[0002] The motorcycle heat exchange system is a key component of the motorcycle, and the design of its appearance structure, size and mounting mode constitutes a complete whole with the whole vehicle, and is an important part of the whole vehicle. At present, motorcycles are developing more precisely, and the design of parts including the heat exchange system is more compact, small in size and higher in strength. However, the existing motorcycle heat exchangers are mostly complex in structure, which increases the production difficulty and production cost, and it is not convenient to form heat exchangers of different specifications according to user needs. At the same time, the water channel and the oil channel are mostly separated, and the oil-water isolation sealing effect is poor. Therefore, in view of the above technical problems, a cross laminated heat exchanger is proposed. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model provides a cross laminated heat exchanger, which is simple in structure, reduces the production difficulty and production cost, and is convenient for forming heat exchangers of different specifications according to user needs. At the same time, the water channel and the oil channel are independently formed, and the oil-water isolation sealing effect is good.

[0004] The cross laminated heat exchanger comprises:

[0005] The heat exchanger core body comprises a first heat exchange component and a second heat exchange component, the first heat exchange component comprises a plurality of groups of arrayed first heat exchange assemblies, the second heat exchange component comprises a plurality of groups of arrayed second heat exchange assemblies, and the first heat exchange assembly and the second heat exchange component each have a cavity and two groups of through holes communicating with the cavity;

[0006] The plurality of groups of first heat exchange assemblies and the plurality of groups of second heat exchange assemblies are cross laminated, so that the plurality of groups of through holes at the upper and lower ends of the heat exchanger core body are communicated to form a first flow channel, the plurality of groups of through holes at the front and rear ends of the heat exchanger core body are communicated to form a second flow channel, and the first heat exchange assembly and the second heat exchange assembly form an included angle, so that the first flow channel and the second flow channel are axially staggered.

[0007] The cross laminated heat exchanger has the following advantages:

[0008] The heat exchanger core is formed by cross-laminating a plurality of first heat exchange assemblies and a plurality of second heat exchange assemblies, which has a simple structure, reduces production difficulty and cost, and can adjust the size of the heat exchanger by adding or reducing the same number of first heat exchange assemblies and second heat exchange assemblies, so as to facilitate the formation of heat exchangers of different sizes according to user needs. Meanwhile, the first flow channel is formed by connecting a plurality of first heat exchange assemblies, and the second flow channel is formed by connecting a plurality of second heat exchange assemblies. The first flow channel and the second flow channel are independently formed, and the oil-water isolation and sealing effect is good.

[0009] In one of the embodiments, the included angle between the first heat exchange assembly and the second heat exchange assembly is 90°. The cross-laminating of the first heat exchange assembly and the second heat exchange assembly is facilitated, and interference between the first heat exchange assembly and the second heat exchange assembly is avoided.

[0010] In one of the embodiments, the first heat exchange assembly and the second heat exchange assembly have the same structure and each include two sets of laminates. One side of the laminate is provided with a recessed cavity, and both ends of the recessed cavity are provided with inlet and outlet holes penetrating in the thickness direction of the laminate. The two sets of laminates are connected by relative buckling to form the cavity with the two sets of recessed cavities, and the two sets of inlet and outlet holes form the through hole.

The flange in the first heat exchange assembly is arranged in the inlet and outlet hole in the adjacent first heat exchange assembly, and / or the flange in the second heat exchange assembly is arranged in the inlet and outlet hole in the adjacent second heat exchange assembly. When the plurality of first heat exchange assemblies and the plurality of second heat exchange assemblies are cross-laminated and combined, the flange and the inlet and outlet hole can play a positioning role, avoiding the relative misalignment of the two adjacent first heat exchange assemblies and / or the relative misalignment of the two adjacent second heat exchange assemblies, improving the combination accuracy, and ensuring the sealing requirement of subsequent welding connection.

[0012] In one of the embodiments, the two sets of flanges in the buckled two sets of laminates are diagonally arranged. The diagonal arrangement of the two sets of flanges can prevent deformation and stress concentration in the subsequent welding process, thereby ensuring the welding quality and part performance.

[0013] In one of the embodiments, a plurality of recessed ribs protruding towards the recessed cavity are arranged at intervals on the other side of the laminate. The recessed ribs can increase the heat exchange area of the cross-laminated first heat exchange assembly and second heat exchange assembly, thereby improving the heat exchange effect of the device. Meanwhile, the recessed ribs can improve the strength of the laminate, thereby improving the overall strength of the device.

[0014] In one of the embodiments, a mounting bracket is further included, the mounting bracket comprises end plates, the end plates are arranged at the left and right ends of the heat exchanger core, and the end plates can be mounted on the motorcycle.

By arranging the clamping positioning holes on the laminated sheets and the end plates, the laminated sheets and the end plates can be conveniently combined into the device by the external clamps and then welded as a whole, so that the welding efficiency is improved.

[0016] In one of the embodiments, among the upper and lower two groups of through holes at the left end of the heat exchanger core, one group of the through holes is connected with a water inlet pipe, and the other group of the through holes is sealingly connected with the end plate; among the upper and lower two groups of through holes at the right end of the heat exchanger core, one group of the through holes is connected with a water outlet pipe through a connecting head, and the other group of the through holes is sealingly connected with a plug; the water inlet pipe and the water outlet pipe are diagonally arranged; among the front and rear two groups of through holes at the left end of the heat exchanger core, one group of the through holes is connected with an oil outlet pipe through the connecting head, and the other group of the through holes is sealingly connected with the plug; among the front and rear two groups of through holes at the right end of the heat exchanger core, one group of the through holes is connected with an oil inlet pipe, and the other group of the through holes is sealingly connected with the end plate; the oil outlet pipe and the oil inlet pipe are diagonally arranged. By diagonally arranging the water inlet pipe and the water outlet pipe and diagonally arranging the oil outlet pipe and the oil inlet pipe, the stroke of the first flow channel and the second flow channel can be increased, and thus the heat exchange effect of the device is improved.

[0017] In one of the embodiments, abutting holes are arranged on the two groups of end plates, and one end of the two groups of plugs can be arranged in the abutting holes and connected with the side walls of the end plates.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] Please see Figure 1 and Figure 2 One embodiment of the cross-layered heat exchanger includes a heat exchanger core, which includes a first heat exchange component and a second heat exchange component. The first heat exchange component includes multiple arrayed first heat exchange assemblies, and the second heat exchange component includes multiple arrayed second heat exchange assemblies. Both the first and second heat exchange components have an internal cavity and two sets of through holes communicating with the cavity. The multiple sets of first heat exchange assemblies and the multiple sets of second heat exchange assemblies are cross-layered, such that the multiple sets of through holes at the upper and lower ends of the heat exchanger core are connected to form a first flow channel, and the multiple sets of through holes at the front and rear ends of the heat exchanger core are connected to form a second flow channel. The first heat exchange assemblies and the second heat exchange assemblies form an angle, so that the first and second flow channels are offset from each other in the axial direction.

[0031] In the above embodiments, the heat exchanger core is composed of multiple sets of first heat exchange components and multiple sets of second heat exchange components stacked in a cross-layered manner. Its composition structure is simple, reducing production difficulty and production cost. Moreover, the specifications of the heat exchanger can be adjusted by adding or removing the same number of first and second heat exchange components, making it convenient to assemble heat exchangers of different specifications according to user needs. At the same time, multiple sets of first heat exchange components are connected to form a first flow channel, and multiple sets of second heat exchange components are connected to form a second flow channel. The first and second flow channels are independently constructed, and their oil-water isolation and sealing effect is good.

[0032] Based on the above embodiment, the included angle between the first heat exchange component and the second heat exchange component is 90°. This facilitates the overlapping of the first and second heat exchange components and avoids interference between them.

[0033] Please see Figures 3 to 5 In one embodiment, the first heat exchange assembly and the second heat exchange assembly have the same structure, both including two sets of laminated plates 10. A cavity 101 is provided on one side of each laminated plate 10, and inlet / outlet holes 102 extending along the thickness direction of the laminated plate 10 are provided at both ends of each cavity 101. The two sets of laminated plates 10 are fastened together so that the two sets of cavityd plates 101 form a cavity, and the corresponding two sets of inlet / outlet holes 102 form a through hole. In the above embodiment, both the first heat exchange assembly and the second heat exchange assembly are composed of two sets of laminated plates 10 fastened together, resulting in a simple structure and further reducing production difficulty and cost.

[0034] Please see Figure 1 , Figure 4 and Figure 6 In one embodiment, a set of inlet / outlet holes 102 in the stacked laminations 10 are provided with flanges 1021 along their periphery. The flanges 1021 in the first heat exchange assembly pass through the inlet / outlet holes 102 in the adjacent first heat exchange assembly, and / or the flanges 1021 in the second heat exchange assembly pass through the inlet / outlet holes 102 in the adjacent second heat exchange assembly. In the above embodiment, when multiple sets of first heat exchange assemblies and multiple sets of second heat exchange assemblies are stacked in a cross-layered manner, the flanges 1021 and the inlet / outlet holes 102 can play a positioning role, avoiding relative misalignment between adjacent sets of first heat exchange assemblies and / or adjacent sets of second heat exchange assemblies during assembly, thus improving assembly accuracy. At the same time, the flanges 1021 passing through the inlet / outlet holes 102 can ensure the sealing requirements of subsequent welding connections.

[0035] Please see Figure 5 In one embodiment, in the two sets of overlapping pieces 10 that are fastened together, the two sets of flanges 1021 are arranged diagonally. In the above embodiment, the two sets of flanges 1021 are arranged diagonally to prevent deformation and stress concentration during subsequent welding, thereby ensuring welding quality and component performance.

[0036] Please see Figure 3 and Figure 4 In one embodiment, multiple sets of recessed ribs 104 protruding towards the cavity 101 are provided at intervals on the other side of the stacked plate 10. In the above embodiment, by providing the recessed ribs 104, the heat exchange area after the first heat exchange component and the second heat exchange component are cross-stacked can be increased, thereby improving the heat exchange effect of the device. At the same time, the recessed ribs 104 can increase the strength of the stacked plate 10, thereby improving the overall strength of the device.

[0037] Please see Figure 1 In one embodiment, the device further includes a mounting bracket, which includes end plates 30. End plates 30 are provided at both ends of the heat exchanger core, and the end plates 30 can be mounted on a motorcycle. The end plates 30 facilitate the mounting of the heat exchanger core on a motorcycle.

[0038] Please see Figures 1 to 3 In one embodiment, four sets of through-holes 103 for clamping are provided on both the laminate 10 and the end plate 30 along their thickness direction, and the four sets of clamping holes 103 are distributed in a square. In the above embodiment, by providing clamping holes 103 on the laminate 10 and the end plate 30, it is convenient to assemble all the laminates 10 and the end plate 30 into a device using external clamps and then perform overall welding, thereby improving welding efficiency.

[0039] Please see Figure 1 In one embodiment, in the two sets of through holes at the left end of the heat exchanger core, one set of through holes is connected to a water inlet pipe 20, and the other set of through holes is sealed to an end plate 30. In the two sets of through holes at the right end of the heat exchanger core, one set of through holes is connected to a water outlet pipe 202 through a connector 205, and the other set of through holes is sealed to a plug 201. The water inlet pipe 20 and the water outlet pipe 202 are arranged diagonally. In the two sets of through holes at the left end of the heat exchanger core, one set of through holes is connected to an oil outlet pipe 203 through a connector 205, and the other set of through holes is sealed to a plug 201. In the two sets of through holes at the right end of the heat exchanger core, one set of through holes is connected to an oil inlet pipe 204, and the other set of through holes is sealed to an end plate 30. The oil outlet pipe 203 and the oil inlet pipe 204 are arranged diagonally. In the above embodiments, by arranging the water inlet pipe 20 and the water outlet pipe 202 diagonally and the oil outlet pipe 203 and the oil inlet pipe 204 diagonally, the stroke of the first flow channel and the second flow channel can be increased, thereby improving the heat exchange effect of the device.

[0040] Based on the above embodiments, further, both sets of end plates 30 are provided with abutment holes 301, and one end of each set of plugs 201 can be inserted into the abutment hole 301 and connected to the side wall of the end plate 30. The cooperation between the abutment hole 301 and the plug 201 can increase the welding connection area between the end plate 30 and the heat exchanger core, thereby improving the stability of the connection between the end plate 30 and the heat exchanger core, and thus improving the overall stability of the device.

[0041] In this application, the heat exchanger core is composed of multiple sets of first heat exchange components and multiple sets of second heat exchange components stacked in a cross manner. Both the first and second heat exchange components are connected by two sets of laminations 10 that are snapped together. Its structure is simple, which reduces the difficulty and cost of production. Moreover, the specifications of the heat exchanger can be adjusted by adding or removing the same number of first and second heat exchange components, which makes it easy to assemble heat exchangers of different specifications according to user needs. At the same time, multiple sets of first heat exchange components are connected to form a first flow channel, and multiple sets of second heat exchange components are connected to form a second flow channel.
