[0004] Therefore, a new scheme needs to be proposed to solve this problem. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a stable heat dissipation type electric cylinder.

[0006] The above technical purpose of the utility model is realized by the following technical scheme: the stable heat dissipation type electric cylinder comprises a telescopic cylinder body and a servo motor in transmission connection with the telescopic cylinder body, and a plurality of auxiliary heat dissipation pieces are detachably connected to the telescopic cylinder body along the length direction of the telescopic cylinder body.

[0007] The utility model is further provided as follows: a plurality of auxiliary heat dissipation long grooves are formed in the peripheral wall of the telescopic cylinder body, the spacing between two adjacent auxiliary heat dissipation pieces is greater than zero, and the auxiliary heat dissipation pieces are sleeved on the outer side of the telescopic cylinder body.

[0008] The utility model is further provided as follows: the auxiliary heat dissipation piece comprises an inner heat conduction pipe and an outer heat conduction pipe fixed to each other, a vertical groove is arranged symmetrically between the inner heat conduction pipe and the outer heat conduction pipe, a horizontal groove is communicated between two vertical grooves, and the vertical groove is filled with cooling liquid.

[0010] The present invention is further configured such that: the thermal conductivity of the outer wall of the telescopic cylinder is less than that of the inner heat pipe, and the thermal conductivity of the inner heat pipe is less than that of the outer heat pipe.

[0011] The present invention is further configured such that: the inner heat pipe and the outer heat pipe are provided with a plurality of heat dissipation through holes arranged in an array and communicating with each other with the auxiliary heat dissipation long slots, and the heat dissipation through holes are independent of each other from the vertical slots and the horizontal slots.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This stable heat dissipation type electric cylinder, such as Figures 1-3As shown, the structure includes a telescopic cylinder 1 and a servo motor 2 connected to the telescopic cylinder 1. Several auxiliary heat dissipation components are detachably connected to the telescopic cylinder 1 and arranged in an array along its length. The heat dissipation performance of these auxiliary heat dissipation components enhances the overall heat dissipation performance of the structure, resulting in better overall heat dissipation stability. Several auxiliary heat dissipation slots 3 are formed on the peripheral wall of the telescopic cylinder 1. These slots increase the heat exchange area between the structure and the air, further enhancing the overall heat dissipation and operational stability. The distance between two adjacent auxiliary heat dissipation components is greater than zero. The auxiliary heat dissipation components are fitted onto the outside of the telescopic cylinder 1, abutting against it. This contact allows the auxiliary heat dissipation components to absorb and dissipate heat from the telescopic cylinder 1, ensuring stable auxiliary heat dissipation and improving the overall heat dissipation stability of the structure.

[0020] like Figure 2 and Figure 3 As shown, the auxiliary heat dissipation component includes an inner heat-conducting pipe 4 and an outer heat-conducting pipe 5 fixed together by welding. A symmetrically arranged vertical groove 6 surrounds the inner heat-conducting pipe 4 and the outer heat-conducting pipe 5. A horizontal groove 7 connects the two vertical grooves 6. The horizontal groove 7 is at the top during use. The vertical groove 6 is filled with coolant, which is a mixture of water and ethanol. The coolant in the vertical groove 6 will vaporize after being heated and float into the horizontal groove 7. After the gaseous coolant releases heat and liquefies, it will flow back into the vertical groove 6 under the action of gravity. This achieves a stable heat conduction and auxiliary heat dissipation process for the coolant. At the same time, the characteristic of ethanol being easy to vaporize when heated is used to ensure that the coolant can better absorb heat and perform auxiliary heat dissipation, thus ensuring better heat dissipation stability of the auxiliary heat dissipation component and the overall structure.

[0021] like Figure 2 and Figure 3 As shown, the inner wall of the inner heat pipe 4 abuts against the outer peripheral wall of the telescopic cylinder 1. This arrangement ensures that the inner heat pipe 4 can stably contact the telescopic cylinder 1 and achieve stable absorption of heat from the telescopic cylinder 1. The outer wall of the inner heat pipe 4 located on the bottom side abuts against the inner wall of the outer heat pipe 5 located on the bottom side. This arrangement allows the outer heat pipe 5 to absorb the heat absorbed by the inner heat pipe 4 through contact, and then conduct the heat to exchange with the air and to exchange with the coolant. This ensures that the overall heat dissipation performance of the structure can be stably achieved, reduces the impact of heat on the operation of the electric cylinder, and ensures that the driving function of the electric cylinder is more stable.

[0022] like Figure 2 and Figure 3As shown, the thermal conductivity of the outer wall of the telescopic cylinder 1 is less than that of the inner heat pipe 4, and the thermal conductivity of the inner heat pipe 4 is less than that of the outer heat pipe 5. The main body of the telescopic cylinder 1 is made of aluminum alloy, the inner heat pipe 4 is made of copper, and the outer heat pipe 5 is made of silver. This ensures that the thermal conductivity of the outer wall of the telescopic cylinder 1, the thermal conductivity of the inner heat pipe 4, and the thermal conductivity of the outer heat pipe 5 increase in that order. This ensures that the heat transferred to the telescopic cylinder 1 can be stably transferred to the inner heat pipe 4, and the heat transferred from the inner heat pipe 4 to the outer heat pipe 5. This allows the auxiliary heat dissipation function of the auxiliary heat dissipation component to be stably realized, thereby ensuring that the overall heat dissipation performance of the structure can be stably realized.

[0023] like Figure 2 and Figure 3 As shown, the inner heat pipe 4 and the outer heat pipe 5 are provided with a number of heat dissipation holes 8 arranged in an array and interconnected with the auxiliary heat dissipation groove 3. The heat dissipation holes 8 are independent of the vertical groove 6 and the horizontal groove 7. This arrangement ensures that the flowing air can enter the auxiliary heat dissipation groove 3 through the heat dissipation holes 8, and the flowing air in the auxiliary heat dissipation groove 3 can flow out through the heat dissipation holes 8, so that the flowing air can better flow through the auxiliary heat dissipation groove 3 and over the auxiliary heat dissipation components, thereby further enhancing the overall heat dissipation performance of the structure.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
