Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 to 6, according to a first aspect of the present invention, there is provided a cold-heat cycle apparatus comprising a regenerator assembly 1 for treating a treated working medium, which recovers heat or cold of the treated working medium.
For example, after cryotherapy is performed, a low-temperature working medium (e.g., liquid nitrogen or nitrogen gas) after the therapy is output from the reflux end of the therapy apparatus to the heat regenerator assembly 1, and meanwhile, a high-temperature working medium (e.g., absolute ethyl alcohol) is transmitted from the second working medium supply unit 5 (high-temperature working medium supply unit) to the heat regenerator assembly 1, so that the high-temperature working medium and the low-temperature working medium after the therapy exchange heat, and the low-temperature working medium after the therapy tends to normal temperature for subsequent operation. Correspondingly, after the rewarming operation is performed, the treated high-temperature working medium is output to the heat regenerator assembly 1 from the backflow end of the treatment instrument, and meanwhile, the low-temperature working medium is transmitted to the heat regenerator assembly 1 from the first working medium supply unit 3 (low-temperature working medium supply unit), so that the heat exchange is performed between the low-temperature working medium and the treated high-temperature working medium, and the treated high-temperature working medium tends to normal temperature so as to facilitate the subsequent operation. Therefore, the invention achieves the purpose of keeping the cold-heat balance and the cold-heat balance of the system by utilizing the mutual consumption of the cold and heat of the system.
In a preferred embodiment, the heat exchange between the high temperature working medium and the treated low temperature working medium is performed in the heat exchange tube 4 of the regenerator assembly 1. The process of heat exchange between the low-temperature working medium and the treated high-temperature working medium is carried out in the heat exchange tube 4 and the cold guide plate component 2 of the heat regenerator assembly 1.
Specifically, the regenerator assembly 1 includes a cold guide plate assembly 2 and a heat exchange tube 4, the heat exchange tube 4 is disposed on the regenerator body 11, and the cold guide plate assembly 2 is disposed on a cabinet assembly 7 described below. The cold guide plate assembly 2 is selectively communicated with the first working medium supply unit 3. The heat exchange tube 4 includes a first channel 411 and a second channel 421. The first passage 411 is in selective communication with the second working substance supply unit 5. The second channel 421 is arranged in the first channel 411, and the second channel 421 is communicated with a return pipe of the therapeutic apparatus to receive the working medium after treatment.
When the first channel 411 is communicated with the second working medium supply unit 5, the cold guide plate assembly 2 is not communicated with the first working medium supply unit 3, and the working medium in the first channel 411 and the working medium in the second channel 421 exchange heat. In other words, the first channel 411 is communicated with the second working medium supply unit 5, the high-temperature working medium is conveyed into the first channel 411, the second channel 421 inside the first channel receives the treated low-temperature working medium, therefore, the treated low-temperature working medium exchanges heat with the high-temperature working medium in the first channel 411 in the second channel 421, the temperature of the treated low-temperature working medium can be raised to be close to the normal temperature, and the operation safety can be improved.
When the cold guide plate assembly 2 is communicated with the first working medium supply unit 3, the first channel 411 is not communicated with the second working medium supply unit 5, and the working medium in the cold guide plate assembly 2 exchanges heat with the working medium in the second channel 421. That is to say, the cold guide plate assembly 2 is communicated with the first working medium supply unit 3, so that the low-temperature working medium is conveyed into the cold guide plate assembly 2, and the second channel 421 receives the treated high-temperature working medium, so that the treated high-temperature working medium and the low-temperature working medium in the cold guide plate assembly 2 perform heat exchange, and the temperature of the treated high-temperature working medium can be reduced to be close to normal temperature, thereby improving the operation safety.
In a specific embodiment, the heat exchange tube 4 is configured as an inner tube 42 for forming the second channel 421 and an outer tube 41 fitted over the inner tube 42, with the first channel 411 formed between the inner tube 42 and the outer tube 41. In order to improve the efficiency of heat exchange, the outer tube 41 is provided with fins 414 on the outside.
Further, the number of the heat exchange tubes 4 is plural, and the plural heat exchange tubes 4 are connected in series or in parallel by the connection tube 43. As shown in fig. 1, the heat exchange tubes 4 may be stacked in the height direction (Z-axis direction) of the regenerator body 11, or may be arranged side by side in the width direction (Y-axis direction) of the regenerator body 11.
Further, the outer tube 41 may be provided with individual fins 414, or a plurality of outer tubes 41 may share some of the fins 414. The fins 414 are intended to increase the heat exchange area, and thus the present invention is not limited to the specific arrangement of the fins 414.
The sides of the outer tube 41 of the heat exchange tubes 4 are provided with a first inlet 412 and a first outlet 413 communicating with the first channel 411, respectively, and the first inlet 412 and the first outlet 413 on the outer tube 41 serve to communicate the first channels 411 of the plurality of heat exchange tubes 4. For example, the first outlet 413 of one of the outer tubes 41 is connected to the first inlet 412 of the other outer tube 41 adjacent to the outer tube 41; specifically, they are connected by a connection pipe 43 so that the high temperature working medium can flow into the first passage 411 formed in each outer pipe 41.
As shown in fig. 2-5, the first inlet 412 and the first outlet 413 of the outer tube 41 are disposed on the sidewalls thereof, respectively. It will be understood that the first inlet 412 of one of the outer tubes 41 (e.g. the first outer tube 41a) is connected to the high temperature medium inlet port 12, and the high temperature medium inlet port 12 is connected to the output of the second medium supply unit 5, so that the high temperature medium can flow into each of the first passages 411 through the high temperature medium inlet port 12.
Furthermore, a first outlet 413 of an outer tube 41 (for example the last outer tube 41b) is connected to the working medium outlet 13, and the working medium outlet 13 is connected to the return end of the second working medium supply unit 5, so that each first channel 411 is connected to the return end of the second working medium supply unit 5 via the working medium outlet 13. Therefore, the high temperature working medium in the first channel 411 can return to the second working medium supply unit 5 under the pressure of the second working medium supply unit 5 after heat exchange.
Preferably, a buffer tank is arranged between the working medium outlet 13 and the second working medium supply unit 5, and the high-temperature working medium discharged through the working medium outlet 13 is temporarily stored through the buffer tank. When the system stops working and under the condition that the second working medium supply unit 5 has no pressure, the high-temperature working medium recovered from the buffer tank is input into the second working medium supply unit 5 so as to ensure the safety.
Further, the outer portion of the outer tube 41 of the heat exchange tube 4 may be further provided with a thermal insulation layer to maintain the temperature of the heat exchange tube 4 and prevent frost from forming on the heat exchange tube 4.
When the low-temperature working medium after the heat exchange is carried out, the temperature of the low-temperature working medium is raised to the normal temperature, namely, the low-temperature working medium is changed from liquid state (liquid nitrogen) to gas state (nitrogen), so that the second channel 421 can be connected with the environment, and the low-temperature working medium after the heat exchange can be discharged to the environment.
As shown in fig. 2-5, the upper and lower ends of the inner tube 42 are respectively the working medium inlet and outlet. The plurality of inner tubes 42 are connected in series to communicate the second passages 421. The working medium inlet of one of the inner tubes 42 is communicated with the return tube of the therapeutic apparatus, so that the second channel 421 can receive the low-temperature working medium (or high-temperature working medium) after treatment.
As shown in fig. 6, the cold conducting plate assembly 2 includes a cold conducting plate 21 and a cold conducting tube 22 disposed on the cold conducting plate 21. The heat regenerator assembly 1 further comprises a fan 6, and when the cold guide pipe 22 is communicated with the first working medium supply unit 3, the fan 6 is started to promote the heat exchange between the working medium in the cold guide pipe 22 and the working medium in the second channel 421.
Specifically, when the cold guide plate assembly 2 is communicated with the first working medium supply unit 3, the low-temperature working medium is conveyed into the cold guide pipe 22, the second channel 421 receives the treated high-temperature working medium, and the fan 6 is started, so that the cold energy in the cold guide pipe 22 is transmitted into the heat exchange pipe 4, and the temperature of the treated high-temperature working medium in the second channel 421 can be reduced to tend to normal temperature.
As shown in fig. 2, the fans are arranged side by side along the length direction of the cooling duct 22 at 6, and the length direction of the cooling duct 22 coincides with the length direction of the heat exchange tube 4 (X-axis direction as shown in fig. 1), so that the medium in the heat exchange tube 4 is uniformly cooled.
Further, as shown in fig. 6, the cold guiding pipe 22 is a serpentine pipe, and the second inlet 221 of the cold guiding pipe 22 and the second outlet 222 of the cold guiding pipe are located on the same side of the cold guiding plate 21 (as shown in fig. 1), so that the path of the low-temperature working medium in the cold guiding pipe 22 is extended as much as possible, so as to maximize the use of the cold energy of the low-temperature working medium.
The second inlet 221 of the cold conducting pipe 22 is connected to the first working medium supply unit 3, and the second outlet 222 of the cold conducting pipe 22 is connected to the first working medium replenishing unit or environment. Therefore, the low-temperature working medium after heat exchange returns to the first working medium supplementing unit from the second outlet 222 of the cold guide pipe 22, and the first working medium supplementing unit can supplement the first working medium (low-temperature working medium) to the first working medium supply unit 3, so that cyclic utilization can be realized.
Or the low-temperature working medium after heat exchange can be discharged to a discharge pipeline through the second outlet 222 of the cold conducting pipe 22 for subsequent treatment.
The second channel 421 may be connected to a reservoir for heat exchange of the treated high temperature working medium. The high-temperature working medium after heat exchange is changed from a gas state to a liquid state, so that the high-temperature working medium can be collected through the liquid storage device.
It should be noted that, when heat exchange is performed with the low-temperature working medium after treatment, the second working medium (high-temperature working medium) in the first channel 411 is only used for heat exchange but not for treatment, so that the second working medium in the first channel 411 is only circulated in the system, and after heat exchange, the second working medium can enter the buffer tank for temporary storage and then can be input into the second working medium supply unit 5 for cyclic utilization. When the treated high-temperature working medium is subjected to heat exchange, the treatment apparatus is in contact with a target area of a human body, so that the second working medium (the high-temperature working medium) entering the second channel 421 through the return pipe of the treatment apparatus enters the liquid storage device to be collected and is not recycled.
According to a second aspect of the present invention, as shown in fig. 7-11, the present invention provides a high-low temperature complex therapy system, which comprises the above-mentioned cooling and heating cycle device.
Specifically, the high-low temperature compound treatment system of the present invention includes a frame 10, wherein the regenerator assembly 1, the first working medium supply unit 3 and the second working medium supply unit 5 are all disposed in the frame 10. In addition, the high-low temperature compound treatment system of the invention also comprises a case assembly 7 arranged in the frame 10, and a controller is arranged in the case assembly 7.
As shown in fig. 1, 7 and 9, cold guide plate assembly 2 and regenerator body 11 are located on the same side of cabinet assembly 7. Specifically, lead cold plate subassembly 2 and set up on quick-witted case assembly 7's lateral wall to lead cold plate subassembly 2 both can cool off the high temperature working medium in second passageway 421, can also cool off quick-witted case assembly 7, can not work under too high ambient temperature with controller and other components and parts in the assurance cooling machine case assembly 7.
The first working medium supply unit 3 is selectively communicated with the cold guide plate assembly 2 through a valve body assembly 8, and the second working medium supply unit 5 is selectively communicated with the first passage 411 through the valve body assembly 8.
Specifically, as shown in fig. 10 and 11, the valve assembly 8 includes a regenerator second working medium output valve 81, a second working medium backflow control solenoid valve 82, a first working medium backflow polymerization three-way valve 83, a cabinet output control valve 84, a backflow perfusion system solenoid valve 85, and a regenerator cold-conducting output valve 86.
As shown in fig. 10, the cold guide output port 31 of the first working medium supply unit 3 is connected to the cabinet output control valve 84 through a pipeline, the cabinet output control valve 84 is connected to the cold guide plate input port 87, and the cold guide plate input port 87 is connected to the second inlet 221 of the cold guide plate assembly 2, so that the cabinet output control valve 84 can control the on-off of the pipeline between the first working medium supply unit 3 and the cold guide pipe 22 of the cold guide plate assembly 2.
The second working medium backflow control solenoid valve 82 is respectively connected with the working medium gathering port 13 and the buffer tank, and the second working medium backflow control solenoid valve 82 can control the second working medium which is subjected to heat exchange in the first channel 411 to flow into the buffer tank from the working medium gathering port 13.
The perfusion return system solenoid valve 85 is connected to the return pipe of the therapeutic apparatus, and is used for controlling the treated medium in the return pipe of the therapeutic apparatus to flow to the second channel 421.
The valves are connected to a controller in the cabinet assembly 7, so that the controller can control the on/off of each passage/pipeline by opening and closing the valves.
Further, the bottom of the chassis assembly 1 is provided with a traveling wheel 9 so as to facilitate the high-low temperature compound treatment system. Wherein, the walking wheel 9 can be one or more of a universal wheel, a directional wheel, a power-assisted wheel and an electric control wheel.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict.
