Abstract

A test apparatus includes a plurality of rails, a plurality of test zones and a movable test chamber. The test zones are located between the rails. The movable test chamber includes a passageway, at least one heat source and at least one pair of rolling balls. The heat source is used to heat the passageway. The pair of rolling balls is movably contained in two rails, so as to facilitate movement of the passageway to different test zones.

First claim

What is claimed is:

1. A test apparatus, comprising:
a plurality of rails;
a plurality of test zones located between the rails, wherein the test zones are capable of being respectively placed with a plurality of objects to be tested; and
a movable test chamber comprising:
a passageway;
at least one heat source for heating the passageway; and
at least one pair of rolling balls respectively and movably contained in two of the rails, so as to facilitate movement of the passageway to different test zones and to enable the passageway to sequentially cover the objects to be tested.

2. The test apparatus of claim 1 , wherein the movable test chamber comprises:
a pair of walls encompassing the passageway, the rolling balls respectively being positioned on bottom surfaces of the walls.

3. The test apparatus of claim 1 , wherein the movable test chamber comprises:
a pair of heat insulation curtains for covering opposite ends of the passageway.

4. The test apparatus of claim 1 , wherein the rails comprise:
a plurality of longitudinal rails, wherein the test zones comprise a plurality of regions for the objects to be tested, and the regions for the objects to be tested are arranged between the longitudinal rails along the length direction of the longitudinal rails, and a normal line of the passageway is substantially parallel to the length direction of the longitudinal rails, wherein the normal line of the passageway is an imaginary line that passes through a front end and a rear end of the passageway.

5. The test apparatus of claim 4 , wherein the rails further comprise:
a plurality of latitudinal rails crossing the longitudinal rails, wherein the test zones comprise a plurality of buffering regions, and each of the buffering regions is encompassed by two of the longitudinal rails and two of the latitudinal rails.

6. The test apparatus of claim 1 , wherein the movable test chamber comprises:
at least one exhaust opening for exhausting air from the passageway to outside.

7. The test apparatus of claim 1 , wherein the movable test chamber comprises:
at least one intake window for outside air entering into the passageway.

8. The test apparatus of claim 1 , wherein the movable test chamber comprises:
at least one temperature sensor for detecting the temperature of the passageway.

9. The test apparatus of claim 8 , wherein the movable test chamber comprises:
at least one monitor for displaying the temperature that the temperature sensor detects.

10. A movable test chamber, comprising:
a pair of walls;
a passageway encompassed by the walls and having two opposite openings;
a pair of heat insulation curtains for covering the opposite openings of the passageway when the heat insulation curtains are unfolded and for exposing the opposite openings when the heat insulation curtains are retracted, wherein the heat insulation curtains and the walls form a test space when the heat insulation curtains are unfolded;
at least one heat source for heating the test space; and
at least one pair of rolling balls respectively positioned on the bottom surfaces of the walls,
wherein at least one of the rolling balls comprises a sphere that is free to roll relative to other portion of the rolling ball.

11. The movable test chamber of claim 10 , further comprising:
at least one exhaust opening formed on one of the walls.

12. The movable test chamber of claim 11 , further comprising:
at least one intake window formed on another one of the walls that is opposite to the exhaust opening.

13. The movable test chamber of claim 10 , further comprising:
at least one temperature sensor placed in the test space and which detects the temperature in the test space.

14. The movable test chamber of claim 10 , further comprising:
at least one monitor positioned on the outer surface of one of the walls, the monitor displaying the temperature that the temperature sensor detects.
