Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows:
referring to fig. 1-4, a spiral heat dissipation brake drum comprises a drum body 1, a reinforcing ring 14 is arranged on one side of the drum body 1, a heat dissipation sleeve 2 is arranged outside the drum body 1, a heat conducting agent is arranged between the drum body 1 and the heat dissipation sleeve 2, a cavity 23 is arranged inside the heat dissipation sleeve 2, a phase change energy storage material is arranged in the cavity 23, the phase change energy storage material is preferably trisodium phosphate dodecahydrate, the phase change temperature is 70-80 ℃, and a plurality of spiral heat dissipation fins 22 are arranged outside the heat dissipation sleeve 2, so that when the drum body 1 rotates in the forward direction, the spiral heat dissipation fins 22 can generate airflow flowing through the surface of the heat dissipation sleeve 2. The heat dissipation sleeve 2 is made of materials with high strength, good heat conductivity and corrosion resistance, and titanium or stainless steel can be selected.
A plurality of convex strips 11 are arranged outside the drum body 1, and the extending direction of the convex strips 11 is parallel to the axis of the drum body 1; the inner wall of the heat dissipation sleeve 2 is provided with a plurality of grooves 21, and the raised lines 11 are located in the grooves 21. The structure can prevent the heat dissipation sleeve 2 from rotating relative to the drum body 1, and increase the heat conduction area between the heat dissipation sleeve and the drum body, thereby being more beneficial to the heat conduction of the latter to the front.
The heat conducting agent is heat conducting silicone grease, and other materials such as total loss system oil can be selected, but the heat conducting silicone grease is best, has good high temperature resistance (the highest temperature is more than 200 ℃) and is not easy to volatilize. The heat conducting agent fills the gap between the heat radiating sleeve 2 and the drum body 1, so that air in the gap is eliminated (the thermal conductivity of the air is very low), and the heat conducting capacity between the heat radiating sleeve and the drum body is greatly enhanced.
The drum body 1 is provided with a plurality of blocking blocks 3, and the blocking blocks 3 are positioned on one side of the heat dissipation sleeve 2 far away from the reinforcing ring 14. The stopper 3 prevents the heat dissipation sleeve 2 from moving in the axial direction of the drum body 1.
The stop block 3 is provided with a through hole 31, the drum body 1 is provided with a plurality of threaded holes 12, the stop block 3 is fixed on the drum body 1 through bolts, and specifically, the bolts penetrate through the through hole 31 to be in threaded connection with the threaded holes 12.
One side of the blocking block 3 is provided with a blocking sheet 32, the outer side of the blocking sheet 32 is provided with a rubber pad 33, and the other side of the rubber pad 33 is in contact with the heat dissipation sleeve 2. The rubber pad 33 has elasticity, and when the heat dissipation sleeve 2 expands due to a temperature rise, the rubber pad 33 can be compressed.
The rubber pad 33 is made of fluororubber or silicone rubber, and has good heat resistance and weather resistance.
The reinforcing ring 14 is provided with a plurality of air guide holes 13, and the extending direction of the air guide holes 13 is inclined to the axis of the drum body 1, so that when the drum body 1 rotates in the forward direction (if the wheels rotate in the forward direction when the vehicle moves forward), air flow is generated in the air guide holes 13, and the air flow has the same flow direction as the air flow generated by the spiral radiating fins 22.
The working principle is as follows: referring to fig. 1-4, when braking, the heat generated by the drum body 1 is transferred to the heat dissipation sleeve 2, and when the drum body 1 exceeds a certain temperature (above 70 ℃ if trisodium phosphate dodecahydrate), the phase change energy storage material in the heat dissipation sleeve 2 undergoes phase change, absorbs a large amount of heat, so that the temperature rise amplitude of the drum body 1 can be reduced, and the temperature rise of the drum body 1 can be prevented from being too high. When the vehicle continues to drive forwards after braking, the wheel drives the brake drum to rotate, and the air flow generated by the spiral radiating fins 22 and the air guide holes 13 can promote the radiating sleeve 2 to rapidly cool and change the phase, so that the heat absorption capacity of the radiating sleeve is recovered.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
