This invention relates in general to an industrial heat exchanger package unit for transferring heat energy between cool intake air flowing into an industrial process, and hot exhaust, air flowing out of an industrial p~ocess. Each package units specifically ineludes, integral finned heat pipe heat exchangers, face and bypass ~ assemblies, tilted base frames, bypass ducts, supply inlet filter assemblies, and supply inlet louver assemblies which are arranged in such a manner as to provide a percentage of total volume control over the amount of supply or exhaust air introduced into the heat exchange chambers.
A heat exchanger, especially recuperator for high temperature reactors, comprising a prismatic extending jacket and a multiplicity of elongated hexagonal elements arranged within the jacket and essentially parallel to the primary direction or extent thereof. Each hexagonal element has a central tube and heat transfer surfaces arranged about each central tube and extending axially up to the outer contour or outline of the corresponding hexagonal element. Both ends of the heat transfer surfaces are connected to collectors seated upon the central tube. Each hexagonal element is connected by spacers with its neighboring elements and with analogous spacers spatially fixedly arranged at the region of the jacket laterally bounding the heat exchanger. The spacers have play so that the spacing between the elements and between the elements and the spatially fixedly arranged spacers can alter by the amount of such play. This play is dimensioned such that the sum of the play in any one respective direction over the cross-section of the heat exchanger still positively takes up without constraant the greatest differential expansion arising between the package of hexagonal elements and the spatially fixedly arranged spacers m such direction under extreme operating conditions.

A heat storage and/or recovery system using multiple heat storage tanks to selectively store heat from a solar collector and recover the stored heat to operate a heat driven system. The heat from the solar collector is

transferred into the storage tanks through an input heat transfer link configuration using vapor heat transfer which automatically transfers heat into a storage tank that will accept the heat but effectively prevents the flow of heat from the storage tanks back to the solar collector while the heat in the storage tanks is transferred to the heat driven system through a recovery heat transfer link configuration also using vapor heat transfer which automatically transfers heat to the heat driven system from a storage tank capable of supplying heat but effectively prevents the flow of heat from the heat driven system back into the storage tanks.

The invention relates to a heat exchanger wherein particle deposition is prevented on the inner surfaces of heat-and-mass transfer and chemical apparatus and comprises introducing into the flow of a liquid medium delivered into the apparatus solid particles which are fluidized by the medium and which exert mechanical action on the surfaces of the apparatus. The solid particles are made of a material neutral toward the medium, Also included in the invention is the provision of an apparatus for carrying out the aforedescribed method.
US 431111627. A latent heat accumulator gives up its heat when a heat exchange medium is passed through the accumulator and around a circuit containing an external heat sink. The heat storage medium in the accumulator changes its state from liquid to solid as it gives up heat. In order to prevent heat exchange medium from being trapped by the heat storage medium as it solidifies, the exchange medium is always introduced directly into a zone where the storage medium is liquid.
