Embodiment Construction

[0009] The invention includes a compression chamber, a heater, a regenerator, a cooler, an expansion chamber, a miniature fan and related connecting equipment. Firstly, ice cubes are added into the cold chamber, and then the hot chamber is supported by hands so that the palm surface and the hot chamber are fully contact, thereby driving the micro fan to run for a long time.

[0010] Main operation process of the present invention:

[0011] 1. Add ice cubes to the cold chamber, so as to increase the temperature difference between the cold and heat sources;

[0012] 2. Use the heat of the human palm as a low-grade heat source to drive the stirring engine;

[0013] 3. Using the Stirling engine, the miniature fan can be driven to rotate through the connection of the shaft.

[0014] It has been tested that the thermal efficiency of the Stirling engine exceeds 35%.

Abstract

The invention discloses an energy-saving miniature fan driven by a Stirling engine. The energy-saving miniature fan comprises a compression cavity, a heater, a reheater, a cooler, an expansion cavity, a miniature fan and relevant connecting equipment. When the energy-saving miniature fan is used, ice cubes are added into a cold cavity at first, then a user holds a hot cavity by the hands, and the surfaces of the palms of the user are in sufficient contact with the hot cavity, so that the miniature fan can be driven to run for a long time. The energy-saving miniature fan has the advantages that batteries can be omitted, the user does not need to press the energy-saving miniature fan by the hands, only the surfaces of the palms of the user need to be in sufficient contact with the hot cavity, and the ice cubes which are produced by a household refrigerator need to be placed in the cold cavity in advance; low-grade heat sources are sufficiently utilized by the energy-saving miniature fan, the Stirling engine is creatively utilized, accordingly, problems in life can be solved, and the transportation comfort can be improved; similar devices are modified and are high in efficiency, energy can be saved, and accordingly the energy-saving miniature fan is extremely high in economic benefit and market adaptability.

Description

technical field [0001] The invention relates to a miniature fan, in particular to an energy-saving miniature fan driven by a Stirling engine. Background technique [0002] With the development of the economy, public transportation is changing with each passing day. During the rush hour of commuting in summer, public transportation such as subways has a high density of people. Portable, energy-saving micro fans can bring people a cool and comfortable environment. There are two types of portable fans on the market today: one is a battery-driven miniature fan; the other is a manually pressed miniature fan. [0003] A micro fan with the following structure is disclosed in the patent CN 202441629 U: it includes a fan housing, fan blades, a switch and a power supply, a motor is installed in the housing, and it also includes a base and a bracket, one end of the bracket is connected to the The base is hinged, and the fan casing is hinged to the other end of the bracket; the power ...
