Abstract

At least some aspects of the present disclosure feature a tubular convective device, comprising: a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, and a plurality of apertures disposed on the first portion of the blown film. At least some aspects of the present disclosure feature a tubular convective system including a plurality of tubular convective devices, where adjacent tubular convective devices are connected.

First claim

What is claimed is:

1. A tubular convective device, comprising:
a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, the convective device having two openings that allow an inflating medium source to connect and provide inflating medium,
an air-guide element configured to direct flow of inflating medium when the tubular convective device is bent, wherein the air-guide element comprises a guiding seal extending from an edge of the tubular convective device toward an inner surface of the tubular convective device, and
a plurality of apertures disposed on the first portion of the blown film.

2. The tubular convective device of claim 1 , wherein the plurality of apertures are only disposed on the first portion of the blown film.

3. A tubular convective system, comprising:
a plurality of tubular convective devices, each tubular convective device comprising:
a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, the convective device having two openings that allow an inflating medium source to connect and provide inflating medium,
an air-guide element configured to direct flow of inflating medium when the tubular convective device is bent, wherein the air-guide element comprises a guiding seal extending from an edge of the tubular convective device toward an inner surface of the tubular convective device, and
a plurality of apertures disposed on the first portion of the blown film,

wherein adjacent two of the plurality of tubular convective devices are connected, and a dispenser.

4. The tubular convective system of claim 3 , further comprises:
a line of weakness between two adjacent tubular convective devices of the plurality tubular convective devices.

5. The tubular convective system of claim 3 , further comprises:
an close seal between two adjacent tubular convective devices of the plurality tubular convective devices.

6. The tubular convective system of claim 4 , further comprises:
an close seal between two adjacent tubular convective devices of the plurality tubular convective devices, wherein the close seal is disposed proximate to the line of weakness.

7. The tubular convective system of claim 3 , wherein two of the plurality of tubular convective devices have different length from each other.

8. The tubular convective system of claim 3 , wherein each tubular convective device comprises an attachment device.

9. The tubular convective system of claim 8 , wherein the attachment device comprises an adhesive strip.

10. A tubular convective system, comprising:
a tubular convective device comprising:
a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, the convective device having two openings that allow an inflating medium source to connect and provide inflating medium,
an air-guide element configured to direct flow of inflating medium when the tubular convective device is bent, wherein the air-guide element comprises a guiding seal extending from an edge of the tubular convective device toward an inner surface of the tubular convective device, and
a plurality of apertures disposed on the first portion of the blown film; and

a fixation element configured to secure a first part of the tubular convective device.

11. The tubular convective system of claim 10 , wherein the fixation element comprises a ring.

12. The tubular convective system of claim 10 , wherein the fixation element comprises a flat element and a flexible element attached to the flat element.

13. The tubular convective system of claim 12 , wherein a flexible element is attached to the flat element at a first end and the flat element is configured to releasably attach to the flexible element proximate to a second end.

14. The tubular convective system of claim 13 , wherein the flexible element is configured to wrap around the tubular convective device.

15. The tubular convective system of claim 10 , further comprising:
a hose manifold comprising: a hose connector configured to connect to a hose, two outlet connectors configured to connect to two ends of the tubular convective device respectively, wherein the hose connector and the two output connectors are in fluid connection.
