Introduction
The relevance of the research topic is to design a cooler with natural cooling capacity for a 100 kW semiconductor power converter.
The level of knowledge on the subject. Many scientists, such as Johann Andreas von Segner, Heron of Alexandria, Victor Schauberger, Leopold Shergyue, Richard Clem, have studied the problem of converting the energy of fluid flow into energy, but this problem has not been studied thoroughly. Some problems should be considered and decided to be eliminated.
The goal of this paper is to design a naturally cooled cooler for a 100KW semiconductor power converter. The aim of this work is to improve the energy efficiency of the cooler by using the energy of the compressed flow as a result of its periodic braking.
In this work, the following research methods were used: comparison, generalization, modeling, description, experimentation, graphical analysis. The information base of the research was literary sources and patents, such as A. P. Levtsev, A. Makeev, Ya. A. Narvatov, A. Lysyakov, S. Kudashev, V. M. Ivanov, B. V. Semkin, A. A. Blinov, T. A. Volkova.
The novelty of this research is the design of a cooler with natural cooling capacity for 100KW semiconductor power converters, which will help to reduce power consumption losses and reduce explosion and fire hazards in industrial production facilities, introducing and using this laboratory equipment in practice for facilities requiring high heat, such as industrial sites; logistics centers; all possible use in underground structures where explosive gases may leakage of semiconductor devices, such as IGBTs, etc.
In this paper, the thermal properties are considered, and the experimental characteristics are analyzed. And the model is formalized in mathematical language. A new semiconductor power cooler is developed, and a description of the theoretical calculations is considered, and the theoretical heat dissipation is calculated and simulated for different parameters and the results of the design simulations are analyzed graphically.
Material and research methods
The study was carried out under natural and laboratory conditions in 2022. Laboratory experiments were carried out in the laboratory of the Institute of Mechanical and Power Engineering of the N.P. Ogarev Mordovia State Research University.
The authors analyzed the existing articles and patents on coolers [1-4]. Articles on the subject of research work [5-7] were studied. Amplitude-frequency and phase-frequency characteristics were plotted to determine the most efficient mode of operation, and mathematical energy conversion was performed on the constructed hydraulic circuit. The development of technological solutions for power semiconductor device coolers and the transfer of cooler hydrodynamics and its heat transfer energy were studied. To be clearer the thermal design of the liquid cooler, strength, hydrodynamic calculations and calculation of economic efficiency of the semiconductor devices after their introduction into the cooler. The methodology and scheme of the experiments were developed.

Based on the values obtained in Table 1, the AFC diagram was drawn.
As can be seen from the amplitude-frequency response plot (Figure 1), when the mass m is reduced to 50 kg and the softness l is reduced to 0.00008ms/N, the amplitude frequency decreases slightly compared to the reference value. When the mass m is increased to 100 kg and the compliance l is increased to 0.001 ms/N, the amplitude increases sharply by a factor of 10 or more. In this respect, this model is the best.
Figure 2 shows a schematic diagram of a laboratory setup with a pulsed circulating coolant.
The principle of operation of the scheme.
When the centrifugal pump 5 is turned on, it will supply the coolant through the natural cold cooler 6 to the heat exchanger 4. Then it returns back to the centrifugal pump 5 through one of the open valves of the shock valve 3. When the speed of the coolant is calculated, the valve of the shock valve 3 will quickly close. For exchange, the left valve. When the left valve is closed quickly, a hydraulic shock will occur, the revest pressure, wave of which will move the diaphragm 2. A portion of another coolant will be supplied to 7 and remove heat from the thyristor.
In a simplified from it includes 5 links: the first is hydraulic, take into account the friction losses of the input path with active resistance ri and the mass of water in the character mi; the second is a convertor, converts the pressure P2 into force, and the mass flow g into the diaphragm velocity v; the third is mechanical, takes into account the elastic properties of the diaphragm by the pliability T and the friction losses of the diaphragm about liquid active resistance r2;the fourth-the converter link, converts the force fi into pressure P3, and the linear velocity Vi into mass flow g2;the fifth link is hydraulic, take into accent the losses of the loss of the output path the diaphragm pump using the active resistance r3. As in Figure 3:

The calculation method of the micro-tank heat exchanger is studied, and the thermal efficiency is calculated to investigate the relationship between the flow rate and the input temperature, output temperature, heat loss, temperature difference and the related auxiliary quantities P, R. As in Figure 4: We can conclude that we have obtained a peak which is equal to Q = 4.5, which means that the design will work best under these conditions.
When considering the dependence of the third energy circuit, we can say that these indicators lead to an increase in efficiency with the growth of the parameters.
If we consider the phase-frequency characteristics, the dependence of all three energy circuits leads to a decrease of these parameters.
Moreover, in the course of this work we have a model on which we can understand which values have a greater influence on the desired value, i. e. the input temperature.
