Fully sealed structure and heat transfer technology

HF radar in the marine environment, conditions, vulnerable to salt spray corrosion , in order to meet the reliability , environmental compatibility , electromagnetic compatibility and other military standard requirements, according to the Navy for many years engaged in product design experience , in addition to the circuit board components in strict accordance with the three anti- design, all parts corrosion-resistant materials and surface corrosion treatment outside the main chassis and the radar transmitter enclosure with fully luggage seals sealed structure to achieve environmental adaptability requirements of each circuit boards and modules between the use of isolation and shielding design to prevent electromagnetic leakage and interference , to ensure electromagnetic compatibility requirements in order to improve product quality and reliability.

Radar hosts and transmitters with full sealing mechanism , the electronic components and power supply has sealed all the heat inside the chassis , in order to ensure long-term work , using a fully sealed structure and heat transfer technology . The main core techniques are as follows : 1. Reed heat conduction technology special design on the chassis of the thermal conductor , to ensure the direct heat conduction. Thermal conductivity of the circuit module rail mounting , as well as ensure that the entire thermal conductivity is not over-temperature , thermal conductivity is fixed between the left and right rails , the thermal control of heat transfer to the rail and then spread to the heat sink can be through a dedicated duct heat away , the use of reed -type heat transfer technology, using high thermal conductivity of the material , made of highly wear-resistant elastic reed , fixed on the rail , while using the self- locking device , making the skills to achieve locking , can slide smoothly on the rail . 2 Sealed balanced cooling technology radar transmitters and radar host chassis is completely sealed by the internal fan and return air duct to the various hot spots scattered in the heat balance inside a pull tite seals sealed chamber , and then rely on thermal radiation and convection the heat conduction in the entire housing , the housing of the chassis has a heat sink and convection heat axial fan speed , so as to achieve the purpose of external cooling equipment housing .
