A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

A radiator heater cover includes a cover formed of thermoplastic in a shape that fits over at least a portion of a radiator heater. The radiator heater cover defines a plurality of apertures in at least a portion of an outer surface of the cover that are dimensioned and spaced to provide desired convective heat transfer away from predetermined areas of the radiator heater.

The invention relates to a tube register (RR) for a heat exchanger (WT), in particular a heating element or cooling element, through which a heat transfer fluid may flow, and which has two distributor lines (1, 2), between which a plurality of connecting tubes (3) extend which fluidically connect the first distributor line, also referred to as the supply distributor (1), to the second distributor line, also referred to as the return distributor (2), the tube register having a linear supply distributor (1) and a linear return distributor (2) running in parallel thereto, between which a plurality of connecting tubes (3), situated in a plane, extend, the first ends (3a) of the connecting tubes (3) in each case being fluidically connected to the supply distributor (1), and the second ends (3b) of the connecting tubes (3) in each case being fluidically connected to the return distributor (2), characterized in that the connecting sites (P1) between the supply distributor (1) and the connecting tubes (3) are situated eccentrically, relative to the center axis (M1) of the supply distributor (1), on the supply distributor (1), and the connecting sites (P2) between the return distributor (2) and the connecting tubes (3) are situated eccentrically, relative to the center axis (M2) of the return distributor (2), on the return distributor (2).
