Description

Technical Field

[0001] The utility model relates to a self-cooling device, in particular to a core machine self-cooling device of a magnetic suspension compressor. Background Art

[0002] In modern industry, magnetic levitation compressors are highly favored for their significant advantages, including high efficiency, energy saving, and low noise. However, as their performance continues to improve and their application expands, the heat dissipation of their core engines has become a key factor restricting their further development.

[0003] During operation, the core engine of a magnetic levitation compressor generates a significant amount of heat due to its internal high-speed rotating components and electromagnetic conversion processes. If this heat cannot be dissipated promptly and effectively, the core engine temperature will rise sharply. Excessive temperatures not only affect the mechanical properties and service life of the core engine's internal components, but can also cause thermal deformation and thermal stress, reducing the compressor's operating efficiency and stability, and even causing compressor failure and shutdown, severely impacting production and operation.

[0004] In the prior art, common cooling methods for the core engine of magnetic levitation compressors mainly include air cooling and water cooling. The air cooling method usually uses a fan to blow cold air from the outside to the core engine for heat dissipation, but this method is limited by the ambient temperature and air flow speed, and the cooling effect is limited. Especially in high temperature environments or high-load operating conditions, it is difficult to meet the heat dissipation needs of the core engine. The water cooling method uses circulating water to take away the heat of the core engine (the water cooling method can only reduce the temperature of the stator), but there are problems such as complex system, high risk of pipeline leakage, and high maintenance cost. As magnetic levitation compressors develop towards miniaturization and high efficiency, traditional cooling devices have gradually become difficult to adapt to new requirements. The development of a high-efficiency, compact core engine self-cooling device has become an important issue that needs to be urgently solved in the current field of magnetic levitation compressor technology.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a core engine self-cooling device for a magnetic levitation compressor, which has the following beneficial effects:

[0018] 1. Through efficient air intake and intercooler cooling, a stable low-temperature environment is maintained for the core engine, reducing internal energy loss and frictional resistance. This enables the compressor to operate at higher speeds and more stable performance, significantly improving efficiency. For example, at the same power input, a magnetic levitation compressor with a core engine self-cooling structure can achieve significantly higher cooling capacity and exhaust volume than a traditional structure.

[0019] 2. The stable low-temperature environment effectively controls the thermal expansion and contraction of core engine components, reducing deformation and wear caused by temperature fluctuations. This significantly reduces the probability of failure and enables the compressor to maintain stable operation for a long time. For example, after hundreds of hours of continuous operation, various performance indicators can still fluctuate within normal ranges, while traditional compressors may experience performance degradation or failure.

[0020] 3. In harsh environments such as high temperature and high humidity, the core unit's self-cooling structure ensures the normal operation of the compressor without being excessively affected by the external ambient temperature. For example, in the hot summer or in a high-temperature workshop, it can still stably provide the required refrigeration or compressed gas.

[0021] 4. Higher working efficiency means less energy is consumed at the same output, reducing energy consumption and carbon emissions. In addition, stable operation reduces the additional energy waste caused by failures and inefficient operation, which is in line with the development trend of energy conservation and environmental protection.

[0022] 5. By utilizing the characteristics of the intercooler, a fan dedicated to motor heat dissipation was successfully eliminated, thereby reducing costs. At the same time, this improvement significantly improved the space efficiency of the compressor, making the structure more compact, which further reduced the cabinet cost.

[0023] 6. This innovative core engine self-cooling structure gives the magnetic levitation compressor obvious advantages in performance, reliability and energy saving, enhances the product's competitiveness in the market, and can meet the needs of more high-end users.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The utility model provides a new technical solution:

[0037] A core engine self-cooling device for a magnetic levitation compressor, the core engine self-cooling device comprising a core engine 1, an intercooler 2, a first-stage impeller 8, a second-stage impeller 9, an air inlet 10, and an air outlet 11, the core engine 1 being provided with an air inlet 10 and an air outlet 11, the first-stage impeller 8 being provided at the air inlet 10, the first-stage impeller 8 being used to guide air to the intercooler 2, the first-stage impeller 8 being connected to the input end of the intercooler 2 below, the intercooler 2 being used to cool the incoming air, the output end of the intercooler 2 being connected to the air outlet 11, the second-stage impeller 9 being provided at the air outlet 11, the second-stage impeller 9 being used to guide the air output by the intercooler 2 to the air outlet 11.

[0038] In this embodiment, the core engine self-cooling device of the magnetic levitation compressor also includes a cyclone steam-water separator 3, which connects the core engine 1 and the intercooler 2. The cyclone steam-water separator 3 is used to separate the water vapor generated by the cold air after cooling by the intercooler 2.

[0039] In this embodiment, the core engine self-cooling device of the magnetic levitation compressor also includes a connecting unit, which includes a bellows 4 and a cyclone steam-water separator bellows 5. The bellows 4 connects the core engine 1 and the intercooler 2, and the cyclone steam-water separator bellows 5 connects the core engine 1, the cyclone steam-water separator 3 and the intercooler 2.

[0040] In this embodiment, a base 12 is provided at the bottom of the intercooler 2 .

[0041] In this embodiment, both the first-stage impeller 8 and the second-stage impeller 9 are three-dimensional flow impellers.

[0042] In this embodiment, a base 12 is provided at the bottom of the intercooler 2 .

[0043] In this embodiment, the cyclone steam-water separator bellows 5 includes a first-section cyclone steam-water separator bellows 6 and a second-section cyclone steam-water separator bellows 7. The first-section cyclone steam-water separator bellows 6 is arranged at the left end of the cyclone steam-water separator 3, the upper end is arranged at the core engine 1, and the lower end is arranged at the left side of the cyclone steam-water separator 3. The second-section cyclone steam-water separator bellows 7 is arranged at the right end of the cyclone steam-water separator 3, the upper end is arranged at the right side of the cyclone steam-water separator 3, and the lower end is arranged at the intercooler 2.

[0044] In this embodiment, the first section cyclone steam-water separator bellows 6 is "L" shaped when viewed from the front, the second section cyclone steam-water separator bellows 7 is "L" shaped when viewed from the right, and the bellows 4 is "U" shaped when viewed from the front.

[0045] Working Principle: First, driven by the efficient rotation of the first-stage three-dimensional flow impeller 8, air is directed to the inlet of the intercooler 2, where it is then cooled and discharged smoothly from its outlet. The seamless connection between the bellows 4 and the volute ensures smooth air circulation, and then flows to the second-stage three-dimensional flow impeller 9 for further compression.

[0046] During this process, we specifically added a port at the outlet of intercooler 2 to cool the core engine 1. However, since the gas cooled by intercooler 2 may contain a certain amount of moisture, using it directly to cool the core engine 1 poses a potential risk of damage. Therefore, we cleverly installed a cyclone-type steam-water separator 3 at the port. This device can efficiently separate 99% of the moisture in the gas, effectively cooling the core engine 1 while effectively preventing damage caused by moisture.

[0047] This design is made possible by the intercooler's exceptional cooling performance, ensuring the air temperature after the first stage of compression is consistently reduced to approximately 30°C. This characteristic is fully utilized to not only provide efficient and safe cooling for the core engine, but also further simplify the structure by eliminating a fan specifically designed for motor heat dissipation, significantly improving the compressor's operating efficiency and stability.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
