[0070] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0072] In addition, it needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "set", "connected", "communicated" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be mechanically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0073] Firstly, refer to Figures 1-7 The cooling equipment with condensing and air cooling functions of the present application is described.

[0074] In order to solve the problem of complexity of the generator cooling system, difficulty of maintenance and increase of cost caused by the two independent cooling circuits for cooling the air cooling medium and the condensing medium, the cooling equipment with condensing and air cooling functions of the present application comprises a cooling body 1 and a heat exchange mechanism. The cooling body 1 has two independent air cooling areas 12 and condensing areas 11 inside, and the cooling body 1 is provided with an air cooling inlet and an air cooling outlet communicated with the air cooling area 12, and a working medium inlet 111 and a working medium outlet 112 communicated with the condensing area 11. Part of the heat exchange mechanism is arranged in the air cooling area 12, and the other part is arranged in the condensing area 11.

[0075] The present application sets two independent air cooling areas 12 and condensing areas 11 inside the cooling body 1, and sets part of the heat exchange mechanism in the air cooling area 12 and the other part in the condensing area 11, integrates the air cooling circuit for cooling the air cooling medium and the condensing circuit for cooling the condensing medium into the same cooling circuit, so that the same circulating cooling liquid can cool the air cooling medium and the condensing medium at the same time, thereby simplifying the equipment structure, reducing the difficulty and cost of maintenance, and avoiding the problem of increasing the number of pipes, joints and other components caused by using two independent cooling circuits to cool the air cooler and the condenser.

[0076] Further refer to Figures 1-7 A preferred embodiment of the cooling equipment with condensing and air cooling functions of the present application is introduced. Those skilled in the art can understand that the following embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Under the premise of meeting the requirement that the cooling equipment at least comprises a cooling body 1 and a heat exchange mechanism, those skilled in the art can adjust the following setting modes so that the present application can be applied to more specific application scenarios.

[0077] Among them, the present application takes the cooling liquid as the cooling water, the air cooling medium as the air, and the condensing medium as the phase change working medium as an example for illustration.

[0078] Refer to Figures 1-7The cooling device includes a cooling body 1 and a heat exchange mechanism. The cooling body 1 has a receiving space, which is divided by a partition plate 13 into a non-communicating air-cooled region 12 and a condensation region 11. The condensation region 11 is located above the air-cooled region 12. Part of the heat exchange mechanism is located in the air-cooled region 12, and another part is located in the condensation region 11. The cooling body 1 corresponding to the condensation region 11 is provided with a working fluid inlet 111 and a working fluid outlet 112. The working fluid inlet 111 is located above the working fluid outlet 112, and both the working fluid inlet 111 and the working fluid outlet 112 are connected to the condensation region 11, so that after the gaseous working fluid enters the condensation region 11 through the working fluid inlet 111, it exchanges heat with the heat exchange mechanism and becomes a liquid working fluid, which flows out through the working fluid outlet 112. The cooling body 1 corresponding to the air-cooled region 12 is provided with an air-cooled inlet and an air-cooled outlet, which are connected to the air-cooled region 12. After the high-temperature air enters the air-cooled region 12 through the air-cooled inlet, it exchanges heat with the heat exchange mechanism and is then discharged through the air-cooled outlet, thus enabling the heat exchange mechanism to cool both the high-temperature air and the gaseous working fluid simultaneously.

[0079] Of course, the positional relationship between the air-cooled region 12 and the condensation region 11 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the air-cooled region 12 can be positioned above the condensation region 11. Alternatively, the air-cooled region 12 and the condensation region 11 can be arranged sequentially along the length of the cooling body 1.

[0080] See next Figures 1-7 The heat exchange mechanism includes multiple heat exchange tubes 2, all of which are along the height direction of the cooling body 1 (e.g., ...). Figures 1-7 Extending in the Z direction (as shown), and along the length direction of the cooling body 1 (e.g., Figures 1-7 The X-axis direction is shown in the diagram. Each heat exchange tube 2 is linear, with one part located in the air-cooling region 12 and the other part located in the condensation region 11. The heat exchange tube 2 located in the air-cooling region 12 can cool the high-temperature air, while the heat exchange tube 2 located in the condensation region 11 can cool the gaseous working fluid.

[0081] It should be noted that this application does not limit the shape or cross-sectional shape of the heat exchange tube 2, as long as the heat exchange tube 2 located in the air-cooling region 12 can cool the high-temperature air and the heat exchange tube 2 located in the condensation region 11 can cool the gaseous working fluid. For example, the heat exchange tube 2 can be arranged in a curved or zigzag shape within the cooling body 1. And / or, the cross-sectional shape of the heat exchange tube 2 can be circular, elliptical, or other shapes.

[0082] See next Figures 3-7The heat exchange tubes 2 located in the condensation zone 11 are all provided with micro-rough structures 23. The micro-rough structures 23 can increase the roughness of the surface of the heat exchange tubes 2, reduce the contact area between the liquid working medium and the heat exchange tubes 2 after heat exchange, thereby promoting the separation of the liquid working medium from the surface of the heat exchange tubes 2 and effectively preventing scaling.

[0083] It should be noted that this application does not limit the micro-roughness structure 23, as long as it can reduce the contact area between the liquid working fluid and the surface of the heat exchange tube 2. For example, the micro-roughness structure 23 can be a convex structure or a concave structure. When the micro-roughness structure 23 is a convex structure, the convex structure is a micrometer-scale convex structure, which can be pyramidal. When the micro-roughness structure 23 is a concave structure, the concave structure is a micrometer-scale concave structure, which can be a V-groove.

[0084] Furthermore, this application does not limit the formation method of the micro-rough structure 23, as long as the micro-rough structure 23 can be formed on the surface of the heat exchange tube 2. For example, micro-nano structure arrays formed by laser micromachining, photolithography and other means, or surface coatings made of materials such as nano-silver and graphene can all achieve micron-level rough structures.

[0085] See next Figures 1-7 A first fin structure 21 is provided on the heat exchange tube 2 located in the condensation region 11. The first fin structure 21 is an intermittent fin, comprising multiple fins along the length of the heat exchange tube 2 (e.g., ...). Figures 1-3 The first fins (shown in the vertical direction) are spaced apart and toothed. Each first fin includes multiple smaller first fins, which are spaced apart circumferentially along the heat exchange tube 2 to form a toothed shape. These toothed first fins are umbrella-shaped. By providing multiple first fins on the heat exchange tube 2, the cooling effect of the gaseous working fluid can be effectively improved. A second fin structure 22 is provided on the heat exchange tube 2 located in the air-cooled region 12. The second fin structure 22 is also an intermittent fin structure, which includes multiple second fins spaced apart along the length of the heat exchange tube 2 and arranged in a ring shape. These second fins are straight. By providing multiple second fins on the heat exchange tube 2, the cooling effect of the high-temperature air can be improved.

[0086] Of course, the specific configuration of the first fin structure 21 in this application is not fixed, and those skilled in the art can adjust it as needed. For example, when the first fin structure 21 is an intermittent fin, the toothed first fin can also be straight or spiral, or the first fin can also be annular. Alternatively, the first fin structure 21 can also be a continuous fin. When the first fin structure 21 is a continuous fin, the continuous fin can be spiral or wavy. Wherein, when the continuous fin is wavy, the wavy fin structure can include a plurality of first small fins spaced apart along the circumference of the heat exchange tube 2, each first small fin extending along the length of the heat exchange tube 2, and the plurality of first small fins connected end to end to form a wave.

[0087] Of course, the specific form of the second fin structure 22 is not fixed in the present application, and those skilled in the art can adjust it according to needs. For example, when the second fin structure 22 is an intermittent fin, the annular second fin can also be in the form of an umbrella, a spiral, or the like. Alternatively, the second fin can also be in the form of a tooth. Alternatively, the second fin structure 22 can also be a continuous fin. When the first fin structure 21 is a continuous fin, the continuous fin can be in the form of a spiral or a wave.

[0088] Next, referring to Figure 3 The cooling device further comprises two cooling boxes, i.e., a first cooling box 3 and a second cooling box 4, which are arranged on both sides of the cooling body 1 in the height direction, and the first cooling box 3 is arranged above the second cooling box 4. Two first partitions 31 are arranged in the first cooling box 3 and spaced apart along the length direction of the cooling body 1, and the first cooling box 3 is divided into three first compartments 32. The second cooling box 4 is provided with a cooling liquid inlet 41 and a cooling liquid outlet 42, and three second partitions 43 are arranged in the second cooling box 4 and spaced apart along the length direction of the cooling body 1, and the second cooling box 4 is divided into four second compartments 44. The two first partitions 31 and the three second partitions 43 are arranged in a staggered manner along the length direction of the cooling body 1, so that the projection of the first compartment 32 in the height direction covers two adjacent second compartments 44. Except that only one heat exchange pipe 2 is connected to the second compartment 44 provided with the cooling liquid inlet 41 and the cooling liquid outlet 42, and the other end of the heat exchange pipe 2 communicates with the corresponding first compartment 32 on the second compartment 44, the remaining second compartments 44 are each provided with two heat exchange pipes 2, and the other ends of the two heat exchange pipes 2 respectively communicate with two adjacent first compartments 32 above and below the second compartment 44, so that the six heat exchange pipes 2 are connected in series through the first compartments 32 and the second compartments 44 to form a cooling liquid channel, and the cooling liquid channel is in the shape of S. The first end of the cooling liquid channel communicates with the second compartment 44 on the leftmost side, and the second end communicates with the second compartment 44 on the rightmost side, so that the cooling water enters the second compartment 44 on the leftmost side through the cooling liquid inlet 41, the cooling water in the second compartment 44 flows into the first compartment 32 on the leftmost side through the heat exchange pipe 2 connected thereto, the cooling water in the first compartment 32 flows into the second compartment 44 close to the leftmost side through the other heat exchange pipe 2 connected to the first compartment 32, and the cooling water in the second compartment 44 flows into the first compartment 32 close to the leftmost side through the other heat exchange pipe 2 connected to the second compartment 44, and so on, until the cooling water flows into the second compartment 44 on the rightmost side and flows out from the cooling liquid outlet 42. The cooling water can cool the phase-change working medium in the condensation area 11 and the high-temperature air in the air-cooling area 12 during the flow process in the S-shaped cooling liquid channel.

[0089] Of course, the number of heat exchange pipes 2 is not fixed in the present application, and those skilled in the art can adjust it according to the needs. For example, 2, 3, 4 or other numbers of heat exchange pipes 2 can be independently arranged on each second compartment 44. Among them, in addition to the heat exchange pipes 2 on the second compartment 44 provided with the cooling liquid inlet 41 and the cooling liquid outlet 42 only communicating with one first compartment 32, the heat exchange pipes 2 on the rest of the second compartments 44 can be divided into two parts, i.e. the first part and the second part, and the two parts are respectively communicated with two adjacent first compartments 32. The number of heat exchange pipes 2 in the first part can be the same as or different from the number of heat exchange pipes 2 in the second part, as long as the cooling liquid passage formed by the plurality of heat exchange pipes 2 is S-shaped as a whole.

[0090] Secondly, the number of first partitions 31 in the first cooling box 3 and the number of second partitions 43 in the second cooling box 4 are not fixed in the present application, and those skilled in the art can adjust them according to the needs. For example, the number of first partitions 31 and the number of second partitions 43 are the same, for example, the number of first partitions 31 and the number of second partitions 43 are 1, 2, 3 or other numbers. Or the number of first partitions 31 can also be different from the number of second partitions 43, for example, the number of first partitions 31 is one more than the number of second partitions 43, or the number of first partitions 31 is one less than the number of second partitions 43. Figure 4 When the number of first partitions 31 is the same as the number of second partitions 43, for example, the number of first partitions 31 and the number of second partitions 43 are 2, as shown in FIG. 4, in addition to the heat exchange pipes 2 on the second compartment 44 provided with the cooling liquid inlet 41 only communicating with one first compartment 32 and the heat exchange pipes 2 on the first compartment 32 provided with the cooling liquid outlet 42 only communicating with one second compartment 44, the heat exchange pipes 2 on the rest of the compartments are divided into two parts, and the other ends of the two parts are respectively communicated with two adjacent compartments. Figure 5 When the number of first partitions 31 is one more than the number of second partitions 43, for example, the number of first partitions 31 is 3 and the number of second partitions 43 is 2, as shown in FIG. 5, in addition to the heat exchange pipes 2 on the first compartment 32 provided with the cooling liquid inlet 41 and the cooling liquid outlet 42 only communicating with one second compartment 44, the heat exchange pipes 2 on the rest of the second compartments 44 can be divided into two parts, and the other ends of the two parts are respectively communicated with two adjacent second compartments 44.

[0091] Furthermore, the formation method of the S-shaped coolant channel is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the number of first compartments 32 and second compartments 44 is the same and they correspond one-to-one vertically. Figure 6 As shown, a heat exchange tube 2 is provided between the first compartment 32 and the corresponding second compartment 44. Since the coolant inlet 41 is connected to the rightmost second compartment 44, the first cooling tank 3 has a first connecting hole 311 on the odd-numbered first partition 31 in the direction from left to right, and the second cooling tank 4 has a second connecting hole 431 on the even-numbered second partition 43 in the direction from left to right. This allows the two ends of the multiple heat exchange tubes 2 to be connected through the corresponding two compartments, thereby forming an S-shaped coolant channel. The first compartment 32, heat exchange tube 2, and second compartment 44 are arranged from left to right. The flow path of the cooling water is described as follows: the cooling water flows into the first second compartment 44 through the coolant inlet 41, and then flows into the first first compartment 32 through the first heat exchange tube 2. The cooling water in the first compartment then flows into the second first compartment 32 through the first connecting hole 311 on the first first partition 31. The cooling water in the second compartment then flows into the second second compartment 44 through the second heat exchange tube 2. The cooling water in the second compartment then flows into the third second compartment 44 through the second connecting hole 431 on the second second partition 43. This cycle continues until the cooling water flows out from the coolant outlet 42.

[0092] Furthermore, the specific shape of the coolant passage is not fixed and can be adjusted as needed by those skilled in the art. For example, the coolant passage can also be the shape of the heat exchange tube 2, that is, multiple heat exchange tubes 2 no longer connect end to end to form an S-shaped meandering flow channel, but instead, one end of the heat exchange tube 2 serves as the inlet end of the cooling water and the other end as the outlet end, forming a unidirectional flow channel. In this case, if the heat exchange tube 2 is straight, the coolant passage is straight; or if the heat exchange tube 2 is curved, the coolant passage is curved; or if the heat exchange tube 2 is zigzag, the coolant passage is zigzag. Here, we will explain the case where the heat exchange tube 2 is straight, for example... Figure 7 As shown, neither the first cooling tank 3 nor the second cooling tank 4 is equipped with a partition. The first cooling tank 3 is equipped with a coolant outlet 42, and the second cooling tank 4 is equipped with a coolant inlet 41. The two cooling tanks are used to connect the two ends of the heat exchange tubes 2, so that cooling water enters the first cooling tank 3 through the coolant inlet 41. The cooling water in the first cooling tank 3 can flow into the second cooling tank 4 through all the heat exchange tubes 2 at the same time, and finally flow out from the coolant outlet 42. This also enables the heat exchange tubes 2 located in the air-cooled region 12 to cool the high-temperature air, and the heat exchange tubes 2 located in the condensation region 11 to cool the gaseous working fluid.

[0093] Combination Figure 3 The working process of the cooling equipment in this application is described as follows:

[0094] During the circulation of the cooling water in the S-shaped cooling water channel, the gas-phase working medium enters the condensation area 11 from the working medium inlet 111, contacts the heat exchange tube 2 and the first fin structure 21 in the condensation area 11, transfers heat to the cooling water flowing in the heat exchange tube 2, and condenses into liquid-phase working medium, which drips down along the fin or flows down along the tube, is collected at the bottom of the condensation area 11, and finally flows out through the working medium outlet 112.

[0095] The high-temperature air enters the air cooling area 12 from the air cooling inlet, contacts the heat exchange tube 2 and the second fin structure 22 in the air cooling area 12 during the flow in the air flow channel 24, transfers heat to the cooling water flowing in the heat exchange tube 2, and becomes low-temperature air, which flows out from the air cooling outlet.

[0096] During the flow of the cooling water in the first cooling tank 3, the heat exchange tube 2 and the second cooling tank 4, the cooling water exchanges heat with the high-temperature air of the air flow channel 24 and the phase-change working medium of the condensation area 11, absorbs heat and becomes high-temperature water, which flows out through the cooling water outlet 42, so that the same heat exchange mechanism can simultaneously cool the phase-change working medium and the high-temperature air.

[0097] In addition, the utility model also provides a cooling system, the cooling system is the cooling equipment of any preceding embodiment.

[0098] It should be noted that the cooling system has all the technical effects of the foregoing cooling equipment, which will not be repeated here.

[0099] In addition, the utility model also provides a generator, the generator includes the cooling equipment of any preceding embodiment or the cooling system of the foregoing embodiment.
