Abstract
The invention relates to the field of optoelectronics. In order to fix heat conduction pipes and heat dissipation sheets in a radiator, the invention provides a heat pipe type heat dissipation module and an optical machine module using the same. The heat pipe type heat dissipation module comprises the heat conduction pipes, heat absorption components and heat dissipation components. Each heat conduction pipe comprises a heat absorption end and a condensation end. The heat absorption components are arranged on the heat absorption ends. The heat dissipation components are arranged on the condensation ends. Each heat absorption component is formed by combining a number of heat dissipation sheets. The heat dissipation sheets and the heat conduction pipes are fixedly connected through a riveting tight matching process. The heat absorption components are inserted in the optical machine module. The heat dissipation components are located outside the optical machine module. After heat generated by an operating fluorescent wheel in the optical machine module reaches the heat absorption components, heat is transmitted to the heat dissipation components outside the optical machine module through the heat conduction pipes, so that the heat of the fluorescent wheel is reliably dissipated. Due to the fact that the riveting tight matching process rather than soldering is used for the heat absorption components and the heat conduction pipes, the fluorescent wheel is not polluted by the heat absorption components.
Description
Technical field
The present invention relates to photoelectric field, particularly relate to heat pipe type heat radiation module and use the bare engine module of this heat radiation module.
