Abstract
Energy efficiency of a thermal zone in an analytical instrument is improved by use of an oven housing module having an enclosure body defining an oven cavity, wherein the enclosure body exhibits a size and shape sufficient to receive a component to be subjected to temperature control within a thermal zone located in the oven cavity. A temperature control assembly includes a vent assembly communicating with ambient air, a fan, and a fast cooling flap, wherein the temperature of the thermal zone may be modulated by supplementing the oven cavity air with ambient air. The fast cooling flap may be operated for opening one side of the oven cavity to ambient conditions such that ambient air may be rapidly introduced to the oven cavity and the cavity air may be rapidly exhausted from the oven cavity for rapid cooling of the thermal zone. The oven cavity is very compact so as to allow only a marginal amount of cavity volume to be disposed about the temperature-controlled component, so as to permit efficient circulation of cavity air around the component for efficient temperature control of the component, and yet minimize the volume of the oven cavity, thus reducing the effective thermal mass of the enclosure body.
