Description
Technical Field
[0001] The utility model relates to the field of packaging and transportation of heat exchanger cores, and particularly relates to a packaging box for a vehicle heat exchanger core assembly and a packaging structure for the vehicle heat exchanger core assembly. Background Art
[0002] The vehicle heat exchanger core assembly is a core component for heat exchange in a vehicle air conditioner, including a heater core and an evaporator core. Specifically, the heat exchanger core assembly mainly consists of a core body, fins, flat tubes, and inlet and outlet water pipes. The core body and the pipes are rigidly connected by brazing, and the production process requirements are extremely strict. During packaging and transportation, due to local stress impact, cracks are likely to occur, resulting in major defects such as refrigerant leakage and coolant leakage. At the same time, the fin thickness is only 0.07 mm, the flat tubes have high precision and strong deformability, and during packaging and transportation, being collided or extruded will cause irreversible losses such as collapse, deformation, and distortion.
[0003] Currently, when packaging the heat exchanger core assembly, one heat exchanger core assembly is placed in one cardboard box. When placing, it is placed with the inlet and outlet water pipes facing up and the core body in contact with the bottom of the box. This method cannot effectively protect the fins on the core body, occupies a large space, wastes packaging materials, and increases the transportation burden. At the same time, there are also some heat exchanger core assemblies with detachable connection of the inlet and outlet water pipes from the heat exchanger core. During transportation packaging, the heat exchanger core and the inlet and outlet water pipes are packaged separately, which can effectively save packaging materials and transportation costs. However, this method still requires technicians to assemble the pipes after reaching the destination. At the same time, the heat exchanger cores are transported overlappingly, and the problem that the fins are easily damaged by extrusion cannot be solved. In view of the above problems, the applicant considered designing a cardboard box and packaging structure that can effectively protect the fins of the heat exchanger core, effectively and flexibly position the heat exchanger core, and install multiple heat exchanger core assemblies in one cardboard box at one time. Summary of the Invention
[0004] Aiming at the above deficiencies existing in the prior art, the purpose of the present utility model is to provide a packaging box for a vehicle heat exchanger core assembly and a packaging structure for the vehicle heat exchanger core assembly, so as to solve the problems that the existing heat exchanger core assembly cannot effectively protect the fins on the heat exchanger core during packaging and has a relatively high transportation cost.
[0005] To solve the above technical problems, the present utility model adopts the following technical solutions:
[0006] A packaging box for a vehicle heat exchanger core assembly, comprising a carton with an internal cavity, and a product positioning member made of a flexible material is assembled inside the carton. The product positioning member includes a flexible bottom plate that is clamped and fitted with the bottom of the carton. A separating boss protrudes upward from the middle of the flexible bottom plate. At least one positioning plate is further provided on the flexible bottom plate on the left and right sides of the separating boss. A heat exchanger core placement groove is formed between the positioning plate and the adjacent side wall of the carton, between two adjacent positioning plates, and between the positioning plate and the separating boss. The length of the heat exchanger core placement groove is greater than the length of the heat exchanger core to be installed, the width is equal to or greater than the thickness of the heat exchanger core to be installed, and the height is less than the width of the heat exchanger core to be installed. Above the separating boss and above one end of the heat exchanger core placement groove in the length direction, a placement space for the inlet and outlet pipes is jointly formed. In this way, when packaging the heat exchanger core assembly, first place the product positioning member in the carton, and then place the heat exchanger cores of each heat exchanger core assembly one by one in the heat exchanger core placement grooves and stagger them. This vertical and staggered placement method of the heat exchanger cores can effectively save space. Adjacent two heat exchanger core assemblies are separated by the positioning plate or the separating boss, and there is no heavy pressure on each other, which can effectively avoid the problem of fin deformation of the heat exchanger core due to overlapping placement. And it does not need to be assembled again after being transported to the destination, which is convenient for transportation. The product positioning member used is made of a flexible material, and the carton is a traditional carton. Therefore, after the heat exchanger core placement groove is filled with the heat exchanger core, even if there is a small shake, it will not cause damage to the heat exchanger core. The length of the heat exchanger core placement groove is greater than the length of the heat exchanger core in the heat exchanger core assembly to be placed, so as to provide enough space for the staggered placement of the heat exchanger core assembly. The width of the heat exchanger core placement groove is greater than or equal to the thickness of the heat exchanger core, that is, it can adapt to the placement of heat exchanger cores of different models. After the height of the heat exchanger core placement groove is less than the width of the heat exchanger core (i.e., the placement height), it can provide enough space for the inlet and outlet pipes to extend, so that the inlet and outlet pipes can be placed towards the separating boss direction without interference with the inlet and outlet pipes.
[0007] Further, the product positioning member is made of cardboard or foam board or rubber. In this way, the cardboard has low production cost, has a certain anti-collision performance, and also has a certain supporting force, which can meet the protection and clamping placement of the heat exchanger core assembly. The foam board has the characteristics of low cost and easy shaping, and also has anti-collision performance and strength, but it is not easy to degrade. And rubber also has flexibility and can play an anti-collision role, but the production cost is slightly higher than that of cardboard and foam board.
[0008] Further, a flexible anti-collision pad is clamped in one or each heat exchanger core placement groove. In this way, after setting the flexible anti-collision pad, flexible anti-collision pads with different thicknesses can be placed according to the thickness of the heat exchanger core in the heat exchanger core assembly to be placed, so that the heat exchanger core can be clamped in the heat exchanger core placement groove and will not shake and displace during the handling process.
[0009] Further, above the product positioning member inside the carton, there is also a collision prevention plate for protecting the top of the placed heat exchanger core assembly. In this way, after the collision prevention plate is provided above the product positioning member, it can protect the top of the heat exchanger core assembly, increase the top protection, and make the top have sufficient supporting force when the cartons are stacked during the transfer process.
[0010] Further, the collision prevention plate is rectangular or L-shaped or inverted U-shaped or box-shaped with an open bottom end. In this way, when the collision prevention plate is rectangular, the material used is the least. It can not only achieve the effect of protecting the product and supporting the box placed above it, but also has the lowest cost. When the collision prevention plate is set to be L-shaped or U-shaped or box-shaped, in addition to increasing the protection ability and supporting force above the box, it can also protect other sides, providing more comprehensive protection for the products inside the carton, but the cost is higher than that of the rectangular collision prevention plate.
[0011] A packaging structure for a heat exchanger core assembly includes a plurality of heat exchanger core assemblies and a heat exchanger core assembly packing box as described above. The heat exchange cores of the heat exchanger core assemblies are correspondingly placed in respective heat exchange core placement grooves, and the inlet and outlet water pipes of each heat exchanger core assembly are located above and face the partition boss; the inlet and outlet water pipes of the heat exchanger core assemblies on the left and right sides of the partition boss are respectively located at both ends of the heat exchange core placement groove, and two adjacent heat exchanger core assemblies on the same side are placed in a staggered manner. In this way, when packing, the heat exchange cores of the heat exchanger core assemblies are stuck in the heat exchange core placement grooves, and the heat exchanger cores on the same side are placed in a staggered manner, so that after the inlet and outlet water pipes of each heat exchanger core assembly are placed in a staggered manner, there is sufficient placement space and no interference will occur. The inlet and outlet water pipes of the heat exchanger core assemblies on both the left and right sides face the partition boss and are respectively located at both ends of the heat exchange core placement groove, making the placement space above the partition boss more evenly and reasonably distributed, and the overall placement space more compact.

[0020] Such as Figures 1-5As shown, the vehicle heat exchanger core assembly packaging box provided in this embodiment includes a carton 1 with a built-in cavity, and a product positioning member 3 made of flexible material is installed in the carton 1, and the product positioning member 3 includes a flexible bottom plate 31 that is clamped with the bottom of the carton 1, and the middle part of the flexible bottom plate 31 protrudes upward to form a partition boss 32. At least one positioning plate 33 is also provided on the left and right sides of the partition boss 32 and on the flexible bottom plate 31. A heat exchange core placement groove 34 is formed between the positioning plate 33 and the adjacent side wall of the carton 1, between two adjacent positioning plates 33, and between the positioning plate 33 and the partition boss 32. The length of the heat exchange core placement groove 34 is greater than the length of the heat exchange core 21 to be installed, the width is equal to or greater than the thickness of the heat exchange core to be installed, and the height is less than the width of the heat exchange core to be installed; above the partition boss 32 and above one end of the heat exchange core placement groove 34 in the length direction jointly form an inlet and outlet water pipe placement space. In this way, when packaging the heat exchanger core assembly 2, the product positioning member 3 is first placed in the carton 1, and then the heat exchange cores of each heat exchanger core assembly 2 are placed in the heat exchange core placement groove 34 one by one, and staggered. This method of vertically staggering the heat exchanger core can effectively save space. The two adjacent heat exchanger core assemblies 2 are separated by the positioning plate 33 or the separation boss 32, and there is no heavy pressure on each other, which can effectively avoid the problem of fin deformation of the heat exchange core fins due to overlapping placement, and there is no need to assemble again after transporting to the destination, which is convenient for transportation. The product positioning member 3 used is made of flexible material, and the carton 1 is a traditional carton, so that the heat exchange core placement groove 34 formed will not cause damage to the heat exchange core even if there is a small shake after the heat exchange core is placed. The length of the heat exchange core placement groove 34 is greater than the length of the heat exchange core in the placed heat exchange core assembly, thereby providing sufficient space for the staggered placement of the heat exchange core assembly. The width of the heat exchange core placement groove 34 is greater than or equal to the thickness of the heat exchange core, that is, it can adapt to the placement of heat exchange cores of different models. When the height of the heat exchange core placement groove 34 is less than the width of the heat exchange core (that is, the placement height), it can provide sufficient extension space for the inlet and outlet water pipes 22, so that the inlet and outlet water pipes 22 can be placed in the direction of the partition boss 32 without interfering with the inlet and outlet water pipes 22.
[0021] The product positioning member 3 is made of cardboard, foam board or rubber. When the product positioning member 3 is made of cardboard, the flexible bottom plate 31, the partition boss 32 and the positioning plate 33 of the product positioning member 3 are formed by folding a piece of cardboard multiple times and then bonding, or are formed by bonding multiple pieces of cardboard. When the product positioning member 3 is made of foam board, the product positioning member 3 is formed by cutting a piece of foam block, or the product positioning member 3 is directly formed by bonding multiple pieces of foam board. When the product positioning member 3 is made of rubber, it can be directly formed by hot plastic molding with a mold. The cardboard has a low production cost, has a certain anti-collision performance, and also has a certain supporting force, which can meet the protection and clamping placement of the heat exchanger core assembly 2. The foam board has the characteristics of low cost and easy shaping, and also has anti-collision performance and strength, but it is not easy to degrade. And rubber is also flexible and can play an anti-collision role, but the production cost is slightly higher than that of cardboard and foam board.
[0022] As Figure 4 , Figure 5 shown, the product positioning member 3 in this embodiment can package heat exchanger core assemblies 2 of different models. The width of the partition bump can be designed according to the extending length of the inlet and outlet water pipes 22. In specific implementation, different models of heat exchanger core assemblies 2 can also be packaged by replacing the product positioning member 3. If a product positioning member 3 is used to assemble heat exchanger core assemblies 2 of different models, the width of the heat exchanger core placement groove 34 to be set should be set as the width of the product with the largest thickness. Thus, after the heat exchanger core is placed, there will be a certain gap between it and the heat exchanger core placement groove 34. To avoid the displacement of the heat exchanger core assembly during handling due to the above gap, a flexible anti-collision pad (not shown in the figure) is clamped in one or each heat exchanger core placement groove 34. Specifically, the flexible anti-collision pad can also be clamped in the heat exchanger core placement groove 34 and placed at one end of the heat exchanger core assembly to position the end of the heat exchanger core assembly. In this way, after the flexible anti-collision pad is set, flexible anti-collision pads of different thicknesses can be placed according to the thickness of the heat exchanger core in the placed heat exchanger core assembly 2, so that the heat exchanger core can be clamped tightly in the heat exchanger core placement groove 34 and there will be no shaking and displacement during handling.
[0023] When shipping in boxes, the boxes will overlap with each other. To avoid causing greater extrusion to the products at the lower end after overlapping transportation, a collision-proof board 4 for protecting the top of the placed heat exchanger core assembly 2 is also provided above the product positioning member 3 in the cardboard box 1 (as Figure 6 shown). In this way, after the collision-proof board 4 is provided above the product positioning member 3, it can protect the top of the heat exchanger core assembly 2, increase the protection of the top, and make the top have sufficient supporting force when the boxes overlap during the transfer process.
[0024] Specifically, the anti-collision plate 4 in this embodiment is rectangular and adapted to the length and width of the inner cavity of the box. In specific implementation, the anti-collision plate 4 can be set as an L shape, an inverted U shape, or a box-shaped body with an open bottom end. The anti-collision plate 4 can be connected to the flexible bottom plate 31 or the positioning plate 33, or can be unconnected and only closely attached to the product. In this way, when the anti-collision plate 4 is rectangular, the material used is the least. It can not only achieve the protection of the product and the support of the box placed above it, but also minimize the cost. When the anti-collision plate 4 is set as an L shape, a U shape, or a box shape, in addition to increasing the protection ability and support force above the box, it can also protect other sides, providing more comprehensive protection for the products in the carton 1, but the cost is higher than that of the rectangular anti-collision plate 4.
[0025] The packaging structure for packing multiple heat exchanger core assemblies 2 using the above heat exchanger core assembly packing box is as follows: The packaging structure includes multiple heat exchanger core assemblies 2 and a heat exchanger core assembly packing box as described above. The heat exchange cores of the heat exchanger core assemblies 2 are correspondingly placed in the respective heat exchange core placement grooves 34, and the inlet and outlet water pipes 22 of each heat exchanger core assembly 2 are located above and are arranged towards the partition boss 32. The inlet and outlet water pipes 22 of the heat exchanger core assemblies 2 on the left and right sides of the partition boss 32 are respectively located at both ends of the heat exchange core placement groove 34, and two adjacent heat exchanger core assemblies 2 on the same side are placed in a staggered manner. In this way, when packing, the heat exchange cores of the heat exchanger core assemblies 2 are stuck in the heat exchange core placement grooves 34, and the heat exchanger cores on the same side are placed in a staggered manner, so that after the inlet and outlet water pipes 22 of each heat exchanger core assembly 2 are placed in a staggered manner, there is sufficient placement space and no interference will occur. The inlet and outlet water pipes 22 of the heat exchanger core assemblies 2 on the left and right sides are both arranged towards the partition boss 32 and are respectively located at both ends of the heat exchange core placement groove 34, making the placement space above the partition boss 32 more evenly and reasonably distributed, and the overall placement space more compact.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Those of ordinary skill in the art should understand that any modifications or equivalent replacements made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions should be covered by the scope of the claims of the present invention.
