[0002] At present, the conventional combined parallel flow condenser and fuel oil radiator on the market, the manifold at the condenser end and the manifold at the fuel oil radiator end are two independent tubes, the media in the two manifolds are different, the two media circulate in their respective channels and dissipate heat independently, and the two tubes are connected by a connecting joint. The disadvantages of this structure are: 1) The connection operation steps of the two tubes are cumbersome. When connecting, the manifold needs to be expanded first, and then the welding ring and the connector are manually assembled, and then connected to the manifolds on both sides, and finally fixed by spot welding; 2) In order to avoid the position of the connecting joint, non-standard flat tubes need to be used, which is time-consuming, labor-intensive and error-prone to assemble; 3) The manifolds connected together by spot welding are prone to poor concentricity, which is not conducive to subsequent assembly and may even cause poor brazing.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the utility model is a combined parallel flow condenser and fuel oil radiator, which mainly includes a radiator 3 (specifically a fuel oil radiator), a condenser (specifically a parallel flow condenser), and a header. The radiator 3 and the condenser are installed in combination as a combined radiator body. The headers are fixedly installed on both sides of the radiator 3. The condenser includes a condenser end header 5. The radiator 3 includes a fuel oil radiator end header 4. The condenser end header 5 and the fuel oil radiator end header 4 together constitute the header, and a mounting bracket 7 is provided on the side of the header.

[0025] like Figure 2-3 As shown, the manifold in the utility model adopts an integrated tube structure, in which a flat partition 6 is provided, and the integrated tube structure is divided into a condenser end manifold 5 and a fuel oil distribution end manifold 4 by the partition 6, that is, the condenser end manifold 5 and the fuel oil distribution end manifold 4 are an integrated tube structure. Specifically, the partition 6 is provided at Figure 1 The position near the upper end makes the length of the condenser end collecting pipe 5 greater than the length of the fuel oil distribution end collecting pipe 4; preferably, two partitions are arranged, and the two partitions have the same structure and are arranged in parallel along the axial direction of the integrated tube structure; a leakage observation hole 9 can also be provided on the side wall of the integrated tube structure between the two partitions, so as to timely detect the poor sealing of the partition.

[0026] like Figure 1 As shown, in the utility model, an integrated manifold is arranged on both sides of the radiator 3, wherein the fuel distributing end manifold 4 of the left integrated manifold is connected to the oil inlet 1, and the fuel distributing end manifold 4 of the right integrated manifold is connected to the oil outlet 2.

[0027] Compared with the current collecting tube in the existing combined radiator (such as Figure 4 As shown), the utility model does not need to connect the condenser end header 5 and the fuel dispersing end header 4, thus avoiding the prior art due to expansion of the pipe, welding ring installation, connection joint 8 ( Figure 5) installation and the like, and the cumbersome operation steps, etc., reduce the installation difficulty and the manufacturing cost of the entire product. In addition, the coaxiality of the two headers in the utility model is high, making the assembly of the core more efficient.

[0028] like Figure 6 As shown, the partition 6 in the utility model includes a partition body and a design of the outer shape of the partition body. The outer shape of the partition body specifically includes a side limit convex edge 6-3 and a top limit convex edge 6-6 protruding outward along the partition. One side of the two side limit convex edges 6-3 is transitioned to mutually connected straight side edges 6-2 through rounded corners, and the other side of the two side limit convex edges 6-3 is transitioned to arc-shaped side edges 6-4 bent toward each other through first bends 6-1, and the two arc-shaped side edges 6-4 are connected to the top limit convex edge 6-6 through second bends 6-5. During installation, the side limit convex edges 6-3 are installed on both sides of the manifold close to the fuel radiator, and the top limit convex edge 6-6 is set on the side of the manifold away from the fuel radiator. The thickness of the partition 6 is preferably 3mm.

[0029] like Figure 7 As shown, it can be seen from the installation structure of the partition in the utility model that since the partition 6 in the utility model adopts a plate-like structure, compared with the complex structure of the connecting joint 8 in the prior art ( Figure 5 ), there is no need to do avoidance during the installation process, and multiple flat tubes arranged in parallel can adopt a unified size, avoiding the problem of reducing production line efficiency and comprehensive cost due to the introduction of non-standard flat tubes.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
