[0020] The compressor 100,

[0022] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below are exemplary only, and are not intended to limit the present application.

[0023] Reference is made below to Figures 1-2 A compressor according to an embodiment of the present application is described below, which can save space, reduce manufacturing cost, realize sufficient heat exchange between air flow and water flow, and save energy.

[0024] As shown in the drawings, a compressor 100 according to an embodiment of the present application comprises a body 11 and a condenser 12. Figures 1-2

[0025] The body 11 is provided with an air inlet 111, and the condenser 12 is integrally arranged with the body 11. The condenser 12 is provided with an air outlet 121, a water inlet 122 and a water outlet 123. The air inlet 111 and the air outlet 121 are communicated through an air flow passage 124, and the water inlet 122 and the water outlet 123 are communicated through a water flow passage 125. The air flow in the air flow passage 124 and the water flow in the water flow passage 125 are adapted to exchange heat in the condenser 12.

[0026] Specifically, the air inlet 111 of the compressor 100 is arranged at one side of the body 11, and the condenser 12 is arranged on the body 11. The condenser 12 is integrally arranged with the body 11. The air outlet 121 of the compressor 100 is arranged at one side of the condenser 12. The water inlet 122 and the water outlet 123 of the condenser 12 are also arranged on the condenser 12. The air flow passage 124 and the water flow passage 125 are arranged in the condenser 12. The starting end of the air flow passage 124 is communicated with the air inlet 111 arranged on the body 11. The end of the air flow passage 124 is communicated with the air outlet 121 arranged on the condenser 12. The starting end of the water flow passage 125 is communicated with the water inlet 122 arranged on the condenser 12. The end of the water flow passage 125 is communicated with the water outlet 123 arranged on the condenser 12.

[0027] ​Further, the compressor 100 is used for compressing gas, the compressed gas enters from the gas inlet 111 arranged on the body 11, is transported to the inside of the body 11 through the airflow channel 124, is compressed into high-temperature and high-pressure gas by the compressor 100, and then flows through the condenser 12 through the airflow channel 124. Meanwhile, the low-temperature liquid flows into the condenser 12 from the water inlet 122 arranged on the condenser 12, enters the inside of the condenser 12 through the water flow channel 125, and flows through the water flow channel 125 when the high-temperature and high-pressure gas flows through the airflow channel 124. The high-temperature and high-pressure gas in the airflow channel 124 and the low-temperature liquid in the water flow channel 125 have a temperature difference to adapt to heat exchange in the condenser 12. The low-temperature liquid in the water flow channel 125 can absorb the temperature of the high-temperature and high-pressure gas in the airflow channel 124 to reduce the temperature of the gas. Because the airflow channel 124 and the water flow channel 125 are arranged in the condenser 12 and are close to each other, the heat exchange effect is better.

[0028] According to the compressor 100 of the embodiment of the present application, the condenser 12 is arranged in the body 11, the connecting pipeline is reduced, the space is saved, the manufacturing cost is saved, the airflow channel 124 and the water flow channel 125 are arranged in the condenser 12, the airflow channel 124 and the water flow channel 125 are close to each other, sufficient heat exchange between the airflow and the water flow can be realized, the energy is saved, the use effect is better, and the application range is wider.

[0029] In some embodiments, the airflow channel 124 includes a first part and a second part. The first part is formed in the body 11 and communicates with the gas inlet 111. The second part is formed in the condenser 12 and communicates with the gas outlet 121. The extension direction of the second part is parallel to the extension direction of at least part of the water flow channel 125.

[0030] Specifically, the airflow channel 124 includes a first part and a second part. The first part communicates with the second part. The first part is the front section, i.e., the starting end, of the airflow channel 124, is formed in the body 11, and communicates with the gas inlet 111 arranged on the body 11. The second part is the rear section, i.e., the end, of the airflow channel 124, is formed in the condenser 12, and communicates with the gas outlet 121 arranged on the condenser 12. Arranging part of the airflow channel 124 in the condenser 12 can save space and save manufacturing cost.

[0031] Further, the gas enters the air inlet 111 provided on the body 11, is transported to the inside of the body 11 through the first part of the airflow channel 124, is compressed into high-temperature and high-pressure gas by the compressor 100, and then flows through the second part of the airflow channel 124 in the condenser 12. The condenser 12 is also provided with a water flow channel 125, and low-temperature liquid flows through the water flow channel 125. The extension direction of the second part of the airflow channel 124 is parallel to the extension direction of at least part of the water flow channel 125. When the extension direction of the second part of the airflow channel 124 through which the high-temperature and high-pressure gas flows is parallel to the extension direction of the water flow channel 125 through which the low-temperature liquid flows, the heat exchange area can be maximized, and the heat exchange effect is better, thereby saving energy.

[0032] In some embodiments, the extension direction of the second part is perpendicular to the air inlet direction of the air inlet 111, and the second part of the airflow channel 124 is provided in the condenser 12. The gas enters the air inlet 111 of the airflow channel 124, is compressed into high-temperature and high-pressure gas in the body 11, and then is transported through the second part of the airflow channel 124. Therefore, the gas pressure in the second part of the airflow channel 124 is higher than the gas pressure in the first part of the airflow channel 124. By setting the extension direction of the second part of the airflow channel 124 to be perpendicular to the air inlet direction of the air inlet 111, the backflow of the high-temperature and high-pressure gas in the second part of the airflow channel 124 to the first part of the airflow channel 124 can be avoided to some extent, and the effectiveness of gas transportation is ensured.

[0033] In some embodiments, the water flow channel 125 includes a plurality of sub-flow channels. The plurality of sub-flow channels are parallel and spaced apart in the condenser 12, and adjacent two sub-flow channels are connected through an end flow channel, that is, the plurality of sub-flow channels of the water flow channel 125 and the two adjacent sub-flow channels form an "S"-shaped water flow channel 125.

[0034] Specifically, the high-temperature and high-pressure gas in the second part of the airflow channel 124 exchanges heat with the low-temperature liquid in the water flow channel 125 through the temperature difference. The closer the distance between the airflow channel 124 and the water flow channel 125, the larger the heat exchange area, and the longer the heat exchange time, and the better the heat exchange effect.

[0035] Further, the water flow channel 125 is arranged in the condenser 12, and the water flow channel 125 is formed in the condenser 12 in an "S" shape by a plurality of parallel and spaced sub-flow channels and end flow channels for connecting adjacent two sub-flow channels, so that the low-temperature liquid in the adjacent two sub-flow channels of the water flow channel 125 can flow back and forth, the length of the water flow channel 125 is maximized in the limited space, and when the high-temperature and high-pressure gas in the second part of the air flow channel 124 exchanges heat with the low-temperature liquid in the water flow channel 125, the low-temperature liquid has a longer flow time in the water flow channel 125, and the heat exchange effect is better. In addition, the water flow channel 125 is designed in a segmented manner, which can slow down the flow speed of the low-temperature liquid, further increase the flow time of the low-temperature liquid in the water flow channel 125, and improve the heat exchange effect.

[0036] In some embodiments, as shown in Figures 1-2 The condenser 12 is configured in a fan shape, and the plurality of sub-flow channels are arranged in a fan shape in the circumferential direction of the condenser 12.

[0037] Specifically, in the present embodiment, the machine body 11 is a cylindrical machine body 11, and the condenser 12 is integrated on the machine body 11, and the condenser 12 is configured in a fan shape. The fan-shaped curvature of the condenser 12 matches the machine body 11, so that the shape of the condenser 12 is more consistent with the machine body 11 when it is integrated on the machine body 11. In addition, this arrangement method makes the space occupied by the condenser 12 when it is integrated on the machine body 11 small, saving manufacturing costs.

[0038] At the same time, as shown in Figure 1 The water flow channel 125 arranged in the condenser 12 includes a plurality of sub-flow channels, and the plurality of sub-flow channels are arranged in a fan shape in the circumferential direction of the condenser 12. In addition, due to the fan-shaped structure of the condenser 12, the plurality of sub-flow channels are arranged in a fan shape in the circumferential direction of the condenser 12, thereby fully utilizing the internal space of the condenser 12, arranging more water flow channels 125 in a certain space, thereby prolonging the length of the water flow channel 125. When the high-temperature and high-pressure gas in the second part of the air flow channel 124 exchanges heat with the low-temperature liquid in the water flow channel 125, the plurality of sub-flow channels arranged in the circumferential direction of the condenser 12 can prolong the flow time of the low-temperature liquid in the water flow channel 125, and the heat exchange effect is better.

[0039] In some embodiments, as shown in Figure 1As shown, the plurality of sub-flow channels are arranged in multiple rows and multiple columns in the condenser 12, which can arrange multiple sub-flow channels in the limited space of the condenser 12, prolong the flow distance and flow time of the low-temperature liquid in the condenser 12, improve the heat exchange effect, and the distribution between the sub-flow channels is more uniform. The second part of the airflow passage 124 is correspondingly arranged in the condenser 12, which can ensure that the second part of the airflow passage 124 can exchange heat with the sub-flow channels, so that the heat exchange is more uniform, and the heat exchange effect is guaranteed.

[0040] In some embodiments, the extension direction of the sub-flow channel is parallel to the extension direction of at least part of the airflow passage 124, as explained in the Figure 1 extension direction of the sub-flow channel is parallel to the extension direction of the straight part of the airflow passage 124. After the gas is compressed into high-temperature and high-pressure gas by the compressor 100, it flows through the second part of the airflow passage 124 in the condenser 12, and the sub-flow channel of the water flow passage 125 in the condenser 12 flows through the low-temperature liquid. The extension direction of the second part of the airflow passage 124 is parallel to the extension direction of at least part of the sub-flow channel. When the extension direction of the second part of the airflow passage 124 through which the high-temperature and high-pressure gas flows is parallel to the extension direction of the sub-flow channel through which the low-temperature liquid flows, the heat exchange area can be maximized, the heat exchange effect is better, energy is saved, and in some embodiments, as shown in Figure 1 the extension direction of the second part can be the same as the extension direction of the water flow passage.

[0041] In some embodiments, the gas outlet 121, the water inlet 122, and the water outlet 123 are all located on the same end face of the condenser 12 away from the air inlet 111, as shown in Figure 1 and Figure 2 As shown, the gas outlet 121, the water inlet 122, and the water outlet 123 are all located on the right end face of the condenser 12 away from the air inlet 111, and in this embodiment, the gas outlet 121 and the water inlet 122 are arranged on one end of the end face of the condenser 12 and are closer to the air inlet 111, and the water outlet 123 is arranged on the other end of the end face of the condenser 12 and is farther away from the air inlet 111.

[0042] Specifically, gas enters the body 11 through the first part of the airflow channel 124 after passing through the inlet 111, where it is compressed. The compressed high-temperature, high-pressure gas then flows through the second part of the airflow channel 124 into the condenser 12. The second part begins below the outlet 123 in the condenser 12, i.e., it is located on the same side as the outlet 123 located on the end face of the condenser 12. It is connected to the body 11. The high-temperature, high-pressure gas is compressed by the body 11 and then transferred to the second part. Therefore, the high-temperature, high-pressure gas flows from the condenser 12... The water flows from the outlet 123 side of the end face to the inlet 122 side of the condenser 12 end face, and then is discharged from the outlet 121. The low temperature liquid flows in from the inlet 122, flows through the water flow channel 125 and then flows out from the outlet 123 of the condenser 12. The low temperature liquid is low when it first enters the water flow channel 125, and the heat exchange effect is good. The high pressure gas here has absorbed a lot of heat, and after absorbing heat again through the low temperature liquid here, it is discharged, which makes the heat exchange effect better and ensures that the temperature of the discharged gas reaches the set value.

[0043] In some embodiments, such as Figure 1 As shown, the condenser 12 is integrated above the body 11 and is integrally formed with the body 11. The gas is compressed into high-temperature and high-pressure gas by the body 11 and then transported to the condenser 12. Heat exchange occurs through the low-temperature liquid in the condenser 12, which lowers the gas temperature. The gas is then output through the outlet 121. Integrating the condenser 12 above the body 11 saves on the pipes connecting the compressor 100 and the condenser 12, thus saving manufacturing costs. At the same time, the condenser 12 and the body 11 are integrally formed, which saves space. The water flow channels 125 in the condenser 12 are arranged in the condenser 12, so they are all arranged above the body 11. When the body 11 generates heat during operation, the condenser 12 can also cool the body 11, thereby keeping the compressor 100 within the required speed range and avoiding problems such as the compressor 100 exceeding the minimum power setting value, which could lead to system malfunctions.

[0044] In some embodiments, the air outlet 121 has an air outlet direction, the water inlet 122 has a water inlet direction, and the water outlet 123 has a water outlet direction that are parallel to each other and perpendicular to the air inlet 111.

[0045] Specifically, the air outlet 121 is connected to the end of the second part of the airflow channel 124, the water inlet 122 is connected to the beginning of the water flow channel 125, and the water outlet 123 is connected to the end of the water flow channel 125. The air outlet direction of the air outlet 121, the water inlet direction of the water inlet 122, and the water outlet direction of the water outlet 123 are parallel to each other. That is, the end of the second part of the airflow channel 124, the beginning of the water flow channel 125, and the end of the water flow channel 125 are parallel to each other. This arrangement can maximize the heat exchange area, improve the heat exchange effect, and save energy.

[0046] The air outlet 121, the water inlet 122 and the water outlet 123 are perpendicular to the air inlet 111, the air inlet 111 is communicated with the first part of the airflow channel 124, the first part of the airflow channel 124 is perpendicular to the last section of the second part of the airflow channel 124, the starting section of the water flow channel 125 and the last section of the water flow channel 125, respectively, the high-temperature and high-pressure gas in the machine body 11 is transported through the second part of the airflow channel 124, and the pressure of the gas in the second part of the airflow channel 124 is higher than the pressure of the gas in the first part of the airflow channel 124; the extending direction of the second part of the airflow channel 124 is perpendicular to the air inlet direction of the air inlet 111, which can avoid the high-temperature and high-pressure gas in the second part of the airflow channel 124 from flowing back to the first part of the airflow channel 124 to a certain extent, and ensure the effectiveness of gas transportation.
