Suction Valve Thermal Bridging for High-Pressure Fuel Pumps

A heat-conducting material is introduced as an intermediary between the magnet coil and the hydraulic module. This material serves as a thermal bridge that conducts heat away from the magnet coil to the hydraulic module, which acts as a heat sink due to the continuous flow of cooling fuel through it. This resolves the contradiction by providing a dedicated heat dissipation path without interfering with the magnetic actuation function.

The hydraulic module, through which fuel continuously flows, is utilized as a cooling system. The flowing fuel absorbs heat from the magnet coil via the heat-conducting material, effectively using the hydraulic flow to manage thermal load. This approach converts the hydraulic system into a dual-purpose component: both actuation and cooling.

The heat-conducting material serves multiple functions simultaneously: it acts as a thermal conductor for heat dissipation, a mechanical connector between the magnet coil and hydraulic module, and potentially a sealing element. By combining multiple functions into a single component, the design avoids adding separate elements for each function, thereby limiting the increase in device complexity.

The use of a heat-conducting material represents a composite approach, combining materials with different thermal conductivities to create an optimized thermal management system. The heat-conducting material is integrated into the existing structure, creating a composite assembly that leverages the thermal properties of the added material while maintaining the structural integrity of the original components.
