[0049] Traditional manifold structures are typically circular, with one end of multiple flat tubes installed perpendicular to the axis of the circular manifold. In this structure, when installing the water inlet and outlet pipes, a square interface is provided on the curved sidewall of the circular manifold away from the end of the flat tubes to prevent interference with the multiple flat tubes. This increases the installation area of ​​the circular manifold's water inlet and outlet pipes, allowing for the installation of larger diameter water inlet and outlet pipes. However, this structure creates a certain amount of resistance to the flow of cooling water, affecting the cooling effect. Furthermore, the square interface, after installation, increases the space occupied by the entire manifold, hindering the miniaturization of the air conditioner.

[0050] The present invention proposes a manifold 100 for solving the above problems.

[0051] See also Figures 1 to 2 In one embodiment of the present invention, the structure of the conventional manifold 100 is as follows: Figure 6 As shown, it is a circular structure, and one end of multiple flat tubes is installed perpendicular to the axis of the circular manifold. Figure 6In terms of the structure, if the flat tubes are to have a better cooling effect, their transverse width must be comparable to the diameter of the circular manifold, so that they can better guide the flow and effectively increase their own heat dissipation area. When the width of the flat tubes is close to the diameter of the circular manifold, when the water inlet and outlet pipes on the circular manifold are installed, in order to avoid interference with multiple flat tubes, the diameters of the water inlet and outlet pipes will be limited to a certain extent, which will affect the water inlet and outlet volume, thereby affecting the cooling effect. In order to solve the above problems, traditional circular manifolds are provided with a square interface on the arc-shaped side wall of the circular manifold away from the end of the flat tube, so as to increase the installation area of ​​the water inlet and outlet pipes of the circular manifold, thereby enabling the installation of water inlet and outlet pipes with larger diameters. However, this structure will have two problems: First, First, one end of the water inlet pipe and the water outlet pipe are not directly connected to the inner cavity of the circular manifold. During the flow of condensed water, the square interface creates a certain resistance to the flow of cooling water, resulting in a less than ideal water guiding effect. Second, the square interface will increase the circumferential space occupied by the entire circular manifold after installation, which is not conducive to the compact design of the entire manifold structure. Especially in the use environment of a heat sink, if the structure of the manifold can have a smaller space ratio while ensuring the heat dissipation effect, then it can effectively reduce the size of the entire air-conditioning structure and will be more friendly to other external mounting parts in terms of installation space.

[0052] Based on the above problems, in this embodiment, Figure 1 and Figure 3 As shown, the traditional circular manifold 100 structure is improved into a square main body structure. Specifically, the manifold 100 structure includes a square cylindrical hollow structure, and one side wall along its length direction is a mounting surface for mounting multiple heat dissipation flat tubes 6. Multiple side walls in the length direction corresponding to the mounting surface are set as conductive surfaces for mounting a connecting structure 2, and the connecting structure 2 is used to connect to an external water supply component. It should be noted here that the side surface on which the connecting structure 2 is generally mounted is one of the two side surfaces in the length direction adjacent to the mounting surface. Setting the manifold 100 as a square columnar structure has the following advantages: after multiple flat tubes are connected to the mounting surface, while ensuring that the width of the flat tubes is sufficient and a good heat dissipation effect can be achieved, the connection structure 2 can be directly installed on the two conductive surfaces adjacent to the mounting surface for water conduction. The connection structure 2 is directly connected to the inner cavity of the manifold body 1, and can achieve efficient water inlet and outlet effects. In addition, the connection structure 2 is directly installed on the side wall of the manifold body 1, which can effectively reduce the occupied space along the extension direction of the flat tubes, and the overall space occupancy rate is smaller, making the entire structure more compact.

[0053] Among them, such as Figure 1 and Figure 2 As shown, the manifold body 1 is provided with an assembled connection structure 2, and one end surface corresponding to the mounting surface is provided with a cover plate portion 12 structure, and the other recessed tube portion 11 is formed with a side opening corresponding to the cover plate portion 12, and the cover plate portion 12 is installed at the side opening to form a sealed conductive structure of the manifold body 1. In this embodiment, the manifold body 1 is provided with two relatively independent mounting structures. In the actual production process, both can be formed into corresponding structures by metal stamping, and then the two structures can be assembled and installed. This production method is more economical, and in order to further ensure the positioning and installation effect of the cover plate portion 12 at the side opening, a snap-fit ​​groove 121 is provided at the two long sides of the cover plate portion 12, and the two snap-fit ​​grooves 121 are respectively snapped with the two long side ends at the edge of the side opening to form a pre-installed fixing effect. In the subsequent sealing and fixing process, the positioning process can be simplified, making the actual production simpler. Of course, the one-piece molding method can also be applied to the manufacture of the manifold body 1 structure. Specifically, it can be selected according to actual conditions.

[0054] A plurality of mounting grooves (not shown) are provided on the cover portion 12. The plurality of mounting grooves are evenly spaced along the length direction of the cover portion 12, and the spacing between the plurality of mounting grooves is 6mm-12mm. The specific spacing is determined according to the actual heat dissipation requirements.

[0055] In this embodiment, in order to facilitate the installation of the cover portion 12 and the concave tube portion 11, a plurality of guide matching structures are provided between the concave tube portion 11 and the clamping groove 121. Figure 2 As shown, it specifically includes a plurality of sunken grooves 111 provided on the concave tube portion 11, and a plurality of protrusions 122 provided on the cover portion 12 corresponding to the plurality of sunken grooves 111. During installation, the protrusions 122 are guided and slid on the sunken grooves 111, which can ensure the corresponding size relationship between the installation of the cover portion 12 and the concave tube portion 11, so that it can ensure a good rectangular shape. In addition, the plurality of sunken grooves 111 can also increase the heat dissipation surface and improve its heat dissipation effect.

[0056] The connecting structure 2 is used to connect to the external water supply structure, which includes a water inlet 21 and a water outlet 22 or specifically includes one of them. The best choice for the corresponding conductive surface is the two long side walls adjacent to the installation surface (in some cases, it may be necessary to install the water inlet 21 and the water outlet 22 on a side wall opposite to the installation surface). When specifically set, one end of the water inlet 21 and the water outlet 22 are connected to the inner cavity of the manifold body 1. When the water inlet 21 and the water outlet 22 are both set on the manifold body 1, the water inlet 21 and the water outlet 22 are respectively set at the two end positions close to the manifold body 1. If it is a single-sided connecting structure 2, the connecting port can also be set in the middle position of the manifold body 1. It can be designed according to the actual flow and cooling requirements.

[0057] During use, the manifold body 1 needs to form a connection and fixing relationship with the external structure through the fixing structure 3. Generally, the fixing structure 3 will be set as a connecting ear, and it will be installed and fixed by bolts and other fixing structures 3. In addition, in order to ensure the sealing effect between the cover plate part 12 and the recessed tube part 11, welding can be used to form a fixed connection between the cover plate part 12 and the recessed tube part 11.

[0058] Among them, the side length of the square cross-section of the end of the manifold body 1 is generally set to between 30mm and 60mm, which includes the specific width of the mounting surface. The specific side length can be designed according to the actual heat dissipation flow demand, but is generally within the above range. Correspondingly, the width of the mounting groove is also set according to the side length. Generally, the single side is about 2mm smaller than the side length, and is generally set at 26mm≦L t ≦56mm.

[0059] This new invention also discloses a heat dissipation water tank 200, which includes the above-mentioned manifold 100. The specific structure of the manifold 100 is as described in the above-mentioned embodiments. Therefore, the heat dissipation water tank 200 includes the various beneficial effects exhibited by the above-mentioned manifold 100, which will not be described in detail here.

[0060] like Figure 3 and Figure 4 Specifically, the heat dissipation water tank 200 includes two manifolds 100, with their mounting surfaces facing each other. A plurality of heat dissipation flat tubes 6 are disposed between corresponding mounting slots on the two cover portions 12, forming a heat dissipation surface. To ensure the structural strength of the entire heat dissipation water tank 200, a reinforcing plate 5 is provided between the ends of the two corresponding manifold bodies 1 for connection and fixation, thereby increasing the strength of the entire heat dissipation water tank 200.

[0061] Among them, considering that the overall structure of the heat dissipation water tank 200 is affected by temperature, it will produce a certain thermal expansion and contraction effect, thereby causing its size to change within a small range. In this embodiment, Figure 3 and Figure 5 As shown, an expansion slot 51 is provided on the reinforcing plate 5, and the two ends of the expansion slot 51 are connected by a V-shaped structure 52. The expansion slot 51 can adapt to the deformation of the reinforcing plate 5 caused by thermal expansion and contraction, thereby improving the structural stability of the entire heat dissipation water tank 200.

[0062] The present invention also discloses a vehicle air conditioner, which includes a heat dissipation water tank 200. The heat dissipation water tank 200 has the structure as described in the above embodiment. Therefore, the vehicle air conditioner includes the various beneficial effects exhibited by the above heat dissipation water tank 200, which will not be described in detail here.

[0063] It should be noted that the use of the manifold 100 can effectively reduce the overall occupied space of the entire radiator water tank 200, which is beneficial to optimizing the occupied space of the entire air-conditioning structure. For other external structures, there will be more operating space. Especially for application scenarios with high space utilization such as automobiles, the manifold 100 in this solution has good application prospects.

[0064] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
