Abstract
The present invention includes a canister including an adsorption chamber. An adsorption material and a heat storage material are disposed within the adsorption chamber. The heat storage material is molded from a mixture of a plurality of microcapsules and a binder. Each of the microcapsules contains therein a heat-change material. The heat storage material is prevented from moving relative to the chamber wall of the adsorption chamber in at least one of two directions perpendicular to each other.
Claims19
A canister comprising:
- an adsorption chamber defined by a chamber wall including two walls opposed to each other;
- an adsorption material and a heat storage material disposed within the adsorption chamber, the adsorption material being capable of adsorbing or desorbing fuel vapor, and the heat storage material being capable of absorbing or dissipating latent heat in response to variation of temperature within the adsorption chamber;
- wherein the heat storage material is molded to have a predetermined shape and contains a plurality of microcapsules and a binder mixed thereto,
- each of the microcapsules contains therein a heat-change material;
- the heat storage material has a size capable of contacting or positioning proximal to the two opposed walls, so that the heat storage material can be held between the two opposed walls.
