Description

Technical Field

[0001] This utility model relates to the field of cylinder head technology, and more specifically, to a cylinder head with a cooling structure. Background Technology

[0002] The cylinder head is a core pressure-bearing and heat-dissipating component of power equipment such as internal combustion engines and compressors. It comes into direct contact with high-temperature combustion gases or high-pressure media and continuously generates a large amount of heat during equipment operation. The operating temperature of the cylinder head directly affects the thermal efficiency, power performance, and operational safety of the equipment. If it cannot be cooled in time, the cylinder head temperature will be too high, causing valve seat deformation, gasket failure, spark plug carbon buildup, and other malfunctions. In severe cases, it may even cause the cylinder head to crack, shortening the service life of the equipment. Therefore, the design of the cylinder head cooling structure is a key link to ensure the stable operation of the equipment.

[0003] In the prior art, patent CN222501868U discloses an engine block and cylinder head cooling structure assembly, including a coolant tank, a heat dissipation component on one side of the coolant tank, an auxiliary component installed on one side of the coolant tank and the heat dissipation component, a conveying component on the coolant tank, and a fixing component on the conveying component. The auxiliary component on the coolant tank and the heat dissipation component can clean impurities adhering to different heat dissipation locations on the heat dissipation component, which is beneficial for better cooling of the engine block and cylinder head. Simultaneously, the fixing component on the conveying component not only installs and fixes the pipes that convey coolant to the engine block and cylinder head cooling structure assembly, improving the stability of the coolant conveying pipes, but also allows for auxiliary adjustment based on the placement of the coolant conveying pipes. Furthermore, the heat dissipation component on the coolant tank facilitates auxiliary heat dissipation for the engine block and cylinder head.

[0004] Existing cylinder head water-cooling structures typically employ the method of directly casting water channels or installing cooling pipes inside the cylinder head body. If the above solutions use cooling pipes, it is necessary to fix the internal cooling pipes and external components such as water tanks and water pumps separately. The installation and subsequent maintenance steps are cumbersome and difficult. Furthermore, the contact area between the cooling pipes and the heat source is small, resulting in poor cooling effect. Long-term use of the cooling water channels can lead to scale buildup on the inner walls, blockage of the water channels, and reduced cooling effect. Utility Model Content

[0005] The main objective of this invention is to provide a cylinder head with a cooling structure, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cylinder head with a cooling structure includes a cylinder head body, a cover plate fixedly connected to the surface of the cylinder head body, a cooling mechanism provided on the cover plate, the cooling mechanism including a cooling water tank and a water storage tank, a cooling groove provided on the upper surface of the cylinder head body, the cooling water tank installed in the cooling groove, and a fixing mechanism provided at both ends of the cooling water tank.

[0008] Preferably, the water storage tank is fixedly installed on the cover plate, and a water pump and a cooling plate are installed inside the water storage tank. An inlet pipe and an outlet pipe are fixedly connected to both ends of the water storage tank, and the output end of the water pump is fixedly connected to the inlet pipe.

[0009] Preferably, the ends of the inlet pipe and outlet pipe furthest from the water storage tank are connected to the mounting pipe via sealing joints, and the mounting pipe is connected to the cooling water tank.

[0010] Preferably, the cooling water tank is hollow and has a heat dissipation channel arranged laterally in the middle.

[0011] Preferably, mounting grooves are provided on both sides of the cylinder head body, and the positions of the mounting grooves are adapted to the positions of the mounting pipes.

[0012] Preferably, the fixing mechanism includes an I-beam sleeve, which is fixedly sleeved on the mounting pipe, and the I-beam sleeve is snapped into the mounting groove, with its two side walls respectively having an interference fit with the two sides of the cylinder head body.

[0013] Preferably, a fixing block is fixedly connected to one end of the I-beam sleeve located on the outer side of the cylinder head body. One side of the fixing block is in contact with the outer wall of the cylinder head body, and a guide block is fixedly connected to the other side. An insert block is slidably inserted into the guide block. A spring is fixedly connected between the insert block and the inner wall of the guide block. A pull rod is sleeved inside the spring. One end of the pull rod is fixedly connected to the insert block, and the other end slides through the guide block.

[0014] Preferably, a limiting seat is provided on one side of the fixing block, the limiting seat is fixedly installed on the cover plate, and one end of the insert block is inserted into the fixing block and the limiting seat.

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

[0016] (1) The water in the storage tank is cooled by the cooling plate and the cooling water is sent into the inlet pipe by the water pump. The water is then transported to the cooling water tank through the inlet pipe. The horizontal heat dissipation channel in the middle of the cooling water tank increases the contact area between the cooling water and the heat, thus enhancing the cooling effect. After absorbing the heat, the cooling water flows back to the storage tank through the outlet pipe, forming a circulating cooling loop. By opening a cooling groove on the upper surface of the cylinder head body and installing the cooling water tank in the cooling groove, the cooling water tank can be directly close to the heat source area of ​​the cylinder head body, and the contact area with the heat source area is increased, thus improving the cooling effect.

[0017] (2) By adopting the interference fit between the I-shaped tube sleeve and the cylinder head body on both sides and the double fixing method of locking the plug and the limit seat, the fixing strength of the cool water tank is greatly improved, avoiding the cylinder head vibration causing the connection between the cool water tank and the pipe to loosen and leak, ensuring the sealing of the cooling circuit. The spring-driven plug structure makes the disassembly and assembly of the cool water tank easier. After the cover plate is fixed, there is no need to use tools and fasteners to fix the cool water tank, reducing the difficulty and cost of water circuit disassembly during later maintenance.

[0026] 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.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown in the figure, this utility model embodiment proposes a cylinder head with a cooling structure, including a cylinder head body 1, a cover plate 4 fixedly connected to the surface of the cylinder head body 1, a cooling mechanism 3 provided on the cover plate 4, the cooling mechanism 3 including a cooling water tank 37 and a water storage tank 31, a cooling groove 101 provided on the upper surface of the cylinder head body 1, the cooling water tank 37 installed in the cooling groove 101, and a fixing mechanism 2 provided at both ends of the cooling water tank 37.

[0028] like Figures 1-7 As shown, the water storage tank 31 is fixedly installed on the cover plate 4. The water storage tank 31 is equipped with a water pump 35 and a cooling plate 36. The two ends of the water storage tank 31 are respectively fixedly connected to the water inlet pipe 32 and the water outlet pipe 33. The output end of the water pump 35 is fixedly connected to the water inlet pipe 32. The ends of the water inlet pipe 32 and the water outlet pipe 33 away from the water storage tank 31 are respectively connected to the mounting pipe 38 through the sealing joint 34. The mounting pipe 38 is connected to the cooling water tank 37. The cooling water tank 37 is hollow and has a heat dissipation channel 371 arranged horizontally in the middle. The cylinder head body 1 has mounting grooves 102 on both sides. The position of the mounting grooves 102 is adapted to the position of the mounting pipe 38.

[0029] In this application, the inlet pipe 32 and the outlet pipe 33 are flexible pipes, and the mounting pipe 38 is a rigid pipe. A cooling groove 101 is opened on the upper surface of the cylinder head body 1, and the cooling water tank 37 is installed in the cooling groove 101, so that the cooling water tank 37 can directly contact the heat source area of ​​the cylinder head body 1, and the contact area with the heat source area is increased, thereby improving the cooling effect.

[0030] During operation, the water in the water storage tank 31 is cooled by the cooling plate 36, and the cooling water is sent to the water inlet pipe 32 by the water pump 35. The water inlet pipe 32 is then transported to the cooling water tank 37. The horizontal heat dissipation channel 371 in the middle of the cooling water tank 37 increases the contact area between the cooling water and the heat, thus enhancing the cooling effect. After absorbing heat, the cooling water flows back to the water storage tank 31 through the water outlet pipe 33, forming a circulating cooling circuit. The mounting grooves 102 on both sides of the cylinder head body 1 provide positioning and installation space for the mounting pipe 38.

[0031] like Figure 1 , Figure 5 , Figure 6As shown, the fixing mechanism 2 includes an I-beam sleeve 21, which is fixedly sleeved on the mounting tube 38 and snapped into the mounting groove 102. The two side walls are respectively interference-fitted with the two sides of the cylinder head body 1. A fixing block 22 is fixedly connected to one end of the I-beam sleeve 21 located on the outside of the cylinder head body 1. One side of the fixing block 22 is in contact with the outer wall of the cylinder head body 1, and a guide block 23 is fixedly connected to the other side. An insert block 26 is slidably inserted into the guide block 23. A spring 25 is fixedly connected between the insert block 26 and the inner side wall of the guide block 23. A pull rod 24 is sleeved inside the spring 25. One end of the pull rod 24 is fixedly connected to the insert block 26, and the other end slides through the guide block 23. A limit seat 27 is provided on one side of the fixing block 22. The limit seat 27 is fixedly installed on the cover plate 4. One end of the insert block 26 is inserted into the fixing block 22 and the limit seat 27.

[0032] The cooling water tank 37 is fixedly installed in the cooling tank 101 through the mounting pipes 38 at both ends. The I-shaped sleeves 21 fitted on the two mounting pipes 38 are inserted into the mounting groove 102 to fix the left and right positions of the cooling water tank 37. Then, the pull rod 24 is pulled outward to move the insert 26 outward and install the cover plate 4 on the cylinder head body 1 with fasteners so that the position of the limit seat 27 corresponds to the position of the insert 26. Then, the pull rod 24 is slowly returned so that the insert 26 passes through the fixing block 22 and is inserted into the limit seat 27 to fix the up and down positions of the cooling water tank 37. Thus, the cooling water tank 37 is firmly fixed in the cooling tank 101. The fixing block 22 is attached to the outside of the cylinder head body 1. After its position is fixed, it can also prevent dust and debris from entering the cooling tank 101 from the mounting groove 102 and causing contamination to the internal components.

[0033] The interference fit between the I-beam sleeve 21 and both sides of the cylinder head body 1, as well as the dual fixing method of locking the insert 26 and the limit seat 27, greatly improves the fixing strength of the coolant tank 37, avoids the cylinder head vibration causing the coolant tank 37 to loosen and leak at the connection with the pipe, and ensures the sealing of the cooling circuit. The spring 25-driven insert 26 structure makes the disassembly and assembly of the coolant tank 37 easier. After the cover plate 4 is fixed, there is no need to use tools and fasteners to fix the coolant tank 37, which reduces the difficulty and cost of disassembling the water circuit during later maintenance.

[0034] The working principle of this type of cylinder head with a cooling structure:

[0035] During assembly, firstly, the two I-beam sleeves are respectively snapped into the two mounting slots 102, so that the coolant tank 37 is embedded in the cooling groove 101, thereby fixing the coolant tank 37 in the left and right positions. Then, the pull rod 24 is pulled outward to move the insert 26 outward, and the cover plate 4 is installed on the cylinder head body 1 with fasteners, so that the position of the limit seat 27 corresponds to the position of the insert 26. Then, the pull rod 24 is slowly returned, so that the insert 26 passes through the fixing block 22 and is inserted into the limit seat 27, thereby fixing the coolant tank 37 in the up and down positions, thus firmly fixing the coolant tank 37 in the cooling groove 101.

[0036] During operation, the water in the storage tank 31 is cooled by the cooling plate 36, and the cooling water is sent to the inlet pipe 32 by the water pump 35. The water is then transported to the cooling water tank 37 through the inlet pipe 32. The horizontal heat dissipation channel 371 in the middle of the cooling water tank 37 increases the contact area between the cooling water and the heat, thus enhancing the cooling effect. After absorbing heat, the cooling water flows back to the storage tank 31 through the outlet pipe 33, forming a circulating cooling loop. By opening a cooling groove 101 on the upper surface of the cylinder head body 1 and installing the cooling water tank 37 in the cooling groove 101, the cooling water tank 37 can be directly close to the heat source area of ​​the cylinder head body 1, and the contact area with the heat source area is increased, thereby improving the cooling effect.

[0037] 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.
