Description

Technical Field

[0001] The utility model relates to the technical field of coil unit packaging, in particular to a packaging component and a coil unit packaging. Background Art

[0002] At present, the coil unit includes a heat exchange component, and some of them also have an outer shell. The outer shell can be put on the outer circumference of the heat exchange component, and the opposite ends of the outer shell have openings for the heat exchange component to be installed. In the related art, when transporting the coil unit, a foam pad is usually used to package the coil unit. In order to prevent the heat exchange component from shaking, part of the structure of the foam pad is configured to abut the end face of the heat exchange component. However, for coil units of different heights, the shape of the end face of the heat exchange component will change, making it difficult for the foam pad to adapt to different end faces. The foam pad is easy to shake, and the limiting effect of the heat exchange component is not good. Therefore, the current packaging structure is difficult to be compatible with the packaging of coil units of different heights, and it is necessary to design corresponding packaging structures for coil units of different heights, resulting in high costs. Utility Model Content

[0003] The main purpose of the utility model is to provide a packaging component and a coil unit packaging, aiming to solve the technical problem of how to compatibly package coil units of different heights.

[0004] To achieve the above-mentioned purpose, the utility model proposes a packaging component for accommodating a coil unit, the coil unit including a heat exchange component, the packaging component including: a first protective pad having a first direction and a second direction perpendicular to each other, the first protective pad having a first side and a second side relatively arranged in the first direction, the first side forming an abutment structure for abutting the heat exchange component, the abutment structure including a first abutment surface and a second abutment surface arranged back to back to each other along the second direction, the distance between the first abutment surface and the second abutment surface gradually increasing from the first side to the second side, the abutment structure forming a first abutment portion at one end of the first abutment surface away from the second abutment surface, along the normal direction of the first abutment surface, the first abutment portion protrudes from the first abutment surface, the abutment structure forming a second abutment portion at one end of the second abutment surface away from the first abutment surface, along the normal direction of the second abutment surface, the second abutment portion protrudes from the second abutment surface.

[0005] In some embodiments, a third abutting surface is formed on one side of the first abutting portion abutting against the heat exchange component, the first abutting surface and the third abutting surface are configured as inclined surfaces, and an inclination angle of the third abutting surface relative to the first direction is greater than an inclination angle of the first abutting surface relative to the first direction;

[0006] and / or;

[0007] A fourth abutting surface is formed on one side of the second abutting portion abutting against the heat exchange component. The second abutting surface and the fourth abutting surface are configured as inclined surfaces. An inclination angle of the fourth abutting surface relative to the first direction is greater than an inclination angle of the second abutting surface relative to the first direction.

[0008] In some embodiments, a first protrusion is formed on the first side, and a contact structure is formed on the side of the first protrusion facing away from the second side. A first flange portion is also formed on the first side and arranged around the first protrusion. A first accommodating groove for accommodating the end of the coil unit is formed between the first flange portion and the first protrusion.

[0009] In some embodiments, a first groove and a second groove are provided on the second side, the position of the first groove corresponds to the position of the first accommodating groove, the position of the second groove corresponds to the position of the first protrusion, and in the first direction, the maximum depth of the second groove is greater than the maximum depth of the first groove.

[0010] In some embodiments, a side of the first protrusion for abutting against the heat exchange component is formed with an avoidance groove, and the avoidance groove is used to avoid the pipeline of the coil unit.

[0011] In some embodiments, the packaging assembly includes a second protection pad, the second protection pad has a third direction and a fourth direction perpendicular to each other, and the second protection pad has a third side and a fourth side oppositely arranged along the third direction.

[0012] In some embodiments, a second protrusion is formed on the third side, and the second protrusion has a peripheral wall arranged around an axis parallel to the third direction. When the packaging assembly accommodates the coil unit, the first protective pad and the second protective pad are respectively arranged at opposite ends of the coil unit, and the peripheral wall is configured to abut the heat exchange assembly along the fourth direction, and the abutment structure is configured to abut the heat exchange assembly along the first direction.

[0013] In some embodiments, a second flange portion is formed on the third side and is arranged around the second protrusion, and a second accommodating groove for accommodating the end of the coil unit is defined between the second flange portion and the second protrusion, and the inner peripheral wall of the second flange portion is used to support the outer shell of the coil unit along the fourth direction.

[0014] In some embodiments, the first protective pad is formed with a first extension portion on one side in the second direction, and the second protective pad is formed with a second extension portion on one side in the fourth direction. When the packaging assembly accommodates the coil unit, the first extension portion and the second extension portion are arranged opposite to each other to form an escape space for the pipeline avoiding the coil unit.

[0015] Compared with the prior art, the packaging assembly of the utility model has the following beneficial effects:

[0016] In the technical solution of the utility model, when packaging the coil unit, the first protective pad is arranged at one end of the coil unit along the length direction, the first side of the first protective pad contacts the coil unit, and the abutment structure of the first protective pad abuts the heat exchange component inside the coil unit.

[0017] It should be noted that the inventor found through observation that the end face of one end of the heat exchange assembly is V-shaped. When the height of the coil unit is large, the slope of the end face of the heat exchange assembly is large, and when the height of the coil unit is small, the slope of the end face of the heat exchange assembly is small. Based on this, a corresponding abutment structure is designed on the first protective pad according to the V-shaped end face of the heat exchange assembly with different slopes, and the abutment structure includes a first abutment surface, a second abutment surface, a first abutment portion, and a second abutment portion.

[0018] Specifically, when the coil unit has a smaller packaging height, since the inclination of the end face of the heat exchange component is smaller, the abutment structure abuts against the V-shaped end face of the heat exchange component through the first abutment surface and the second abutment surface, and the distance from the first side to the second side gradually decreases, so that the first abutment surface and the second abutment surface just match the V-shaped end face of the heat exchange component, ensuring that the first protective pad is not easy to shake, and the limiting effect on the heat exchange component is better.

[0019] When packaging a coil unit with a larger height, since the slope of the V-shaped end surface of the heat exchange component is larger, the abutment structure can abut against the V-shaped end surface of the heat exchange component through the first abutment portion and the second abutment portion. The first abutment portion is located at one end of the first abutment surface away from the second abutment surface, and the first abutment portion protrudes along the normal direction of the first abutment surface, so that the first abutment portion can abut against the V-shaped end surface with a larger slope. Similarly, the second abutment portion is located at one end of the second abutment surface away from the first abutment surface, and the second abutment portion protrudes along the normal direction of the second abutment surface, so that the first abutment portion can abut against the V-shaped end surface with a larger slope. By abutting the V-shaped end surface with the first abutment portion and the second abutment portion, it can be ensured that the first protective pad is not easy to shake, and the limiting effect on the heat exchange component is better. In general, there is no need to design two different packaging structures for the above two coil units with different heights, which can reduce manufacturing costs.

[0020] The utility model also provides a coil unit package, comprising a coil unit and the packaging assembly of the above embodiment, wherein the coil unit is accommodated in the packaging assembly.

[0021] Compared with the prior art, since the coil unit package of the present invention includes the packaging assembly of the above embodiment, it has the above beneficial effects, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Reference Figure 1 As shown, the coil unit package 1000 provided by the embodiment of the utility model includes a packaging component 100 and a coil unit 200. The coil unit 200 is packaged in the packaging component 100. It can be understood that the coil unit 200 is contained in the packaging component 100. In some embodiments, the coil unit 200 can be understood as an air duct machine.

[0048] The following first describes the structure of the lower coil unit 200. Fig.15 and Fig.16 As shown, the coil unit 200 includes an outer shell 210 and a heat exchange component 220. The outer shell 210 is a roughly cubic or rectangular structure. The outer shell 210 has a circle of outer peripheral walls. An inner cavity is formed in the outer shell 210. The heat exchange component 220 is located in the inner cavity of the outer shell 210. The heat exchange component 220 is a roughly triangular structure as a whole, which can be understood as a structure that is narrow at the top and wide at the bottom. The width of the heat exchange component 220 gradually increases from top to bottom. Both ends of the outer shell 210 in the up and down directions have openings connected to the inner cavity. It can be understood that the upper and lower ends of the outer shell 210 are open, and the heat exchange component 220 can be inserted into the opening and loaded into the inner cavity of the outer shell 210.

[0049] Reference Fig.17 and Fig.18 As shown, the coil unit 200 includes a heat exchange assembly 220, the coil unit 200 does not have a housing 210, and the heat exchange assembly 220 is generally triangular in structure, which can be understood as a structure that is narrow at the top and wide at the bottom, and the width of the heat exchange assembly 220 gradually increases from top to bottom. The heat exchange assembly 220 includes an evaporator assembly 221 and a water receiving tray assembly 222, the water receiving tray assembly 222 is located at the lower side of the evaporator assembly 221, and the water receiving tray assembly 222 is in a U-shaped structure.

[0050] In order to prevent the heat exchange assembly 220 from shaking during the transportation of the coil unit 200, in the related art, a foam pad is used to abut the end surface of the heat exchange assembly 220, so as to position the heat exchange assembly 220, so that the heat exchange assembly 220 is not easy to shake. It should be noted that for coil units 200 of different heights, the heights of the heat exchange assembly 220 inside are also different, which will cause the shape of the end surface of the heat exchange assembly 220 to change, making it difficult for the shape of the foam pad to match the different end surfaces well.

[0051] Based on this, the inventor found through observation that Fig.17 and Fig.18 As shown, the heat exchange assembly 220 includes an evaporator assembly 221, and the evaporator assembly 221 includes two evaporator bodies 2211. The two evaporator bodies 2211 are arranged to be inclined with each other and form an angle, so that the evaporator assembly 221 as a whole is an inverted V-shaped structure, and the end of the evaporator assembly 221 forms a V-shaped end surface 2212. Specifically, referring to Figure 2 As shown, the V-shaped end surface 2212 includes a first surface 2223 and a second surface 2224 , and the first surface 2223 and the second surface 2224 are inclined to each other and form an angle. Figure 2In the figure, when the height of the coil unit 200 is small, the height of the evaporator assembly 221 is small, and the angle between the two evaporator bodies 2211 is large, so that the slope of the V-shaped end surface 2212 formed at the upper end of the evaporator assembly 221 is small. It can be understood that the angle formed by the first surface 2223 and the second surface 2224 is small. Figure 8 In the embodiment, the height of the coil unit 200 is relatively large, the height of the evaporator assembly 221 is relatively large, and the angle between the two evaporator bodies 2211 is relatively small, so that the slope of the V-shaped end surface 2212 formed at the upper end of the evaporator assembly 221 is relatively large, which can be understood as the angle formed by the first surface 2223 and the second surface 2224 is relatively large, and for the coil unit 200 with a relatively large height, the length of the first surface 2223 and the length of the second surface 2224 are relatively large. Based on this, it can be considered to arrange two abutting parts with different height positions, so as to achieve the adaptation of the above two V-shaped end surfaces 2212 with different slopes.

[0052] Reference Figure 1 As shown, the packaging assembly 100 of this embodiment includes a first protective pad 110. It should be noted that the first protective pad 110 has a first direction and a second direction that are perpendicular to each other. Depending on the placement state of the coil unit package 1000, the actual orientations corresponding to the first direction and the second direction are also different. For example, referring to Figure 1 As shown, when the coil unit package 1000 is placed vertically, the first direction can be understood as the up-down direction. In the following, in conjunction with the accompanying drawings, the first direction is taken as the up-down direction and the second direction is taken as the horizontal direction. The coil unit 200 has a length direction. In the following, in conjunction with the accompanying drawings, the length direction of the coil unit 200 is taken as the up-down direction.

[0053] Reference Fig. 9 , Fig.11 and Fig.12As shown, in the up-down direction, the first protection pad 110 has a first side and a second side that are arranged opposite to each other, the first side can be understood as the lower side of the first protection pad 110, and the second side can be understood as the upper side of the first protection pad 110. An abutment structure is formed on the first side of the first protection pad 110, and the abutment structure is used to abut the heat exchange assembly 220, that is, the abutment structure is used to abut the V-shaped end surface 2212 of the evaporator assembly 221 of the heat exchange assembly 220. Specifically, the abutting structure includes a first abutting surface 1121 and a second abutting surface 1122, which are arranged opposite to each other in the left-right direction, and the distance from the first abutting surface 1121 to the second abutting surface 1122 gradually increases from the first side to the second side, which can be understood as the first abutting surface 1121 and the second abutting surface 1122 are arranged at an angle to each other, and the first abutting surface 1121 and the second abutting surface 1122 form a roughly inverted V-shape, which just matches the V-shaped end surface 2212 of the evaporator assembly 221. In order to match the V-shaped end surfaces 2212 with different slopes, on this basis, the abutting structure also includes a first abutting portion 1123 and a second abutting portion 1124.

[0054] Specifically, refer to Fig. 9 , Fig.11 and Fig.12 As shown, the first abutting portion 1123 is located at one end of the first abutting surface 1121 away from the second abutting surface 1122, and the second abutting portion 1124 is located at one end of the second abutting surface 1122 away from the first abutting surface 1121. It can also be understood that the first abutting portion 1123 is located at the upper end of the first abutting surface 1121, and the second abutting portion 1124 is located at the upper end of the second abutting surface 1122. The first abutting portion 1123 protrudes along the normal direction of the first abutting surface 1121, and the second abutting portion 1124 protrudes along the normal direction of the second abutting surface 1122. The normal direction of the first abutting surface 1121 can be understood as a direction perpendicular to the first abutting surface 1121, and the normal direction of the second abutting surface 1122 can be understood as a direction perpendicular to the second abutting surface 1122.

[0055] Reference Figure 1 As shown, Figure 1 The height of the coil unit 200 is small. When the packaging assembly 100 packages the coil unit 200 with a small height, refer to Figure 2As shown, the V-shaped end surface 2212 of the evaporator assembly 221 abuts against the first abutting surface 1121 and the second abutting surface 1122. Specifically, the first surface 2223 abuts against the first abutting surface 1121, and the second surface 2224 abuts against the second abutting surface 1122, which limits the evaporator assembly 221. In addition, neither the first abutting portion 1123 nor the second abutting portion 1124 contacts the evaporator assembly 221. There is a spacing between the first abutting portion 1123 and the evaporator assembly 221, and there is also a spacing between the second abutting portion 1124 and the evaporator assembly 221, so as to avoid hindering the first abutting surface 1121 and the second abutting surface 1122 from respectively cooperating with the evaporator assembly 221.

[0056] Figure 7 The height of the coil unit 200 is relatively large. When the packaging assembly 100 packages the coil unit 200 with a relatively large height, refer to Figure 8 As shown, since the length of the first surface 2223 and the length of the second surface 2224 are relatively large, the V-shaped end surface 2212 of the evaporator assembly 221 abuts against the first abutting portion 1123 and the second abutting portion 1124. Specifically, the first surface 2223 abuts against the first abutting portion 1123, and the second surface 2224 abuts against the second abutting surface 1122, which can increase the contact area between the abutting structure and the evaporator assembly 221. It should be noted that in the coil unit 200 with a larger packaging height, part of the first abutting surface 1121 and part of the second abutting surface 1122 can also maintain abutment with the V-shaped end surface 2212, which can further increase the contact area. The packaging assembly 100 of this embodiment is compatible with two types of coil units 200 with different packaging heights, improves packaging compatibility, does not need to set up two different packaging structures, and can reduce manufacturing costs.

[0057] In some embodiments, the first abutment portion 1123 and the second abutment portion 1124 can be constructed as a hemispherical structure, and the first abutment portion 1123 and the second abutment portion 1124 are both in point contact with the V-shaped end face 2212. The first abutment portion 1123 and the second abutment portion 1124 can be constructed as a semi-cylindrical structure, and the first abutment portion 1123 and the second abutment portion 1124 are both in line contact with the V-shaped end face 2212. The first abutment portion 1123 and the second abutment portion 1124 can also be constructed as a triangular, trapezoidal or square structure, and both are in surface contact with the V-shaped end face 2212.

[0058] In some embodiments, the first abutting surface 1121 and the second abutting surface 1122 can be configured as straight inclined surfaces or as curved surfaces with a certain curvature. In some embodiments, the first abutting surface 1121 and the second abutting surface 1122 can be symmetrically arranged with each other and have a relatively standardized shape, and the symmetry line of the first abutting surface 1121 and the second abutting surface 1122 extends in the up-down direction.

[0059] It should be noted that, in the up-down direction, the lowest position of the first abutting portion 1123 may be lower than the lowest position of the first abutting surface 1121, and the lowest position of the second abutting portion 1124 may be lower than the lowest position of the second abutting surface 1122. Alternatively, in the up-down direction, the lowest position of the first abutting surface 1121 is lower than the lowest position of the first abutting portion 1123, and the lowest position of the second abutting surface 1122 is lower than the lowest position of the second abutting portion 1124. The first abutting portion 1123 and the second abutting portion 1124 are arranged opposite to each other in the left-right direction, one right and one left, the first abutting portion 1123 is located at the left end of the first abutting surface 1121, and the second abutting portion 1124 is located at the right end of the second abutting surface 1122. From right to left, the first abutting portion 1123, the first abutting surface 1121, the second abutting portion 1124 and the second abutting surface 1122 are arranged in sequence.

[0060] Reference Figure 2 , Figure 8 and Fig.12 As shown, in some embodiments, the lower end of the first abutting portion 1123 is provided with a third abutting surface 1125, and the first abutting portion 1123 abuts against the evaporator assembly 221 through the third abutting surface 1125. Along the normal direction of the first abutting surface 1121, there is a spacing between the third abutting surface 1125 and the first abutting surface 1121. The first abutting surface 1121 and the third abutting surface 1125 can be constructed as inclined surfaces, and the inclination angle of the third abutting surface 1125 relative to the vertical direction is greater than the inclination angle of the first abutting surface 1121 relative to the vertical direction, which can better match the first surface 2223 with different inclinations. When the first abutting surface 1121 or the third abutting surface 1125 abuts against the first surface 2223, it is a surface contact, which can increase the contact area and has a better limiting effect on the evaporator assembly 221. This embodiment can be understood as configuring two inclined surfaces with different inclinations to match the first surface 2223 of the V-shaped end surface 2212 of the evaporator assembly 221.

[0061] Reference Figure 2 , Figure 8 and Fig.12As shown, in some embodiments, the lower end of the second abutting portion 1124 is provided with a fourth abutting surface 1126, and the second abutting portion 1124 abuts against the evaporator assembly 221 through the fourth abutting surface 1126. Along the normal direction of the second abutting surface 1122, there is a spacing between the fourth abutting surface 1126 and the second abutting surface 1122. The second abutting surface 1122 and the fourth abutting surface 1126 can be constructed as inclined surfaces, and the inclination angle of the fourth abutting surface 1126 relative to the vertical direction is greater than the inclination angle of the second abutting surface 1122 relative to the vertical direction, which can better match the second surface 2224 with different inclinations. When the second abutting surface 1122 or the fourth abutting surface 1126 abuts against the second surface 2224, it is a surface contact, which can increase the contact area and has a better limiting effect on the evaporator assembly 221. This embodiment can be understood as configuring two inclined surfaces with different inclinations to match the second surface 2224 of the V-shaped end surface 2212 of the evaporator assembly 221.

[0062] Specifically, refer to Fig.11 and Fig.12 As shown, three auxiliary lines X1, X2 and X3 are parallel to each other and extend in the up-down direction. The angle formed by the first abutting surface 1121 and X1 is α1, which can be understood as the inclination angle of the first abutting surface 1121 relative to the first direction. The angle formed by the second abutting surface 1122 and X1 is α2, which can be understood as the inclination angle of the second abutting surface 1122 relative to the first direction. The angle formed by the third abutting surface 1125 and X2 is α3, which can be understood as the inclination angle of the third abutting surface 1125 relative to the first direction. The angle formed by the fourth abutting surface 1126 and X3 is α4, which can be understood as the inclination angle of the fourth abutting surface 1126 relative to the first direction. Among them, α3 is greater than α1, α4 is greater than α2, α1 can be equal to α2, and α1 and α2 can also be unequal.

[0063] In some embodiments, the third abutting surface 1125 and the fourth abutting surface 1126 may be configured as straight inclined surfaces or inclined surfaces with a certain curvature. In some embodiments, the third abutting surface 1125 and the fourth abutting surface 1126 may be symmetrically arranged with respect to each other, and the third abutting surface 1125 and the fourth abutting surface 1126 may be symmetrically arranged with respect to the symmetry line of the first abutting surface 1121 and the second abutting surface 1122.

[0064] It can be understood that, in some embodiments, the first protection pad 110 and the second protection pad 120 are foam pieces made of foam material, which has low material cost, good structural strength, and is easy to manufacture, thereby saving manufacturing costs.

[0065] Reference Fig. 9As shown, in some embodiments, a first flange portion 111 and a first protrusion 112 are further formed on the first side of the first protective pad 110. It can be understood that the first flange portion 111 and the first protrusion 112 are located on the lower side of the first protective pad 110, and the abutment structure of the first protective pad 110 is arranged on the side of the first protrusion 112 away from the second side of the first protective pad 110. It can also be understood that the abutment structure is arranged on the lower side of the first protrusion 112. The first flange portion 111 is arranged around the first protrusion 112. The first flange portion 111 is located at the outer periphery of the first protrusion 112. It can be understood that the first flange portion 111 is arranged around an axis parallel to the up-down direction. The first flange portion 111 is extended along the circumference of the first protective pad 110. The first flange portion 111 is an annular structure. The first flange portion 111 is located at the edge of the first protective pad 110. The first protrusion 112 is located at the inner periphery of the first flange portion 111. A first receiving groove 113 is defined between the first flange portion 111 and the first protrusion 112. The first receiving groove 113 is an annular structure. The first receiving groove 113 is used to accommodate the end of the coil unit 200. In this embodiment, after the first protrusion 112 is provided, it is convenient for the abutment structure to extend into the opening of the outer shell 210 of the coil unit 200, so that the abutment structure can abut the heat exchange component 220. Refer to Figure 1 As shown, the inner circumferential wall of the first flange portion 111 can abut against the outer shell 210 of the coil unit 200 to achieve a better limiting effect and prevent the coil unit 200 from shaking.

[0066] In some embodiments, in the up-down direction, the lowest position of the first protrusion 112 may be lower than the lowest position of the first flange portion 111 .

[0067] Reference Fig.14 As shown, in some embodiments, the packaging assembly 100 further includes a second protective pad 120, and the second protective pad 120 has a third direction and a fourth direction perpendicular to each other. According to different placement states of the coil unit package 1000, the actual orientations corresponding to the third direction and the fourth direction are also different. For example, when the coil unit package 1000 is placed vertically, the third direction can be understood as the up-down direction. In conjunction with the accompanying drawings, the third direction is taken as the up-down direction and the fourth direction is taken as the horizontal direction.

[0068] Specifically, in the up-down direction, the second protection pad 120 has a third side and a fourth side arranged opposite to each other, and a second flange portion 121 is formed on the third side of the second protection pad 120. It can be understood that the second flange portion 121 is formed on the upper side of the second protection pad 120, and the second flange portion 121 is arranged around an axis parallel to the third direction. It can also be understood that the second flange portion 121 is extended around the circumference of the second protection pad 120, and the second flange portion 121 is an annular structure. In this embodiment, the inner peripheral wall of the second flange portion 121 can abut against the outer shell 210 of the coil unit 200, thereby limiting the outer shell 210.

[0069] It should be noted that when the packaging assembly 100 packages the coil unit 200, the first protection pad 110 and the second protection pad 120 are arranged on opposite sides of the coil unit 200, the first protection pad 110 is located at the upper end of the coil unit 200, thereby protecting the upper end of the coil unit 200, and the second protection pad 120 is located at the lower end of the coil unit 200, thereby protecting the lower end of the coil unit 200. The upper end of the coil unit 200 is inserted into the first receiving groove 113, and the abutting structure abuts the heat exchange assembly 220 downward.

[0070] It should be noted that in some transportation scenarios, there is a need to package and transport the coil unit 200 with or without the outer shell 210. The coil unit 200 without the outer shell 210 can be understood as an exposed heat exchange component 220. The outer surface size of the coil unit 200 without the outer shell 210 is smaller than that of the coil unit 200 with the outer shell 210, which makes it difficult for the first flange 111 and the second flange 121 to limit the coil unit 200, and there is a risk of free movement of the coil unit 200. Specifically, Fig.15 The coil unit 200 in the embodiment has a housing 210, Fig.17 The coil unit 200 in the embodiment does not have a housing 210 .

[0071] Reference Fig.17 As shown, the inventors found through observation that the heat exchange assembly 220 also includes a water receiving pan assembly 222, which is located at the lower side of the evaporator assembly 221. The water receiving pan assembly 222 is in a U-shaped structure. Regardless of whether the coil unit 200 is provided with a housing 210 or not, the size of the water receiving pan assembly 222 is unchanged. Based on this, it is possible to consider arranging a structure that abuts against the water receiving pan assembly 222 on the second protective pad 120.

[0072] Reference Fig.14 As shown, in some embodiments, the second protection pad 120 is formed with a second convex portion 122 on the third side, which can be understood as follows: the second convex portion 122 is located on the upper side of the second protection pad 120, the second convex portion 122 is located on the inner periphery of the second flange portion 121, the second flange portion 121 is arranged around the second convex portion 122, and a second receiving groove 123 is defined between the second flange portion 121 and the second convex portion 122, and the second receiving groove 123 is an annular structure. Specifically, the second convex portion 122 has an outer peripheral wall, and the outer peripheral wall of the second convex portion 122 is arranged around an axis parallel to the up-down direction, which can also be understood as follows: the outer peripheral wall of the second convex portion 122 is arranged along the circumference of the second protection pad 120.

[0073] It should be noted that Figure 1 The coil unit 200 in the embodiment has a housing 210, Figure 5The coil unit 200 in the package assembly 100 does not have a housing 210. When the packaging assembly 100 packages the coil unit 200 without or with a housing 210, the upper end of the heat exchange assembly 220 of the coil unit 200 abuts against the abutment structure of the first protective pad 110, and the lower end of the coil unit 200 is inserted into the second receiving groove 123, so that the position can be limited in the up and down directions. Figure 3 and Figure 6 As shown, the second protrusion 122 extends into the water tray assembly 222, and the outer peripheral wall of the second protrusion 122 abuts against the inner peripheral wall of the water tray assembly 222 in the horizontal direction, which can achieve horizontal limitation and prevent the coil unit 200 from moving freely during transportation. The coil unit 200 with and without the outer shell 210 can be packaged compatibly, further improving the packaging compatibility, and there is no need to set two different packaging structures to package the coil unit 200 with and without the outer shell 210, which can reduce the manufacturing cost.

[0074] It should be noted that the key structure of this embodiment is the abutment structure of the first protective pad 110 and the second convex portion 122 of the second protective pad 120, which realizes compatibility with coil units 200 with different packaging heights and coil units 200 with shells 210 and shells 210, and has good packaging compatibility. In addition, it is also feasible that the first protective pad 110 and the second protective pad 120 do not have the first flange portion 111 and the second flange portion 121 of the above embodiment. After the above-mentioned first flange portion 111 and the second flange portion 121 are provided, a better limiting effect can be achieved when packaging the coil unit 200 with the shell 210.

[0075] It can be understood that in the above embodiment, the entire coil unit package 1000 can be understood to be placed vertically. At this time, the second protective pad 120 is located at the bottom of the coil unit 200, and the second protective pad 120 bears the gravity of the coil unit 200, and the second protective pad 120 supports the coil unit 200. In some other embodiments, the entire coil unit package 1000 can also be placed horizontally, for example, the outer peripheral wall of the outer shell 210 of the coil unit 200 is set downward, and the first protective pad 110 and the second protective pad 120 are respectively located on the left and right sides of the coil unit 200. At this time, the first flange part 111 of the first protective pad 110 and the second flange part 121 of the second protective pad 120 jointly bear the gravity of the coil unit 200, the abutting structure of the first protective pad 110 abuts the evaporator assembly 221 to the right, and the outer peripheral wall of the second protrusion 122 abuts the water tray assembly 222 in the up and down direction. It is understandable that when the coil unit package 1000 is placed in different ways, the first direction and the second direction of the first protective pad 110 and the third direction and the fourth direction of the second protective pad 120 will be different accordingly, which can be determined according to the actual scene. For example, when the coil unit package 1000 is placed vertically, the first direction and the third direction are up and down directions, and the second direction and the fourth direction are horizontal directions, which can be left and right directions or front and back directions. When the coil unit package 1000 is placed horizontally, the first direction and the third direction are horizontal directions, which can be left and right directions or front and back directions, and the second direction and the fourth direction are up and down directions.

[0076] Reference Figure 1 As shown, in some embodiments, the packaging assembly 100 also includes a carton 130. During packaging, the upper and lower ends of the coil unit 200 are first loaded into the first protective pad 110 and the second protective pad 120 respectively, and then the whole formed by the coil unit 200, the first protective pad 110 and the second protective pad 120 is loaded into the carton 130. When the carton 130 is impacted, the first protective pad 110 and the second protective pad 120 can protect the upper and lower ends of the coil unit 200, and the first flange portion 111 and the second flange portion 121 can form a certain distance between the coil unit 200 and the carton 130 to prevent the carton 130 from directly hitting the coil unit 200 when it is impacted.

[0077] It should be noted that in some prior arts, the coil unit 200 is usually packaged with a combination of honeycomb cardboard, EVA cardboard and hard paper corners, and needs to be fixed with hot melt adhesive. After a period of time, the hot melt adhesive is easy to fall off, resulting in poor packaging quality, and the above combination also has poor protective effect on the coil unit 200.

[0078] Compared with the above-mentioned prior art, this embodiment does not need to perform the hot melt adhesive fixing step, which simplifies the packaging steps, is more convenient, and has higher packaging protection quality.

[0079] It is understandable that, referring to Fig.13 and Fig.11 As shown, in some embodiments, a first groove 114 and a second groove 115 are provided on the second side of the first protective pad 110, and the position of the first groove 114 corresponds to the position of the first receiving groove 113, and the second groove 115 corresponds to the position of the first convex portion 112. It can also be understood that the second groove 115 and the first convex portion 112 are arranged opposite to each other in the up-down direction. Moreover, in the up-down direction, the maximum depth of the second groove 115 is less than the maximum depth of the first groove 114. In this embodiment, the first groove 114 and the second groove 115 can be understood as being formed after removing part of the material of the first protective pad 110, which can reduce the material used for the first protective pad 110 and reduce the manufacturing cost, and also reduce the weight of the first protective pad 110 and reduce the transportation load. In addition, the depth of the second groove 115 is large, so that the volume of the second groove 115 is large, and the wire controller of the coil unit 200 can be placed in the second groove 115, and the wire controller can be clamped with the inner wall of the second groove 115, so as to realize the joint packaging of the wire controller and improve the packaging compatibility.

[0080] It should be noted that, in the above embodiment, the second groove 115 and the first protrusion 112 are arranged opposite to each other in the up and down directions, that is, the second protrusion 112 is located on the lower side of the first protective pad 110, and the second groove 115 is located on the upper side of the first protective pad 110, so that the wall thickness of the first protective pad 110 at the position of the first protrusion 112 is relatively uniform, ensuring that defects are not easily generated during the manufacturing process.

[0081] It should be noted that when the first protection pad 110 and the second protection pad 120 are made of foam material, if the wall thickness of the first protection pad 110 and the second protection pad 120 is not uniform, during the cooling process of the foam melt, the shrinkage rates of the thick-walled part and the thin-walled part of the foam part are different, which may cause the product to warp, deform, etc., and may also cause stress inside the product, reducing the strength and rigidity of the product. During the injection molding process, the foam melt has a large flow resistance in the thick-walled part, which may easily cause problems such as insufficient filling and bubbles.

[0082] It is understandable that, referring to Fig.15 As shown, in some embodiments, the coil unit 200 includes a first pipeline 223, and part of the first pipeline 223 is located at the upper end of the evaporator assembly 221. When the coil unit 200 has an outer shell 210, the first pipeline 223 is located in the inner cavity of the outer shell 210. When the length of the first protrusion 112 in the front-to-back direction is large, the first pipeline 223 may hinder the first protrusion 112 from cooperating with the evaporator assembly 221.

[0083] Based on this, refer to Fig. 9As shown, in some embodiments, a side of the first protrusion 112 abutting against the heat exchange component 220 is provided with an avoidance groove 1227, the avoidance groove 1227 is recessed upward, and the avoidance groove 1227 is used for the first pipeline 223 of the coil unit 200 to pass through, so as to prevent the first pipeline 223 from obstructing the abutment between the first protrusion 112 and the evaporator component 221. Fig.12 As shown, in some embodiments, the avoidance groove 1227 divides the first protrusion 112 into a first section structure 1228 and a second section structure 1229, and the avoidance groove 1227 is located between the first section structure 1228 and the second section structure 1229. In the front-to-back direction, the length of the first section structure 1228 is smaller than the length of the second section structure 1229, and the lower ends of the first section structure 1228 and the second section structure 1229 are both abutted against the upper end of the evaporator assembly 221, which can increase the contact area between the first protrusion 112 and the evaporator assembly 221 and improve the limiting effect.

[0084] It is understandable that, referring to Fig.10 and Fig.13 As shown, in some embodiments, in the up-down direction, the upper side of the first protective pad 110 is provided with a third groove 116, which can also be understood as the end of the first protective pad 110 away from the second protective pad 120 is provided with the third groove 116, and the third groove 116 is formed by removing part of the material of the first protective pad 110, which can save the material of the first protective pad 110 and reduce the material cost, and can also reduce the weight of the first protective pad 110 and reduce the transportation load. In some embodiments, specifically, the third groove 116 and the avoidance groove 1227 are arranged relative to each other in the up-down direction, so that the wall thickness of the first protective pad 110 at the position of the avoidance groove 1227 is relatively uniform, ensuring that it is not easy to produce defects during the manufacturing process. It should be noted that the dimensions of the third groove 116 in the left-right direction and the front-back direction correspond to the dimensions of the avoidance groove 1227 in the left-right direction and the front-back direction. In some embodiments, the cross-sectional contour line of the third groove 116 can be circular, square, or track-shaped.

[0085] It is understandable that, referring to Figure 4 As shown, in some embodiments, the coil unit 200 includes a second pipe 224, and the second pipe 224 is located outside the shell 210. When the coil unit 200 is loaded into the carton 130, the second pipe 224 is easy to touch the carton 130, affecting the packaging compatibility. It is necessary to consider how to be compatible with such a coil unit 200.

[0086] Based on this, refer to Fig. 9As shown, in some embodiments, the first protection pad 110 is provided with a first extension portion 1112, and the first extension portion 1112 is located at one side of the first protection pad 110 along the second direction. It can also be understood that the first extension portion 1112 is located at the front side of the first protection pad 110. The second protection pad 120 is provided with a second extension portion 1212, and the second extension portion 1212 is located at one side of the second protection pad 120 along the fourth direction. Fig.14 As shown, it can also be understood that the second extension portion 1212 is located at the front side of the second protection pad 120 .

[0087] In this embodiment, by providing the first extension portion 1112 and the second extension portion 1212, after the coil unit 200 is packaged with the packaging assembly 100, Figure 4 As shown, the first extension portion 1112 and the second extension portion 1212 are arranged opposite to each other one above the other, so that an escape space 127 is formed between the first extension portion 1112 and the second extension portion 1212, so that the second pipeline 224 of the coil unit 200 is located in the escape space 127, which can prevent the second pipeline 224 from directly contacting the carton 130, protect the second pipeline 224, and enhance packaging compatibility. It should be noted that in some other embodiments, the escape space 127 can also be used to avoid other structures of the coil unit 200 protruding from the housing 210. The extension lengths of the first extension portion 1112 and the second extension portion 1212 in the front-to-back direction, the left-to-right direction, or the up-to-down direction are not limited. For example, the extension length of the first extension portion 1112 can be less than or equal to the length of the first protective pad 110 in the left-to-right direction, and the extension length of the second extension portion 1212 can be less than or equal to the length of the second protective pad 120 in the left-to-right direction.

[0088] From another perspective, the first extension portion 1112 can be understood as a partial structure of the first flange portion 111, and the second extension portion 1212 can be understood as a partial structure of the second flange portion 121. Fig. 9 As shown, in some embodiments, the first flange portion 111 includes a first main body portion 1111 and a first extension portion 1112. The first main body portion 1111 is an annular structure, which can be understood as a U-shaped structure. The first main body portion 1111 and the first extension portion 1112 are an integral structure. The first extension portion 1112 is connected to one side of the first main body portion 1111 along the front-to-back direction. The first extension portion 1112 extends along the left-to-right direction. The first extension portion 1112 can be understood as a strip-shaped structure. The first extension portion 1112 can play a role in locally thickening the first flange portion 111, thereby ensuring that the structural strength of the first flange portion 111 is better.

[0089] Reference Fig.14As shown, the second flange portion 121 includes a second main body portion 1211 and a second extension portion 1212. The second main body portion 1211 is an annular structure, which can be understood as a U-shaped structure. The second main body portion 1211 and the second extension portion 1212 are connected as an integral structure. The second extension portion 1212 is connected to one side of the second main body portion 1211 along the front-to-back direction. The second extension portion 1212 extends along the left-to-right direction. The second extension portion 1212 can be understood as a strip-shaped structure. The second extension portion 1212 can play a role in locally thickening the second flange portion 121, thereby ensuring that the second flange portion 121 has better structural strength.

[0090] It should be noted that after the first extension portion 1112 is arranged on the first protection pad 110 and the second extension portion 1212 is arranged on the second protection pad 120, the volume of the first protection pad 110 and the volume of the second protection pad 120 increase, and the weight of the first protection pad 110 and the second protection pad 120 also increases accordingly.

[0091] In order to reduce the weight of the first protection pad 110 and the second protection pad 120, refer to Fig. 9 and Fig.14 As shown, in some embodiments, a fourth groove 117 is provided at the lower side of the first extension portion 1112, and the fourth groove 117 does not penetrate the first extension portion 1112, thereby ensuring that the structural strength of the first protection pad 110 is good, and a seventh groove 126 is provided at the upper side of the second extension portion 1212, and the seventh groove 126 does not penetrate the second extension portion 1212, thereby ensuring that the structural strength of the second protection pad 120 is good. After the packaging assembly 100 packages the coil unit 200, the notch of the fourth groove 117 and the notch of the seventh groove 126 are arranged opposite to each other, that is, the notch of the fourth groove 117 is arranged downward, and the notch of the seventh groove 126 is arranged upward. The fourth groove 117 is formed by removing part of the material of the first extension part 1112, and the seventh groove 126 is formed by removing part of the material of the second extension part 1212, which can reduce the weight of the first protection pad 110 and the second protection pad 120, making the first protection pad 110 and the second protection pad 120 lighter, more convenient to take and assemble, and reducing the transportation load. At the same time, the material used for the first protection pad 110 and the second protection pad 120 can be reduced, reducing the material cost. In some embodiments, the number of the fourth groove 117 and the number of the seventh groove 126 can be multiple, and the cross-sectional contour line of the fourth groove 117 and the cross-sectional contour line of the seventh groove 126 can be circular, square, or track-shaped.

[0092] It is understandable that, referring to Fig.14As shown, in some embodiments, the second convex portion 122 is configured as an annular structure. It can be understood that the second convex portion 122 has a zigzag structure, and a fifth groove 124 is formed inside the second convex portion 122. A sixth groove 125 is formed on the side wall of one side of the fifth groove 124 in the up and down direction. It can be understood that the sixth groove 125 is provided on the side wall of the lower side of the fifth groove 124. The sixth groove 125 is formed by removing a part of the material of the second protective pad 120, which can save the material of the second protective pad 120, reduce the material cost, and also reduce the weight of the second protective pad 120, making it lighter and more convenient for packaging operations and reducing the transportation load. In addition, compared with setting the sixth groove 125 on the second convex portion 122 in this embodiment, it is not necessary to remove a part of the material of the second convex portion 122, which can ensure that the structural strength of the second convex portion 122 is better. In some embodiments, the sixth groove 125 does not penetrate the second protective pad 120 to ensure better structural strength of the second protective pad 120. The number of the sixth grooves 125 can be multiple, and the cross-sectional contour line of the sixth groove 125 can be in shapes such as circular, square or racetrack-shaped.

[0093] It can be understood that since the first protective pad 110 is provided with the avoidance groove 1227, the first protective pad 110 can only be matched with the coil unit 200 in a specific direction and cannot be installed reversely.

[0094] Based on this, referring to Fig.10 As shown, in some embodiments, the upper end of the first protective pad 110 is provided with an identification portion 118. The identification portion 118 can be in shapes such as arrow-shaped, V-shaped or triangular, which can play an identification role. The identification portion 118 is used to identify the installation direction of the first protective pad 110 to facilitate finding the position of the first protective pad 110.

[0095] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0096] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0097] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
