Description

Technical Field

[0001] This utility model relates to the field of flywheel housing technology, and more specifically, to a flywheel housing with a heat dissipation structure. Background Technology

[0002] The flywheel housing, as an important component of the engine system, protects the flywheel and clutch to ensure their stable operation. For example, patent publication number CN210344739U describes a flywheel housing for an automatic transmission, comprising: a flywheel housing, a flywheel, a first fixing block, a second fixing block, a third fixing block, a fourth fixing block, a first opening, a second opening, a third opening, a first through hole, a second through hole, and a protrusion. The flywheel is connected to the flywheel housing by bolts. The first fixing block is located on the left side of the outer wall end of the flywheel housing; the second fixing block is located on the right side of the outer wall end of the flywheel housing; the third fixing block is located on the right side of the bottom of the outer wall of the flywheel housing; the fourth fixing block is located on the lower left side of the outer wall of the flywheel housing; the first opening is located at the center of the right side of the outer wall of the flywheel housing, and the first opening penetrates the outer wall of the flywheel housing and extends into the interior of the flywheel housing.

[0003] However, existing flywheel housings mostly rely on adding external heat dissipation fins or opening ventilation holes for heat dissipation. While these passive cooling methods can increase the heat dissipation area of ​​the housing to some extent, their heat dissipation efficiency is limited in high-temperature or enclosed environments. This results in the continuous accumulation of heat generated by the friction between the flywheel and clutch inside the housing under high-power or long-term operation conditions. If this heat cannot be dissipated in a timely and effective manner, the housing temperature will rise, affecting its material properties and the normal operation of surrounding components. Therefore, we have made improvements and proposed a flywheel housing with a heat dissipation structure. An active cooling structure is set inside the flywheel housing in conjunction with an external cooling system to achieve active cooling of the flywheel housing. Utility Model Content

[0004] The main purpose of this utility model is to provide a flywheel housing with a heat dissipation structure, which can effectively solve the problem that existing flywheel housings usually use heat dissipation fins for passive heat dissipation, resulting in the inability to dissipate heat in a timely and effective manner under high power or long-term operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flywheel housing with a heat dissipation structure includes a main housing, the outer periphery of which is provided with reinforcing ribs, the outer surface of which is provided with a plurality of heat dissipation fins, and a heat exchange groove is provided inside the main housing, wherein a heat dissipation component for removing heat is installed inside the heat exchange groove.

[0007] Preferably, the heat exchange tank has an inlet at one end and an outlet at the other end.

[0008] Preferably, a one-way valve is fixedly installed at the outer end of the liquid inlet and the liquid outlet, and a connecting hose is connected to the outer end of each one-way valve.

[0009] Preferably, the heat dissipation assembly includes two heat exchange arc plates, which are joined by welding, and the heat exchange arc plates are connected to the heat exchange groove by welding.

[0010] Preferably, each heat exchange arc plate is provided with a mating seat on both sides, and the inner wall of the heat exchange groove is provided with a mating groove, and the mating seat and the mating groove are mutually restrictive and engaged.

[0011] Preferably, a flow groove is provided on the outer side of the heat exchange arc plate, a guide baffle is provided inside the flow groove, and a sealing plate is provided at both ends of the guide baffle. The guide baffle and the sealing plate are in close contact with the inner wall of the heat exchange groove.

[0012] The inlet and outlet are respectively connected to both ends of the flow tank.

[0013] Preferably, each of the two heat exchange arc plates has a mounting groove on both sides, and a sealing strip is provided inside the mounting groove. The heat exchange arc plate is sealed to the heat exchange groove through the sealing strip.

[0014] Preferably, the surface of the reinforcing rib is provided with several auxiliary grooves.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The two ends are connected to the one-way valves on both sides by connecting hoses at both ends, and the flow direction of the two one-way valves is the same. One end of the connecting hose is connected to the external cooling system, and the other end of the connecting hose is connected to the radiator of the external return cooling system. The cooling system circulates and delivers coolant, and the radiator of the return cooling system cools the coolant that has completed the heat exchange. This allows the coolant to circulate inside the heat exchange tank, thereby carrying away the heat inside the main body shell. The heat dissipation component can significantly improve the heat dissipation effect of this application compared to the existing flywheel shell, thereby effectively avoiding the degradation of material properties and the influence of surrounding components due to overheating, thereby improving the performance of the flywheel shell and ensuring the stability of subsequent drive.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 6 As shown, a flywheel housing with a heat dissipation structure includes a main housing 1, with reinforcing ribs 2 on the outer periphery of the main housing 1, and a plurality of heat dissipation fins 4 on the outer surface of the main housing 1. A heat exchange groove 5 is opened inside the main housing 1, and a heat dissipation component 6 for removing heat is installed inside the heat exchange groove 5.

[0026] The reinforcing rib 2 can reinforce the concave part of the heat exchange groove 5 to ensure the overall strength of the flywheel housing. Passive heat dissipation can be achieved through several heat dissipation fins 4. The heat generated inside the main housing 1 is discharged to the outside by the heat dissipation fins 4, which, together with the outside air, achieves auxiliary heat dissipation.

[0027] In this embodiment, a liquid inlet 9 is provided at one end of the heat exchange tank 5, and a liquid outlet 10 is provided at the other end of the heat exchange tank 5.

[0028] One-way valves 7 are fixedly installed on the outer ends of the liquid inlet 9 and the liquid outlet 10, and each one-way valve 7 is connected to a connecting hose 8 at its outer end. When the liquid inlet 9 and the liquid outlet 10 are interconnected with the heat exchange tank 5, the two ends of the connecting hose 8 are connected to the one-way valves 7 on both sides, and the flow direction of the two one-way valves 7 is the same. One end of the connecting hose 8 is connected to the external cooling system, and the other end of the connecting hose 8 is connected to the radiator of the external return cooling system. The cooling system circulates and delivers coolant, and the radiator of the return cooling system cools the coolant that has completed the heat exchange. This allows the coolant to circulate inside the heat exchange tank 5, thereby carrying away the heat inside the main body shell 1. Through the above structure, the heat dissipation effect of this application is significantly improved compared with the existing flywheel shell, thereby effectively avoiding the accumulation of heat inside the main body shell 1, and improving the performance of the flywheel shell to ensure the stability of subsequent drive.

[0029] In this embodiment, the heat dissipation assembly 6 includes two heat exchange arc plates 601, which are joined by welding. The heat exchange arc plates 601 are connected to the heat exchange groove 5 by welding.

[0030] In this embodiment, each heat exchange arc plate 601 is provided with a mating bracket 602 on both sides, and the inner wall of the heat exchange tank 5 is provided with a mating groove 501. The mating bracket 602 and the mating groove 501 are mutually restrictive and engaged. By using a thermally conductive material, the heat generated inside the heat exchange arc plate 601 can be exchanged with the coolant inside the flow tank 607, achieving a highly efficient heat dissipation effect. The mutually restrictive engagement of the mating bracket 602 and the mating groove 501 ensures that the two heat exchange arc plates 601 can be stably placed in the heat exchange tank 5 before welding, thereby ensuring the quality of the subsequent welding connection. High-precision machining is required during welding.

[0031] In this embodiment, a flow groove 607 is provided on the outer side of the heat exchange arc plate 601, a guide baffle 605 is provided inside the flow groove 607, and a sealing plate 606 is provided at both ends of the guide baffle 605. The guide baffle 605 and the sealing plate 606 are in close contact with the inner wall of the heat exchange groove 5.

[0032] The liquid inlet 9 and the liquid outlet 10 are respectively connected to the two ends of the flow tank 607.

[0033] The sealing plate 606 allows the flow channel 607 to be divided into a spiral channel by the guide baffle 605, so that the coolant can flow stably into it. The inlet 9 and outlet 10 are located on the side close to the sealing plate 606, so that the coolant can be stably transferred from the inlet 9 through the flow channel 607 to the outlet 10, and the coolant can cover the outer surface of the heat exchange arc plate 601, so as to achieve stable heat exchange of the heat exchange arc plate 601.

[0034] In this embodiment, mounting grooves 603 are respectively provided on both sides of the two heat exchange arc plates 601. Sealing strips 604 are installed inside the mounting grooves 603, and the heat exchange arc plates 601 are sealed to the heat exchange groove 5 through the sealing strips 604. The sealing strips 604, positioned between the heat exchange arc plates 601 and the heat exchange groove 5, prevent liquid leakage during heat exchange, thus ensuring stability during heat dissipation. The sealing strips 604 are made of heat-resistant material, and their sealing performance is ensured in conjunction with the heat dissipation of the coolant.

[0035] In this embodiment, the surface of the reinforcing rib 2 is provided with several auxiliary grooves 3. The use of several auxiliary grooves 3 can increase the surface area of ​​the reinforcing rib 2 and help improve its heat dissipation effect.

[0036] The working principle of this flywheel housing with a heat dissipation structure:

[0037] In use, one end needs to be connected to the external cooling system, and the other end needs to be connected to the radiator of the external cooling system via the hose 8 to achieve a closed loop of coolant circulation. Then, the coolant is circulated by starting the cooling system. During the circulation process, the coolant can dissipate heat from the internal heat through the heat exchange arc plate 601 using thermally conductive material, thus carrying away the current internal heat and achieving heat dissipation.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
