It is one of the important pieces of equipment in the upstream support link of the semiconductor industry.

[0003] The inventors discovered that existing refrigeration systems can only control temperature within a single temperature range, which cannot meet the requirement of simultaneous control of different temperature zones in semiconductor processing equipment. Summary of the Invention

[0013] In an optional embodiment, the first end outlet of the vortex tube is provided with a regulating valve.

[0014] In a second aspect, the present invention provides a semiconductor temperature control cooling method, applied to a semiconductor temperature control cooling system as described in any of the foregoing embodiments, comprising a high-temperature zone cooling process S1 and a low-temperature zone cooling process S2.

[0015] S1, Cooling process in the high-temperature zone:

[0029] In an optional implementation, when the semiconductor temperature control cooling system cools the same device, it first undergoes a high-temperature cooling process in step S1, and then a low-temperature cooling process in step S2.

[0030] The beneficial effects of the embodiments of the present invention include, for example:

[0031] The semiconductor temperature-controlled refrigeration system of this invention uses a vortex tube to divide the gas outlet of the compressor into cold and hot streams, achieving refrigeration in both low and high temperature ranges.

When used on the same device, the refrigerant first undergoes preliminary cooling through the first evaporator, and then undergoes further cooling through the second evaporator. The advantage of secondary cooling is that it reduces the impact of temperature fluctuations caused by the device on the refrigeration system, reduces the temperature change range required for each cooling process, and improves temperature control accuracy.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0043] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0045] Please refer to Figure 1 The semiconductor temperature-controlled refrigeration system 100 of this embodiment includes a compressor 10, a vortex tube 20, a first condenser 30, an ejector 40, a first evaporator 50, a first gas-liquid separator 60, a second condenser 31, a valve body 70, a second evaporator 51, and a second gas-liquid separator 61, wherein:

[0046] The outlet of compressor 10 is connected to the inlet of vortex tube 20. The first end outlet 21 of vortex tube 20 is connected to the inlet of first condenser 30. The outlet of first condenser 30 is connected to the pressure end inlet 41 of ejector 40. The outlet of ejector 40 is connected to the inlet of first evaporator 50. The outlet of first evaporator 50 is connected to the inlet of first gas-liquid separator 60. The gas outlet of first gas-liquid separator 60 is connected to the inlet of compressor 10. The liquid outlet of first gas-liquid separator 60 is connected to the ejector end inlet 42 of ejector 40.

[0047] It is understood that the ejector 40 includes an outlet, a pressure-end inlet 41, and an ejector-end inlet 42. The high-temperature, high-pressure gas output from the compressor 10 enters the vortex tube 20 and is separated into two fluids, a cold fluid and a hot fluid. The first gas enters the first condenser 30 and condenses to form condensate. The condensate enters the ejector 40 from the pressure-end inlet 41 as the working medium. The liquid output from the liquid outlet of the first gas-liquid separator 60 enters the ejector 40 from the ejector end as the ejector medium, mixes with the working medium, and is ejected from the outlet of the ejector 40 into the first evaporator 50 for evaporation and heat absorption, thereby achieving cooling in the high-temperature zone. The gas outlet of the first gas-liquid separator 60 is connected to the inlet of the compressor 10, and the separated gas enters the compressor 10 for further compression, thus achieving cyclic cooling in the high-temperature zone.

[0048] The second outlet 22 of the vortex tube 20 is connected to the inlet of the second condenser 31. The outlet of the second condenser 31 is connected to the inlet of the second evaporator 51 via the valve body 70. The outlet of the second evaporator 51 is connected to the inlet of the second gas-liquid separator 61, and the gas outlet of the second gas-liquid separator 61 is connected to the inlet of the compressor 10. The liquid outlet of the second gas-liquid separator 61 is connected to the ejector end inlet 42 of the ejector 40.

[0049] It should be noted that in this embodiment, both the first condenser 30 and the second condenser 31 are spiral tubular structures. Vapor passes through the condenser tubes, and heat is dissipated into the air through the tube walls, forming condensate. Optionally, both the first condenser 30 and the second condenser 31 are equipped with heat dissipation fins.

[0050] Similar to the refrigeration cycle in the high-temperature zone, refrigeration in the low-temperature zone is achieved through a series of interconnected components: compressor 10, second outlet 22 of vortex tube 20, second condenser 31, valve body 70, second evaporator 51, and second gas-liquid separator 61. The gas exiting from second outlet 22 enters the second condenser 31 for condensation, then passes through valve body 70 for further cooling and pressure reduction before entering the second evaporator 51 for low-temperature refrigeration. It then enters the second gas-liquid separator 61 for gas-liquid separation, and the separated gas enters the compressor 10 for further compression. Similarly, the liquid separated by the second gas-liquid separator 61 enters the ejector inlet 42 of ejector 40 as the ejector medium.

[0051] Unlike the refrigeration cycle in the high-temperature zone, which uses an ejector 40, the refrigeration cycle in the low-temperature zone uses a valve body 70. The ejector 40 reduces throttling losses. In this embodiment, the valve body 70 is an electronic expansion valve.

[0052] Furthermore, in this embodiment, the semiconductor temperature-controlled refrigeration system 100 also includes a third gas-liquid separator 62. The third gas-liquid separator 62 is connected between the second end outlet 22 of the vortex tube 20 and the second condenser 31. The second end outlet 22 of the vortex tube 20 is connected to the inlet of the third gas-liquid separator 62. The gas outlet of the third gas-liquid separator 62 is connected to the inlet of the second condenser 31. The liquid outlet of the third gas-liquid separator 62 is connected to the ejector end inlet 42 of the ejector 40. Since the gas temperature at the second end outlet 22 is lower than the temperature of the gas at the first end, the gas at the second end outlet 22 is prone to contain liquid. The function of the third gas-liquid separator 62 is to separate the second end gas from a small amount of liquid at the second end outlet 22, thereby improving the efficiency of the subsequent second condenser 31 and second evaporator 51. The liquid separated by the third gas-liquid separator 62 enters the ejector end inlet 42 of the ejector 40 to serve as the ejector medium.

[0053] To facilitate gas-liquid separation, the gas outlet and liquid outlet of the first gas-liquid separator 60 are located at the top and bottom, respectively. Similarly, the gas outlet and liquid outlet of the second gas-liquid separator 61 are located at the top and bottom, respectively. The gas outlet and liquid outlet of the third gas-liquid separator 62 are located at the top and bottom, respectively. It is understood that since the density of gas is less than that of liquid, when the gas-liquid separators are operating, gas is output from the top and liquid is output from the bottom.

[0054] In this embodiment, a pressure detection element is provided at the inlet of the vortex tube 20 to detect the pressure at the inlet of the vortex tube 20. Furthermore, a regulating valve is provided at the first outlet 21 of the vortex tube 20. The pressure detection element detects the pressure, and the inlet pressure of the vortex tube 20 is adjusted by adjusting the power of the compressor 10. The cold flow ratio can be changed by adjusting the regulating valve at the first outlet 21, thereby changing the cold and hot flow temperatures and achieving precise temperature control.

[0055] Furthermore, the first evaporator 50 and the second evaporator 51 can be used independently or in combination. Specifically, in this embodiment, the first evaporator 50 further includes a first pipe, with its two ends connected to the ejector 40 and the first gas-liquid separator 60, respectively. The second evaporator 51 further includes a second pipe, with its two ends connected to the valve body 70 and the second gas-liquid separator 61, respectively. The first evaporator 50 also includes a third pipe, and the second evaporator 51 further includes a fourth pipe, with the third and fourth pipes connected in series. It can be understood that the third and fourth pipes connect the first evaporator 50 and the second evaporator 51 in series in a single system to achieve secondary cooling of the same device. In other embodiments, the third and fourth pipes are respectively installed in different devices to meet the temperature requirements of different devices.

[0056] The semiconductor temperature-controlled refrigeration system 100 of the present invention can either use the first evaporator 50 and the second evaporator 51 to control the temperature of devices with different temperature requirements, or it can connect the first evaporator 50 and the second evaporator 51 in series in a single circulation system to achieve temperature control through secondary refrigeration of the same device. When used on the same device, the refrigerant first undergoes preliminary cooling through the first evaporator 50, and then undergoes further cooling through the second evaporator 51. The advantage of secondary cooling is that it reduces the impact of temperature fluctuations caused by the device on the refrigeration system and improves the temperature control accuracy.

[0057] Please combine Figures 2-4 This embodiment provides a semiconductor temperature-controlled cooling method applied to the aforementioned semiconductor temperature-controlled cooling system 100, which includes a high-temperature cooling process S1 and a low-temperature cooling process S2.

[0074] The beneficial effects of the semiconductor temperature-controlled cooling system 100 in this embodiment are:

[0075] The semiconductor temperature-controlled refrigeration system 100 of this invention uses a vortex tube 20 to divide the gas outlet of the compressor 10 into cold and hot streams, achieving refrigeration in both low and high temperature ranges. Simultaneously, an ejector 40 replaces the valve body 70 in the high-temperature zone, reducing throttling losses. The gas outlet of the gas-liquid separator is connected to the compressor 10 to form a complete loop, achieving cyclic refrigeration in both high and low temperature zones. At the same time, it prevents liquid from entering the compressor 10 and affecting its operating efficiency.
