<p>A thermostatic assembly (c) and a manufacturing method therefor. The thermostatic assembly (c) comprises a metal casing (30), a housing (40), a heat sensitive material (50), a diaphragm (60) and a piston (70).A metal structural body (301) is formed in a chamber (34) of the metal casing (30), and the metal structural body (301) comprises countless granular metal powders (35), and countless cavities (36) mutually communicating with one another.The metal powders (35) are mutually consolidated with one another, and the metal powders (35) located at a peripheral position are mutually consolidated with the inner wall surface (37) of the metal casing (30).The cavities (36) are defined by gaps naturally formed among the metal powders (35), and between the inner wall surface (37) of the metal casing (30) and each adjacent metal powder (35).The heat sensitive material (50) is filled and injected into the cavities (36) in the form of a liquid.Through the design of using an integrally sintered metal structural body (301) and filling the heat sensitive material (50) into the cavities (36), heat conduction efficiency can be greatly improved, thereby shortening the reaction time of the thermostatic assembly (c).</p> |
