Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.
A heat exchanger 1 according to an embodiment of the present invention, as shown in fig. 1 and 2, includes: a plurality of spaced fin packs 1a, a first header 20, and a second header 30.
Specifically, the fin assembly 1a includes a refrigerant pipe 11 and fins 10 arranged on the refrigerant pipe 11, the refrigerant pipe 11 is used for allowing a refrigerant to pass through, and the refrigerant exchanges heat with the fins 10, so that an airflow passing through the fins 10 can exchange heat with the fins 10. One end of the refrigerant pipe 11 forms a passage inlet 11a, and the other end of the refrigerant pipe 11 forms a passage outlet 11 b. The fins 10 are spaced apart along the length direction of the first header 20, the first header 20 is communicated with the channel inlets 11a, the first header 20 has a refrigerant inlet 20a, and a refrigerant flows into the first header 20 through the refrigerant inlet 20a and flows into the refrigerant tubes 11 through the channel inlets 11 a. The plurality of fins 10 are spaced apart along the length direction of the second collecting pipe 30, the second collecting pipe 30 is communicated with the plurality of channel outlets 11b, the refrigerant flowing into the plurality of refrigerant pipes 11 is divided and flows into the second collecting pipe 30 through the channel outlets 11b, the second collecting pipe 30 has a refrigerant outlet 30a, and the refrigerant gathered to the second collecting pipe 30 flows out of the heat exchanger 1 through the refrigerant outlet 30 a.
According to the heat exchanger 1 provided by the embodiment of the invention, the plurality of refrigerant pipes 11 are communicated with the second collecting pipe 30 through the first collecting pipe 20, so that when airflow passes through the space between two adjacent fins 10, the air inlet resistance is small, the air supply amount is increased, and further the heat exchange amount of the heat exchanger 1 is increased. In addition, the refrigerant pipes 11 are connected in parallel, so that the temperature difference of the fins 10 is small, and the uniformity of heat exchange of the heat exchanger 1 is improved.
In some embodiments of the present invention, as shown in fig. 2, a plurality of fins 10 are arranged in parallel, so that when the airflow passes between two adjacent fins 10, the resistance of the fins 10 to the airflow can be further reduced, so that the airflow passing through the heat exchanger 1 is increased, and the heat exchange capacity of the heat exchanger 1 is further increased. Each fin 10 is perpendicular to the extending direction of the first header 20 and the extending direction of the second header 30. Therefore, the volume is certain, and the quantity of the fins 10 of the heat exchanger 1 is increased under the condition that the distance between the adjacent fins 10 is certain, so that the total heat exchange area of the heat exchanger 1 is larger, and the heat exchange quantity of the heat exchanger 1 is improved.
Further, the distance between the surfaces of the two adjacent fins 10 close to each other is D1, the minimum distance between the outer walls of the refrigerant tubes 11 connected with the two adjacent fins 10 is D2, and when the distance is more than or equal to 0.2 and less than or equal to D2/D1 and less than or equal to 0.95, the heat exchange area of the heat exchanger 1 is increased due to the increase of the thickness of the fins 10, but the distance between the fins 10 is reduced due to the increase of the thickness of the fins 10, the wind resistance is increased, the heat exchange efficiency of the heat exchanger 1 is better due to the increase of the diameter of the refrigerant tubes 11, the heat exchange efficiency is better due to the increase of the diameter of the refrigerant tubes 11, the distance between the surfaces of the two adjacent fins 10 close to each other is properly proportional to the minimum distance between the outer walls of the refrigerant tubes 11 connected with the two adjacent fins 10, the heat exchange efficiency of the heat exchanger 1 can be made better.
According to some embodiments of the invention, the fins 10 have a thickness of 0.01-2 mm. For example, the thickness of the fin 10 may be 0.01mm, 0.05mm, 0.5mm, 1.0mm, 1.5mm, 2mm, or the like. The increase in thickness of the fins 10 can increase the heat exchange area of the heat exchanger 1, but the increase in thickness of the fins 10 can reduce the distance between the fins 10, increase the wind resistance, and reduce the air supply volume, so that the heat exchange efficiency of the heat exchanger 1 can be better due to the appropriate thickness of the fins 10. The distance between the surfaces of two adjacent fins 10 close to each other is 2-10 mm. For example 2mm, 4mm, 5mm, 7mm, 9mm or 10mm etc. The larger the distance between two adjacent fins 10 is, the smaller the resistance to the air flow passing through between the fins 10 is, but under the condition that the volume of the heat exchanger 1 is fixed, the larger the distance between two adjacent fins 10 is, the smaller the number of the fins 10 is, so that the smaller the heat exchange area is, and therefore, the better the heat exchange effect of the heat exchanger 1 can be achieved by the moderate distance between two adjacent fins 10.
According to some embodiments of the present invention, as shown in fig. 2, the refrigerant tube 11 extends along the length direction of the fin 10, and the first header 20 and the second header 30 are respectively located at two ends of the fin 10 in the length direction. Therefore, when the airflow passes through the space between two adjacent fins 10, the air inlet resistance is small, the air supply amount is further increased, and the heat exchange amount of the heat exchanger 1 is further increased.
Further, as shown in fig. 1, the fin 10 includes a first fin 12 and a second fin 13 respectively located at two opposite sides of the refrigerant tube 11, a distance between an outer wall of the refrigerant tube 11 and an end of the first fin 12 far away from the refrigerant tube 11 is L1, and a distance between L1 and the first fin 12 is 2-25mm, such as 2mm, 5mm, 7mm, 10mm, 15mm, 20mm or 25 mm. The larger the L1 is, the larger the heat exchange area is, the larger the heat exchanger 1 is, but when the heat exchanger 1 is applied to the air conditioner 100, the larger the heat exchanger 1 is, the narrower the thickness of the air duct 5 behind the heat exchanger 1 is, which is not beneficial to cold air deposition, in a cavity of the air conditioner 100 with a certain volume, and therefore the distance between the outer wall of the suitable refrigerant pipe 11 and one end, far away from the refrigerant pipe 11, of the first fin 12 can enable the heat exchange effect of the heat exchanger 1 to be better. As shown in fig. 1, the distance between the outer wall of the refrigerant tube 11 and the end of the second fin 13 far from the refrigerant tube 11 is L2, and L2 is 2-25mm, such as 2mm, 5mm, 7mm, 10mm, 15mm, 20mm or 25 mm. The larger the L2 is, the larger the heat exchange area is, the larger the volume of the heat exchanger 1 is, but when the heat exchanger 1 is applied to the air conditioner 100, as shown in fig. 3, in a cavity of the air conditioner 100 with a certain volume, the larger the volume of the heat exchanger 1 is, the narrower the thickness of the air duct 5 behind the heat exchanger 1 is, which is not beneficial to cool air deposition, and therefore, the distance between the outer wall of the refrigerant pipe 11 and one end, far away from the refrigerant pipe 11, of the second fin 13 is suitable, so that the heat exchange effect of the heat exchanger 1 is better.
According to some embodiments of the present invention, as shown in fig. 1 and 3, the fin 10 includes a first section 14 and a second section 15, one end of the first section 14 is connected to one end of the second section 15, the first section 14 and the second section 15 form an included angle, the refrigerant pipe 11 includes a first refrigerant pipe 112 disposed on the first section 14 and a second refrigerant pipe 114 disposed on the second section 15, one end of the first refrigerant pipe 112 is connected to one end of the second refrigerant pipe 114, the other end of the first refrigerant pipe 112 is formed as a channel inlet 11a, and the other end of the second refrigerant pipe 114 is formed as a channel outlet 11 b. When the heat exchanger 1 is applied to the air conditioner 100, the airflow passes through the space between the first sections 14 adjacent to each other and the space between the second sections 15 adjacent to each other, so that the airflow can exchange heat with the heat exchanger 1 when entering air from multiple angles, the air inlet amount is further increased, and the heat exchange effect of the heat exchanger 1 is improved.
Further, as shown in fig. 1, the first segment 14 and the second segment 15 define an angle space, and an angle between an edge of the first segment 14 near the angle space and an edge of the second segment 15 near the angle space is α, α satisfies: alpha is more than or equal to 95 degrees and less than or equal to 165 degrees, such as 105 degrees, 110 degrees, 115 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees and the like. When the heat exchanger 1 is applied to the air conditioner 100, a water pan 4 for collecting condensed water may be disposed below the second section 15, so that condensed water condensed on the surface of the first section 14 may flow to the second section 15 along the edge inclined toward the space of the included angle α and flow into the water pan 4 along the second section 15.
Further, as shown in fig. 1, the first section 14 and the second section 15 define an included angle space, an angle between an edge of the first section 14 away from the included angle space and an edge of the second section 15 away from the included angle space is β, β satisfies 90 ° β ≦ 175 °, when the heat exchanger 1 is applied to the air conditioner 100, the space can be better utilized, the space utilization rate is higher, and the space volume required for installing the heat exchanger 1 is reduced.
Further, as shown in fig. 1 and 3, an included angle between the first refrigerant pipe 112 and the second refrigerant pipe 114 is θ, and θ satisfies 40 ° ≦ θ ≦ 165 °. For example 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °, 105 °, 110 °, 115 °, 130 °, 140 °, 150 °, 160 °, etc. When the heat exchanger 1 is applied to the air conditioner 100, the possibility that the heat exchanger 1 shortens the length of the air duct 5 behind the heat exchanger 1 can be reduced.
According to some embodiments of the present invention, the length of the outer contour of the cross section of the refrigerant pipe 11 is greater than the width, and the width direction of the outer contour of the cross section of the refrigerant pipe 11 is the same as the thickness direction of the fin 10. Therefore, on the premise that the distance between the fins 10 is constant, the shortest distance between the fins 10 is increased, so that the resistance of the airflow passing through the two adjacent fins 10 is reduced, and the heat exchange effect of the heat exchanger 1 is further improved.
As shown in fig. 3 and 4, an air conditioner 100 according to an embodiment of the present invention includes: a casing 2, the heat exchanger 1 and a fan 3. The shell 2 is provided with an air inlet 2a and an air outlet 2b, the heat exchanger 1 is arranged in the shell 2, the heat exchanger 1 is opposite to the air inlet 2a, the fan 3 is arranged in the shell 2 to drive airflow to flow from the air inlet 2a to the air outlet 2b through the heat exchanger 1, the airflow enters the air conditioner 100 through the air inlet 2a and exchanges heat with the heat exchanger 1, and then flows out of the air conditioner 100 through the air outlet 2b to enter the room through the driving of the fan 3, and therefore the room temperature can be adjusted.
It should be noted that, as shown in fig. 3 and 4, the air inlet 2a of the air conditioner 100 includes a first inlet 21a and a second inlet 22a, the first inlet 21a is located at the upper end of the air conditioner 100, and the second inlet 22a is located at the front end of the air conditioner 100.
According to the air conditioner 100 provided by the embodiment of the invention, because the air inlet resistance of the heat exchanger 1 is small, the air supply quantity is increased, and further the heat exchange quantity of the heat exchanger 1 is increased, so that the heat exchange efficiency of the air conditioner 100 is improved.
Further, the fan 3 is arranged below the heat exchanger 1, so that more air flows exchanging heat with the heat exchanger 1 can be driven to flow out of the air outlet 2b, and the room temperature adjusting effect is improved.
Further, as shown in fig. 3, the air conditioner 100 further includes a water pan 4, and the water pan 4 is disposed in the casing 2 and below the heat exchanger 1, so that condensed water flowing down from the surface of the heat exchanger 1 can be collected, and the possibility that the condensed water flows into other components and damages the other components is reduced.
Further, as shown in fig. 3, a distance L3 between the heat exchanger 1 and the inner wall of the casing 2 is 0.5 to 3mm, for example, 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, or the like.
