Description

Technical Field

[0001] This utility model relates to the field of environmental temperature control technology, and in particular to an environmental temperature control device that can be used alone or in conjunction with other insulated boxes. Background Technology

[0002] With increasing product quality requirements and shorter R&D cycles, testing needs are growing, often requiring multiple sets of temperature simulation tests under different conditions or for different products to be conducted in parallel. Currently, the industry generally adopts a solution of configuring an independent environmental test chamber for each test unit. That is, each test chamber is a completely independent system, equipped with its own complete temperature control system, including a compressor, condenser, evaporator, heater, circulating fan, refrigerant piping, and an independent control system.

[0003] Currently, high and low temperature testing of products generally adopts the traditional "one chamber, one system" model, where each independent test chamber has its own complete temperature control system (including compressors, heaters, fans, etc.). This model results in significant redundancy of core temperature control components within each chamber, leading to high equipment costs, enormous energy consumption, and a substantial increase in floor space. Furthermore, the coexistence of multiple independent systems complicates maintenance, and the fixed installation of each chamber prevents flexible configuration according to testing needs, resulting in low overall utilization efficiency and flexibility. Therefore, a centralized temperature control solution is urgently needed to address the cost, energy consumption, and flexibility issues caused by system redundancy. Summary of the Invention

[0004] This invention proposes an environmental temperature control device, which aims to solve the problems of cost, energy consumption and flexibility caused by existing system redundancy.

[0005] This utility model provides an ambient temperature control device, comprising: a control box, which houses an insulated box, a temperature regulating component, a supply fan, a circulation fan, and electrical control equipment; at least one supply air valve and at least one return air valve are provided on the exterior of the control box; the outlet of the supply fan is connected to the supply air valve and the supply air duct of the insulated box respectively; the inlet of the circulation fan is connected to the return air valve and the return air duct of the insulated box respectively; and the electrical control equipment is connected to the supply fan, the circulation fan, the supply air valve, the return air valve, and the temperature regulating component respectively.

[0006] Specifically, this invention incorporates a temperature regulation component and multiple external air valve interfaces within the control box. External insulated boxes are connected to the temperature control box via air ducts, enabling temperature control within the external insulated boxes. This effectively addresses the inherent shortcomings of the traditional "one chamber, one system" approach. Furthermore, the control box itself contains an insulated box, allowing it to be used independently for temperature control. Therefore, this device can be used independently, is easily movable, and quickly integrated with multiple external insulated boxes to form a centralized temperature control system, significantly reducing equipment costs, energy consumption, and floor space. Its electrical control system automatically manages the air valves and temperature control process, achieving convenient operation, high reliability, and strong scalability, perfectly adapting to the complex requirements of multi-task parallel testing.

[0007] Furthermore, the number of supply air valves and return air valves are set accordingly; and the supply air valves are connected to the air outlet of the external insulation box through the supply air insulation duct; the return air valves are connected to the return air outlet of the external insulation box through the return air insulation duct.

[0008] Furthermore, quick-release clamps are provided at the interfaces of the supply air valve and the return air valve.

[0009] Furthermore, an AGV mobile vehicle is installed at the bottom of the control box.

[0010] Furthermore, the temperature control assembly includes a refrigeration unit, a heater, a refrigeration evaporator, and a liquid nitrogen injector, and the refrigeration unit, heater, refrigeration evaporator, and liquid nitrogen injector are respectively connected to electrical control equipment.

[0011] Furthermore, temperature sensors are installed in both the insulation box body and the external insulation box, and the temperature sensors are connected to the electrical control equipment.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention, by incorporating a temperature regulation component and multiple external air valve interfaces within a control box, connects external insulated boxes to the temperature control box via air ducts. This allows for temperature control within the external insulated boxes, effectively addressing the inherent shortcomings of the traditional "one-box-one-system" approach. Furthermore, the control box itself contains an insulated box, allowing it to be used independently for temperature control. Therefore, the device can be used independently or flexibly moved to quickly connect with multiple external insulated boxes to form a centralized temperature control system, significantly reducing equipment costs, energy consumption, and floor space. Its electrical control equipment automatically manages the air valves and temperature control process, achieving convenient operation, high reliability, and strong scalability, perfectly adapting to the complex requirements of multi-task parallel testing. Additionally, the inclusion of an AGV mobile vehicle and air valve interfaces with quick-release clamps enables flexible movement and rapid connection with multiple external insulated boxes, greatly improving deployment flexibility and site utilization.

Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0019] This utility model provides an environmental temperature control device, such as... Figures 1 to 2As shown, this utility model provides an ambient temperature control device, including: a control box, inside which are installed an insulated box 4, a temperature regulating component, a supply fan 5, a circulating fan 6, and an electrical control device 7; at least one supply air valve 2 and at least one return air valve 1 are provided on the outside of the control box; the outlet of the supply air fan 5 is connected to the supply air valve 2 and the air supply duct of the insulated box 4 respectively; the inlet of the circulating fan 6 is connected to the return air valve 1 and the return air duct of the insulated box 4 respectively; the electrical control device 7 is connected to the supply air fan 5, the circulating fan 6, the supply air valve 2, the return air valve 1, and the temperature regulating component respectively.

[0020] In this way, by incorporating a temperature regulation component and multiple external air valve interfaces within the control box, and connecting the external insulated boxes to the temperature control box via air ducts, the temperature inside the external insulated boxes can be controlled. This effectively solves the inherent defects of the traditional "one chamber, one system" model. Furthermore, the control box also includes an insulated box 4, which can be used independently for temperature control. Therefore, this device can be used independently, is easily movable, and quickly integrated with multiple external insulated boxes to form a centralized temperature control system, significantly reducing equipment costs, energy consumption, and floor space. Its electrical control equipment 7 automatically manages the air valves and temperature control process, achieving convenient operation, high reliability, and strong scalability, perfectly adapting to the complex requirements of multi-task parallel testing.

[0022] Specifically, quick-release clamps are provided at the interfaces of the supply air valve 2 and the return air valve 1; in this way, the supply air valve 2 and the return air valve 1 can be quickly connected to the external insulation box through the quick-release clamps. The quick-release clamps are mechanical connection devices that can realize quick assembly and disassembly between the air duct and the valve interface and ensure the sealing and stability after connection, such as, but not limited to, cam-type quick-release handles, spiral buckle connectors or pneumatic locking mechanisms.

[0023] Specifically, an AGV mobile vehicle 3 is installed at the bottom of the control box. In this way, the control box moves the equipment to the location connected to the external insulated box through the controller of the AGV mobile vehicle 3. The AGV mobile vehicle 3 is connected to the controller and the controller controls the movement of the AGV mobile vehicle 3, which are existing technologies and will not be described in detail here.

[0024] Specifically, the temperature control assembly includes a refrigeration unit 8, a heater 9, a refrigeration evaporator 10, and a liquid nitrogen injector 11, and the refrigeration unit 8, the heater 9, the refrigeration evaporator 10, and the liquid nitrogen injector 11 are respectively connected to the electrical control equipment 7.

[0027] In this way, the temperature sensors inside the insulation box 4 and the external insulation box are connected to the electrical control device 7 for temperature feedback. Then, the temperature value is set, and the supply fan 5 and the circulating fan 6 are started. The supply fan 5 can control its air volume according to actual needs. Based on the set temperature, the refrigeration unit 8 and the heater 9 are started to heat and cool the equipment's own insulation box 4 and the connected insulation boxes. The output power of the refrigeration unit 8 and the heater 9 is controlled by the electrical control device 7 to finally reach the set temperature and stabilize it. At the same time, a liquid nitrogen injector 11 is also installed inside the circulating air duct 12. If the equipment's refrigeration unit 8 fails or the cooling rate does not meet the requirements, a liquid nitrogen source can be connected for auxiliary cooling.

[0028] Implementation Process: During use, the control box is moved to the position connected to the external insulation box via the controller of the AGV mobile vehicle 3. One end of the supply air insulation duct is connected to the supply air valve 2 via a quick-release clamp, and the other end is connected to the air outlet of the insulation box. One end of the return air insulation duct is connected to the return air valve 1 via a quick-release clamp, and the other end is connected to the return air outlet of the insulation box. Connect the ducts according to the number of ducts required by the external insulation box. Start the supply air fan 5, circulating fan 6, refrigeration unit 8, and heater 9 via the electrical control equipment 7. Open the return air valve 1 and supply air valve 2 connected to the ducts, and keep the valves not connected to the ducts closed. 4. The temperature sensor inside the external insulation box is connected to the electrical control device 7 for temperature feedback. Then, the temperature value is set, and the supply fan 5 and the circulation fan 6 are started. The supply fan 5 can control its air volume according to actual needs. According to the set temperature, the refrigeration unit 8 and the heater 9 are started to heat and cool the equipment's own insulation box 4 and the connected insulation boxes. The output power of the refrigeration unit 8 and the heater 9 is controlled by the electrical control device 7 to finally reach the set temperature and stabilize it. At the same time, a liquid nitrogen injector 11 is also installed inside the circulation air duct 12. If the equipment's refrigeration unit 8 fails or the cooling rate does not meet the requirements, a liquid nitrogen source can be connected for auxiliary cooling.
