Abstract

A filling system that has at least one heat pipe used for heat transfer, at least one ammonia tube that pure ammonia is able to be stored at room temperature as saturated vapour, at least one delivery line that enables to deliver ammonia from the ammonia tube to the heat pipe and the heat pipe is removably engaged, at least one valve is located on the delivery line and allows ammonia flow to be controlled, at least one detector located on the delivery line and providing seal control, and at least one heater to heat the heat pipe.

First claim

The invention claimed is:

1. A filling system ( 1 ) comprising:
at least one heat pipe ( 2 ) for heat transfer;
at least one ammonia tube ( 3 ) for storing pure ammonia at room temperature as saturated vapour;
at least one delivery line ( 4 ) removably engaged to the heat pipe ( 2 ) for delivering ammonia from the ammonia tube ( 3 ) to the heat pipe ( 2 );
at least one valve ( 5 ) on the delivery line ( 4 ) for controlling ammonia flow through the delivery line ( 4 );
at least one detector ( 6 ) on the delivery line ( 4 ) and providing seal control;
at least one heater ( 7 ) for heating the heat pipe ( 2 );
a base ( 8 );
at least one chamber ( 10 ) having at least two walls ( 9 ) extending outwardly from the base ( 8 ), wherein when the heat pipe ( 2 ) is placed in the chamber ( 10 ), the heat pipe ( 2 ) remains between the walls ( 9 ), and which, when heat is radiated inside the chamber ( 10 ) by the heater ( 7 ), the heat radiated by the heater ( 7 ) being reflected through the inner sides of the walls ( 9 ) to the heat pipe ( 2 ); and
at least one cooling member ( 12 ) which, during a filling operation into the heat pipe ( 2 ), is positioned inside the chamber ( 10 ) adjacent to a first end of the heat pipe ( 2 ) opposite from a second end thereof where the at least one delivery line ( 4 ) is removably engaged to the heat pipe ( 2 ) and contacts with the heat pipe ( 2 ) to cool the heat pipe ( 2 ) so that ammonia within the heat pipe ( 2 ) is turned into a liquid phase as the heat pipe ( 2 ) is cooled from the first end thereof to the second end thereof.

2. The filling system ( 1 ) according to claim 1 , comprising at least one reflective member ( 11 ) located in the chamber ( 10 ) for reflecting the heat radiated by the heater ( 7 ).

3. The filling system ( 1 ) according to claim 1 , wherein at least one of the at least one heater ( 7 ) is an infrared heater.

4. The filling system ( 1 ) according to claim 1 , wherein the cooling member ( 12 ) is dry ice.

5. The filling system ( 1 ) according to claim 1 , comprising at least one support member ( 13 ) located on the base ( 8 ) for supporting the heat pipe ( 2 ) so that the heat pipe ( 2 ) is in a same alignment as the delivery line ( 4 ).

6. The filling system ( 1 ) according to claim 5 , wherein at least one of the at least one support member ( 13 ) is thermally insulating.

7. The filling system ( 1 ) according to claim 2 , wherein at least one of the at least one reflective member ( 11 ) is detachably attached to the chamber ( 10 ).

8. The filling system ( 1 ) according to claim 1 , comprising a reflective member ( 11 ) adhered to an inner side of the chamber ( 10 ).

9. The filling system ( 1 ) according to claim 1 , comprising a connection member ( 14 ) having a tube-fitting connection feature for connecting the heat pipe ( 2 ) to the delivery line ( 4 ).

10. The filling system ( 1 ) according to claim 1 , wherein the heater ( 7 ) faces the heat pipe ( 2 ) when the heat pipe ( 2 ) is positioned on the base ( 8 ) of the chamber ( 10 ).

11. The filling system ( 1 ) according to claim 1 , comprising at least one heat meter ( 15 ) for measuring temperature located on the delivery line ( 4 ) or the heat pipe ( 2 ), and at least one control unit ( 16 ) for adjusting a temperature output of the heater ( 7 ) depending on the temperature measured by the heat meter ( 15 ).

12. The filling system ( 1 ) according to claim 1 , wherein the chamber ( 10 ) has a U-shape.
