Description

Technical Field

[0001] The utility model relates to diving equipment, in particular to an environmental temperature regulating device used in a decompression chamber. Background Art

[0002] When divers work underwater, they experience varying degrees of pressure changes due to water pressure. When divers return to the surface from deep sea, the gases in their bodies, mainly nitrogen and oxygen, expand due to the reduction in pressure. Without proper decompression procedures, gas expansion can lead to serious health problems such as decompression sickness, also known as decompression sickness or gas embolism.

[0003] In order to safely transition from a high-pressure environment to a normal atmospheric pressure environment, divers need to enter a special chamber, which is usually called a "decompression chamber" or "diving chamber". The decompression chamber is used to help divers safely transition from a high-pressure environment to normal atmospheric pressure after deep-water operations, and prevent the occurrence of decompression sickness by controlling the pressurization and decompression process. In addition, it can also be used in emergency situations, such as providing emergency rescue and treatment when divers encounter accidents.

[0004] During the pressurization process, as the pressure increases, the temperature of the gas in the cabin may rise. This is due to the physical phenomenon that the energy of the gas increases when it is compressed, causing the temperature to rise. During the decompression process, the pressure of the gas in the cabin decreases and the temperature will decrease because the energy of the gas decreases when it expands, causing the temperature to decrease.

[0005] However, most current temperature regulation systems for pressurized chambers rely on an endothermic-exothermic process and are usually operated using refrigerants. However, this system may have some limitations and potential problems. Since the decompression chamber is pressurized, if a refrigerant leak occurs, it may cause serious harm to the people in the chamber. In addition, electrical sparks in the chamber may also cause fires in the chamber.

[0006] Therefore, the industry has been paying continuous attention and working hard on how to design a product that can both ensure cabin safety and effectively regulate the temperature inside the cabin. Utility Model Content

Different from the prior art, a copper heat-conducting rod is sealed and passes through the wall of the decompression chamber, the end of the heat-conducting rod outside the chamber is fixedly connected to a refrigerant exchanger, the refrigerant outlet of the heat pump is connected to the inlet of the refrigerant exchanger, and the refrigerant inlet of the heat pump is connected to the outlet of the refrigerant exchanger.

[0009] Furthermore, the refrigerant exchanger includes two copper plates and one end cover, the two copper plates are arranged alternately and spirally curled, the inner ends of the two copper plates are connected, and the outer ends are inwardly buckled and closed, the end cover is sealed and welded to the top ends of the two copper plates to form a closed cavity one and cavity two, cavity one is filled with heat transfer oil, the inlet is opened on the end cover and communicated with the center of cavity two, and the outlet is opened on the copper plate and communicated with the outermost part of cavity two.

[0010] Furthermore, dense heat dissipation fins are cut out or fixed on the inner end portion and the circumferential circular surface of the heat conducting rod.

[0011] Furthermore, it also includes a magnetic coupling motor, the stator of the magnetic coupling motor is fixed on the outside of the bulkhead close to the heat conducting rod, the rotor of the magnetic coupling motor is fixed on the inside of the bulkhead close to the heat conducting rod, and the rotor is fixedly connected to the fan; the cover covers the fan and the heat conducting rod, an air inlet is opened on the cover corresponding to the fan, and an air outlet is opened on the cover at the far end of the air inlet.

[0012] Furthermore, a temperature control switch is arranged in the cavity 1, and the temperature control switch is connected to the power line of the magnetic coupling motor.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Safety isolation: The copper heat-conducting rod seals through the decompression chamber wall, achieving physical isolation between the inside and outside environments of the chamber, preventing the refrigerant from directly entering the decompression chamber, and also preventing the generation of electric sparks, greatly reducing safety risks.

[0015] Efficient heat exchange: Through the design of the heat conductive rod, the heat or cold generated by the heat pump outside the cabin can be efficiently transferred to the cabin, achieving fast and uniform temperature regulation.

[0016] Energy-efficient design: Heat pump systems are more energy-efficient than traditional air conditioning systems because they use energy more efficiently for heating and cooling.

[0018] Easy maintenance: The design of the heat transfer rod and refrigerant exchanger simplifies the system structure, reduces potential failure points, and makes maintenance and repair more convenient.

[0019] Improved reliability: The sealed heat-conducting rods that pass through the bulkhead reduce the possibility of direct contact between the cabin and the internal and external environments, thereby improving the reliability and stability of the entire system.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0028] See also Figure 1-5 , an environmental temperature regulating device for a decompression chamber, including a heat pump capable of heating and cooling, a copper heat-conducting rod 200 sealingly passing through a bulkhead 100 of the decompression chamber, an outer side end of the heat-conducting rod 200 fixedly connected to a refrigerant exchanger 300, a refrigerant outlet of the heat pump connected to an inlet 301 of the refrigerant exchanger 300, and a refrigerant inlet of the heat pump connected to an outlet 302 of the refrigerant exchanger 300.

[0029] In this embodiment, the refrigerant exchanger 300 includes two copper plates 303 and one end cover 304. The two copper plates 303 are arranged alternately and spirally curled. The inner ends of the two copper plates 303 are connected and the outer ends are closed inwardly. The end cover 304 is sealed and welded to the top ends of the two copper plates 303 to form a closed cavity 1 305 and a cavity 2 306. The cavity 1 305 is filled with heat transfer oil. The inlet 301 is opened on the end cover 304 and communicates with the center of the cavity 2 306. The outlet 302 is opened on the copper plate 303 and communicates with the outermost part of the cavity 2 306.

[0030] A heat pump is a device that can perform heating and cooling cycles. In cooling mode, the heat pump absorbs heat from the inside of the decompression chamber and transfers the heat to the external environment through the heat pump's circulation system. In heating mode, the heat pump absorbs heat from the external environment and releases the heat into the decompression chamber. The heat conducting rod 200 is made of copper, which is an excellent thermal conductor and can efficiently transfer heat. The heat conducting rod 200 passes through the bulkhead 100 of the decompression chamber and connects the refrigerant exchanger 300 inside and outside the chamber. The refrigerant exchanger 300 is composed of two copper plates 303 and an end cover 304 to form a closed cavity 305 and a cavity 306. The copper plates 303 are arranged alternately and spirally curled to increase the heat exchange area. The end cover 304 is sealed and welded to the top of the copper plate 303 to ensure the sealing of the refrigerant exchanger. The cavity 305 is filled with heat transfer oil, which has good thermal conductivity and heat storage capacity. When the refrigerant of the heat pump flows through the refrigerant exchanger 300, it exchanges heat with the heat transfer oil in the cavity 305, thereby adjusting the temperature of the heat transfer oil. The refrigerant of the heat pump flows out from the outlet of the heat pump and enters the inlet 301 of the refrigerant exchanger 300. Here, the refrigerant exchanges heat with the heat transfer oil and absorbs or releases heat. Then, the refrigerant flows through the second cavity 306, and finally flows out from the outlet 302, returns to the inlet of the heat pump, and completes the cycle. When refrigeration is required, the heat pump works in the refrigeration mode, and the refrigerant absorbs the heat of the heat transfer oil in the refrigerant exchanger 300, so that the temperature in the cabin decreases. When heating is required, the heat pump works in the heating mode, and the refrigerant releases heat in the refrigerant exchanger 300, so that the temperature in the cabin rises. The entire system is designed to be sealed, which prevents the refrigerant from directly entering the decompression chamber, thereby improving the safety of the environment in the cabin. The environmental temperature regulating device of this embodiment can achieve precise control of the temperature in the decompression chamber, while ensuring the safety and reliability of the system.

[0031] In another preferred embodiment, dense heat dissipation fins are cut or fixed on the cabin inner side end and the circumferential circular surface of the heat conducting rod 200. The heat dissipation fins can significantly increase the surface area of ​​the cabin inner side of the heat conducting rod 200, thereby improving the heat exchange efficiency with the cabin air. The design of the fins helps to transfer heat from the heat conducting rod to the cabin air more quickly.

[0032] In another preferred embodiment, a magnetic coupling motor is also included. The stator 400 of the magnetic coupling motor is fixed on the outside of the bulkhead 100 near the heat conducting rod 200, and the rotor 500 of the magnetic coupling motor is fixed on the inside of the bulkhead 100 near the heat conducting rod 200. The rotor 500 is fixedly connected to the fan 600. The cover 700 covers the fan 600 and the heat conducting rod 200. An air inlet 701 is provided on the cover 700 corresponding to the fan 600, and an air outlet 702 is provided on the cover 700 at the far end of the air inlet 701. The stator 400 is installed on the outside of the bulkhead 100 of the decompression chamber, and the rotor 500 is installed on the inside of the bulkhead 100. The two are coupled by magnetic field, and there is no need for physical connection through the bulkhead, which enhances the safety of the system. The rotor 500 is fixedly connected to the fan 600. When the magnetic coupling motor is working, the rotation of the rotor drives the fan 600 to operate, thereby realizing the flow of air. The cover 700 covers the fan 600 and the heat-conducting rod 200, which plays a role in protecting internal components and optimizing the air flow path. An air inlet 701 is provided on the cover 700 corresponding to the fan 600 to allow external air to enter; and an air outlet 702 is provided at the far end of the cover 700 so that the air heated or cooled by the heat-conducting rod 200 can flow out. When the heat pump system is working, the heat-conducting rod 200 will transfer heat. The fan 600 inhales air through the air inlet 701, and the air flows through the inner side end of the heat-conducting rod 200, exchanges heat with the heat dissipation fins, and then sends the regulated temperature air into the decompression chamber through the air outlet 702. The fan 600 driven by the magnetic coupling motor can more efficiently transfer the heat on the heat-conducting rod 200 to the decompression chamber, thereby improving the overall temperature regulation efficiency. Since there is no physical contact between the rotor and the stator of the magnetic coupling motor, there is no friction and sparks, which is very important for application scenarios such as decompression chambers where flammable gases or high-pressure environments may exist.

[0033] In another preferred embodiment, a temperature control switch is provided in the cavity 1 305, and the temperature control switch is connected to the power line of the magnetic coupling motor. The temperature control switch can automatically turn on or off the power of the magnetic coupling motor according to the set temperature range, so as to realize automatic adjustment of the temperature in the cabin. Through automatic control, the system only runs when necessary, thereby reducing energy waste and improving overall energy efficiency. The automatic control system can be adjusted according to different decompression chamber sizes and usage conditions, and has good adaptability.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
