Abstract
Abstract A heating system for a machine having a closed thermo-dynamic cycle, the system comprising a closed space within which several containers for heat-accumulating material are present as well as a medium transporting thermal energy by evaporation and condensation. The containers communicates with a common supply duct for heat-accumulating material, with spacing members arranged between the walls of the closed space and the containers as well as between the containers mutually.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
229 words
In a heating system for supplying thermal energy to a heater of a hot gas engine, the system being operable with a supply of meltable, heat-accumulating material, and including: a housing having walls defining a closed space which encloses said heater and which has a heat receiving portion, a plurality of containers in said space, each containing said heat-accumulating material, and each having at least one heat transmission wall, a heat transporting medium in said space, which when in liquid receives thermal energy from said container through said walls and evaporates into a vapor which flows to said heater to which the thermal energy is transferred during condensation of said vapor thereon, a porous mass having a capillary structure on the outside of said heat transmission walls of said containers, and on the inside of the housing walls whereby said porous mass transports the heat transporting medium in the liquid state between the heater, the heat receiving portion of the housing and the containers, a common supply duct communicating said supply of heat-accumulating material through said housing wall to said containers within said housing, means for controlling flow of said material through said supply duct, and spacing means in said housing between and separating said containers, and between said containers and the housing walls, this spacing means being porous and permitting flow there through of said heat-transporting medium vapor.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
32 words
A heating system according to claim 1, wherein said spacing means are formed by a porous filling mass, the pores of which have larger diameters than the pores of said porous mass.
Claim 6
Dependent Claim
16 words
A heating system according to claim 4, wherein the porous filling mass comprises compressed steel wool.
Claim 7
Dependent Claim
31 words
A system according to claim 2 wherein said spacing means are formed by a porous filling mass, the pores of which have larger diameters than the pores of said porous mass.
Claim 8
Dependent Claim
15 words
A system according to claim 2 wherein said porous filling mass comprises compressed steel wool.
Claim 9
Dependent Claim
229 words
A heat pipe system for supplying thermal energy to a heater of a hot gas engine, the system being operable with a supply of meltable, heat-accumulating material, and comprising a housing having walls defining a closed space which encloses said heater and which has a heat receiving portion, a plurality of containers in said space, each containing said heat-accumulating material, and each having at least one heat transmission wall, a heat transporting medium in said space, which when in liquid receives thermal energy from said container through said walls and evaporates into a vapor which flows to said heater to which the thermal energy is transferred during condensation of said vapor thereon, a porous mass having a capillary structure on the outside of said heat transmission walls of said containers and on the inside of the housing walls whereby said porous mass transports the heat transporting medium in the liquid state between the heater, the heat receiving portion of the housing and the containers, a common supply duct communicating said supply of heat-accumulating material through said housing wall to said containers within said housing, means for controlling flow of said material through said supply duct, and spacing means in said housing between and separating said containers, and between said containers and the housing walls, this spacing means being porous and permitting flow there through of said heat-transporting medium vapor.
