Temperature difference drive upper-lower conjugated pump system

Abstract

The invention relates to a temperature difference drive upper-lower conjugated pump system. The temperature difference drive upper-lower conjugated pump system comprises an upper temperature difference drive pump and a lower temperature difference drive pump. The upper temperature difference drive pump and the lower temperature difference drive pump are connected through an upper-lower conjugatedconnection rod. The upper temperature difference drive pump and the lower temperature difference drive pump are each internally provided with a phase-change working medium and a temperature adjustingdevice used for adjusting the temperature of the phase-change working medium. According to the temperature difference drive upper-lower conjugated pump system, by independently controlling the heat absorption expansion time and the cooling shrinkage time of the two independent temperature difference drive pumps which are connected, the working medium phase change or working medium PVT converting heat absorbing expansion (or cooling shrinkage) of the upper temperature difference drive pump on one side and the working medium phase change or working medium PVT converting cooling shrinkage (or heat absorbing expansion) of the lower temperature difference drive pump on the other side are synchronously carried out, intercoordination and supplementation are carried out, the two pumps achieve a conjugated coordination effect, the running speed of the pumps can be accelerated, and a better outward acting effect can also be achieved.

Description

technical field [0001] The invention relates to the technical field of energy drive and energy conversion, in particular to a temperature difference driven mysterious conjugate pump system. Background technique [0002] There are many medium and low temperature heat sources in nature and in the process of human production and life. The existing medium and low temperature heat sources mostly use heat pump technology to concentrate the heat so that it can be used at a higher temperature, but the way to use it is very limited, and the use of Extremely inefficient. At present, there is a technology that drives the pumping medium through temperature difference, and drives the reciprocating motion of the piston through intermittent temperature difference changes to achieve external work. In the disclosed temperature difference driven pump technology, there is a lack of effective control of the temperature difference driven heating and cooling process speed, the heating and coolin...

AI Technical Summary

Problems solved by technology

In the disclosed temperature difference driven pump technology, there is a lack of effective control of the temperature difference driven heating and cooling process speed, the heating and cooling process is relatively long, the operating speed of the temperature difference driven pump is not high, and more temperature difference driven equipment needs to be configured, which affects In order to achieve the development of industrialization, it is necessary to solve the problem of low operating speed of the temperature difference driven pump in order to improve the transmission efficiency and economy.
