Patent ID: 8910757

Claim:
A heat-dissipating device for hydraulic brake system, including: a heat-dissipating element, being hollow and having a fixation end and a connecting end corresponding to each other, the fixation end being connected to and communicated with a brake mechanism, the connecting end being received in an oil tube so that the heat-dissipating element and the oil tube are tightly connected and communicated with each other via the connecting end, and the heat-dissipating element having a heat-dissipating portion disposed between the fixation end and the connecting end; a sleeve element, sleeved around a joint portion of the heat-dissipating element and the oil tube and disposed at the connecting end of the heat-dissipating element, and the sleeve element serving to strengthen the combination of the heat-dissipating element and the oil tube and improve leakage-proof effect; and a plurality of heat-dissipating tube units, sleeved around the oil tube and sequentially connected, and one of the heat-dissipating tube units abutting against the sleeve element; wherein the connecting end is coaxially received in the oil tube; wherein the connecting end, the oil tube and the sleeve element are coaxially arranged and radially overlapped; wherein the heat-dissipating tube units are detachably sequentially connected.
