Abstract
An actuator has a support plate, a pump head in thermally conductive contact with the support plate, and an actuator body. Cooling means is disposed between the support plate and the actuator body. The cooling means is configured to remove and transfer heat from the pump head to the actuator body. In one embodiment, the cooling means includes two thermally conductive plates (called cold-side and hot-side plates) and a thermoelectric device disposed in thermally conductive contact between the cold-side and hot-side plates. The cold-side plate is in thermal communication with the pump head through the support plate. The hot-side plate is in thermal communication with the actuator body. The thermoelectric device is configured to transfer heat from the cold-side plate, which is in thermal communication with the pump head, to the hot-side plate, which is in thermal communication with the actuator body, thereby removing heat from the pump head.
