Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0036] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0037] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0039] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0040] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0041] Please refer to Figures 1 - 5 , this embodiment provides a runner plate 100, which includes a main board body 110 and a resin plate 120. The resin plate 120 is bonded to the main board body 110, and a heat exchange runner 103 is co-molded between the main board body 110 and the resin plate 120.

[0042] Please refer to Figures 1 - 5 , the working principle of the runner plate 100 is as follows:

[0043] The runner plate 100 connects the resin plate 120 and the main board body 110 by bonding, and is applied to a heat exchanger. This method does not require furnace brazing, which can reduce carbon emissions during the production process and will not leave flux residues in the runner, thus helping to improve the cleanliness of the product and avoid blockage of the runner.

[0044] It should also be noted that when bonding and connecting the resin plate 120 and the main board body 110, epoxy resin and other glues can be used as adhesives for glue sealing, so that it does not require furnace brazing, reduces carbon emissions generated by brazing during the production process, and there is no residual flux left in the runner of the manufactured product, which is helpful for and improves the cleanliness of the product;

[0045] In addition, in such a manner, based on the structural setting of the resin plate 120, compared with the existing metal plate body, the resin plate 120 is made of resin-based materials, has stronger forming ability, and can form more complex flow channels, greatly enhancing the heat exchange efficiency and thermal conductivity of the flow channel plate 100.

[0046] It should be noted that when the main plate body 110 is manufactured, it can be made of metal materials to improve its structural strength. Moreover, based on the structure of the resin plate 120, the complex flow channel structures inside it can be formed on the inner side surface of the resin plate 120. That is, the complex flow channel structures can be formed on the surface of the resin plate 120 where the heat exchange flow channel 103 is formed. Thus, the structural design of the main plate body 110 can be simplified, thereby improving its usage flexibility and reducing its manufacturing cost.

[0047] It can be understood that in this embodiment, the heat exchange flow channel 103 has an inlet 101 and an outlet 102, and both its inlet 101 pipe and outlet 102 pipe are connected to the main plate body 110. The flow direction of the heat exchange flow channel 103 can be adjusted according to actual requirements. In this embodiment, the heat exchange flow channel 103 is described as a U-shaped flow channel. That is, the head end and the tail end of the heat exchange flow channel 103 are located on the same side of the flow channel plate 100.

[0048] Furthermore, based on the above content, please refer to Figures 1 - 7 , in this embodiment, when configuring the resin plate 120, to improve its usage flexibility, the resin plate 120 can include multiple sub-plate bodies 121. The multiple sub-plate bodies 121 are arranged in an array, and each sub-plate body 121 jointly forms a sub-flow channel 104 with the corresponding area of the main plate body 110. Among them, the multiple sub-flow channels 104 are sequentially connected to form the heat exchange flow channel 103.

[0049] That is, the resin plate 120 can be assembled in a split manner. Such a manner is conducive to reducing its manufacturing cost and is also conducive to later maintenance and installation. In addition, it is also conducive to forming more complex and diverse flow channel structures.

[0050] And in such a manner, the heat exchange flow channel 103 is divided into multiple segments along its extending direction. The extending direction of the heat exchange flow channel 103 is as shown by the arrow in Figure 3 . Each segment of the heat exchange flow channel 103 corresponds to a sub-flow channel 104. That is, the multiple sub-flow channels 104 are sequentially connected to form the heat exchange flow channel 103.

[0051] Please refer to Figures 1 - 12, and on the basis of being configured with multiple sub - plate bodies 121, in order to connect multiple sub - flow channels 104 in sequence along the extending direction of the heat - exchange flow channel 103. Therefore, along the extending direction of the heat - exchange flow channel 103, a plurality of diversion grooves 122 are arranged on the side surfaces of adjacent sub - plate bodies 121 that are in contact with each other, and the diversion grooves 122 connect the adjacent sub - flow channels 104. It should be noted that the diversion grooves 122 are arranged on the side surfaces of each sub - plate body 121 that are in contact with the adjacent sub - plate bodies 121, and are opened along the extending direction of the heat - exchange flow channel 103, and the openings of the diversion grooves 122 face the main plate body 110. The purpose is to be able to connect the adjacent sub - flow channels 104 after each sub - plate body 121 is docked with the main plate body 110.

[0052] In this way, the structure of the flow - channel plate 100 can be simplified, and the diversion grooves 122 can be integrally formed with each sub - plate body 121, so that the structural setting can be simplified. Thus, after each sub - plate body 121 is bonded to the main plate body 110, the corresponding sub - flow channels 104 can be formed, and at the same time, the sub - flow channels 104 can be conducted in the preset flow direction, so that the structural setting method can be simplified and the manufacturing cost can be reduced.

[0053] Furthermore, in this embodiment, as can be known from the foregoing content, the resin plate 120 provided in this embodiment is made of resin material. Based on this, complex and diverse flow - channel structures can be formed, that is, the flow direction and related styles of the heat - exchange flow channel 103 can be set according to actual needs. In this embodiment, one of the flow - channel styles is taken as an example for illustration;

[0054] Please refer to Figures 1 - 13 , when installing multiple sub - plate bodies 121, in order to improve the installation stability. Therefore, on the basis of bonding the sub - plate body 121 to the main plate body 110, adjacent two sub - plate bodies 121 can be bonded, and a clamping structure can also be arranged at the connection of adjacent two sub - plate bodies 121 to improve the connection stability and sealing performance in this way;

[0055] When configuring the clamping structure, there are various setting methods. In this embodiment, along the extending direction of the heat - exchange flow channel 103, a first clamping portion 123 and a second clamping portion 124 are respectively arranged on one side of adjacent two sub - plate bodies 121 that are in contact with each other, and the first clamping portion 123 is engaged with the second clamping portion 124. That is, when configuring the above - mentioned clamping structure, the multiple sub - plate bodies 121 are clamped and connected in sequence along the extending direction of the heat - exchange flow channel 103.

[0056] Moreover, when configuring the above-mentioned first clamping portion 123 and second clamping portion 124, in order to improve their sealing performance, the first clamping portion 123 may include a clamping groove 125 arranged along the contour of the diversion groove 122, and the second clamping portion 124 may include a clamping platform 126 arranged along the contour of the diversion groove 122. The clamping groove 125 is used for plugging and cooperating with the clamping groove 125. It should be noted that from the above content, it can be seen that in this embodiment, a diversion groove 122 is arranged on the side surface of the sub-plate body 121 to connect two adjacent sub-channels 104. Based on this, along the extending direction of the heat exchange channel 103, clamping grooves 125 are formed on the corresponding side surfaces of two adjacent sub-plate bodies 121. Thus, one of the adjacent and correspondingly cooperating first clamping portion 123 and second clamping portion 124 is a clamping groove 125, and the other is a clamping platform 126, and both are arranged around the contour of the diversion groove 122. Furthermore, the clamping groove 125 can be plugged and cooperated with the clamping platform 126 and is adapted to the structure of the aforementioned diversion groove 122, so as to improve the connection stability and sealing performance at the same time.

[0057] Furthermore, please refer to Figures 1 - 13 , in this embodiment, in order to guide the fluid in the heat exchange channel 103 to flow from its inlet 101 to its outlet 102 direction, therefore, a corresponding diversion structure is arranged in each sub-channel 104. Among them, the diversion structure can be arranged on the inner side surface of the sub-plate body 121 or on the inner side surface of the main plate body 110; specifically, in this embodiment, a plurality of first diversion platforms 127 are arranged on the side surface of each sub-plate body 121 where the sub-channel 104 is formed, that is, a plurality of first diversion platforms 127 are arranged on the inner side surface of the sub-plate body 121;

[0058] Moreover, the plurality of first diversion platforms 127 are arranged in multiple columns, and each column of first diversion platforms 127 is arranged along the extending direction of the heat exchange channel 103; among them, the first diversion platform 127 is used to guide the fluid in the heat exchange channel 103 to flow from the inlet 101 of the heat exchange channel 103 to its outlet 102.

[0059] Furthermore, through the arrangement of the above-mentioned first diversion platform 127, the flow of the fluid in the sub-channel 104 can be guided. And the first diversion platform 127 includes a first diversion block 128 and a second diversion block 129. The first diversion block 128 and the second diversion block 129 are connected at an angle, and along the direction from the inlet 101 to the outlet 102 of the heat exchange channel 103, the distance between the first diversion block 128 and the second diversion block 129 gradually increases. Thus, the first diversion platform 127 is in a V-shaped or Y-shaped structural pattern, and further can avoid its backflow.

[0060] Based on the above-mentioned first flow guiding platform 127, corresponding structures can also be provided on the inner side of the main board body 110. That is, a plurality of second flow guiding platforms 111 are arranged in an array on the main board body 110. The plurality of second flow guiding platforms 111 are arranged in multiple columns, and each column of second flow guiding platforms 111 is arranged along the extending direction of the heat exchange flow channel 103;

[0061] In addition, to reduce the thickness of the flow channel plate 100, therefore, the multiple columns of first flow guiding platforms 127 and the multiple columns of second flow guiding platforms 111 can be arranged out of order. That is, the arrangement direction of the first flow guiding platforms 127 is the same as that of the second flow guiding platforms 111, but they are arranged out of order, so that one second flow guiding platform 111 is distributed between two adjacent first flow guiding platforms 127.

[0062] Furthermore, based on the structures of the above-mentioned first flow guiding platform 127 and second flow guiding platform 111, to improve the structural strength of the flow channel plate 100, therefore, a plurality of abutting platforms 131 are arranged between each column of first flow guiding platforms 127, and the plurality of abutting platforms 131 all abut against one column of second flow guiding platforms 111 correspondingly. In this way, it can not only play a role in guiding the flow, but also increase the strength of the flow channel plate 100. In addition, similarly, the abutting platforms 131 can also be arranged on the inner side of the main board body 110 and located between two adjacent second flow guiding platforms 111, and they are used to abut against the first flow guiding platforms 127.

[0063] In addition to the above structures, to improve the connection stability between the resin plate 120 and the main board body 110, a plurality of riveting grooves can also be provided on the outer edge of each sub-board body 121, and a plurality of riveting holes are provided on the outer edge of the main board body 110. Thus, in this way, while the flow channel plate 100 is connected based on the above structures, it can also be riveted by the riveting grooves and riveting holes at multiple places on its outer edge, thereby improving its connection stability.

[0064] It should also be noted that in this embodiment, the heat exchange flow channel 103 is set as a U-shaped flow channel for illustration. Based on the above structures, it can also be set as an I-shaped flow channel or an L-shaped flow channel, etc. And the structure of its internal flow channel can be adjusted according to actual needs. That is, based on the structure of the resin plate 120, its forming ability is stronger, and it can form more complex flow channels. The internal flow channel structure can be flexibly designed, greatly enhancing the heat exchange efficiency and heat conductivity of the heat exchanger.

[0065] Based on the above content, please refer to Figures 1 - 13This embodiment also provides a heat exchanger, which includes at least one of the above-mentioned flow channel plates 100. The heat exchanger uses a bonding method to connect the resin plate 120 to the main body 110 in the flow channel plate 100, so that there is no need to braze in the furnace when making the flow channel plate 100, which can reduce carbon emissions during the production process and will not leave residual flux in the flow channel, thereby helping to improve the cleanliness of the product and avoid blockage in the flow channel. It should also be noted that in this way, based on the structural setting of the resin plate 120, compared with the existing metal plate body, the resin plate 120 is made of resin material, which has a stronger forming ability and can form a more complex flow channel, greatly enhancing the heat exchange efficiency and thermal conductivity of the heat exchanger.

[0066] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
