Detailed Description

For further explanation of the principles and construction of the present disclosure, reference will now be made in detail to the preferred embodiments of the present disclosure, which are illustrated in the accompanying drawings.

In one embodiment, the present disclosure provides an air conditioning apparatus, which is a unitary machine. Compared with the structure that the inner unit and the outer unit of the traditional air conditioning equipment are independent from each other, in the embodiment, the inner unit and the outer unit of the air conditioning equipment are integrated in the same equipment, namely, the evaporation device and the condensation device are integrated in the same equipment. The all-in-one machine can discharge hot air generated by the all-in-one machine to the outside through the exhaust pipe.

Specifically, referring to fig. 1 and 2, fig. 1 is a schematic perspective view of an air conditioning apparatus according to an embodiment, and fig. 2 is a sectional view of fig. 1, where the air conditioning apparatus 100 includes an evaporation device 10, a condensation device 20, a refrigerant compressor 30, a refrigerant filter 40, and a throttling device 50. The refrigerant compressor 30, the condensing unit 20, the refrigerant filter 40 and the throttling unit 50 are sealed in a hermetic container 101, and the evaporation apparatus 10 is placed outside the hermetic container 101. An air inlet interface 102 and an air outlet interface 103 are arranged on the closed box body 101, the air inlet interface 102 is connected with an air inlet of the condensing device 20, and the air outlet interface 103 is connected with an air outlet of the condensing device 20. An exhaust duct is connected to the exhaust port 103, and the exhaust duct is long enough to extend to the outside of the room to exhaust the hot air after heat exchange with the condensing unit 20. The sealed box 101 is also provided with a control panel 105, and the sealed box 101 is also provided with a control circuit electrically connected to the control panel 105.

The evaporation apparatus 10 and the condensation apparatus 20 are vertically fixed on the same base 104, so that the evaporation apparatus 10 and the condensation apparatus 20 are integrated together to form an integrated machine.

The base 104 and the sealed box 101 may be integrally formed.

Referring to fig. 3, fig. 3 is a cross-sectional view of an air conditioning apparatus in an embodiment, the evaporation device 10 is substantially cylindrical, a fan 61 is disposed at a top end thereof, and an airflow opening 10a for airflow is disposed at a bottom end different from the fan 61. The fan 61 may be a suction fan or a blower. When the fan 61 is a blower, the fan 61 sucks air in the atmosphere from the front end of the evaporator 10 and sends the air into the evaporator 10, and after heat exchange is completed, the air temperature is lowered and the air is blown out from the airflow opening 10a into the room. When the fan 61 is a suction fan, the fan 61 sucks air from the bottom end of the evaporation device 10 through the airflow opening 10a, the sucked air is cooled in the evaporation device 10, and the cooled air finally flows out to the room through the fan outlet at the top end.

It will be appreciated that in one embodiment, the fan 61 may also be located at the bottom end of the evaporator 10, in which case the top end is provided with an airflow opening for airflow to and from.

At least one of the evaporation device 10 and the condensation device 20 includes the heat exchange structure of the present disclosure. The specific structure of the heat exchange structure will be described in detail below by taking the heat exchange structure included in the evaporation apparatus as an example.

Specifically, in an embodiment, as shown in fig. 4 and 5, fig. 4 is a front view of a heat exchange structure of the present disclosure in an embodiment, and fig. 5 is a schematic cross-sectional view along a-a in fig. 4. The heat exchange structure 1a includes a casing 11, a plurality of medium tubes 12 and a plurality of fins 13 provided in the casing 11. The inside of each medium pipe 12 forms a medium flow channel 121.

The housing 11 includes an upper end opening through which air flows in and a lower end opening through which air flows out. Depending on the application, the air flow may also flow in from the lower opening and out from the upper opening of the housing 11. The housing 11 has a circular tubular shape. In other embodiments, the housing 11 may be square tubular or other shapes.

The outer shell 11 can be formed by extrusion with the medium pipe 12 and the fins 13. Furthermore, the outer shell 11 can also be formed separately from the medium tubes 12 and the fins 13, while the medium tubes 12 and the fins 13 are integrally extruded, i.e. the outer shell 11 is slipped on after the medium tubes 12 and the fins 13 have been formed.

The outer shell 11, the medium pipe 12 and the fins 13 may be integrally formed by metal extrusion. The metal may be an aluminum alloy or other material that transfers heat well. The forming mode enables the distribution of the medium tubes 12 and the fins 13 to be more uniform and compact, and compared with a welding forming mode, the size of gaps among the fins 13 can be smaller, so that the heat exchange area is increased to a certain extent, and the heat exchange efficiency is improved; and the integrated into one piece's mode has increased the fashioned precision of device, has reduced the manufacturing degree of difficulty, so can design heat exchange device littleer, reaches the purpose that reduces the volume, satisfies people to miniaturized demand. In addition, the production efficiency can be improved and the cost is reduced by the integrated forming mode.

The heat exchange structure 1a comprises a number of medium tubes 12 arranged in a housing 11. One medium pipe 12 of the plurality of medium pipes 12 is located at the geometric center of the heat exchange device, and the remaining medium pipes 12 are radially distributed around the geometric center. Fins 13 are connected between the medium tubes 12. By arranging the medium pipe 12 in this way, the heat exchange efficiency between the medium in the medium pipe 12 and the fins can be improved, and the temperature rise or reduction amplitude of the air flow is increased. And the provision of a plurality of medium ducts 12 increases the amount of medium entering the heat exchange device, meaning that heat exchange can be carried out with a greater amount of air flow, thereby improving efficiency and reducing time.

It should be noted that the geometric center of the heat exchange structure 1a can be determined according to the cross-sectional shape thereof, for example, in fig. 4 and 5, the heat exchange device is generally cylindrical and has a circular cross-section, and the geometric center thereof is the center of the circular cross-section. For example, if the cross-section of the heat exchanger is square or rectangular, the geometric center thereof is the intersection of two diagonal lines. And so on, and are not illustrated here.

Further, as shown in fig. 5, a plurality of medium pipes 12 are distributed at intervals on a plurality of circumferences with different radiuses by taking the center of the circle of the cross section of the heat exchange structure 1a as the center of the circle. Specifically, the middle medium pipe 12 is taken as a center, the other medium pipes 12 are arranged into a plurality of circumferences with different radiuses, and a plurality of medium pipes 12 are arranged on each circumference at equal intervals or unequal intervals. So arrange, can make medium pipe 12 evenly distributed in each position department of heat transfer structure 1a, and then make the medium in medium pipe 12 can carry out the heat exchange with the air current uniformly, guarantee that the air current temperature after the heat transfer is even.

Each of the medium tubes 12 forms a medium flow channel 121. Due to the arrangement of the medium tubes 12, the medium flow channels 121 can be divided into a plurality of groups, each group of medium flow channels 121 is circumferentially distributed at intervals by taking the center of a circle at the center of the heat exchange structure 1a as the center, and different groups of medium flow channels 121 are distributed on circumferences with different radiuses.

Each medium flow passage 121 extends in the height direction of the housing 11, and penetrates from the upper end of the housing 11 to the lower end of the housing 11. Thereby, the heat exchange efficiency per unit area is increased.

The fins 13 extend in the height direction of the medium pipe 12 and extend from the upper end to the lower end of the medium pipe 12, so that the heat radiation area can be increased and the heat transfer efficiency can be further improved. The fins 13 are attached to the outer wall of each medium pipe 12. In particular, the fins 12 are connected to the geometrically central medium tube 12 and extend in the radial direction thereof, i.e. the fins 12 may extend from the geometrically central medium tube 12 to the outer shell 11.

Specifically, a plurality of fins 13 are provided between the medium flow channels 121 and between the housing 11 and the medium flow channels 121. The fins 13 form gaps 131 therebetween through which the air flows. The fins 13 are radially distributed around the center line of the casing 11 (or the geometrically positioned medium pipe 12), and are uniformly distributed around the outer periphery of each medium flow channel 121. The distribution mode of the fins 13 improves the number of the fins 13 in unit area, increases the integration level of the fins 13 in unit area, and improves the heat transfer efficiency in unit area. The evaporator and/or condenser can thus be designed smaller, which considerably reduces the volume of the air conditioning system.

The medium flow channels 121 may be connected in series or in parallel by connecting pipes. In one embodiment, as shown in fig. 4, the lower end of the housing 11 is provided with a connection pipe 141, and the connection pipe 141 may communicate in parallel with the plurality of medium circulation passages 121 in the radial direction of the housing 11 at the lower end of the housing 11. Referring to fig. 6 and 7, fig. 6 is a plan view of fig. 4, and fig. 7 is a bottom view of fig. 4. The lower end of the housing 11 is provided with a cold medium inlet 151, the cold medium inlet 151 is communicated with the connection pipe 141 at the lower end of the housing 11, and the cold medium flows into the medium circulation passage 121 connected to the connection pipe 141 through the cold medium inlet 151 and the connection pipe 141. The medium flow path 121 not communicated with the connection pipe 141 may be communicated with the medium flow path 121 through which the refrigerant medium is introduced through another connection pipe 142, and finally, the refrigerant medium flows through each medium flow path 121. The lower end of the housing 11 is provided with a refrigerant outlet 152, and the refrigerant in the medium flow passage 121 flows out through the refrigerant outlet 152.

In one embodiment, the heat exchange structure 1a may be provided with a refrigerant inlet and a refrigerant outlet, and the medium flow channels 121 in the housing 11 are sequentially connected in series through connecting pipes.

In one embodiment, each of the media flow channels 121 may be in parallel communication. Specifically, the upper end and the lower end of the shell of the heat exchange structure 1a are respectively provided with an inlet collecting pipe and an outlet collecting pipe. The upper port of each medium flow channel 121 is communicated with the inlet manifold, the lower port of each medium flow channel 121 is communicated with the outlet manifold, and refrigerant medium flows into each medium flow channel 121 from the inlet manifold, flows through each medium flow channel 121, is gathered in the outlet manifold, and finally flows out of the outlet manifold.

The arrangement positions and the number of the cold medium outlets and the cold medium inlets can be changed according to the actual application condition. The communication among the medium circulation channels can be series communication, parallel communication, partial series communication and partial parallel communication.

In addition, the number of the medium circulation channels can be determined according to practical application, and preferably, the number of the medium circulation channels is more than two, so that a better refrigeration effect is achieved.

In another embodiment, as shown in FIG. 8, FIG. 8 is a schematic cross-sectional view of a heat exchange device in another embodiment. The heat exchange structure 1b is integrally extruded and formed, the heat exchange structure 1b is provided with at least one medium flowing channel 161, the outer periphery of the medium flowing channel 161 is provided with a plurality of fins 17, and the fins 17 are mutually spaced to form gaps 18 for air flow to pass through.

The heat exchange structure 1b is cylindrical as a whole and has a circular cross section.

As shown in fig. 8, this heat exchange structure 1b includes a plurality of medium flow channels 161, a part of the medium flow channels 161 being formed by the medium tubes 16, and the other part of the medium flow channels 161 being formed by the fins 17.

The heat exchange structure 1b comprises a medium pipe 16 located at the geometrical centre of the heat exchange structure 1 b. It will be appreciated that the heat exchange structure 1b may comprise a plurality of medium tubes 16, one of which is located in the geometrical centre of the heat exchange structure 1 b. Another part of the medium flow channels 161 formed by the fins 17 are distributed circumferentially around the geometrically central medium tube 16.

A plurality of fins 17 are arranged at intervals on the outer peripheral wall of the medium pipe 16, the fins 17 extending in the height direction of the medium pipe 16 and extending in the radial direction from the medium pipe 16 at the geometric center.

The fins 17 are fork-shaped or pincer-shaped. The forked fin 171 includes a shaft portion 1711 and a bifurcated portion 1712, the shaft portion 1711 being connected to the medium pipe 16 at the geometric center, and the bifurcated portion 1711 being connected to the shaft portion 1712. The pincer-like fins 172 include two opposite shaped

fins

171, 172, the ends of the shaped

fins

171, 172 away from the geometric center are curved, and the curved ends of the shaped

fins

171, 172 enclose the medium flow path 161. The medium flow channels 161 extend from the upper ends of the fins 17 to the lower ends of the fins 17, that is, the medium flow channels 161 surrounded by the fins 17 are equal in height to the medium flow channels 161 formed by the medium tubes 16. Here, the fins 17 are formed in a fork shape or a pincer shape, so that the heat exchange area can be increased and the heat exchange efficiency can be improved.

As shown in fig. 8, the pincer-like fins 172 include four fins, which are located right above, right below, right left, and right of the center of the circular cross section. However, the number and the arrangement position of the pincer-like fins 172 may be changed.

As described above, the nipper-shaped fins 172 may form the medium flow path 161 for passing the medium therethrough, and the nipper-shaped fins 172 may form the medium flow path 161 for inserting the support rod so that the heat exchanging apparatus can be supported on the ground or other devices, for example, in fig. 8, the medium flow path 161 located right to the left and right is used for flowing the medium, and the two medium flow paths 161 located right above and below are inserted into the support rod for supporting. Thus, the media flow channel 161 serves two purposes, for insertion of a support rod when not in use for flow of media.

With continued reference to fig. 8, the inner wall of the medium pipe 16 is inwardly protruded to form a plurality of protrusions 162, and the plurality of protrusions 162 are circumferentially distributed along the inner wall of the medium pipe 16. Therefore, the heat exchange area of the medium pipe 16 can be increased, and the heat exchange efficiency is improved.

Further, as shown in fig. 9, fig. 9 is a schematic cross-sectional view of a heat exchange device provided with a shell in another embodiment, and the heat exchange structure 1b further includes a shell 19 covering the medium tubes 16 and the fins 17. The outer shell 19 can be formed by extrusion with the medium pipe 16 and the fin 17 integrally or the medium pipe 16 and the fin 17, and the outer shell 19 is formed independently from the medium pipe 16 and the fin 17.

The outer shell 19, the medium pipe 16 and the fins 17 are made of aluminum alloy. The aluminum alloy material has good heat conductivity, so that the heat exchange efficiency of the heat exchange structure 1b can be improved.

Both the condensing means 20 and the evaporating means 10 may adopt the heat exchanging structure of any of the above embodiments or a structure in accordance with equivalent changes made to the heat exchanging structure. The refrigerant medium flowing through the medium flow passage 121 is a refrigerant, and may be, for example, a refrigerant such as tetrafluoroethane or freon.

When the evaporation device 10 adopts the heat exchange structure 1a (or 1b), the refrigerant after refrigeration is introduced into the medium circulation channel 121, the air to be cooled is introduced into the housing 11, and exchanges heat with the refrigerant in the medium circulation channel 121, the refrigerant absorbs heat, the air temperature is reduced, and the purpose of cooling the air is achieved.

The evaporation device 10 and the condensation device 20 both adopt the heat exchange structure, so that the evaporation device 10 and the condensation device 20 can be designed to be smaller, and the size of the air conditioning equipment is greatly reduced.

In the above embodiment, the evaporation apparatus 10 and the condensation apparatus 20 both adopt the above heat exchange structure to realize heat exchange, but the invention is not limited thereto, and one of the evaporation apparatus 10 and the condensation apparatus 20 may adopt the above heat exchange structure.

The restriction 50 may be an expansion valve or a capillary tube.

The fan 61 at the end of the condensing unit 20 may be a blower. The blower draws air from the end of the condensing unit 20 into the atmosphere and sends the air into the condensing unit 20 for heat exchange, and the air after heat absorption is sent to the exhaust port 103 through the ventilation pipe 21 at the bottom of the condensing unit 20 and is exhausted to the outside through the exhaust pipe at the exhaust port 103.
