Problems solved by technology

[0003] In the prior art, there are mainly two types of micro-thermal power generation devices: one is to use gas to drive the impeller to rotate and then drive the generator to generate electric energy; this type of micro-generation system is connected to the main board of the power supply object, which is easy to generate high temperature. The circuit has a certain influence; the other type uses a miniaturized piston engine as the power source to drive the generator to run. In order to obtain a higher power density, this type of equipment has a higher speed and is prone to generate greater vibration and noise.

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 As shown, the micro-miniature thermal power generating device of the present invention includes an engine assembly and a generator rotor 1, the engine assembly is an axial piston type, and a cam (such as an end face cylindrical cam) is used as a main power conversion component to convert the up and down reciprocating motion of the piston into the rotary motion of the cam. The main axis of the axial piston engine is parallel to the cylinder axis arranged in the circumferential direction. It has the advantages of compact structure and high power density. It is more suitable for the power source of the miniaturized mobile power generation device. The generator rotor 1 is directly connected with the cam and is organically combined. The engine assembly adopts an opposed arrangement structure, and the two cylinder ...

Abstract

The invention discloses a microminiature thermo-motive power generating set, comprising an engine pack and a generator rotor; the engine pack is an axial piston, and a cam is used for converting the up down reciprocating motion of a piston into the rotation motion of the cam; the generator rotor is directly connected with the cam, and two air cylinder bodies in the engine pack are arranged on two sides of the cam oppositely respectively. The microminiature thermo-motive power generating set has the advantages of simple and compact structure, simpleness in control, high working reliability, high efficiency and the like.

Description

technical field [0001] The present invention mainly relates to the field of miniature power generation equipment, in particular a micro-miniature thermal power mobile power generation device with high power density, especially refers to a power range of 100W to 1000W, a device weight below 1.5Kg, and a volume of less than 0.002m 3 portable power generators. Background technique [0002] At present, with the increasing popularity and performance improvement of personal portable digital devices, the demand for portable energy devices is increasing, and traditional chemical batteries can no longer meet them. Many scientific research institutions at home and abroad have carried out or are carrying out the design of new concept miniature mobile power supplies. Relevant basic research shows that the theoretical power density of mobile power supplies driven by micro engines is nearly 100 times that of existing batteries, and can be added Fuel reuse. [0003] In the prior art, the...
