[0002] Medical tissues require cooling during pretreatment to prevent them from becoming ineffective.

[0003] The current pretreatment equipment is a refrigerator, but refrigerators cannot meet the needs of batch operations. In order to meet the needs of batch operations, a racetrack was designed, and a cooling chamber was formed on the racetrack. Medical tissues move on the racetrack for continuous cooling. However, how to match the racetrack and meet the cooling requirements of pretreatment is a problem to be solved. Summary of the Invention

[0005] To address the above problems, the present invention provides a cooling air device, the cooling air device comprising:

[0006] A compressor capable of compressing refrigerant;

[0007] A condenser that receives refrigerant from the compressor and cools the refrigerant;

[0008] A capillary tube or expansion valve receives refrigerant from the condenser and throttles and reduces the pressure of the refrigerant;

[0009] An evaporator, wherein a first end of the evaporator receives refrigerant from the capillary tube or the expansion valve, and a second end of the evaporator transfers the refrigerant to the compressor;

[0010] A housing that houses the evaporator, and a first opening and a second opening are formed on opposite sides of the housing, respectively;

[0011] A first fan is located near the first opening to blow gas out of the housing.

[0012] A first flow guide, the first end of which is connected to the first fan, and the second end of which is used to connect to a cooling chamber through a first pipe, the cooling chamber being capable of accommodating the object to be cooled;

[0013] The second flow guide has a first end for connecting to the cooling chamber via a second pipe, and a second end for connecting to the second opening.

[0014] Furthermore, the cooling air device also includes:

[0015] A cold air temperature sensor is disposed inside the housing to detect the current cold air temperature;

[0016] A controller, connected to the expansion valve or the capillary tube and the cold air temperature sensor, adjusts the capillary tube or the expansion valve according to the difference between the current cold air temperature and the predetermined cold air temperature.

[0017] Further, the capillary includes:

[0018] A first capillary tube, the two ends of which are respectively connected to the condenser and the evaporator;

[0019] A second capillary tube, the first end of which is connected to the condenser via a solenoid valve, and the second end of which is connected to the evaporator.

[0020] The controller opens the solenoid valve when the current cold air temperature is higher than a first predetermined temperature, and closes the solenoid valve when the current cold air temperature is lower than a second predetermined temperature.

[0021] Furthermore, the evaporator is a finned evaporator, comprising fins and a coil. The evaporator is connected to the capillary tube and the compressor via the coil, or connected to the expansion valve and the compressor via the coil.

[0022] The air cooling device also includes:

[0023] An electric heating rod is inserted into the fins.

[0024] Furthermore, the cooling air device also includes:

[0025] A semiconductor refrigeration chip, wherein the heating surface of the semiconductor refrigeration chip is in close contact with the fins;

[0026] A coil temperature sensor, connected to the coil, is used to detect the current coil temperature.

[0027] The controller is also connected to the electric heating rod, the semiconductor cooling chip, and the coil temperature sensor. When the cold air temperature sensor detects that the current cold air temperature is lower than a predetermined low temperature, it controls the semiconductor cooling chip to work. When the current coil temperature detected by the coil temperature sensor is lower than a predetermined coil temperature, and the temperature difference between the current coil temperature and the current cold air temperature detected by the cold air temperature sensor is greater than a predetermined value, it shuts down the first fan and controls the electric heating rod to heat.

[0028] Furthermore, the cooling air device also includes:

[0029] A water receiving tray is disposed inside the housing and located below the evaporator;

[0030] A drain pipe is connected to the water receiving tray to drain water from the water receiving tray to the outside of the housing.

[0031] Furthermore, the cooling air device also includes:

[0032] The filter element is disposed at one end of the second flow guide near the housing.

[0033] Furthermore, the cooling air device also includes:

[0036] Furthermore, the cooling air device also includes:

[0037] A gas-liquid separator, wherein the second channel of the gas-liquid regenerator is connected to the compressor via the gas-liquid separator;

[0038] An oil separator is provided, through which the compressor is connected to the condenser.

[0039] Due to the above technical solution, the present invention has the following beneficial effects:

[0040] According to the cooling equipment of the present invention, the compressor turns the refrigerant into a high-temperature, high-pressure gaseous refrigerant. The condenser cools the high-temperature, high-pressure gaseous refrigerant to make it into a liquid refrigerant. The capillary tube or expansion valve turns the liquid refrigerant into a mist refrigerant. The mist refrigerant vaporizes in the evaporator, thereby lowering the evaporator temperature. The evaporator transfers the refrigerant to the compressor, facilitating the circulation of the refrigerant and achieving a continuous and stable low temperature in the evaporator. The low temperature of the evaporator in the casing is supplied in the form of cold air to the object to be cooled in the cooling chamber on the runway through the first fan, via the first guide vane and the first pipe, thereby achieving the cooling of the object to be cooled. The cold air in the cooling chamber is transferred to the evaporator in the casing through the second pipe and the second guide vane, achieving efficient cooling and regenerating the cold air. This reduces the energy consumption of the cooling equipment, and blowing the cold air directly onto the evaporator reduces frost formation on the evaporator. Attached Figure Description

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0050] The following describes the cooling air device according to an embodiment of the present invention.

[0051] like Figures 1 to 4 As shown, the air cooling device of this embodiment includes a compressor 100, a condenser 300, a capillary tube or expansion valve, an evaporator 610, a housing 800, a first fan 710, a first air guide 720, and a second air guide 730.

[0052] First, the compressor 100 and condenser 300 will be described. The compressor 100 compresses the refrigerant. The condenser 300 receives the refrigerant from the compressor 100 and cools it. The refrigerant can be Freon, etc. The cooling system may also include a second fan that blows air onto the condenser 300 to lower its temperature.

[0053] The compressor 100 can turn the refrigerant into a high-temperature, high-pressure gaseous refrigerant, and the condenser 300 cools the high-temperature, high-pressure gaseous refrigerant to turn it into a liquid refrigerant.

[0054] Next, the capillary tube and expansion valve will be explained. The capillary tube or expansion valve receives refrigerant from the condenser 300 and throttles and reduces the pressure of the refrigerant.

[0055] Both capillary tubes and expansion valves can throttle and compress the refrigerant, thereby turning the liquid refrigerant into a mist-like refrigerant.

[0056] Next, the evaporator 610 will be described. The first end of the evaporator 610 receives refrigerant from a capillary tube or expansion valve, and its second end transfers the refrigerant to the compressor 100.

[0057] The mist-like refrigerant vaporizes the evaporator 610, thereby lowering the temperature of the evaporator 610. The evaporator 610 then transfers the refrigerant to the compressor 100, facilitating the circulation of the refrigerant and thus achieving a continuous and stable low temperature in the evaporator 610.

[0058] Finally, the housing 800, the first fan 710, the first diffuser 720, and the second diffuser 730 are described. The housing 800 houses the evaporator 610, and a first opening and a second opening are formed on opposite sides of the housing 800, respectively. The first fan 710 is located near the first opening to blow gas out of the housing 800. The first end of the first diffuser 720 is connected to the first fan 710, and its second end is used to connect to a cooling chamber through a first pipe, the cooling chamber being capable of accommodating an object to be cooled. The first end of the second diffuser 730 is used to connect to the cooling chamber through a second pipe, and its second end is connected to a second opening. The object to be cooled may be medical tissue, etc.

[0059] Cooling chambers are installed on the runway, and objects to be cooled pass through the cooling chambers, thereby cooling the objects.

[0060] The shell 800 can seal the evaporator 610, reduce the heat exchange between the evaporator 610 and the outside, and concentrate the low temperature of the evaporator 610 inside the shell 800.

[0061] The first fan 710 generates strong convection, rapidly transferring the low temperature of the evaporator 610 to the first air guide 720 in the form of cold air. The first air guide 720 then rapidly transfers the cold air to the cooling chamber through the first duct, thereby cooling the objects to be cooled within the cooling chamber. The first duct connects the first air guide 720 to the cooling chamber, allowing the main body of the cooling equipment and the cooling chamber to be relatively independent of each other, facilitating flexible arrangement.

[0062] The second air guide 730 redirects the cooled air from the cooling chamber, after cooling the object to be cooled, back into the housing 800 through the second pipe and the second opening, thus recirculating and regenerating the cold air and significantly reducing the energy consumption of the cooling equipment. Furthermore, directing the cold air directly onto the evaporator 610 reduces frost buildup on the evaporator 610.

[0063] In the above-mentioned air-cooling equipment, the compressor 100 turns the refrigerant into a high-temperature, high-pressure gaseous refrigerant. The condenser 300 cools the high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant. The capillary tube or expansion valve turns the liquid refrigerant into a mist refrigerant. The mist refrigerant vaporizes in the evaporator 610, thereby lowering the temperature of the evaporator 610. The evaporator 610 transfers the refrigerant to the compressor 100, facilitating the circulation of the refrigerant and thus achieving a continuous and stable low temperature in the evaporator 610. The first fan 710 delivers the low temperature of the evaporator 610 inside the casing 800 as cold air through the first guide 720 and the first pipe to the object to be cooled in the cooling chamber on the runway, thereby achieving cooling of the object to be cooled. The cold air in the cooling chamber is transferred to the evaporator 610 inside the casing 800 through the second pipe and the second guide 730, achieving efficient cooling and regenerating the cold air. This can reduce the energy consumption of the cooling equipment, and blowing the cold air directly onto the evaporator 610 can reduce the frosting of the evaporator 610.

[0064] In some embodiments of the present invention, the cooling device further includes a cooling temperature sensor and a controller. The cooling temperature sensor is disposed within the housing 800 to detect the current cooling temperature. The controller is connected to an expansion valve or capillary tube and the cooling temperature sensor to adjust the capillary tube or expansion valve according to the difference between the current cooling temperature and a predetermined cooling temperature.

[0065] A cold air temperature sensor installed inside the housing 800 can obtain the current cold air temperature inside the housing 800 in a timely and accurate manner. By controlling the opening of the expansion valve or capillary tube through the controller, the temperature of the evaporator 610 can be adjusted so that the current cold air temperature is the predetermined cold air temperature.

[0066] Furthermore, the capillary includes a first capillary 510, a second capillary 520, and a solenoid valve 530. The two ends of the first capillary 510 are connected to the condenser 300 and the evaporator 610, respectively. The first end of the second capillary 520 is connected to the condenser 300 via the solenoid valve 530, and its second end is connected to the evaporator 610. The controller opens the solenoid valve 530 when the current cold air temperature is higher than a first predetermined temperature, and closes the solenoid valve 530 when the current cold air temperature is lower than a second predetermined temperature.

[0067] like Figure 3 and Figure 4 As shown, temperature control is achieved through the first capillary tube 510, the second capillary tube 520, and the solenoid valve 530. Since medical tissues require very low temperatures, the normally open first capillary tube 510 can stably maintain the low temperature of the evaporator 610, and the solenoid valve 530 controls the flow rate of refrigerant through the second capillary tube 520, thereby achieving precise temperature control of the evaporator 610.

[0068] Capillary tubes do not require electrical control, have excellent stability, and can achieve a large flow rate of refrigerant, avoiding the very serious consequences of medical tissue failure caused by possible expansion valve failure or abnormal preset temperature settings. Moreover, capillary tubes are less expensive than expansion valves.

[0069] By controlling the flow rate of refrigerant through the second capillary tube 520 using the solenoid valve 530, precise temperature regulation can be achieved to meet the needs of medical tissue cooling.

[0070] For example, the temperature required for medical tissue is -10 degrees Celsius. When the cold air temperature is higher than -10 degrees Celsius, the solenoid valve 530 is opened; when the cold air temperature is lower than -14 degrees Celsius, the solenoid valve 530 is closed.

[0071] In some embodiments of the present invention, the evaporator 610 is a finned evaporator 612 type evaporator 610, which includes fins 612 and coils 611. The evaporator 610 is connected to the capillary tube and the compressor 100 through the coils 611, or connected to the expansion valve and the compressor 100 through the coils 611. The cooling equipment also includes an electric heating rod 613, which is inserted into the fins 612. The finned evaporator 610 is known technology and will not be described in detail here.

[0072] like Figure 2 As shown, an electric heating rod 613 is inserted into the fin 612. Due to the very low cooling temperature, frost easily forms on the surface of the evaporator 610. If frost forms, the cooling effect will be reduced, the wind resistance will increase, and the air volume will be reduced.

[0073] Heating the fins 612 with the electric heating rod 613 can dissolve the frost layer on the surface of the evaporator 610.

[0074] Furthermore, the cooling device also includes a thermoelectric cooler and a coil temperature sensor. The heating surface of the thermoelectric cooler is in close contact with the fins 612. The coil temperature sensor is connected to the coil 611 to detect the current coil temperature of the coil 611. The controller is also connected to the electric heating rod, the thermoelectric cooler, and the coil temperature sensor. When the cooling air temperature sensor detects that the current cooling air temperature is lower than a predetermined low temperature, it controls the thermoelectric cooler to operate. When the current coil temperature detected by the coil temperature sensor is lower than a predetermined coil temperature, and the temperature difference between the current coil temperature and the current cooling air temperature detected by the cooling air temperature sensor is greater than a predetermined value, the first fan 710 is turned off, and the electric heating rod 613 is controlled to heat the coil.

[0075] The heating surface of the thermoelectric cooler is attached with fins 612, which can heat the fins 612 and reduce frost formation on them. Although the heating surface of the thermoelectric cooler increases the temperature of the evaporator 610 and the temperature of the cold air, the cooling surface of the thermoelectric cooler is suspended, allowing the cold air to blow over it and lower its temperature. Therefore, the thermoelectric cooler has a relatively small impact on the temperature of the cold air. Thus, using a thermoelectric cooler can reduce frost formation on the evaporator 610 with a relatively small impact on the temperature of the cold air, allowing the first fan 710 to operate continuously during this process.

[0076] When the cold air temperature sensor detects that the current cold air temperature is lower than the predetermined low temperature, it indicates that the temperature of the evaporator 610 is already very low, and there is a high probability that the evaporator 610 will frost over. The controller then activates the thermoelectric cooler to heat the fins 612, thereby reducing frost formation on the evaporator 610. Moreover, during the process of the thermoelectric cooler heating the evaporator, the current cold air temperature will rise slightly, but the increase will be limited from the predetermined low temperature (below the lowest value of the predetermined temperature range required by the object to be cooled), thus maintaining the object to be cooled within the predetermined temperature range.

[0077] The current coil temperature can be obtained in a timely and accurate manner through the coil temperature sensor. When the evaporator 610 is frosted (fins 612 and coil 611 are frosted), the temperature of coil 611 will be very low. However, due to the reduced air resistance and air volume of the cold air, the cooling efficiency will decrease. The current cold air temperature is not high. In order to maintain the predetermined cold air temperature, the temperature of the evaporator 610 will continue to decrease, thus creating a vicious cycle.

[0078] When the current coil temperature detected by the coil temperature sensor is lower than the predetermined coil temperature, and the temperature difference between the current coil temperature and the current cold air temperature detected by the cold air temperature sensor is greater than the predetermined value, it indicates that the frosting phenomenon on the evaporator 610 is already severe, and the low temperature of the evaporator cannot generate sufficiently low-temperature cold air. At this time, the controller shuts off the first fan 710 and controls the electric heating rod 613 to operate, which can quickly raise the temperature of the evaporator 610. The shutdown of the first fan 710 can maintain the high temperature of the evaporator 610 and prevent the high temperature of the evaporator 610 from being transferred to the object to be cooled.

[0079] In some embodiments of the present invention, the cooling air device further includes a water collection tray 620 and a drain pipe. The water collection tray 620 is disposed inside the housing 800 and below the evaporator 610. The drain pipe is connected to the water collection tray 620 to drain water from the water collection tray 620 to the outside of the housing 800.

[0080] During the defrosting process of evaporator 610, water will drip from evaporator 610. This water will be discharged from housing 800 in a timely manner through water tray 620 and drain pipe to prevent the water from freezing again and increasing the wind resistance of cold air.

[0081] Furthermore, the air cooling device also includes a filter element, which is disposed at one end of the second air guide 730 near the housing 800.

[0082] The filter element can filter impurities and water vapor brought from the cooling chamber, preventing contamination of the evaporator 610 and reducing frost formation on the evaporator 610, thereby improving the cooling efficiency of the evaporator 610.

[0083] In some embodiments of the present invention, the air cooling device further includes a dryer filter 400, and the condenser 300 is connected to a capillary tube or an expansion valve through the dryer filter 400.

[0084] The refrigerant can be filtered through the dryer filter 400 to prevent clogging of the capillary tube or expansion valve.

[0085] Furthermore, the air cooling equipment also includes a gas-liquid regenerator, which includes a first channel and a second channel that are independent of each other and adjacent to each other. The first channel and the second channel are capable of heat exchange. The two ends of the first channel are respectively connected to the evaporator 610 and the compressor 100. The evaporator 610 is connected to the compressor 100 through the first channel. The two ends of the second channel are respectively connected to the condenser 300 and the dryer filter 400. The condenser 300 is connected to the dryer filter 400 through the second channel.

[0086] like Figure 4 As shown, the liquid refrigerant in the condenser 300 flows to the dryer filter 400 through the gas-liquid regenerator, and the refrigerant in the evaporator 610 flows to the compressor 100 through the gas-liquid regenerator.

[0087] Because medical tissues require very low temperatures, the refrigerant in the evaporator 610 is very cold and flows directly to the compressor 100. The compressor 100 is relatively inefficient at compressing the cold refrigerant to form a high-temperature, high-pressure gaseous refrigerant, and liquid refrigerant is prone to flowing into the compressor 100, causing liquid slugging.

[0088] The liquid refrigerant passing through the condenser 300 absorbs heat from the low-temperature gaseous refrigerant passing through the evaporator 610 in the gas-liquid refrigerant recirculation unit. This lowers the temperature of the refrigerant flowing into the dryer filter 400 and raises the temperature of the refrigerant flowing into the compressor 100. The lower-temperature refrigerant flows into the expansion valve or capillary tube and then into the evaporator 610, increasing the refrigeration efficiency. The higher-temperature refrigerant flows into the compressor 100, increasing the compressor's compression efficiency. The increased temperature of the refrigerant also causes it to vaporize, preventing liquid refrigerant from flowing into the compressor 100 and causing liquid slugging.

[0089] Furthermore, the air cooling equipment also includes a gas-liquid separator 220 and an oil separator 210. The second channel of the gas-liquid regenerator is connected to the compressor 100 through the gas-liquid separator 220. The compressor 100 is connected to the condenser 300 through the oil separator 210.

[0090] The refrigerant flowing through the gas-liquid regenerator flows into the gas-liquid separator 220, which further separates the liquid refrigerant to prevent it from flowing into the compressor 100.

[0091] The gaseous refrigerant flowing through the compressor 100 passes through the oil separator 210, which filters out the oil in the refrigerant.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
