The utility model provides a cabinet air conditioner, this cabinet air conditioner mainly used air conditioner to adjust the temperature of air.
Referring to fig. 1 and 2, the cabinet air conditioner includes a housing 10, the housing 10 having an air outlet 101 and an air inlet (not shown), and a wind wheel 20 and a heat exchanger 30 disposed in the housing 10, the heat exchanger 30 corresponding to the air inlet and/or the air outlet 101 of the housing 10. When the air conditioner works, the wind wheel 20 rotates, so that indoor air enters the shell 10 from the air inlet of the shell 10, exchanges heat with the heat exchanger 30 in the shell 10, and is blown out from the air outlet 101 of the shell 10, and the purpose of adjusting the indoor air temperature is achieved. The heat exchanger 30 may be opposite to one of the air inlet and the air outlet 101, or the heat exchanger 30 may be opposite to both the air inlet and the air outlet 101. Of course, when the heat exchanger 30 corresponds to the air inlet, the heat exchanger 30 has less influence on the wind speed at the air outlet 101.
Wherein, the wind wheel 20 may be a centrifugal wind wheel, an axial flow wind wheel, or a cross flow wind wheel. The cross flow wind wheel is taken as a preferred embodiment in consideration of noise.
Table 1 shows the comparison of the blowing distance and power of the cross-flow wind wheel and the centrifugal wind wheel under the condition of the same air volume
As can be seen from table 1, under the condition of the same air volume, the air supply distance of the centrifugal wind wheel is far longer than that of the cross-flow wind wheel, and the power of the centrifugal wind wheel is lower than that of the cross-flow wind wheel, and in summary, on the basis of adopting the single-row tube heat exchanger 30, the energy efficiency of the air conditioner adopting the centrifugal wind wheel is higher than that of the cross-flow wind wheel.
For the axial flow wind wheel, under the condition of the same power, the generated negative pressure is larger, so when the air conditioner operates, the flow speed of air passing through the single-row pipe heat exchanger 30 is faster, and the refrigeration efficiency of the centrifugal wind wheel is higher than that of the cross flow wind wheel in unit time.
The housing 10 may be cylindrical, elliptical, or square.
In this embodiment, the heat exchanger 30 is a single-tube heat exchanger 30, as shown in fig. 2 to 4, the single-tube heat exchanger 30 may specifically include a plurality of fins 31 arranged in parallel, and a refrigerant tube 32 penetrating through the plurality of fins 31, wherein the plurality of refrigerant tubes 32 are arranged at intervals along a length direction of each fin 31, and are arranged in a single row in an airflow flowing direction.
The connection manner between the refrigerant pipes 32 may be various, for example: the plurality of refrigerant pipes 32 may be sequentially connected in series, or some of the refrigerant pipes 32 may be connected in parallel and then sequentially connected in series with the other refrigerant pipes 32, which is not limited in this embodiment.
The refrigerant pipes 32 may be connected to each other by a connection pipe, which may be a straight pipe or a bent pipe.
It can be understood that the heat exchanger in the air conditioner cabinet is the single-row tube heat exchanger 30, and the fins 31 are in a single-row structure, so that the dislocation problem of the fins of the double-row tube heat exchanger or the multi-row tube heat exchanger caused by manufacturing errors can be avoided, and the resilience of the bent fins is reduced. In addition, the processing mode is very simple, the processing precision is easy to ensure, and the production efficiency can be improved. In addition, the single-row tube heat exchanger 30 has low cost and high heat exchange efficiency, so that the cabinet air conditioner has high cost performance.
As shown in fig. 3a to 3g and fig. 4, the single-row tube heat exchanger 30 has an air inlet side and an air outlet side, and the fin 31 includes a first heat exchanging portion 311 and a second heat exchanging portion 312, wherein the first heat exchanging portion 311 and the second heat exchanging portion 312 are arranged along the direction from the air inlet side to the air outlet side of the single-row tube heat exchanger 30, and the center line of the refrigerant tube 32 is located between the first heat exchanging portion 311 and the second heat exchanging portion 312.
In the present embodiment, specific arrangement of the first heat exchanging portion and the second heat exchanging portion is as follows:
referring to fig. 3a and 3b, the first heat exchanging portion 311 is disposed in a flat sheet shape, and at least a portion of the second heat exchanging portion 312 is disposed with a first wind blocking portion 313, where the first wind blocking portion 313 is in a louver structure and/or a bridge structure and/or a corrugated structure.
Here, the farther the fins 31 are from the refrigerant tubes 32, the greater the difference between the temperature of the fins and the temperature of the refrigerant tubes 32 is due to the heat conduction effect, and therefore, when the air conditioner performs heating, the temperature of the first heat exchanging portion 311 gradually increases along the direction from the air inlet side to the air outlet side of the single tube heat exchanger 30, and the temperature of the second heat exchanging portion 312 gradually decreases along the direction from the air inlet side to the air outlet side of the single tube heat exchanger 30. When the air flow with a low temperature passes through the first heat exchanging part 311, the temperature of the air flow gradually increases, and the temperature of the corresponding position of the first heat exchanging part 311 also gradually increases, so that a large temperature difference can be maintained between the first heat exchanging part 311 and the air flow, and a high heat exchanging efficiency can be achieved between the air flow and the first heat exchanging part 311. And when the air flow passes through the second heat exchanging part 312, the temperature of the air flow gradually rises, and the temperature of the position of the second heat exchanging part 312 corresponding to the air flow gradually falls, thereby causing the temperature difference between the air flows of the second heat exchanging part 312 to be gradually reduced, and causing the heat exchange efficiency between the air flow and the second heat exchanging part 312 to be low. When the air conditioner performs cooling, the effect is basically the same as that during heating. Therefore, the first heat exchanging portion 311 is kept as a flat plate, and the second heat exchanging portion 312 is provided with the first wind blocking portion 313, so that the heat exchanging amount of the air flow passing through the first heat exchanging portion 311 is not too large, and the heat exchanging amount of the air flow passing through the second heat exchanging portion 312 is not too small, thereby the heat exchanging of the air flow is more uniform as a whole.
In order to improve the heat exchange efficiency of the single-row tube heat exchanger as a whole, the specific arrangement conditions of the first heat exchange part and the second heat exchange part can also be as follows:
referring to fig. 3c to 3g, a second wind blocking portion 314 is disposed on at least a portion of the first heat exchanging portion 311, where the second wind blocking portion 314 is a plurality of louver structures 313a and/or a bridge structure and/or a corrugated structure; at least a part of the second heat exchanging part 312 is provided with a first wind blocking part 313, and the first wind blocking part 313 is a plurality of louver structures and/or bridge plate structures.
The plurality of louver structures 313a and/or the bridge structure may reduce the speed of the air flowing through the first heat exchanging part 311 and the second heat exchanging part 312, so as to increase the heat exchanging time between the air and the first heat exchanging part 311 and the second heat exchanging part 312, and to allow the air to exchange heat with the two heat exchanging parts more sufficiently, thereby increasing the heat exchanging efficiency of the heat exchanger 30.
Further, a plurality of louver structures 313a and/or bridge plate structures are arranged along the direction from the air inlet side to the air outlet side of the single-row tube heat exchanger 30, so as to further improve the wind shielding effect and enable the air flow to exchange heat with the fins more fully. Here, all or part of the louver structures 313a and/or the bridge structures of the first windshield portion 313 may be arranged in a direction from the air inlet side to the air outlet side of the single-row tube heat exchanger 30, and all or part of the louver structures 313a and/or the bridge structures of the second windshield portion 314 may be arranged in a direction from the air inlet side to the air outlet side of the single-row tube heat exchanger 30.
In addition, the window of the louver structure 313a may be directed toward the intake side of the single-tube heat exchanger 30 in the louver structure 313a, so as to further improve the wind shielding effect of the louver structure 313 a. Of course, the window of the louver structure 313a may face other directions, and the embodiment is not limited thereto.
The corrugated structure may be arranged in the width direction of the fin, extending in the length direction of the fin. The corrugated structure may extend in the width direction of the fin and be arranged in the length direction of the fin. Of course, the extending form of the corrugated structure may also be an intermittent extending form, that is, a plurality of strip-shaped protrusions are arranged at intervals in the length direction and/or the width direction of the fin.
In addition, the corrugated structure can also be a curved surface bulge, a block-shaped bulge or a triangular bulge formed on the surface of the fin, and the corrugated structure in the form can be arranged on the surface of the fin in an array.
The first windshield portion 313 provided in the second heat exchanging portion 312 may be in other forms, for example: at least a portion of the second heat exchanging portion 312 is provided with a corrugated structure, and such a corrugated arrangement of the second heat exchanging portion 312 may be a single-sided corrugation (one surface of the second heat exchanging portion is provided with a corrugated structure) or a double-sided corrugation (both sides of the second heat exchanging portion have a corrugated structure). Wherein the first wind shielding part 313 is a corrugated structure formed on the second heat exchanging part. When the first windshield portion 313 and/or the second windshield portion 314 have a corrugated structure, the corrugated structure extends in the longitudinal direction of the fin 31.
Of course, the first windshield portion 313 may be a combination of the louver structure, the bridge structure, or the corrugated structure.
As shown in fig. 5, when the first windshield portion 313 and/or the second windshield portion 314 is/are the louver structure 313a, the louver structure 313a has the opening angle α, in this embodiment, 18 ° < α < 28 °. it can be understood that if the opening angle α of the louver structure 313a is too small, the wind shielding effect of the louver structure 313a is poor, the heat exchange between the fins 31 and the airflow is insufficient, and the heat exchange efficiency of the single-row tube heat exchanger 30 is low, whereas if the opening angle α of the louver structure 313a is too large, the wind shielding effect of the louver structure 313a is too strong, which results in too low wind speed blowing from the wind outlet 101, and the blowing distance of the cabinet air conditioner is short, in this embodiment, the blowing effect of the cabinet air conditioner can be optimized by limiting the opening angle α of the louver structure 313a between 18 ° and 28 °, so that the single-row tube heat exchanger 30 has high heat exchange efficiency while the cabinet air conditioner has high blowing speed, wherein when the opening angle of the louver structure 313a 2 is α °, the optimal heat exchange efficiency of the single-row tube heat exchanger 30 is set for the second heat exchange efficiency, and the second heat exchanger 23, the heat exchange efficiency is set for the heat exchange efficiency test of the second heat exchanger according to the following experiment table, wherein the experiment results in the experiment that the heat exchange efficiency of the heat exchanger 30, the experiment show that:
A＝C0×ρ0x V × t × S × δ t; wherein, C0＝1.004KJ·Kg/℃，ρ0＝1.293Kg/m3，S＝0.1m2
From the above table, it can be seen that the value of a is between 0.7 and 0.74 when α is between 18 ° and 28 °, and the value of a is between 0.73 and 0.74 when α is between 22 ° and 24 °, the highest energy efficiency is achieved.
In this embodiment, the first wind blocking part 313 may be provided at one side of the second heat exchanging part 312, or the first wind blocking part 313 may be provided at both sides of the second heat exchanging part 312. Of course, when the first wind blocking portions 313 are simultaneously provided on both sides of the second heat exchanging portion 312, the space utilization rate of the fins 31 can be improved.
According to the heat conduction effect, the first windshield portion 313 and the refrigerant pipe 32 can be arranged along the direction from the air inlet side to the air outlet side of the single-row pipe heat exchanger 30, so as to further improve the heat exchange efficiency between the first heat exchange portion 311 and the air flow, and further increase the overall heat exchange amount between the single-row pipe heat exchange and the air flow. The louver structure 313a and/or the bridge structure on the first heat exchanging portion 311 may be opposite to the refrigerant pipes 32, or may be opposite to a gap between two adjacent refrigerant pipes 32, that is, at least a portion of the second air blocking portion 314 is disposed opposite to the refrigerant pipes 32 in a direction from the air inlet side to the air outlet side, which is not limited in this embodiment.
As shown in fig. 3a to 3g, the first heat exchanging portion 312 has a width H1 along the direction from the inlet side to the outlet side of the single-tube heat exchanger 30, and the second heat exchanging portion 311 has a width H2 along the direction from the inlet side to the outlet side of the single-tube heat exchanger 30. In this embodiment, the width H1 of the first heat exchanging portion 312 may be increased, or the width H2 of the second heat exchanging portion 311 may be decreased, so that H1 is equal to or greater than H2, thereby further improving the heat exchange efficiency of the single-row tube heat exchanger 30.
Further, the above H1 and H2 may be made to satisfy: H1/H2 is more than or equal to 1.0 and less than or equal to 2, so that the widths of the first heat exchanging part 312 and the second heat exchanging part 311 from the air inlet side to the air outlet side of the single-row tube heat exchanger 30 are more reasonable, the fins 31 and the air flow have larger heat exchange amount, the whole width of the fins 31 is reduced, and the cost of the fins 31 is reduced.
In a preferred embodiment, 1.2 ≦ H1/H2 ≦ 2, or 1.5 ≦ H1/H2 ≦ 2 may be used to make the ratio of H1 to H2 more reasonable and to make the heat exchange efficiency of the single-row tube heat exchanger 30 better.
In a preferred embodiment, with continued reference to fig. 3, the fins 31 of the single-row tube heat exchanger 30 are arranged along the circumferential direction of the casing 10, and the refrigerant tubes 32 are arranged along the length direction of the casing 10. The fin 31 of the single-tube heat exchanger 30 extends in the vertical direction, and the plurality of refrigerant tubes 32 are arranged in the longitudinal direction of the casing. So that the structure of the cabinet air conditioner is more compact, and the indoor space occupied by the cabinet air conditioner is reduced.
In the above embodiment, referring to fig. 6, 7 and 8, the fins 31 of the single-row tube heat exchanger 30 may be perpendicular to the horizontal direction, or may be disposed at an acute angle with respect to the horizontal plane, in the cabinet, the single-row tube heat exchanger 30 may be tilted forward, and the angle β between the tilted single-row tube heat exchanger 30 and the horizontal plane is greater than or equal to 42 ° and less than or equal to 90 °.
In addition to any of the above embodiments, the refrigerant inlet (not shown) of the heat exchanger 30 in the air-conditioner heating mode may be located at the lower portion of the heat exchanger 30, and the refrigerant outlet (not shown) of the heat exchanger 30 in the air-conditioner heating mode may be located at the middle portion or the upper portion of the heat exchanger 30. Therefore, when the air conditioner heats, the temperature of air after heat exchange with the lower part of the heat exchanger 30 is higher than the temperature of air after heat exchange with the middle part and the upper part of the heat exchanger 30, and when the air is blown out from the air outlet 101, the temperature of airflow blown out from the lower part of the air outlet 101 is higher than the temperature of airflow blown out from the middle part and the upper part of the air outlet 101, so that the heating effect of an indoor bottom layer is improved, and the cabinet air conditioner has the effect of being warm and cool when air is sent.
Or, when the air conditioner performs cooling, the temperature of the air after exchanging heat with the upper part of the heat exchanger 30 is higher than the temperature of the air after exchanging heat with the middle part and the lower part of the heat exchanger 30, and when the air is blown out from the air outlet 101, the temperature of the air flow blown out from the upper part of the air outlet 101 is lower than the temperature of the air flow blown out from the middle part and the lower part of the air outlet 101, so that the colder air flow is conveyed to a farther distance to quickly and uniformly reduce the indoor temperature.
It can be understood that the plurality of refrigerant pipes 32 may form one refrigerant circuit or a plurality of refrigerant circuits, when the plurality of refrigerant pipes 32 form a plurality of refrigerant circuits, one or more refrigerant inlets corresponding to the plurality of refrigerant circuits in the heating mode of the air conditioner are located at the lower portion of the heat exchanger 30, and the refrigerant outlet is located at the middle portion or the upper portion of the heat exchanger 30.
In this embodiment, the plurality of fins 31 of the heat exchanger 30 may be arranged along the circumferential direction of the casing 10, and the plurality of refrigerant tubes 32 may be arranged along the longitudinal direction of the casing 10.
It can be understood that after the fins 31 and the refrigerant pipes 32 of the heat exchanger 30 are arranged in the above manner, the refrigerant in the heating mode enters from the refrigerant inlet at the lower part of the heat exchanger 30 and flows out from the refrigerant outlet at the middle part or the upper part of the heat exchanger 30, so that the temperature difference between the airflow at the lower part of the air outlet 101 and the airflow at the upper part can be increased, and the effect of sufficient warm and cool air when the cabinet air conditioner supplies air is further improved.
Further, the side surfaces of the fins 31 may extend in the radial direction of the casing 10, so that the distance between two adjacent fins 31 is reduced in the direction from the air inlet side to the air outlet side of the heat exchanger 30, thereby improving the heat exchange efficiency between the heat exchanger 30 and the air flow.
Of course, the plurality of fins 31 may be arranged along the longitudinal direction of the housing 10, or the plurality of fins 31 may be arranged along a direction inclined at a certain angle to the longitudinal direction of the housing 10, which will not be described herein again.
In this embodiment, the heat exchanger 30 further includes a left plate 41 and a right plate 42, the left plate 41 and the right plate 42 are respectively located at the left and right sides of the heat exchanger 30 and are used for fixing the refrigerant tubes 32 and the fins 31, and the heat exchanger 30 is fixedly connected to the housing 10 through the left plate 41 and the right plate 42.
In this embodiment, as shown in fig. 2, an electric auxiliary heating device 40 may be further disposed between the heat exchanger 30 and the fan assembly 20, and when the air conditioner heats, the electric auxiliary heating device 40 may generate heat, so as to improve a heating effect of the cabinet air conditioner.
It can be understood that, since the present invention provides an air conditioner including all the solutions of all the embodiments of the above-mentioned cabinet air conditioner, at least the same technical effects as the cabinet air conditioner are obtained, which is not necessarily explained here.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
