The utility model provides a heat exchanger.
In an embodiment of the present invention, as shown in fig. 1 to 6, the heat exchanger 200 includes fins 210 and refrigerant tubes 220. The number of the fins 210 is a plurality of fins, and the plurality of fins 210 are arranged at intervals along the first direction. The refrigerant pipes 220 are disposed on the plurality of fins 210, so that when the refrigerant is transferred through the refrigerant pipes 220, the refrigerant can exchange heat with the external environment through the refrigerant pipes 210 and the fins 210.
In the embodiment, the thickness of the fins 210 is 0.085-0.105mm, and the distance between two adjacent fins 210 is 1.1-1.5 mm. Specifically, in the present embodiment, the fins 210 may have thicknesses of 0.085mm, 0.090mm, 0.095mm, 0.100mm, and 0.105 mm. The spacing between adjacent fins 210 may be 1.1mm, 1.2mm, 1.3mm, 1.4mm, and 1.5 mm.
In the present embodiment, the diameter of the cooling medium pipe 220 is 4 mm. The pipe diameter of the refrigerant pipe 220 being 4mm means that the pipe diameter of the refrigerant pipe 220 can fluctuate within a tolerance range on the basis of 4 mm. For example, when the tolerance is 0.1mm, the pipe diameter of the refrigerant pipe 220 is 4mm, which means that the pipe diameter of the refrigerant pipe 220 is 3.9-4.1 mm; when the tolerance is 0.2mm, the pipe diameter of the refrigerant pipe 220 is 4mm, which means that the pipe diameter of the refrigerant pipe 220 is 3.8-4.2 mm. In this embodiment, the diameter of the refrigerant pipe 220 refers to the outer diameter of the refrigerant pipe 220, and when the refrigerant pipe 220 is a circular pipe, the diameter of the refrigerant pipe 220 is 4mm, that is, the diameter of the refrigerant pipe 220 is 4mm, and when the refrigerant pipe 220 is irregular, the diameter of the refrigerant pipe 220 is 4mm, that is, the equivalent diameter of the refrigerant pipe 220 is 4 mm.
The thickness of the fins 210 is 0.085-0.105mm, that is, the thickness of the fins 210 is relatively thick, the distance between two adjacent fins 210 is 1.1-1.5mm, that is, the distance between two adjacent fins 210 is small, the thickness of the fins 210 is 0.085-0.105mm, and the distance between two adjacent fins 210 is 1.1-1.5mm, so that the strength of the fins 210 can be increased, and the stability of the fins 210 for supporting the refrigerant pipe 220 is improved, so that when the heat exchanger 200 adopts an R32 refrigerant, the pipe diameter of the refrigerant pipe 220 is 4mm, and the fins 210 can bear relatively high working pressure of the R32 refrigerant. Therefore, the heat exchanger 200 having the above-described structure can use the R32 refrigerant. In the heat exchanger field, when the number of the refrigerant pipes 220 is not changed, the larger the pipe diameter of the refrigerant pipe 220 is, the larger the material consumption of the refrigerant pipe 220 is, and the higher the manufacturing cost of the refrigerant pipe 220 is. In the heat exchanger 200, the diameter of the refrigerant pipe 220 is 4mm, that is, the diameter of the refrigerant pipe 220 is small, which can reduce the material consumption of the refrigerant pipe 220, and further reduce the manufacturing cost of the refrigerant pipe 220.
In the present embodiment, the arrangement direction (first direction) of the plurality of fins 210, the length direction (second direction) of the fins 210, and the width direction (third direction) of the fins 210 are perpendicular to each other. In the present embodiment, the width of the fins 210 is 9mm to 12 mm. Wherein, the width of the fin 210 is 9mm-12mm, that is, the width of the fin 210 in the third direction is 9-12 mm. Specifically, in the present embodiment, the width of the fin 210 may be 9mm, 10mm, 11mm, and 12 mm.
The width of the fins 210 is too large, the fins 210 are easily deformed after being subjected to a relatively high working pressure of the R32 refrigerant for a long time, and the width of the fins 210 is too small, so that the difficulty in installation is increased when the same number of refrigerant tubes 220 are installed. Moreover, for a multifold heat exchanger (including a plurality of heat exchange units, and the side edges of two adjacent heat exchange units in the width direction are connected), for example, a V-shaped heat exchanger, the width of the fin 210 is too large, which is not favorable for obtaining a miniaturized heat exchanger. In view of the above, in the present embodiment, the width of the fin 210 is set to 9mm to 12 mm.
In the embodiment, the wall thickness of the refrigerant pipe 220 is 0.1-0.12mm, that is, the wall thickness of the refrigerant pipe 220 is relatively small. Thus, the refrigerant pipe 220 can not only bear the relatively high working pressure of the R32 refrigerant for a long time, but also the refrigerant pipe 220 has relatively low material consumption, so that the manufacturing cost of the refrigerant pipe 220 can be further reduced. Specifically, in the present embodiment, the wall thickness of the refrigerant pipe 220 may be 0.10mm, 0.105mm, 0.11mm, 0.115mm, and 0.12 mm. Specifically, in the present embodiment, the cooling medium pipe 220 is a copper pipe.
In the present embodiment, as shown in fig. 7 and 8, the refrigerant pipe 220 includes a U-shaped pipe. In the present embodiment, the U-shaped pipe is plural. The hairpin tube includes a straight tube portion 222 and an elbow portion 224. The number of the straight tube portions 222 is two, and the two straight tube portions 222 are respectively inserted into the plurality of fins 210. The bent pipe portion 224 connects both ends of the two straight pipe portions 222 on the same side. It should be noted that the U-shaped refrigerant pipe 220 is a refrigerant pipe commonly used in the field of heat exchangers. It is understood that in other embodiments, the refrigerant tube 220 may have a linear shape, an S-shape, etc.
In this embodiment, the radius of the bent pipe portion 224 is 6.5-7.5mm, that is, the radius of the bent pipe portion 224 is relatively small, so that more U-shaped refrigerant pipes 220 can be disposed in the same space, the flowing distance of the refrigerant in the refrigerant pipes 220 is increased, and the heat exchange area of the refrigerant is increased. Specifically, in the present embodiment, the radius of the bent pipe portion 224 may be 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, 7.0mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, and 7.5 mm.
In the present embodiment, the inner wall of the refrigerant pipe 220 is provided with an internal thread. The inner wall of the refrigerant pipe 220 is provided with internal threads, so that the contact area between the refrigerant and the inner wall of the refrigerant pipe 220 can be increased, and sufficient heat exchange is realized.
In the present embodiment, the outer wall of the cooling medium pipe 220 is provided with an external thread. The outer wall of the refrigerant pipe 220 is provided with external threads, so that the contact area between the fins 210 and the refrigerant pipe 220 can be increased, and sufficient heat exchange is realized.
In this embodiment, the heat exchanger 200 is a multifold heat exchanger, and the heat exchanger 200 includes a plurality of (two or more) heat exchange units 202 connected in sequence, and two adjacent heat exchange units 202 are arranged at an included angle. Specifically, in the present embodiment, the side edges of two adjacent heat exchange units 202 in the width direction are connected. It is understood that in other embodiments, the heat exchanger 200 may have an arc shape or a flat plate shape, and in this case, the heat exchanger 200 may be considered to include one heat exchange unit 202.
In practical applications, when the multi-fold heat exchanger 200 is used in cooperation with the air duct assembly 14, due to the structural limitation of the air duct assembly 14, the wind speeds of the wind field formed by the air duct assembly 14 acting on the surfaces of the different heat exchange units 202 of the multi-fold heat exchanger 200 are different, which is not favorable for realizing the maximization of the heat exchange performance.
The following description will be made in detail by taking a V-type heat exchanger including two heat exchange units 202 having substantially the same windage as an example. As shown in fig. 9, fig. 9 is a CFD (Computational Fluid Dynamics) wind field diagram of the V-shaped heat exchanger, and it is apparent from fig. 9 that the lower heat exchange unit 202 (first heat exchange unit 202a) has a large amount of air flowing through it per unit time, the upper heat exchange unit 202 (second heat exchange unit 202b) has a small amount of air flowing through it per unit time, and the heat exchange capacity of the lower heat exchange unit 202 is higher than that of the upper heat exchange unit 202.
In order to solve the above problem, in the present embodiment, the windage resistances of at least two heat exchange units 202 of the heat exchanger 200 are different. Therefore, the heat exchange unit 202 with large wind resistance is arranged corresponding to the direction with large wind speed of the wind field formed by the air duct assembly 14, and the heat exchange unit 202 with small wind resistance is arranged corresponding to the direction with small wind speed of the wind field formed by the air duct assembly 14, so that the heat exchange performance is maximized. Specifically, the heat exchange unit 202 with a large wind speed (flow velocity) per unit area has a relatively large wind resistance, so that the air volume can be fully utilized for heat exchange; the heat exchange unit 202 with small wind speed (flow velocity) per unit area has relatively small wind resistance, so that more wind flows through the heat exchange unit, heat exchange is increased, and heat exchange performance is maximized.
In this embodiment, as shown in fig. 7 and 8, the density of the refrigerant pipe 220 of one heat exchange unit 202 is greater than that of the refrigerant pipe 220 of another heat exchange unit 202, so that the wind resistances of the two heat exchange units 202 are different. Taking the embodiment shown in fig. 7 and 8 as an example, the areas of the first heat exchange unit 202a and the second heat exchange unit 202b are substantially the same, and the number of the refrigerant pipes 220 of the first heat exchange unit 202a is greater than the number of the refrigerant pipes 220 of the second heat exchange unit 202b, so that the density of the refrigerant pipes 220 of the first heat exchange unit 202a is greater than the density of the refrigerant pipes 220 of the second heat exchange unit 202b, and further the wind resistance of the first heat exchange unit 202a is greater than the wind resistance of the second heat exchange unit 202 b.
There are many ways to make the windage of the two heat exchange units 202 different, and the above-mentioned ways are not limited. In some embodiments, the spacing between adjacent fins 210 of one heat exchange unit 202 is less than the spacing between adjacent fins 210 of another heat exchange unit 202, which may also cause the windage of the two heat exchange units 202 to be different. In some embodiments, the fins 210 of one heat exchange unit 202 have a first plate type, the fins 210 of another heat exchange unit 202 have a second plate type, and the wind resistance of the first plate type fins 210 is greater than that of the second plate type fins 210, so that the wind resistances of the two heat exchange units 202 are different. Specifically, in the present embodiment, the fins 210 of one heat exchange unit 202 are windowed die cut fins (windowed fins), and the fins 210 of another heat exchange unit 202 are bridge die cut fins (bridge fins). The windowing punching fin has a large windward area and relatively large wind resistance, while the bridge punching fin has a small windward area and relatively small wind resistance.
In the present embodiment, the heat exchanger 200 is a V-shaped heat exchanger. The heat exchanger 200 includes two heat exchange units 202. As such, the heat exchanger 200 is well suited for use in a ducted indoor unit 10. It is understood that in other embodiments, heat exchanger 200 may include three or more heat exchange units 202.
In this embodiment, the included angle formed by the two heat exchange units 202 is greater than 50 °. Therefore, the wind field can flow conveniently, and the sufficient heat exchange is realized. Specifically, in this embodiment, the included angle formed by the two heat exchange units 202 may be 60 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, and 170 °.
