Abstract
A set of heat pipes for solar collectors is provided. The set includes a plurality of heat pipes, each heat pipe being suitable for being laid out in a respective solar collector, and including a heat pipe fluid, a first sheet and a second sheet locally merged with each other and delimiting a reservoir. The reservoir containing the heat pipe fluid extends over a hot part for evaporating the heat pipe fluid and a cold part for condensing the heat pipe fluid, and is formed by an interstice between the two sheets. The reservoirs of at least two heat pipes are delimited by a same first sheet and a same second sheet.
Claims25
A set of heat pipes for solar collectors, the set comprising a plurality of heat pipes:
- each heat pipe being capable of being-laid out in a respective solar collector;
- each heat pipe comprising a heat pipe fluid, a reservoir, a first sheet and a second sheet joined with each other to form the reservoir therebetween,
- wherein the first sheet and the second sheet each having an inner surface and an outer surface such that the outer surface of the first sheet faces the inner surface of the second sheet;
- the reservoir of each heat pipe containing the heat pipe fluid, each reservoir includes a hot part for evaporating the heat pipe fluid and a cold part for condensing the heat pipe fluid, and
- each of the reservoirs being formed in an interstice between the outer surface of the first sheet facing the inner surface of the second sheet,
- wherein the reservoir of at least two of the plurality of heat pipes are formed by the first sheet and the second sheet,
- wherein the cold parts of said at least two of the plurality of heat pipes are connected with each other and the hot parts of said at least two of the plurality of heat pipes are separated from each other.
A method for manufacturing a set of heat pipes for solar collectors, comprising a plurality of heat pipes, the method including the steps of:
- assembling a first sheet and a second sheet forming between them a plurality of reservoirs of at least two heat pipes, while maintaining a connecting portion between two adjacent heat pipes among said at least two heat pipes, wherein each of the plurality of reservoirs being formed in an interstice between the outer surface of the first sheet facing the inner surface of the second sheet,
- cutting the set of heat pipes according to the external outline of each of hot parts, such that the hot parts of the heat pipes are separate and configured to be inserted into respective solar collectors, and
- filling the reservoirs with a heat pipe fluid.
