[0002] At present, the aluminium heat cylinder usually adopts smooth outer wall and inner wall design, although the material itself has good heat conductivity, but due to the limited surface area of the cylinder, the heat conduction efficiency is limited, this design is often shown obvious shortage when facing the scene needing fast heat dissipation or high efficient uniform heat transfer, for example, in industrial production, the heat dissipation speed of aluminium heat cylinder is limited due to the insufficient contact area of outer surface and air, and temperature control uneven problem is easily caused. In addition, the inner wall of traditional aluminium heat cylinder adopts smooth design, although it is beneficial to the smoothness of fluid flow, but at the same time, the contact area of heat fluid and cylinder inner wall is reduced, and the heat exchange efficiency is reduced, especially in the application scene of high temperature or high efficient heat exchange requirement.
[0003] At the same time, this design also puts forward higher requirement to the overall energy consumption of equipment, needs to rely on larger power heating or cooling system to make up for the deficiency of heat conduction efficiency, thereby indirectly increases the cost and environmental burden of industrial operation.

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0018] Referring to Figs. 1-2The application discloses a grooved aluminum heat cylinder, which comprises a cylinder body 1, wherein an outer surface of the cylinder body 1 is provided with cylinder grooves 2 which are distributed in the axial direction, the depth of the cylinder grooves 2 is 3 mm, the width of the cylinder grooves 2 is 2 mm, the length of the grooves is consistent with the height of the cylinder body, the two side edges of the grooves are circular arc transition, an inner surface of the cylinder body 1 is provided with continuous guide grooves 5 in the axial direction, the guide grooves 5 are uniformly distributed in the axial direction, the upper end of the cylinder body 1 is a cylinder port 3, the cylinder port 3 adopts an open design, and the input of hot fluid or cold fluid is facilitated, the lower end of the cylinder body 1 is a cylinder bottom 4, the cylinder bottom 4 is an integrated structure with the cylinder body 1 and is integrally formed, the cylinder bottom has a certain thickness and can bear a higher pressure, and the middle of the cylinder body 1 is designed as a hollow structure to form a channel for fluid flow and keep a uniform thickness between the inner wall and the outer wall.
[0019] The design of the cylinder grooves 2 can significantly increase the heat dissipation area of the outer surface of the cylinder body, so that the cylinder body has better heat dissipation performance in high-temperature operation or rapid cooling process. The cylinder grooves 2 extend to the cylinder bottom 4 in the axial direction of the cylinder body, the groove bottom is smoothly transitioned to the surface of the cylinder bottom, and the problems of thermal resistance and strength caused by structure mutation are avoided. The depth and spacing of the grooves can be adjusted according to the use requirement, for example, in the application with high heat dissipation requirement, the number and depth of the grooves can be appropriately increased to further improve the heat conduction efficiency.
[0020] The guide grooves 5 are uniformly distributed from the cylinder port 3 to the cylinder bottom 4, so that the fluid forms a vortex effect when passing through the aluminum heat cylinder, the contact area of the fluid and the inner wall of the cylinder body is increased, and therefore high-efficiency heat exchange is realized. The number and spacing of the guide grooves 5 can be designed according to the use requirement, when the fluid flow speed is low, the larger spacing can reduce the fluid resistance, and when the flow speed is high, the smaller spacing can provide more heat exchange area.
[0021] In the actual use, the aluminum heat cylinder in the embodiment can be used in various heating, cooling or heat exchange scenes. After the hot fluid enters from the cylinder port 3, the hot fluid flows in the cylinder body under the guidance of the guide grooves 5 and is in full contact with the inner wall of the cylinder body, so that the heat is efficiently transmitted to the outside of the cylinder body. The existence of the cylinder grooves 2 can quickly dissipate the heat to the external environment, forming an efficient heat conduction system combining the inside and the outside. Compared with the traditional aluminum heat cylinder with smooth wall surface design, the design can significantly improve the heat conduction rate, while the structure is light and the cost is low.
