Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving cabinets, and in particular to a thermal management controller suitable for cabinets. Background Art

[0002] As highways become more popular and smarter, many highways are also built in high-altitude areas. In order to coordinate with various electrical equipment on the highways, special cabinets are often installed along the highways. There will be many electronic devices inside to monitor and transmit information on the highway and provide power for various lamps and sound equipment on the highway. The working efficiency of electronic equipment is greatly limited by the ambient temperature. When the ambient temperature is too high or too low, it will affect the working state of the equipment, thereby affecting the effective operation of the entire highway.

[0003] Therefore, a thermal management control cabinet is now set up to adjust the ambient temperature of the electronic equipment. Most temperature control cabinets generally only have fans and other heat dissipation structures inside the counter for heat dissipation. However, the thin air density caused by high altitudes will reduce the heat dissipation effect of electronic equipment, and the equipment will often operate at a reduced rating, which will have a certain impact on the operation of highways. In addition, the temperature difference between day and night in high altitude areas is extremely large. The temperature may be very high during the day, causing the equipment in the cabinet to be unable to work in a good working range. At night, the temperature is too low, which will also cause the equipment in the cabinet to malfunction. These problems are difficult to solve with the heat dissipation structure of conventional temperature control cabinets. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a thermal management controller suitable for a cabinet to solve the problem that the existing cabinet cannot adjust the heat dissipation and heating capacity according to the high altitude environment after installation.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a thermal management controller suitable for a cabinet, comprising a housing, a temperature collector, a heat sink and a processor, wherein the temperature collector, the heat sink and the processor are all installed in the housing, and the temperature collector and the heat sink are both connected to the processor by electrical signals, and further comprising:

[0006] An electric heater, the electric heater is connected to the processor by electrical signals;

[0007] An air pressure detector, which is connected to the processor by electrical signals, and is used to obtain the working altitude data of the cabinet. After determination, the processor can adjust the heat dissipation efficiency of the radiator and the heating efficiency of the electric heater according to the working altitude data;

[0008] The display is connected with the processor by electrical signals.

[0009] The technical principle of the utility model is: the temperature collector can detect the temperature of the cabinet, the air pressure detector can detect the ambient air pressure, and then the processor can know the ambient temperature and the poster height; when the cabinet is located in a high-altitude environment and in a high-temperature environment, the processor can improve the heat dissipation efficiency of the radiator; when the cabinet is located in a high-altitude environment and in a low-temperature environment, the processor can improve the heating efficiency of the electric heater.

[0010] The air pressure detector can work with the processor to control the radiator and electric heater to keep the temperature inside the cabinet at a more suitable state, reduce the impact of the high altitude environment on the temperature environment inside the cabinet, and make the operation of various components in the cabinet better.

[0011] Furthermore, it also includes a refrigerant circulation refrigeration system and a CAN communication circuit for adjusting the refrigeration intensity of the refrigerant circulation refrigeration system. The refrigerant circulation refrigeration system and the CAN communication circuit are both electrically connected to the processor.

[0012] Through the above settings, when the cabinet is located in a high-altitude environment and in a high-temperature environment, the microprocessor controls the start-up of the refrigerant circulation refrigeration system through the CAN communication circuit, and the refrigerant circulation refrigeration system compensates for the heat dissipation of the cabinet to improve the heat dissipation efficiency.

[0013] Furthermore, the radiator is a cooling fan. When the processor controls the electric heater to start, the processor can synchronously control the cooling fan to start.

[0014] Through the above settings, when the cabinet needs to be heated to increase the ambient temperature in a severe cold environment, the microprocessor controls the electric heater to turn on, and at the same time the microprocessor starts the cooling fan, so that the cooling fan drives the air circulation inside the cabinet and improves the heating efficiency inside the cabinet.

[0015] Furthermore, the processor is a microprocessor, and the microprocessor is electrically connected to a power processing circuit which can stabilize the external power supply into a voltage that can be used by the microprocessor.

[0016] Through the above arrangement, the power processing circuit can stabilize the external power supply into a voltage that can be used by the microprocessor circuit, so that the operation of the thermal management controller is more stable.

[0017] Furthermore, the heat dissipation fan is electrically connected to a power PMOS tube for controlling the starting intensity of the heat dissipation fan, and the microprocessor is electrically connected to a PWM output circuit electrically connected to the power PMOS tube.

[0018] Through the above settings, the temperature data measured by the temperature collector is transmitted to the microprocessor, and the microprocessor judges the temperature inside the entire cabinet. When the measured temperature is higher, the microprocessor controls the cooling fan to increase the corresponding speed through the power PMOS tube and the PWM output circuit to improve the heat dissipation efficiency. Otherwise, the speed is reduced or the cooling fan is shut down, so that the speed of the cooling fan is adapted to the temperature, which is more energy-saving and environmentally friendly and has adjustability.

[0019] Furthermore, the microprocessor is electrically connected to an overcurrent protection circuit, the overcurrent protection circuit is provided with a solenoid valve and a solenoid valve drive circuit for protecting the overcurrent protection circuit and the solenoid valve from overload, and the solenoid valve drive circuit is electrically connected to the overcurrent protection circuit.

[0020] Through the above arrangement, the overcurrent protection circuit is used to protect the solenoid valve from overloading, thereby protecting the entire circuit where the microprocessor is located from maintaining normal operation.

[0021] Furthermore, the shell is provided with a plurality of fan output sockets connected to the cooling fan, a temperature sensor plug connected to the temperature collector, a mounting bracket and a plurality of operation buttons for setting the temperature, air pressure and cooling fan parameters. The fan output sockets, temperature sensor plug, mounting bracket and operation buttons are all fixedly mounted on the shell.

[0022] Through the above settings, the housing can protect the temperature collector, radiator, processor, air pressure detector and electric heater to ensure the normal operation of various components.

[0023] Furthermore, it also includes a plurality of signal plugs that can be connected to external devices for information transmission, and the signal plugs are located on the housing.

[0024] Through the above arrangement, the signal plug can provide an interface for the transmission of temperature and air pressure information, making it easier to transmit information.

[0025] Furthermore, the display is fixedly mounted on the shell, and the display is located in the middle of the shell.

[0026] Through the above arrangement, it is possible to more conveniently view the parameter setting process displayed on the display through the middle of the housing, display the temperature of the current measurement point, and view fault information.

[0027] Furthermore, the operation buttons are located at the side of the display, the fan output socket and the temperature sensor plug are located on one side of the shell, and the signal plug is located on the other side of the shell.

[0028] Through the above arrangement, it is easier to evenly distribute the operation buttons, the fan output socket, the temperature sensor plug and the signal plug, and it is also easier to connect the fan output socket, the temperature sensor plug and the signal plug.

[0032] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0033] This embodiment is basically Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a thermal management controller suitable for a cabinet, including an input power supply, a shell 10, a temperature collector, four heat sinks, a processor, an air pressure detector, an electric heater, a display, a plurality of signal plugs 102 that can transmit information to external devices, a refrigerant circulation refrigeration system, and a CAN communication circuit for adjusting the refrigeration intensity of the refrigerant circulation refrigeration system, wherein the display is a display screen 101, the heat sink is a cooling fan, the processor is a microprocessor, the temperature collector, the cooling fan and the processor are all installed in the shell 10, and the temperature collector and the heat sink are both connected to the processor electrical signal.

[0034] like Figure 1 As shown, the housing 10 is provided with a plurality of fan output sockets 103 plugged into the cooling fan, a temperature sensor plug 104 plugged into the temperature collector, a mounting bracket 105 and a plurality of operation buttons 106 for setting the temperature, air pressure and cooling fan parameters. The display screen 101, the signal plug 102, the fan output socket 103, the temperature sensor plug 104, the mounting bracket 105 and the operation button 106 are all fixedly mounted on the housing 10; the display is located in the middle of the surface of the housing 10, the operation button 106 is located at the right side of the display, the fan output socket 103 and the temperature sensor plug 104 are located on the upper side of the housing 10, the signal plug 102 is located on the lower side of the housing 10, and the mounting bracket 105 is located on the left side of the housing 10.

[0035] like Figure 2As shown, the microprocessor is electrically connected to a power processing circuit that can stabilize the external power supply into a voltage that can be used by the microprocessor, and the power processing circuit is electrically connected to the input power supply; the air pressure detector, the electric heater, the display, the refrigerant circulation refrigeration system and the CAN communication circuit are all connected to the processor electrical signal, the air pressure detector is used to obtain the working altitude data of the cabinet, and the processor can adjust the heat dissipation efficiency of the radiator and the heating efficiency of the electric heater according to the working altitude data after determination; the CAN communication circuit is electrically connected to the power processing circuit;

[0036] like Figure 2 As shown, the cooling fan is electrically connected to a power PMOS tube for controlling the starting intensity of the cooling fan, the microprocessor is electrically connected to a PWM output circuit electrically connected to the power PMOS tube, and the power PMOS tube is electrically connected to the input power supply.

[0037] In addition, when the processor controls the electric heater to start, the processor can synchronously control the cooling fan to start.

[0038] When a thermal management controller suitable for a cabinet in this embodiment is used, the housing 10 is first stably installed through the mounting bracket 105 of the housing 10. After the installation is completed, the temperature, air pressure and cooling fan parameters in the microprocessor are preset and input can be made at the operation button 106.

[0039] When the thermal management controller is in use, the housing 10 can protect the input power supply, temperature collector, radiator, processor, air pressure detector, electric heater, display, signal plug 102, refrigerant circulation refrigeration system and CAN communication circuit structure, allowing the various structures to operate normally.

[0040] During the operation of the thermal management controller, the temperature collector can detect the temperature of the cabinet. The temperature data measured by the temperature collector is transmitted to the microprocessor, and the microprocessor determines the temperature inside the entire cabinet. When the current temperature measured by one of the temperature collectors is greater than or equal to 40°C, the cooling fan is controlled to rotate at a corresponding speed through the power PMOS tube and the PWM output circuit. The default temperature range of the speed regulation range is 40°C-60°C. When the measured temperature exceeds 40°C, the temperature rises and the cooling fan speed will also increase. When the temperature is ≥60°C, the cooling fan becomes full speed. When the temperature drops to ≤27°C, the cooling fan is at the minimum speed / or the cooling fan is turned off.

[0041] When the air pressure detector measures that the cabinet is located in a high altitude environment and in a high temperature environment, the microprocessor controls the start of the refrigerant circulation refrigeration system through the CAN communication circuit. The refrigerant circulation refrigeration system compensates for the heat dissipation of the cabinet. When the temperature is ≥60℃, the cooling fan becomes full speed. At the same time, the air pressure sensor feedback is high altitude. The CAN communication circuit starts the refrigerant circulation refrigeration system to compensate for the heat dissipation. When the temperature drops to ≤27℃, the cooling fan is adjusted to run at a low speed, and the refrigerant circulation refrigeration system is shut down through the CAN communication circuit.

[0042] When the cabinet needs to be heated to increase the ambient temperature in a severely cold environment, the microprocessor controls the electric heater to turn on, and at the same time, the microprocessor starts the cooling fan, so that the cooling fan drives the air circulation inside the cabinet to keep the cabinet within a suitable temperature range; the cooling fan still adjusts the rotation frequency through the power PMOS tube and the PWM output circuit, and the fan speed regulation method is that the PWM output circuit controlled by the microprocessor circuit controls the frequency of the power PMOS tube of the fan; when the air pressure detector measures that the cabinet is located in a high altitude environment and in a low temperature environment, the microprocessor controls the electric heater to increase its heating intensity, so that the temperature inside the cabinet can be further rapidly increased.

[0043] In the above process, the overcurrent protection circuit is used to protect the solenoid valve from overloading, thereby protecting the entire circuit where the microprocessor is located from maintaining normal operation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
