Abstract
Ventilated heat shields and methods are disclosed. The ventilated heat shield can use varying patterns of insulating material with ventilation regions arranged in one or more two-dimensional (2D) and/or three-dimensional (3D) patterns to provide thermal insulation and air channels that allow for dissipation of heat and the inflow of cooling air. The ventilated heat shield can be used in applications where two surfaces are required to be in very close proximity or contact with each other to reduce the transfer of heat from one surface to the other. An example application for the ventilated heat shield is in a vehicle braking system.
Claims17
An apparatus, comprising:
- a brake pad;
- a piston;
- and
- a heat shield, made of a material and comprising a pattern of one or more ventilation regions,
- wherein the heat shield is configured to be placed between the brake pad and the piston to reduce transfer of heat from at least a portion of a surface of the brake pad to a surface of the piston at least by insulation and air flow, the air flow directed by the pattern of the one or more ventilation regions away from the portion of the brake pad,
- wherein the heat shield comprises a plurality of layers, wherein at least one layer of the heat shield is configured with at least one ventilation region of the one or more ventilation regions, wherein a first layer of the plurality of layers comprises a first pattern of ventilation regions, and wherein a second layer of the plurality of layers comprises a second pattern of ventilation regions that differs from the first pattern.
A method, comprising:
- inserting a heat shield between a heat source surface of a device and a contact surface of the device, the heat shield made of a material;
- and
- transferring heat from the heat source surface of the device away from the contact surface at least via insulation by the heat shield and via flow of air directed through a pattern of one or more ventilation regions of the heat shield,
- wherein the heat shield comprises a plurality of layers, wherein at least one layer of the heat shield is configured with at least one ventilation region of the one or more ventilation regions, wherein a first layer of the plurality of layers comprises a first pattern of ventilation regions, and wherein a second layer of the plurality of layers comprises a second pattern of ventilation regions that differs from the first pattern.
