Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to an end porous tube reinforced radiating core. Background Art

[0002] The heat sink is the core component of the radiator. The structural strength of the heat sink is directly related to the normal operation of the automobile engine. The heat sink has main plates at the upper and lower ends, and multiple heat pipes are connected between the two main plates. During operation, due to thermal expansion and contraction, the heat pipes and the main plates are prone to breakage, which in turn causes radiator leakage and affects the normal operation of the engine.

[0003] After disassembling and analyzing the old radiators returned from the aftermarket, it was found that most radiators failed because the strength of the joint between the end of the radiator core main plate and the heat pipe was not high, and they were easily broken after being impacted during operation of the vehicle. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a heat dissipation core with reinforced end multi-hole tubes.

[0005] The utility model is realized through the following technical scheme, providing an end porous tube reinforced heat dissipation core, comprising a main plate, porous tube areas are arranged at both ends of the main plate, a single-hole tube area is arranged between the two porous tube areas, a plurality of porous tubes arranged along the length direction of the main plate are connected to the main plate of the porous tube area, a plurality of single-hole tubes arranged along the length direction of the main plate are connected to the main plate of the single-hole tube area, the single-hole tube comprises a flat single-hole tube body, the porous tube comprises a flat porous tube body and a plurality of partitions fixed in the porous tube body, and the plurality of partitions divide the porous tube body into a plurality of tube cavities.

[0006] In this solution, porous tubes are used in the porous tube areas at both ends of the main plate. The multiple partitions in the porous tubes can improve the strength of the entire porous tube, thereby improving the strength of the entire radiator core at the end position of the main plate to prevent breakage after impact.

[0007] As an optimization, a pipe clamp is connected between two adjacent single-hole pipes at the end of the single-hole pipe area, and the pipe clamp includes a clamping plate, and plugging plates inserted into the two adjacent single-hole pipes are respectively fixed on both sides of the clamping plate. In this solution, a pipe clamp is connected between two adjacent single-hole pipes at the end of the single-hole pipe area, so that the two adjacent single-hole pipes at the end of the single-hole pipe area are connected as a whole, thereby improving the connection strength at this position.

[0008] As an optimization, two plug-in plates are fixedly connected to each of the two ends of the clamping plate. In this solution, two plug-in plates are arranged at each of the two ends of the clamping plate, so a total of four plug-in plates are inserted into the single-hole pipe to improve the connection strength.

[0009] As an optimization, the wall thickness of the multi-hole tube body is greater than that of the single-hole tube body, thereby improving the strength of the four corners of the radiator core.

[0010] As an optimization, two opposite tube walls of the single-hole tube body are provided with convex strips protruding toward opposite sides. The convex strips in this solution improve the strength of the single-hole tube.

[0011] As an optimization, the porous tube area is provided with two rows of porous tubes, and the single-hole tube area is provided with two rows of single-hole tubes. In this solution, two rows of porous tubes and single-hole tubes are provided, so that the strength of the entire radiator core can be further improved.

[0012] The beneficial effects of the utility model are as follows: the utility model provides an end porous tube reinforced heat dissipation core, which replaces the heat dissipation tubes at the ends with porous tubes with higher strength and thicker heat dissipation tube material, thereby greatly improving the strength of the four corner ends of the heat dissipation tube and improving the strength and service life of the heat dissipation core.

[0025] A porous tube area is provided at both ends of the main sheet 1, and a single-hole tube area is provided between the two porous tube areas. The main sheet 1 in the porous tube area is connected to a plurality of porous tubes 2 arranged along the length direction of the main sheet 1, and the upper and lower ends of the porous tubes 2 pass through the upper and lower main sheets 1 respectively. The main sheet 1 in the single-hole tube area is connected to a plurality of single-hole tubes 3 arranged along the length direction of the main sheet 1, and the upper and lower ends of the single-hole tubes 3 pass through the upper and lower main sheets 1 respectively. The porous tubes 2 and the single-hole tubes 3 are arranged side by side.

[0026] The main sheet is provided with main sheet holes, so that the porous tube 2 and the single-hole tube 3 can pass through, and are brazed at the passing points. The number of porous tubes is determined according to the number of main sheet holes. When the main sheet 1 is longer, more porous tubes 2 can be added, and when the main sheet 1 is shorter, fewer porous tubes 2 can be added. The number of porous tubes ranges from 2 to 5.

[0027] like Figure 3 As shown, the porous tube 2 includes a flat porous tube body 24 and a plurality of partitions 22 fixed in the porous tube body 24, and the plurality of partitions 22 divide the porous tube body 24 into a plurality of tube cavities. The cross section of the porous tube body 24 is long and the length direction extends along the width direction of the main sheet 1. The porous tube body 24 is provided with two parallel tube walls, and the two tube walls are connected to form the porous tube body 24. The partition 22 connects the two tube walls, thereby dividing the porous tube body 24 into a plurality of tube cavities.

[0028] The single-hole tube 3 includes a flat single-hole tube body 31, and the wall thickness of the multi-hole tube body 24 is greater than the wall thickness of the single-hole tube body 31. The cross section of the single-hole tube body 31 is long and the length direction extends along the width direction of the main sheet 1. The single-hole tube body 31 is provided with two parallel tube walls, and the two opposite tube walls of the single-hole tube body 31 are provided with convex strips 32 protruding to the opposite side, and the corresponding convex strips 32 on the two tube walls are connected.

[0029] like Figure 1 As shown, a pipe clamp 4 is connected between two adjacent single-hole pipes 3 at the end of the single-hole pipe area. Figure 5 As shown, the pipe clamp 4 includes a clamping plate 41, which is located between two adjacent single-hole pipes 3 and parallel to the end surface of the single-hole pipe 3. Both sides of the clamping plate 41 are respectively fixed with plugging plates 42 inserted into the two adjacent single-hole pipes 3. The plugging plates 42 are perpendicular to the clamping plate 41. In this embodiment, two plugging plates 42 are fixed at each end of the clamping plate 41.
