TESTING APPARATUS FOR PREVENTING FREEZING OF RELAYS IN ELECTRICAL COMPONENTS
First Claim
1. A test chamber for simulating low temperature and high humidity atmospheric conditions comprising:
- a chamber with temperature control configured to control a temperature of an internal atmosphere of the chamber;
a humidifier in fluid communication with the internal atmosphere of the chamber configured to supply humidified air to the internal atmosphere; and
a sealable opening in a wall of the chamber and configured to pass a wire harness from external the chamber to inside the chamber while maintaining a sealed environment within the chamber, wherein the temperature control is configured to maintain a sub-zero temperature in the internal atmosphere while the humidifier maintains a saturated internal atmosphere.

Abstract
Disclosed herein are embodiments of testing apparatus used to prevent freezing of relays in electrical components, particularly electrical components used in vehicles. One embodiment of a testing apparatus comprises a chamber with temperature control configured to control a temperature of an internal atmosphere of the chamber and a humidifier in fluid communication with the internal atmosphere of the chamber configured to supply humidified air to the internal atmosphere. A sealable opening in a wall of the chamber is configured to pass a wire harness from external the chamber to inside the chamber while maintaining a sealed environment within the chamber. The temperature control is configured to maintain a sub-zero temperature in the internal atmosphere while the humidifier maintains a saturated internal atmosphere.
