3.2 ‐‐ Elements of Air Management

Two elements of a successful in‐device air management system are a means for allowing controlled air access to the battery and an air plenum for even air distribution. An air plenum is an air gap, or volume, which has access to all of the air holes on the battery. The air plenum allows for more even air distribution over the battery air holes, and it provides a reserve of air immediately available to the battery to handle peak power needs. Controlling air access to the battery is accomplished by creating an access path to the sealed volume of air within a device. The air access path is designed to allow a desired amount of air to flow to the sealed volume of air, which includes the plenum, either continuously or intermittently. A sealed volume of air can be created by sealing an entire device, a portion of the device including the battery compartment, or just a plenum above the air hole side of the battery. The power requirements of the device determine the rate at which air is required to flow to the battery.

Figure 12 illustrates a simple, cost effective air management solution designed into a device. The compartment door contains an o‐ring which seals against the air hole side of the battery when the door is closed. The air plenum volume is defined by the compartment door and the sides of the o‐ring. A slide switch is located in the compartment door to create an air access point. The slide switch acts as a valve which seals the compartment when in the closed position and allows air to flow to the battery when in the open position. The slide switch could be mechanically manipulated by the user or electronically controlled by the device.
