Therefore, the heat dissipation of the equipment to be dissipated is realized by combining the water cooling device and the air cooling device, the defects caused by a single heat dissipation mode can be overcome, the heat dissipation efficiency is improved, the damage to components of the equipment to be dissipated, caused by low heat dissipation efficiency of the single heat dissipation mode, is avoided, and the guarantee is provided for the normal work of the equipment to be dissipated.
Wherein, the device to be cooled can be a frequency converter.
Considering that some wait in the heat dissipation equipment, components and parts distribute unevenly and calorific capacity of all kinds of components and parts is different, in order to can realize the heat dissipation to waiting heat dissipation equipment in the work high-efficiently, wait that heat dissipation equipment can set up a plurality of heat dissipation regions, correspondingly, combined cooling system's water cooling plant can include water pump, water tank and a set of water circulation pipeline or at least two sets of water circulation pipeline that connect in parallel. The setting position of each group of water circulation pipelines corresponds to each heat dissipation area of the equipment to be cooled one by one, namely, each heat dissipation area is provided with a water circulation pipeline.

One end of the resistor R1 is connected with a power supply, the other end is connected with the thermistor, and when the temperature of the component in the heat dissipation area rises, the thermistor Rt1 decreases. Because the power supply is a constant current source, the partial voltage of Rt1 becomes small, the partial voltage of resistor R1 becomes high, the temperature detection signal becomes strong, and when the internal temperature of the equipment to be cooled is reduced, the detection signal is weak.
Comparator N1 is modeled as LM931 and is responsible for making a differential comparison of the user-specified temperature and the first temperature detected.
The temperature setting circuit 3002 may include a resistor R2, a capacitor C1, and a potentiometer RW1, wherein the resistor R2 may have a resistance of 95 kilo-ohms, the potentiometer may be selected to have a type 3296W, a nominal resistance range of 10 Ω -2M Ω, and a capacitor may be selected to have a value of 500 pF. The comparator N1 has the same direction input end connected to the thermistor Rt1, the reverse end connected to one end of the resistor R2, the capacitor C1 and the potentiometer RW1, the other end of the potentiometer RW1 connected to the power source VCC, and the resistor R2 and the capacitor C1 are grounded.
The switching circuit 3003 may include a relay KA1, a transistor Q1, a resistor R3, a resistor R4, and a freewheeling diode D1. The base of the triode Q1 is connected with one end of a resistor R3 and one end of a resistor R4, the other end of the resistor R3 is connected with the output end of a comparator N1, and the other end of the resistor R4 is connected with the emitter of the triode Q1 and grounded. One end of the relay KA1 is connected with a collector of the triode Q1, base current is amplified and then is supplied to the relay KA1, the other end of the electromagnetic relay KA1 is connected with a power supply VCC, the fly-wheel diode D1 is connected with the electromagnetic relay KA1 in parallel and plays a protection role, the anode of the fly-wheel diode D1 is connected with the collector of the triode Q1, and the cathode of the fly-wheel diode D1 is connected with the power supply VCC. In implementation, the resistance of the resistor R3 may be 2K Ω, the resistance of the resistor R4 may be 0.8K Ω, the model of the electromagnetic relay KA1 may be GMY2N-J, the model of the freewheeling diode D1 is FR105, the model of the triode Q1 is an NPN-type triode, the model of the Q1 may be 2SC4019, and the conduction voltage of the Q1 is 0.7V.
In order to further realize efficient heat dissipation in the heat dissipation area when the control module is used to control the opening of the control valve, in some embodiments, as shown in fig. 4, the control module may further include a step-up circuit 3004, where the step-up circuit 3004 is disposed between the switch circuit 3003 and the control valve, and is configured to control the opening degree of the control valve according to the area temperature of the heat dissipation area where the corresponding water circulation pipeline is located after the switch circuit 3003 controls the opening of the control valve.
In practice, the pacing circuit 3004 may include a thermistor Rt3 connected to a resistor R5, the type of the thermistor Rt3 may be MF 5110K 3950, and the resistance of the resistor R5 may be 1K Ω. In operation, after the control valve is opened, the step-adjusting circuit 3004 may detect the temperature of the heat dissipation area where the corresponding water circulation pipe is located, and control the opening of the control valve according to the detected temperature of the area.
When the control valve is an electronic expansion valve, the basic opening step number of the electronic expansion valve can be set to be 60 steps, and after the step-adjusting circuit starts to work, the corresponding step number of the electronic expansion valve is increased by 10 steps when the detected temperature is increased by one degree, so as to control the water flow size and speed.
In order to ensure the high efficiency of heat dissipation, the third threshold value may be set to a temperature value at which the opening degree of the control valve reaches the maximum. Therefore, when the opening degree of the control valve is the largest, namely the temperature of the area corresponding to the heat dissipation area reaches the third threshold value, the detection control device can control the air cooling device to conduct air exhaust heat dissipation so as to accelerate heat dissipation.
In some embodiments, the air-cooling apparatus may include at least one air-moving device. The number of the specific air exhausting devices can be set according to actual requirements, and is not limited here.

After the frequency converter is started, the first temperature detection module in each heat dissipation area of the frequency converter can detect the temperature of the corresponding area in the frequency converter cabinet in real time, aiming at the temperature of each heat dissipation area, when the temperature is lower than a first threshold value, the air cooling device and the water cooling device are not started, when the temperature is overhigh, taking the left side in the figure 5 as an example, when the temperature exceeds the first threshold value, the water pump is started, the water pump pumps water out of the water tank, the corresponding left control valve is started, at the moment, the water pumped out of the water pump flows back to the water tank from bottom to top through the left circulation channel, the second temperature detection module in the water tank synchronously detects the water temperature in the water tank, when the water temperature exceeds a second threshold value, or the temperature of the heat dissipation area detected by the first temperature detection module exceeds a third threshold value, the temperature in the frequency converter is over high, the water cooling device does not sufficiently meet the heat dissipation requirement, at the moment, the fan is started, the wind pendulum swings to send the wind generated by the fan to the heat dissipation area, so that the heat dissipation efficiency of the frequency converter is improved.
