DIGITAL VIDEO CAMERA

摘要

A digital video camera, including a heat management system, which includes at least one inlet and at least one outlet in the housing to enable air to flow through the housing. The heat management system also includes a first heat sink thermally connected to an image sensor(s), and a second heat sink thermally connected to a data processing unit(s), and a centrifugal fan. The centrifugal fan is configured to draw air into the front of the fan in an axial direction and push air radially out in a sideways direction, whereby air travels through the inlet(s) over the first heat sink and then over the second heat sink to the outlet(s).

1. A digital video camera, including:
a housing; at least one image sensor to convert light into electrical signals; an optical system associated with the image sensor; a lens mount for releasably engaging a lens or other optical module; data processing unit(s) to process image data received from the image sensor(s); and a heat management system, which includes:
at least one inlet and at least one outlet in the housing to enable air to flow through the housing;an inlet-side heat sink thermally connected to the image sensor(s), and an outlet-side heat sink thermally connected to the data processing unit(s), said inlet-side heat sink being separated from the outlet-side heat sink; anda fan configured to draw air into the housing through the inlet(s) over the inlet-side heat sink and push air over the outlet-side heat sink out the outlet(s); wherein the fan is a centrifugal fan, such that air is drawn into the front of the fan and pushed out one side of the fan.
