Description

Technical Field

[0001] The utility model relates to the field of cylinder cooling structures, in particular to an air-cooled cylinder. Background Art

[0002] The cylinder refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air converts thermal energy into mechanical energy through expansion in the engine cylinder, and the gas is compressed by the piston in the compressor cylinder to increase the pressure.

[0003] However, in the prior art, when the cylinder is used for a long time, the outer wall of the cylinder gradually increases in temperature due to friction. The cylinder is kept in a high temperature state for a long time, which may easily lead to damage of the seal, thereby damaging the cylinder. The common cooling method is to stop the machine and cool it at room temperature or spray cooling water, but the above method is difficult to achieve rapid cooling.

[0004] If an air cooling structure is added to the cylinder alone, due to the lack of corresponding structure, the contact time between the cooling air and the cylinder wall is limited, resulting in low cooling efficiency using only the air cooling structure.

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an air-cooled cylinder, which can effectively improve the cooling efficiency while achieving rapid cooling of the cylinder through the heat dissipation component, so as to solve the technical defects proposed by the background technology.

[0008] Preferably, shell one and shell two are connected through a connecting pipe, the cross-section of the air guide plate is a trapezoid with a small left side and a large right side, a through hole is opened at the center of the air guide plate, the movable rod is movably installed in the through hole, and an air outlet gap is set between the through hole and the movable rod.

[0009] Preferably, the heat dissipation fins are specifically arranged in a spiral shape, and the heat dissipation fins enclose a heat dissipation cavity. The second air inlet pipe is connected to the heat dissipation cavity, and the connecting pipe connects the heat dissipation cavity with the interior of the second shell.

[0010] Preferably, two connecting pipes are provided, and the connecting pipes are symmetrically arranged with the center axis of the cylinder body as an axis.

[0011] Preferably, a fixing block is fixedly mounted on the shell, a connecting ear is fixedly mounted on the fixing block, and two connecting ears are provided, and the connecting ears are symmetrically arranged.

[0012] Preferably, an intake pipe three is fixedly mounted on the shell one, and the intake pipe three passes through the shell one and is fixedly connected to the cylinder body, and the piston is located between the intake pipe one and the intake pipe three.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model uses the shell 1 and the shell 2 in cooperation. When used for a long time, cold air is transported to the inside of the shell 1 through the air intake pipe 2. The cold air absorbs the heat of the outer wall of the cylinder body in the shell 1 and the shell 2, and then is discharged from the shell 2, thereby realizing rapid cooling of the cylinder;

[0015] (2) The utility model uses the air inlet pipe 2 and the heat dissipation fins. When the cylinder is used for a short time, there is no need to transport cold air to the shell 1. The heat dissipation fins fixedly installed on the outer wall of the cylinder body conduct the heat of the outer wall of the cylinder body to the shell 1, and the shell 1 with a larger surface area is used to achieve rapid heat dissipation of the cylinder body.

[0016] When used for a long time, cold air is transported to the inside of shell one through air inlet pipe two, and the cold air is guided by heat dissipation fins, which effectively prolongs the residence time of the cold air and effectively improves the cooling efficiency. At the same time, the heat dissipation fins absorb the heat of the cylinder and then come into contact with the cold air, which effectively increases the contact area and further improves the cooling efficiency of the cylinder.

[0025] Embodiment 1:

[0026] This embodiment is used to solve the problem in the prior art that during the use of the cylinder, after long-term use, the outer wall of the cylinder gradually increases in temperature due to friction, and the cylinder is in a high temperature state for a long time, which can easily cause damage to the seal and further damage the cylinder. Common cooling methods are shutdown and room temperature cooling or spraying cooling water, but the above methods are difficult to achieve rapid cooling.

[0028] A heat dissipation assembly 2 is fixedly installed outside the cylinder body 1, and the heat dissipation assembly 2 includes a heat dissipation fin 201, a shell 1 202 and a shell 2 203. The cylinder body 1 is located inside the shell 1 202 and the shell 2 203. The heat dissipation fin 201 is located between the shell 1 202 and the cylinder body 1. Both ends of the heat dissipation fin 201 are fixedly connected to the shell 1 202 and the cylinder respectively. An intake pipe 204 is fixedly installed on the shell 1 202. The intake pipe 204 is arranged close to the intake pipe 1 103. An air guide plate 205 is fixedly installed on one end of the shell 203 close to the moving rod 101.

[0029] Shell 1 202 is connected to shell 2 203 through a connecting pipe 206. Two connecting pipes 206 are provided. The connecting pipes 206 are symmetrically arranged with the central axis of the cylinder body 1 as the axis. The cross-section of the air guide plate 205 is a trapezoid with a small left side and a large right side. A through hole 207 is opened at the center of the air guide plate 205. The moving rod 101 is movably installed in the through hole 207. An air outlet gap is provided between the through hole 207 and the moving rod 101. When cooling air is input into the interior of shell 1 202 through the air intake pipe 204, the cooling air is transported to shell 2 203 through the connecting pipe 206 and then discharged through the air outlet gap.

[0030] During long-term use, cold air is delivered to the interior of shell 1 202 through air intake pipe 2 204 . After the cold air absorbs the heat of the outer wall of cylinder 1 inside shell 1 202 and shell 2 203 , it is discharged from shell 2 203 , thereby realizing rapid cooling of the cylinder.

[0031] Embodiment 2:

[0032] This embodiment is used to solve the problem that if an air cooling structure is added to the cylinder alone, due to the lack of a corresponding structure, the contact time between the cooling air and the cylinder wall is limited, resulting in low cooling efficiency when using only the air cooling structure.

[0033] See also Figure 4 - Figure 5 As shown, the utility model also includes a heat dissipation fin 201, which is specifically spirally arranged. The heat dissipation fin 201 encloses a heat dissipation cavity. The air intake pipe 204 is connected to the heat dissipation cavity.

A fixing block 208 is fixedly installed on the shell 1 202, and a connecting ear 209 is fixedly installed on the fixing block 208. There are two connecting ears 209, which are symmetrically arranged. The connecting ears 209 are used to achieve fixed installation of the cylinder.

[0034] When the cylinder is used for a short time, there is no need to supply cold air to the shell 1 202. The heat from the outer wall of the cylinder 1 is transferred to the shell 1 202 through the heat dissipation fins 201 fixedly installed on the outer wall of the cylinder 1. The cylinder 1 is quickly cooled through the shell 1 202 with a larger surface area.

[0035] When used for a long time, cold air is transported to the inside of shell 1 202 through air inlet pipe 2, and the cold air is guided by heat dissipation fins 201 to extend the residence time of the cold air, effectively improving the cooling efficiency. At the same time, heat dissipation fins 201 absorb the heat of cylinder body 1 and then come into contact with the cold air, effectively increasing the contact area and further improving the cooling efficiency of cylinder body 1.

[0036] In combination with Example 1 and Example 2, by using the heat dissipation fins 201, shell 1 202 and shell 2 203 in coordination, when used for a short time, the heat from the outer wall of the cylinder body 1 is conducted to the shell 1 202, and the cylinder body 1 is quickly cooled by the shell 1 202. When used for a long time, the cold air is guided through the heat dissipation fins 201, and the residence time of the cold air is prolonged, thereby effectively improving the cooling efficiency. At the same time, the heat dissipation fins 201 absorb the heat of the cylinder body 1 and then come into contact with the cold air, thereby effectively increasing the contact area and further improving the cooling efficiency of the cylinder body 1.

[0037] The working process and principle of the utility model are as follows:

[0038] First, when the cylinder is used for a short time, there is no need to supply cold air to the shell 1 202. The heat from the outer wall of the cylinder 1 is transferred to the shell 1 202 through the heat dissipation fins 201 fixedly installed on the outer wall of the cylinder 1. The cylinder 1 is quickly cooled through the shell 1 202 with a larger surface area.

[0039] Furthermore, when the cylinder is used for a long time, cold air is transported to the inside of the housing 1 202 through the air inlet pipe 2, and the cold air is guided by the heat dissipation fins 201, which effectively improves the cooling efficiency. At the same time, the heat dissipation fins 201 absorb the heat of the cylinder 1 and then contact with the cold air, which effectively increases the contact area and further improves the cooling efficiency of the cylinder 1.

[0040] In summary, the utility model provides a heat dissipation assembly 2, which can effectively improve the cooling efficiency while achieving rapid cooling of the cylinder.
