Thermal control insert and thermal resistant hollow block

摘要

A thermal control insert and a thermal resistant hollow block. The thermal resistant hollow block includes a hollow block having a cavity and an elongate member positioned within the cavity that has a generally spiral shaped pathway which forms a generally closed pathway to receive a heated fluid when the elongate member is positioned within the cavity of the hollow block. The generally spiral shaped pathway passes the heated fluid in a forward direction through the generally closed pathway toward a central open area at an inner end of the generally closed pathway of the elongate member. As fluid accumulates in the central open area, the fluid loses kinetic energy and becomes stagnant to provide a relatively high thermal resistance to heat transfer.

主权项

1. A thermal control insert for a hollow block, comprising:
an elongate member adapted to be positioned within a cavity formed in a hollow block, the elongate member having a generally spiral shaped pathway, the elongate member is comprised of an insulting material, the generally spiral shaped pathway forming:
i) an outer end to be positioned in a facing relation to a heated surface of the hollow block;ii) a continuous pathway to an inner end to receive a fluid when positioned within the cavity of the hollow block, wherein the inner end is disposed away from the outer end and defines a central open area; andiii) at least six continuous changes of direction to define the spiral pathway whereby the fluid flows from the outer end towards the inner end, wherein the fluid moves along the generally spiral shaped pathway in a forward direction toward the central open area at the inner end of the generally closed pathway and the fluid accumulating in the central open area loses kinetic energy to provide a thermal resistance to heat transfer.
