[0002] The car radiator is a major component of the water cooling system, which dissipates the heat in the coolant into the atmosphere. The core of the tube-and-fin radiator consists of many cooling tubes and fins. The cooling tubes are welded between the upper and lower water chambers to serve as channels for the cooling water, and the fins are fitted over the cooling tubes to increase the heat exchange area.

[0003] With the development of new energy vehicles and low-altitude aircraft, increasingly higher demands are being placed on the integration and size of heat dissipation modules. Due to the structural limitations of electric fans, reducing size is mainly achieved by improving the heat sink structure. Therefore, this invention proposes a novel circular tube-strip heat sink structure to further improve heat dissipation efficiency and reduce the size of the heat dissipation module.

[0029] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or prior art, the specific implementation of the utility model will be explained below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings and other implementation manners can be obtained without creative labor.

[0030] The utility model provides a kind of circular pipe belt type radiator of adopting elbow pipe structure, including spiral heat dissipation pipe and heat dissipation piece, heat dissipation piece is connected with spiral heat dissipation pipe.The technical scheme of the utility model is introduced in detail below with specific structure.

[0031] As Figures 1-2 As shown, spiral heat dissipation pipe includes heat dissipation pipe body 1, inlet joint 2 and outlet joint 3, heat dissipation pipe body 1 is formed by flat tube with center fold, and two sides flat tube is spirally formed with center fold point as center, or heat dissipation pipe body 1 is spirally formed by two parallel flat tubes and the spiral starting point of two parallel flat tubes is communicated, one end of heat dissipation pipe body 1 is communicated with inlet joint 2, and the other end of heat dissipation pipe body 1 is communicated with outlet joint 3.

[0032] It is easy to understand that the essence of heat dissipation pipe body 1 formed by spirally folding one flat tube and heat dissipation pipe body 1 formed by spirally forming two parallel flat tubes is the same, the difference lies in the different manufacturing process.

[0033] Since the flat tube is spirally formed by folding or the two flat tubes are spirally formed in parallel, the number of layers of heat dissipation pipe body 1 is even, the number of layers of heat dissipation pipe body 1 is related to the folded flat tube, preferably, the number of layers of heat dissipation pipe body 1 is greater than or equal to 12 layers, the number of layers of heat dissipation pipe can also be 16 layers, 20 layers, 24 layers, etc., the more the number of layers of heat dissipation pipe body 1, the relatively larger the overall volume of heat dissipation pipe body 1.

[0034] Further, by controlling the spacing of adjacent flat tubes, the overall volume of heat dissipation pipe body 1 can be adjusted, preferably, the spacing of adjacent flat tubes is 0.5-5cm, more preferably, the spacing of adjacent flat tubes is 1-3cm. It is easy to understand that in the case that the size and number of layers of flat tubes in heat dissipation pipe body 1 are the same, the larger the spacing of adjacent flat tubes, the larger the overall volume of heat dissipation pipe body 1, and correspondingly, the relative heat dissipation effect is improved.

[0035] In heat dissipation tube 1, the coolant flows in opposite directions in the two adjacent layers of flat tubes. Figure 1 Taking the perspective as an example, from the outside to the inside, the inlet connector 2 is located at the outermost layer, and the outlet connector 3 is located at the next outermost layer. The coolant flows in from the outermost flat tube, then into the third flat tube, then into the fifth flat tube, and so on. Finally, the coolant enters the spiral starting point, and then the coolant flows out along the other side of the flat tube. The coolant flowing out of each flat tube is always between the coolant flowing into the adjacent two flat tubes. That is, the characteristics of the heat dissipation tube 1 of this utility model itself realize that the coolant flows in opposite directions in the two adjacent flat tubes, and the coolant entering and exiting each layer of the heat dissipation tube 1 achieves counterflow, which greatly improves the heat exchange effect.

[0036] Both the inlet connector 2 and the outlet connector 3 are made of aluminum alloy and are formed by machining aluminum alloy round bars, which is conducive to the overall lightweighting of the spiral heat pipe. The inlet connector 2 and the outlet connector 3 are welded and fixed to both ends of the heat pipe body 1, respectively.

[0037] like Figures 1-2 As shown, the heat dissipation components are arranged between adjacent flat tubes inside the heat dissipation tube body 1, carrying away the heat of the coolant in the adjacent flat tubes.

[0038] In this invention, the heat sink can take various forms; any structure or electronic device that can achieve auxiliary heat dissipation is acceptable. Several feasible heat sink structures and arrangements are proposed below:

[0039] The heat sink can be in the form of conventional heat sink fins, such as... Figures 1-2 As shown, the heat dissipation fins 4 are arranged between adjacent flat tubes inside the heat dissipation tube body 1, and the heat dissipation fins 4 are welded and fixed to the sides of the two adjacent layers of flat tubes. It is easy to understand that the arrangement of the heat dissipation fins 4 does not affect the cooperation between the spiral heat dissipation tube and the electric fan; preferably... Figure 1 The heat dissipation fins 4 are arranged in a way that facilitates airflow through the spiral heat dissipation tube and carries away heat. Specifically, the heat dissipation fins 4 are arranged in the form of a sine wave, a rectangular wave or a sawtooth wave along the gap between adjacent flat tubes inside the heat dissipation tube body 1. The arrangement of the heat dissipation fins 4 in the figure is a sine wave.

[0040] Preferably, the heat dissipation fins 4 include one or both of the following: perforated fins and non-perforated fins. Perforated fins refer to fins with small through holes machined on them. These small through holes are arranged in a certain direction, either staggered or in a straight line.

[0041] More preferably, the heat dissipation fins 4 are formed by rolling double composite aluminum foil, which is beneficial to the overall lightweighting of the circular tube-strip heat sink. The heat dissipation fins 4 are brazed to the sides of the adjacent flat tubes to form a whole.

[0042] The heat dissipation member can also be a porous filling material, not shown in the drawings, which functions similarly to the heat dissipation fins 4, and the porous structure has a ventilation effect, facilitating cooperation with the electronic fan to carry away heat, wherein the porous filling material is preferably a metal material. The porous filling material is located between adjacent flat tubes, and the heat of the cooling liquid is transferred to the porous filling material, and under the action of the electronic fan, air flows out of the through holes of the porous filling material, carrying away the heat.

[0043] The heat dissipation member can also be an auxiliary heat dissipation pipe, not shown in the drawings, which is arranged along the adjacent flat tubes in the heat dissipation pipe body 1, and in the adjacent flat tubes, the flat tube in the direction of the inflow of the cooling liquid is attached to the auxiliary heat dissipation pipe, and there is a gap between the flat tube in the direction of the outflow of the cooling liquid and the auxiliary heat dissipation pipe, which functions as a ventilation effect, or in the adjacent flat tubes, the flat tube in the direction of the outflow of the cooling liquid is attached to the auxiliary heat dissipation pipe, and there is a gap between the flat tube in the direction of the inflow of the cooling liquid and the auxiliary heat dissipation pipe.

[0044] Specifically, one end of the auxiliary heat dissipation pipe is located at the spiral starting point of the heat dissipation pipe body 1, and the other end of the auxiliary heat dissipation pipe is located between the inlet joint 2 and the outlet joint 3, another kind of cooling liquid flows in the auxiliary heat dissipation pipe, and the flow direction of the cooling liquid in the auxiliary heat dissipation pipe is opposite to the flow direction of the cooling liquid in the attached flat tube.

[0045] It is easy to understand that the size of the auxiliary heat dissipation pipe is smaller than the size of the flat tube in the heat dissipation pipe body 1, and the auxiliary heat dissipation pipe functions to accelerate the heat dissipation of the cooling liquid in the flat tube attached thereto.

[0046] The circular pipe belt type radiator with the bent pipe structure has the advantages of low mold investment, short development cycle, strong pressure resistance, strong universality, smaller occupied assembly volume, etc., and the circular structure is easy to cooperate with the electronic fan, and the maximum heat exchange area is achieved under the projection area of the electronic fan, and the radiator module is easy to be integrated with the electronic fan.

[0047] The above embodiments provided by the present application are described in detail. In this paper, specific examples are applied to describe the principles and implementation methods of the present application, and the above embodiment description is only used to help understand the core idea of the present application. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principles of the present application, the present application can be improved and modified, and these improvements and modifications also fall within the protection scope of the claims of the present application.
