[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0035] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures" afterwards. Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present utility model.

[0037] The present utility model provides a heat recovery device and an air conditioner, which can solve the technical problems of complex pipeline components and low assembly efficiency of the air conditioner in the prior art.

[0038] Referring to Figures 1-7 As shown, a heat recovery device is applied to an air conditioner. The air conditioner includes an evaporator 901, a condenser 902, and a compressor 903, and includes:

[0039] A capillary tube 2, the inlet of the capillary tube 2 is communicated with the condenser 902; the outlet of the capillary tube 2 is communicated with the evaporator 901;

[0040] An intake pipe 3, the inlet of the intake pipe 3 is communicated with the evaporator 901, and the outlet of the intake pipe 3 is communicated with the suction port of the compressor 903;

[0041] A fin 4 is provided with a first hole and a second hole. The capillary tube 2 passes through the first hole, and the intake pipe 3 passes through the second hole.

[0042] By integrating the capillary tube 2, the intake pipe 3, the filter 5, and the fin 4 into a heat recovery device 1, the pipeline layout in the air conditioner is simplified, which is beneficial to improving production efficiency.

[0043] After the refrigerant flows out of the compressor 903, it flows through the condenser 902, the capillary tube 2, the evaporator 901, and the intake pipe 3 in sequence, and then flows back to the compressor 903. The temperature of the refrigerant in the capillary tube 2 is higher than that of the refrigerant in the intake pipe 3. The capillary tube 2 and the intake pipe 3 are thermally coupled, and the low-temperature refrigerant in the intake pipe 3 can preliminarily cool (pre-cool) the high-temperature refrigerant in the capillary tube 2, which is beneficial to recovering the cold energy condensed in the intake pipe 3, improving the refrigeration effect after the refrigerant flows out of the capillary tube 2, and thus improving the energy efficiency.

[0044] The capillary tube 2 and the intake pipe 3 are connected together by the fin 4. The fin 4 can not only be used for heat conduction and heat dissipation, but also play a role in supporting and fixing the capillary tube 2, avoiding the vibration of the capillary tube 2 caused by the flow of the high-pressure refrigerant in the capillary tube 2.

[0045] A liquid distribution pipe is further provided between the capillary tube 2 and the evaporator 901. The liquid distribution pipe is used to evenly flow the refrigerant into the evaporator 901. A gas collecting pipe is further provided between the intake pipe 3 and the evaporator. The gas collecting pipe is used to collect the refrigerant flowing out of the evaporator, and the collected refrigerant flows into the intake pipe 3.

[0046] On the one hand, the capillary tube 2 and the suction pipe 3 exchange heat with air through the fins 4, which improves the heat exchange efficiency between the capillary tube 2, the suction pipe 3 and the air. The capillary tube 2 releases heat to the air through the fins 4, and the suction pipe 3 releases cold to the air through the fins 4. The heat and cold conduct in the air, which improves the heat exchange efficiency between the capillary tube 2 and the air and the heat exchange efficiency between the suction pipe 3 and the air, is conducive to recovering the cold condensed in the suction pipe 3, and is conducive to reducing the temperature of the refrigerant in the capillary tube 2. On the other hand, as a heat transfer medium, the fin 4 directly connects the capillary tube 2 and the suction pipe 3, which speeds up the heat exchange efficiency between the capillary tube 2 and the suction pipe 3.

[0047] The connecting pipe can be a U-shaped pipe.

[0048] The regenerative device 1 is a separate module, and pipeline interfaces are provided at both ends of the capillary tube 2 and both ends of the suction pipe 3 for connecting with external pipelines, which further improves the production efficiency of the air conditioner. During specific installation, it can be welded to other pipelines by welding, with simple operation and improved production efficiency.

[0049] Preferably, the capillary tube 2 has an interference fit with the first hole, and the suction pipe 3 has an interference fit with the second hole;

[0050] Or,

[0051] The capillary tube 2 has a transition fit with the first hole, and the suction pipe 3 has a transition fit with the second hole.

[0052] Furthermore, the capillary tube 2 is detachably passed through the first hole, and the suction pipe 3 is detachably passed through the second hole; in this way, according to the need of the external refrigerant flow rate, the capillary tube 2 and the suction pipe 3 with corresponding inner diameters can be passed through the fin 4. Of course, when the inner diameter changes, the corresponding outer diameter will also change. At this time, the first hole and the second hole on the fin 4 are also processed according to the outer diameters of the capillary tube 2 and the suction pipe 3.

[0053] The interference fit between the capillary tube 2 and the first hole and the interference fit between the suction pipe 3 and the second hole are conducive to improving the connection stability between the two tubes and the holes, and are also conducive to the heat conduction between the tubes and the fin 4.

[0054] The transition fit between the capillary tube 2 and the first hole and the transition fit between the suction pipe 3 and the second hole are conducive to the tube passing through the hole, facilitating installation, and are conducive to reducing the frictional noise generated when the tube passes through the hole.

[0055] Preferably, as Figures 1-2As shown, the regenerative device 1 includes a first side plate 601 and a second side plate 602, and the first side plate 601 and the second side plate 602 are separately arranged along the length direction of the suction pipe 3; there are a plurality of fins 4, and the plurality of fins 4 are arranged between the first side plate 601 and the second side plate 602.

[0056] The first side plate 601 and the second side plate 602 sandwich the plurality of fins 4 in the middle. The first side plate 601 and the second side plate 602 are used to fix the regenerative device 1, improving the convenience of fixing the regenerative device 1.

[0057] Preferably, as Figures 1-2 shown, the first side plate 601 is an L-shaped plate. The first side plate 601 includes a first bottom plate 6012 and a first side plate 6011. Both the capillary tube 2 and the suction pipe 3 pass through the first side plate 6011, and the first bottom plate 6012 extends in a direction away from the second side plate 602;

[0058] and / or,

[0059] the second side plate 602 is an L-shaped plate. The second side plate 602 includes a second bottom plate 6022 and a second side plate 6021. Both the capillary tube 2 and the suction pipe 3 pass through the second side plate 6021, and the second bottom plate 6022 extends in a direction away from the first side plate 601.

[0060] By setting the first side plate 601 and the second side plate 602 as L-shaped plates, and the first bottom plate 6012 of the first side plate 601 extends away from the second side plate 602, and the second bottom plate 6022 of the second side plate 602 extends away from the first side plate 601, the regenerative device 1 can be fixed by using the first bottom plate 6012 and the second bottom plate 6022. Further, fixing holes are provided on the first bottom plate 6012 and the second bottom plate 6022, and are fixed by bolts passing through the fixing holes. Welding can also be performed. Threaded holes can be provided on the first bottom plate 6012 and the second bottom plate 6022, and the bolts pass through the structure for fixing the regenerative device 1 and cooperate with the threaded holes on the bottom plates for fixing. By changing the distance between the first side plate 601 and the second side plate 602 and the number of fins 4, the distance between the capillary tube 2 and the suction pipe 3 is changed, and then the specification size of the regenerative device 1 is changed, so that the regenerative device 1 can be installed in different spaces, improving the versatility of the regenerative device 1.

[0061] The change in the distance between the first hole and the second hole can change the distance between the capillary tube 2 and the suction pipe 3; when the number of the same fins 4 is the same, the larger the distance between adjacent fins 4, the larger the distance between the first side plate 601 and the second side plate 602; when the distance between adjacent fins 4 is constant, the more the fins 4, the larger the distance between the first side plate 601 and the second side plate 602. The distance between the first hole and the second hole, the number of fins 4, and the distance between the first side plate 601 and the second side plate 602 are all determined by actual needs.

[0062] Preferably, as Figures 1-2 shown, a filter 5 is provided on the pipe between the capillary tube 2 and the condenser.

[0063] The setting of the filter 5 prevents impurities in the refrigerant from entering the capillary tube 2.

[0064] Preferably, as Figures 1-2 shown, a flow divider 7 is provided on the suction pipe 3; the flow divider 7 includes three communicating ports, two of which are communicated with the suction pipe 3, and the other port is a fluorine injection port 701 for charging fluorine.

[0065] The refrigerant enters the flow divider 7 from one port of the flow divider 7, flows out of the flow divider 7 from another port, and enters the compressor 903 after flowing out of the flow divider 7; one port of the flow divider 7 is used for charging fluorine. Integrating the flow divider 7 into the regenerative device 1 further improves the integration degree of the regenerative device 1 and further improves the convenience of installing the regenerative device 1.

[0066] The present utility model also provides an air conditioner, as Figures 3-5 shown, the air conditioner includes the regenerative device 1 described above.

[0067] Preferably, as Figures 3-5 shown, the air conditioner is a cabinet air conditioner, the cabinet air conditioner includes a housing 8, the regenerative device 1 is arranged in the housing 8, and a fan is arranged in the housing 8. When the fan works, air can first flow through the suction pipe 3 and then through the capillary tube 2.

[0068] The cabinet air conditioner can be a 5G cabinet air conditioner.

[0069] The temperature of the refrigerant in the suction pipe 3 is relatively low, and the suction pipe 3 releases cold to the air. The temperature of the refrigerant in the capillary tube 2 is relatively high, and the capillary tube 2 releases heat to the air; air first flows through the suction pipe 3, the temperature decreases after heat exchange with the suction pipe 3, and the air with decreased temperature then flows through the capillary tube 2. The relatively low-temperature air exchanges heat with the capillary tube 2 to cool the refrigerant in the capillary tube 2; in this way, the heat exchange efficiency between the suction pipe 3 and the capillary tube 2 is improved, the effect of pre-cooling the refrigerant is achieved, the energy efficiency is improved, and energy is saved.

[0070] A base 801 is provided at the bottom of the housing 8. The base 801 not only plays a supporting role but also reduces the impact of the vibration of the air conditioner on the floor.

[0071] Preferably, as Figures 3-5 shown, the setting of the regenerative device 1 enables the air flow generated when the fan operates to flow along the plate surface of the fin 4.

[0072] As a heat conduction medium, the fin 4 can not only directly transfer heat between the suction pipe 3 and the capillary tube 2, but also increase the heat exchange efficiency between the air and the capillary tube 2 and between the air and the suction pipe 3; when the air flows along the plate surface of the fin 4, the air serves as a heat conduction medium, and the air flow also speeds up the heat conduction speed between the fin 4 and the air. Further, it speeds up the speed of the suction pipe 3 releasing cold and the speed of the capillary tube 2 releasing heat; thus achieving the effect of pre-cooling the refrigerant in the capillary tube 2.

[0073] The size of the fin 4 can be determined according to the space where the regenerative device 1 is to be installed, or it can be set standardly. When multiple fins 4 are taken as a whole, the size of the space occupied by the fins 4 can be: 100mm×84mm×24mm.

[0074] Preferably, as Figures 3-5 shown, the cabinet air conditioner includes an evaporator 901 and a condenser 902. The housing 8 includes a front side plate 803 and a rear side plate 804 arranged oppositely. The evaporator 901 is located at the lower part of the housing 8 and adjacent to the front side plate 803, and the condenser 902 is located at the upper part of the housing 8 and adjacent to the rear side plate 804; a partition 802 is provided inside the housing 8. The partition 802 extends from top to bottom to divide the interior of the housing 8 into a front chamber 805 and a rear chamber 806. The evaporator 901 is located in the front chamber 805, the condenser 902 is located in the rear chamber 806, and the regenerative device 1 is located in the rear chamber 806 and fixed on the partition 802.

[0075] The cabinet air conditioner includes an evaporator 901 and a condenser 902. The housing 8 includes a front side plate 803 and a rear side plate 804 which are oppositely arranged. The evaporator 901 is located at the lower part of the housing 8 and adjacent to the front side plate 803, and the condenser 902 is located at the upper part of the housing 8 and adjacent to the rear side plate 804; the distance between the evaporator 901 and the condenser 902 is set as far as possible to avoid excessive heat exchange between the evaporator 901 and the condenser 902 and reduce the refrigeration efficiency. A partition plate 802 is arranged in the housing 8. The partition plate 802 extends from top to bottom to divide the interior of the housing 8 into a front chamber 805 and a rear chamber 806. The evaporator 901 is located in the front chamber 805, and the condenser 902 is located in the rear chamber 806; by arranging the partition plate 802, the air flow between the evaporator 901 and the condenser 902 is further reduced; the heat recovery device 1 is located in the rear chamber 806 and fixed on the partition plate 802, that is, the heat recovery device 1 and the condenser 902 are arranged in the same chamber. The evaporator 901 is closer to the user activity area than the condenser 902. The pipelines in the air conditioner are arranged in the chamber where the condenser 902 is located as much as possible, including the compressor 903 mentioned later. In this way, the heat, vibration and noise generated by the pipelines can be prevented from having an adverse impact on the room; the heat recovery device 1 and the condenser 902 are arranged in the same chamber, which is convenient for the heat recovery device 1 to be connected to other pipelines and further improves the convenience of pipeline layout in the air conditioner.

[0076] Two mounting holes can be provided on each of the first bottom plate 6012 and the second bottom plate 6022, and the heat recovery device 1 is mounted on the partition plate 802 by self-tapping screws.

[0077] The fan can be set separately or the external fan 808 for the condenser 902 can be used. When the external fan 808 for the condenser 902 is used, the heat recovery device 1 is arranged above the external fan 808 of the condenser 902, and the suction pipe 3 is arranged below the capillary tube 2. When the external fan 808 works, it blows air out of the housing 8, and the blown air makes the air flow from bottom to top, first flowing through the suction pipe 3 and then through the capillary tube 2, thereby accelerating the flow of the relatively cold air after heat exchange with the suction pipe 3 through the capillary tube 2 to pre-cool the relatively hot refrigerant in the capillary tube 2. The internal fan 809 is for the evaporator 901, and the internal fan 809 works to make the external air flow through the evaporator 901 and then return to the outside (indoor space).

[0078] Preferably, as Figures 3-5As shown, from top to bottom, the partition plate 802 inclines from the rear side plate 804 towards the front side plate 803. The cabinet air conditioner further includes a compressor 903, and the compressor 903 is located in the rear chamber 806 below the condenser 902; a water receiving tray 807 is arranged below the evaporator 901, and the lower end of the partition plate 802 is connected to the water receiving tray 807.

[0079] The partition plate 802 inclines from the rear side plate 804 towards the front side plate 803, which makes the lower space of the space formed between the partition plate 802 and the rear side plate 804 larger, facilitating the installation of the compressor 903 in the rear chamber 806 below the condenser 902. A water receiving tray 807 is arranged below the evaporator 901, and the lower end of the partition plate 802 is connected to the water receiving tray 807. When the evaporator 901 cools the air in the front chamber 805, condensed water is generated on the inner wall surface in the front chamber 805. Among them, the condensed water on the partition plate 802 can flow along the partition plate 802 into the water receiving tray 807, improving the convenience of condensed water collection.

[0080] Furthermore, the height of the water receiving tray 807 can be higher than the lowest position of the compressor 903. A drain pipe is arranged at the bottom of the water receiving tray 807, and the condensed water flows along the drain pipe to the outer wall of the compressor 903 to cool the compressor 903, improving the working efficiency of the compressor 903 and avoiding the decrease in efficiency caused by the overheating of the compressor 903.

[0081] It is easy for those skilled in the art to understand that, on the premise of no conflict, the advantageous technical features of the above various methods can be freely combined and superimposed.

[0082] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and variations can still be made, and these improvements and variations should also be regarded as the protection scope of the present invention.
