] In this embodiment, the operation panel 18 is detachably connected to the wall of the first isolation chamber, facilitating user access to the control components within the first isolation chamber. The first and second isolation chambers 112 are detachably connected, with isolation members 113 mounted on the walls of either the first or second isolation chambers 112, facilitating maintenance and repair of large components such as the water pump 16, water tank 17, and heat exchange module 14.

[0047] Furthermore, the operation panel 18 and the first isolation chamber can be arranged in a rotationally connected form. The first isolation chamber is provided with a control component, the control mainboard 13 and the power supply 12 are relatively light in weight, and the cavity walls of the first isolation chamber and the second isolation chamber 112 are rotatably connected.

[0048] To improve the efficiency of heat transfer within heat exchange module 14, it includes a heat exchanger and a radiator. The heat exchanger and radiator are positioned in close proximity, and the walls of the first isolation chamber are provided with heat dissipation holes for connecting the radiator to the outside world. This close proximity between the heat exchanger and radiator effectively increases the contact area between them, thereby improving heat transfer efficiency. This helps accelerate the heat exchange process and enhance the system's heat dissipation.

[0049] The heat dissipation holes in the wall of the first isolation chamber allow the radiator to communicate with the outside world, facilitating the introduction of external air and promoting ventilation within the radiator, thereby improving the heat dissipation effect. By enhancing the heat dissipation effect and improving heat dissipation and ventilation, the temperature within the heat exchange module 14 can be effectively reduced, the heat exchange efficiency can be improved, and thus better heat transfer can be achieved.

[0050] In another embodiment, the isolation member 113 includes a main board and at least four sheet metal members, each of which is installed at opposite ends of the main board. Each sheet metal member has a bottom plate, a side baffle perpendicular to the bottom plate, and a connecting baffle to enclose a mounting groove for installing the main board. Each sheet metal member is detachably connected to the cavity wall of the first isolation cavity or the cavity wall of the second isolation cavity.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
