Abstract
To achieve reductions in size and weight and a higher functionality of an imaging device, the imaging device comprises a first circuit board mounting a first heat-generating component for processing a signal from the imaging sensor, a first heat dissipation plate for transferring heat from the first heat-generating component to the housing; and a fan disposed adjacent to the first heat dissipation plate, air-cooling the first heat dissipation plate, wherein the fan is configured to take in the air in a rotation axis direction and discharges the air in an outer circumferential direction, and the discharged air is blown to heat dissipation fins of the heat sink of the first heat dissipation plate and discharged from the discharge port.
Claims7
An imaging device comprising:
- a housing including an intake port and a discharge port and at least partially made up of a heat dissipation member;
- an imaging sensor for converting light into an electrical signal disposed inside the housing;
- a first circuit board disposed inside the housing and on which a first heat-generating component for processing a signal from the imaging sensor is mounted;
- a first heat dissipation plate for transferring heat from the first heat-generating component to the housing;
- and
- a fan disposed adjacent to the first heat dissipation plate, taking in outside air through the intake port, air-cooling the first heat dissipation plate with the taken-in outside air, and blowing out the air from the discharge port, wherein
- the first heat dissipation plate is provided with a heat sink,
- the fan takes in the air in a rotation axis direction and discharges the air in an outer circumferential direction, and wherein the discharged air is blown to heat dissipation fins of the heat sink and discharged from the discharge port,
- the intake port, a fan discharge port of the fan, the heat dissipation fins of the heat sink, and the discharge port are linearly arranged in a direction orthogonal to the rotation axis of the fan inside the housing so that the air taken in from the intake port is linearly discharged toward the discharge port, and
- the fan and the heat sink do not overlap in the rotation axis direction.
