Definitions

  • a convection pump may include a pipe, a substantially helical or screw-shaped baffle disposed or mounted inside of the pipe, a device to heat one side of the pipe, and a device to cool the opposite side of the pipe.
  • the first surface and the second surface are disposed along a substantially horizontal plane.
  • Figure 5 shows an example of a schematic illustration of a convection pump.
  • a pump (/. e. , a convection pump) that produces a pumping action without changing the dimensions of a chamber.
  • the convection pump has no moving parts.
  • the convection pump may be able to pump a gas.
  • the convection pump also may be able to compress a gas.
  • the energy input to the convection pump to pump the gas is heat.
  • the convection pump may be used to move air horizontally from one location to another location.
  • the gas passes over the axis of the baffle and contacts the cooled surface.
  • the gas will cool, which will cause it to descend.
  • The. baffle translates this tendency of the gas (Le., rising due to the hot surface and descending due to the cool surface) into further horizontal motion in the same direction.
  • a convection pump 100 includes a chamber 110 having an inlet 115 and an outlet 125.
  • a helical baffle 140 (not shown in Figure 1) is disposed within chamber 110.
  • the convection pump 100 includes a wall 112 that is heated when the pump is in operation.
  • the convection pump 100 furmer includes a wall 114 that is cooled when the pump is in operation.
  • the chamber 110 may be of any length needed to accomplish the desired gas pumping.
  • a pump may be made by connecting a plurality of the chambers 110 together in a modular fashion.
  • the outlet 125 of one chamber 110 could be attached to the inlet 115 of another chamber 110. This may allow for making a pump of a desired length, with one size of the chamber 110 being
  • a dark- colored surface may be disposed on the interior of the chamber 110 proximate the wall 112.
  • the wall 112 may be a clear material that allows for the transmission of solar energy, with the colored surface heating up so that the convection pump 100 operates.
  • FIG. 5 shows an example of a schematic illustration of a convection pump.
  • the convection pump 500 shown in Figure 5 may be similar to the convection pump 100 shown in Figures 1-3, with the chamber 510 of the convection pump 500 arranged in a spiral manner or coiled about an axis 501.
  • a plurality of fins 570 may be disposed to cool the exterior (e.g., the outer circumference) of the coil-shaped chamber.
  • the coil-shaped chamber 510 may be disposed inside of a pipe 550, with the pipe having a plurality of fins on its exterior surface for cooling.
  • a heat source may be disposed on the interior of the coil-shaped chamber 510.
  • the heat source could be an airstream carrying waste heat from an industrial process.
  • the convection pump 500 could be disposed about a tube or column carrying a hot fluid created in an industrial process.
  • a thermal gradient could be established between the outer circiimference (in thermal communication with the pipe 550) and the inner circumference of the coil-shaped chamber 510.
  • gas may enter though inlet (not shown) and be pumped to an outlet 525.
  • the chirality (e.g., right handedness or left handedness) of the helical baffle 540 within the coil-shaped chamber 510 could be specified so that a gas is pumped from the bottom of the chamber to the top. That is, the chirality of the helical baffle will detennine in-part the direction that gas is. pumped; which surface is heated and which is cooled will also determine the direction that the gas is pumped.

Abstract

L'invention concerne des systèmes, des méthodes et un appareil associés à une pompe à convection. Selon un aspect, un appareil comprend une chambre, la chambre ayant une entrée à une première extrémité de la chambre et une sortie à une deuxième extrémité de la chambre. La chambre comprend de plus une première surface et une deuxième surface, la première surface étant opposée à la deuxième surface. Un déflecteur ayant une forme pratiquement hélicoïdale est placé à l'intérieur de la chambre. Un dispositif de chauffage est configuré pour chauffer la première surface de la chambre. Un dispositif de refroidissement est configuré pour refroidir la deuxième surface de la chambre.
