Thermal energy transfer device
View Patent ↗A portable heat transfer device for transferring thermal energy to and/or from laboratory tubes, clinical vials, specimen vials, laboratory vials, serum vials, drug vials and laboratory containers is provided. The heat transfer device comprises an insulated, thermally conductive heat conduit system and base for the purpose of exchanging heat between the laboratory container and a thermoregulatory device.
1. A device for transferring thermal energy from sample vessels to a thermoregulator, said device comprising:
a thermo-conductive core comprising a base plate composed of a thermo-conductive material having an upper surface and further comprising an array of vertically extending hollow thermo-conductive columns each having an equal and constant outer diameter along an entirety of a height of each thereof and each having a terminal end coupled to the upper surface of the base plate, each having an outer surface that is spatially separated from an outer surface of adjacent thermo-conductive columns thereby forming a void between the adjacent outer surfaces, between the outer surfaces, and between the upper surface, each vertically extending hollow thermo-conductive column further comprising an opening located opposite the terminal end, and an inner surface configured to contact a sample vessel; and
a single insulating material having an array of cylindrical holes corresponding to the array of vertically extending hollow thermo-conductive columns and arranged to receive the array of vertically extending hollow thermo-conductive columns such that the insulating material entirely fills the void, such that the single insulating material contacts and encloses the upper surface of the base plate, and each outer surface of each vertically extending hollow thermo-conductive column, an outer surface of the single insulating material forming an exterior surface of the device.
2. The device of claim 1 , wherein the thermo-conductive material is a metal or metal alloy.
3. The device of claim 2 , wherein the thermo-conductive material is aluminum, an aluminum alloy, copper, copper alloy, stainless steel, titanium, zinc, or zinc alloy.
4. The device of claim 1 , wherein the insulating material is reversibly attached to the thermo-conductive core by magnets, spring clips, snap connectors, fiber and hook, interference friction fit, interlocking features, or screws.
5. The device of claim 1 , wherein the thermo-conductive columns comprise one or more tube segments.
6. The device of claim 5 , wherein the tube segment is bonded to the base by an interference friction fit, fusion weld, braze joint, solder joint, screw thread, snap ring, or adhesive bond.
7. The device of claim 1 , wherein the insulating material is polyethylene foam, urethane foam, vinyl foam, styrene foam.
8. The device of claim 1 , wherein the insulating material is a solid polymer.
9. The device of claim 1 , wherein the insulating material is permanently bonded to the thermo-conductive core by adhesive joints.
10. The device of claim 1 , wherein the insulating material is molded onto the core.
11. The device of claim 5 wherein the insulating material is polyethylene foam, urethane foam, vinyl foam, styrene foam.
12. The device of claim 5 , wherein the insulating material is a solid polymer.
13. The device of claim 5 , wherein the insulating material is removably attached to the thermo-conductive core by means of a friction fit or by magnetic attraction.
14. The device of claim 5 , wherein the insulating material is permanently bonded to the thermo-conductive core by adhesive joints.
15. The device of claim 5 , wherein the insulating material is molded onto the core.
16. The device of claim 1 , wherein the inner surface further comprises an equal and constant inner diameter along the entirety of the height of each thereof.
17. The device of claim 1 , wherein the terminal end is closed.
18. A device for transferring thermal energy from sample vessels to a thermoregulator, said device comprising:
a thermo-conductive core comprising an array of adjacent vertically extending hollow thermo-conductive columns, each column having a closed end, an open end, an inner surface configured to contact a sample vessel, an outer surface, and an equal and constant outer diameter along an entirety of a height of each column, said hollow thermo-conductive columns being arranged such that the outer surface of each column is spatially separated from the outer surface of at least two adjacent columns in the array thereby forming a void between the adjacent outer surfaces;
a base plate composed of a thermo-conductive material, to which said closed end of said columns are attached to an upper surface thereof, said void further comprising an area between the outer surface and the upper surface of the base plate; and
a single insulating material entirely filling the void, an outer surface of the single insulating material forming an exterior surface of the device.
