Embodiment 1
[0020] A free-piston internal combustion generator oscillation-driven piston cooling system mainly includes: a piston 2, a connecting rod 3, a check valve 5, and a radiator 8.
[0021] The piston 2 is a piston 2 with an oil chamber 4 and an oil passage inside;
[0022] The connecting rod 3 is a connecting rod 3 with an oil passage inside
[0023] The connection relationship is: the pistons 2 on both sides are respectively rigidly connected with the connecting rod 3 to form a piston 2 assembly. An oil passage is set inside the piston 2 assembly; an oil chamber 4 is provided at any position on the oil passage; the check valve 5 moves left and right in the oil chamber 4; the radiator 8 is fixed between the cylinder 1 and the generator; the middle part of the radiator 8 is opened There are through holes for the passage of the connecting rod 3; there are cooling fins on the surface of the radiator 8; the interior of the radiator 8 is hollow for storing cooling oil; the contact par...

The invention relates to a free-piston internal-combustion generator oscillation driving piston cooling system, and belongs to the field of energy source power. The piston cooling system mainly comprises pistons, a connecting rod, one-way valves and radiators, wherein the pistons on the two sides are rigidly connected with the connecting rod to form a piston assembly; an oil duct is formed in the piston assembly; an oil chamber is arranged in any position of the oil duct; the one-way valves move left and right in the oil chamber; the radiators are fixed between air cylinders and generators; through holes are formed in the middles of the radiators, and used for passing of the connecting rod; radiating fins are arranged on the surfaces of the radiators; the interiors of the radiators are hollow, and are used for storing cooling oil; and an oil inlet and an oil outlet are formed at contact parts of the cooling oil in the connecting rod and the radiators. The system performs oil pumping by virtue of inertia of the one-way valves, and requires no additional driving device; circulation of the cooling oil is achieved by the oil duct in the piston assembly; and heat loads of a whole piston connecting rod group and a linear generator are reduced.
Description
technical field [0001] The invention relates to an oscillation-driven piston cooling system for a free-piston internal combustion generator, which belongs to the field of energy and power. Background technique [0002] The general structure of the existing internal combustion generators is that the reciprocating internal combustion engine is connected with the rotating electrical machine through the crank connecting rod mechanism, including two types of thermal cycles of two strokes and four strokes. The disadvantages are complex structure, large volume, low thermal efficiency, and exhaust pollution. There are many things. The free piston internal combustion generator is a new type of power device that has emerged in recent years. It is directly coupled with a free piston internal combustion engine and a linear generator. It directly connects the free piston with the linear motor mover to form the only moving part—— - Piston assembly. When the system is running, the gas in...
