Apparatus having agitator for agitating fluid

Abstract

An apparatus of a heat transfer circuit in which a heat transfer fluid with small particles circulates includes a container and an agitator. The container is located in a lower position of the apparatus in a vertical direction and defines a chamber where the heat transfer liquid passes when circulating in the heat transfer circuit. The agitator is located in the chamber to agitate the heat transfer fluid.

1 . An apparatus of a heat transfer circuit in which a heat transfer fluid with a solvent and a plurality of particles dispersed in the solvent circulates to transfer heat generated by a heat source, the solvent being water or organic solvent, the apparatus comprising:
 a container located in a lower position of the apparatus in a vertical direction and defining a chamber where the heat transfer liquid passes to circulate in the heat transfer circuit; and   an agitator located in the chamber and configured to agitate the heat transfer fluid.   
     
     
         2 . The apparatus according to  claim 1 , wherein
 the apparatus is a heat exchanger, a reserver tank, or a pipe of the heat transfer circuit.   
     
     
         3 . The apparatus according to  claim 1 , wherein
 the agitator produces a vortex in a jet of the heat transfer liquid issuing into the chamber in order to shake the jet.   
     
     
         4 . The apparatus according to  claim 3 , wherein
 the container and the agitator are a single piece,   the container defines an inlet to the chamber, and   a height of the inlet is less than a height of the chamber in the vertical direction so that the container serves as the agitator.   
     
     
         5 . The apparatus according to  claim 1 , wherein
 the container and the agitator are a single piece,   the container has a cylindrical inner surface defining an inlet to the chamber, and   the inlet extends in a direction of the tangent to the cylindrical inner surface of the container so that the container serves as the agitator.   
     
     
         6 . The apparatus according to  claim 1 , wherein
 the agitator ultrasonically vibrates the heat transfer fluid.   
     
     
         7 . The apparatus according to  claim 1 , wherein
 the agitator includes a driven portion and a rotator that rotates with the driven portion.   
     
     
         8 . The apparatus according to  claim 7 , wherein
 the rotator is positioned below the driven portion in the vertical direction, and   the driven portion is driven by the heat transfer liquid flowing into the chamber.   
     
     
         9 . The apparatus according to  claim 7 , wherein
 the driven portion is driven by power supply from a starter of an engine or a motor of a vehicle.   
     
     
         10 . The apparatus according to  claim 7 , wherein
 the driven portion is driven by power generated when a door of a vehicle is opened and closed.   
     
     
         11 . The apparatus according to  claim 1 , wherein
 the agitator includes a cylindrical column, and   the cylindrical column produces a Karman vortex when the heat transfer fluid flowing into the chamber hits the cylindrical column.   
     
     
         12 . The apparatus according to  claim 1 , wherein
 the agitator includes a film having a fixed end on one side and a free end on the other side, and   the free end of the film floats in the heat transfer fluid when the heat transfer fluid flows into the chamber.   
     
     
         13 . The apparatus according to  claim 1 , wherein
 the agitator includes an inlet passage for the heat transfer fluid to the chamber, and   the inlet passage extends obliquely downward toward the chamber.   
     
     
         14 . The apparatus according to  claim 1 , wherein
 the agitator includes an inlet passage for the heat transfer fluid to the chamber, and   the inlet passage is connected to a bottom of the container in such a manner that the heat transfer fluid flows upward in the chamber.
