Problems solved by technology

Thermal power systems, especially vehicle engines, are mixed in the human living space, and their pollution emissions have a very serious impact on humans. If a cold carrier can be invented to absorb the waste heat after the engine does work, the efficiency of the engine will be effectively improved. Although the production of cold carriers requires energy, this engine can at least reduce the space configuration of pollution emissions, keep pollution emissions away from human living space, and reduce the direct impact of pollution emissions on humans

Embodiment 1

[0043] Such as figure 1 The shown ultra-low temperature heat source engine includes a gas compression mechanism 1, a gas work mechanism 2 and a gas liquefied substance source 3, and the working medium outlet of the gas compression mechanism 1 communicates with the working medium inlet of the gas work mechanism 2 through a heater 5 The working medium outlet of the gas working mechanism 2 communicates with the working medium inlet of the gas compression mechanism 1 through the cooled fluid channel of the heat exchanger 4, and the gas liquefied source 3 passes through the cooled fluid channel of the heat exchanger 4 The heating fluid passage communicates with the working fluid inlet of the auxiliary heater 6 , and the working fluid outlet of the auxiliary heater 6 communicates with the auxiliary gas working mechanism 7 .

[0044] In this embodiment, the working fluid circulating in the closed loop including the gas working mechanism 2 and the gas compression mechanism 1 is set a...

Embodiment 2

[0048] Such as figure 2 The shown ultra-low temperature heat source engine, on the basis of Embodiment 1: the gas compression mechanism 1 is set as an impeller-type gas compression mechanism 101, the gas working mechanism 2 is set as an impeller-type gas working mechanism 201, and the impeller-type The gas working mechanism 201 is provided in conjunction with the impeller-type gas compression mechanism 101 , the auxiliary heater 6 is an external combustion heater 601 , and the auxiliary gas working mechanism 7 is an impeller-type auxiliary gas working mechanism 701 .

Embodiment 3

[0050] Such as image 3 The difference between the shown ultra-low temperature heat source engine and Embodiment 2 is that the gas compression mechanism 2 is changed to a two-stage impeller type gas compression mechanism 102, and cooling is provided between the stages of the two-stage impeller type gas compression mechanism 102. device 8.

[0051] As a changeable embodiment, the gas compression mechanism 2 can also be changed to three or more stages; the cooler 8 can be set on a one-stage impeller type gas compression mechanism.

[0052] As a changeable embodiment, in all embodiments of the present invention, the gas compression mechanism 1 can be selectively set as a multi-stage gas compression mechanism with reference to this embodiment. Similarly, the gas work mechanism 2 can be selected It is permanently set as a multi-stage gas work mechanism.

Abstract

The invention discloses an ultra-low temperature heat source engine. The ultra-low temperature heat source engine includes a gas compression mechanism, a gas work mechanism and a gas liquefied source. The inlet is connected, the working medium outlet of the gas working mechanism is connected with the working medium inlet of the gas compression mechanism through the cooled fluid channel of the heat exchanger, and the gas liquefied source is heated through the heated fluid channel of the heat exchanger It communicates with the working medium inlet of the auxiliary heater, and the working medium outlet of the auxiliary heater communicates with the auxiliary gas working mechanism. The ultra-low temperature heat source engine disclosed in the present invention has the advantages of simple structure, high power density, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to an ultra-low temperature heat source engine. Background technique [0002] No matter what kind of thermodynamic cycle, reducing the exhaust heat temperature of its working fluid has a more obvious effect on improving its efficiency than increasing the heat absorption temperature of its working fluid. Thermal power systems, especially vehicle engines, are mixed in the human living space, and their pollution emissions have a very serious impact on humans. If a cold carrier can be invented to absorb the waste heat after the engine does work, the efficiency of the engine will be effectively improved. Although the production of cold carriers requires energy, this engine can at least reduce the space configuration of pollution emissions, keep pollution emissions away from human living space, and reduce the direct impact of pollution emissions on humans.
