Abstract:
1. A home heating radiator using a heat transfer fluid operating in phase change form, comprising: a reservoir of said heat transfer fluid; a heat source, consisting of an electric resistance, for raising the temperature of said heat transfer fluid in the reservoir to a temperature such as to cause a phase change of said fluid; a heating body where heat transfer takes place with the ambient air, comprising a number n of channels, communicating in the lowermost part of the reservoir, where n is at least equal to 1, wherein the heat transfer fluid flows upward in each of the number n of channels and flows downward in the same channel of the number n of channels, and wherein the cross section S of the connecting zones separating the heat transfer fluid reservoir from the channels constituting the heating body, is equal to or greater than the expression: where: P denotes the power of the electric resistance; and A is a constant which depends on the type of fluid and the temperature thereof.
