DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0027] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply 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 understood as a limitation on the present invention.
[0028] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] like Figures 1 to 3 As shown, a radiator with an S-shaped flow channel inside includes a heat dissipation component, two cover plates 1 and two joint pipes 2. The heat dissipation component is arranged between the two cover plates and is composed of more than two heat dissipation fins 3 stacked and connected. Adjacent heat dissipation fins and heat dissipation fins and cover plates are connected by welding. Figures 4 to 7As shown, each heat sink is provided with a continuous S-shaped flow channel 4, and the two ends of the continuous S-shaped flow channel in every two adjacent heat sinks are connected to each other respectively. The two ends of one cover plate are respectively provided with an oil inlet hole 5 and an oil outlet hole 6 connected with the two ends of the continuous S-shaped flow channel of the adjacent heat sink, and two connecting pipes are respectively connected with the oil inlet hole and the oil outlet hole. The oil is input from the oil inlet hole, enters one end of the continuous S-shaped flow channel of each heat sink in turn, flows to the other end through the continuous S-shaped flow channel, and finally flows out through the oil outlet hole. Due to the special structural design of the flow channel, a bypass is formed, and at the same time, the flow path of the oil is extended, the heat dissipation area is increased, and the heat dissipation efficiency is effectively improved. The internal fins can be eliminated by adopting the utility model, and the production cost of the product is effectively reduced.
[0030] Combination Figures 4 to 6 As shown, the heat sink includes two sheets 301 with continuous S-shaped grooves 401 on one side. The two sheets have the same structure, one of which is rotated 180° along its plane and then snap-fitted with the other sheet to form a heat sink. The two continuous S-shaped grooves form a continuous S-shaped flow channel inside the heat sink, each continuous S-shaped flow channel is connected to the oil storage cavity provided at both ends inside the corresponding heat sink, and each oil storage cavity is composed of oil storage grooves 7 respectively provided on two corresponding sheets. The continuous S-shaped groove and the two oil storage grooves are formed by stamping the sheet from the inner side to the outer side, and a continuous S-shaped convex strip 8 and two protrusions 9 with through holes 901 are formed on the outer side of the sheet, and the two ends of the continuous S-shaped flow channel of each two adjacent heat sinks are connected through the oil storage cavity and the through hole, respectively, so as to ensure that the oil enters the interior of each heat sink from the oil inlet hole on one side of the product and finally flows out from the oil outlet hole on the other side.
[0031] In order to ensure the stability of the connection between adjacent heat sinks and between the heat sink and the cover plate, at least one welding block 10 is provided on the outer side of each heat sink, and the welding block is welded to the corresponding welding block on the adjacent heat sink. The number and position of the welding blocks match the number and position of the recessed parts of the continuous S-shaped convex strips, respectively. The height of the welding block is the same as the height of the convex block to ensure the stability of the welding structure. The cross-section of the welding block is a frustum-shaped structure, and the frustum-shaped table surfaces on two adjacent heat sinks are connected to improve the welding quality. The height of the welding block is greater than the height of the continuous S-shaped convex strips, and a gap is left between the continuous S-shaped convex strips on the outer sides of two adjacent heat sinks, which can further improve the heat dissipation efficiency of the oil in the continuous S-shaped flow channel.
[0032] The working principle of the utility model is as follows:
[0033] like Figures 1 to 7As shown, the utility model clamps the heat sinks 3 stacked one by one between two cover plates 1. The continuous S-shaped flow channel 4 inside each heat sink 3 is connected through the oil storage chamber and the through hole 901 located at both ends thereof, and is connected to the oil inlet hole 5 and the oil outlet hole 6 on one of the cover plates. The joint pipe 2 connected to the oil inlet hole 5 is the oil inlet pipe, and the joint pipe 2 connected to the oil outlet hole is the oil outlet pipe. During operation, the oil enters from the oil inlet pipe, and enters the oil storage chamber of each heat sink 3 through the oil inlet hole 5 in turn, passes through the corresponding continuous S-shaped flow channel 4, and flows from the oil storage chamber at the other end and its through hole 901 to the oil outlet hole 6, and finally flows out from the oil outlet pipe. The structural design of the continuous S-shaped flow channel forms a bypass flow due to the special structural design of the flow channel, while extending the oil flow path, increasing the heat dissipation area, and effectively improving the heat dissipation efficiency.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
