Heat pump or heat exchange device with periodic positive and reverse pumping

Abstract

The present invention discloses that the conventional applications for heat pump or heat exchange devices are further made to be the functional structure having periodic positive and reverse directional pumping, wherein either one of the pumping flow directions of the primary side fluid piping for passing by primary side fluid or secondary side fluid piping for passing by secondary side fluid are driven by the periodic positive and reverse flow directional pump to timely improve the temperature distribution status between the primary side fluid and secondary side fluid as well as reduce the defects of impurity accumulations in fixed flow directions.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat pump or heat exchange device with periodic forward and reverse pumping. Background technique [0002] Conventional heat pump or heat exchange device, only for the primary side pipeline through the primary side fluid, or for the secondary side pipeline through the secondary side fluid, by using the pumping device to pump the fluid of the fluid line Pumping in a fixed direction, so that the fluid takes away heat for heat exchange and changes the temperature distribution of the fluid pipeline. [0003] figure 1 It is a schematic block diagram of the main structural principle of a conventional heat pump or heat exchange device with a fixed flow direction; figure 1 As shown in , the primary side fluid (10) is pumped through the primary side fluid pipeline (101) by the one-way fluid pump (120) in a fixed one-way direction, and the primary side fluid (10) passes through t...
