Problems solved by technology

However, in this solution, the design of the housing structure is relatively complicated, and the volume is large, and the system air duct resistance is relatively large. In order to meet the heat dissipation requirements, a larger and thicker fan has to be selected, which further leads to the overall size of the projector. Increased, and at the same time brought a larger noise

Abstract

The invention provides a radiator which is used for a safety processing module and is arranged in an internal space of the safety processing module so as to radiate the internal space of the safety processing module. The radiator comprises radiating fins, and each radiating fin comprises a radiating fin body and a blocking structure which is connected with the radiating fin body and used for blocking external detection of the safety processing module. The invention also provides a safety processing module and a projector using the radiator. Compared with the prior art, the radiator, the safety processing module and the projector are good in ventilation condition, good in system heat dissipation performance and low in noise.

Description

【Technical field】 [0001] The invention relates to the technical field of projectors, in particular to a radiator, a safety processing module and a projector. 【Background technique】 [0002] An important part of the projector is a secure processing block (Secure Processing Block, SPB for short). The secure processing module has a physical protection boundary, which can prevent access and detection of its internal circuits, thereby providing physical protection for internal security entities. [0003] In order to dissipate heat from devices inside the security processing module, a heat sink is usually provided in its inner space. In order to meet the purpose of anti-access detection of the security processing module, some projectors cover the casing of the security processing module arranged on the periphery of the radiator as a labyrinth structure. The labyrinth structure can block the line of sight, and the observer cannot see the internal components of the projector witho...
