The present invention relates to a heat exchanger (20) comprising a protective device (1), mutually parallel tubes (22) through which a first fluid circulates, and perpendicular fins (26) connecting two successive flat tubes (22), a second fluid circulating between said flat tubes (22) by passing through said fins (26), said protective device (1) being apertured so as to allow the circulation of the second fluid through the fins (26), said protective device (1) comprising fixing spikes (7) which are inserted forcibly between the fins (26).

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.

Novel method of shielding hot surface and improving panel heaters (1). The method relates to new system of shield comprising of shield (3) and corner pieces (2) that not only cover the hot surface of panel heaters (1) but also facilitates second path of convection currents for space heating by maintaining optimum current space.

This invention relates to a rotary flame heater, comprising a burner, a first wind wheel, a second wind wheel and a glass tube set in sequence from bottom to top; one side of the burner is set with an ignition device, the first wind wheel and second wind wheel are annular, a plurality of first air inlet passages are aslant set on a side wall of the first wind wheel, a plurality of second air inlet passages are aslant set a side wall of the second wind wheel, the inclined direction of the plurality of first air inlet passages is the same with that of the second air inlet passages. The advantage of this invention is to make full use of the combustion space, increase the contacting area with the glass tube and increase the calorific value when burns the same gas, which achieves a better heating effect.
