The flat sealed casing has one heat absorbing surface and one heat dissipating surface opposite to the heat absorbing surface, and the heat absorbing surface is in contact with one electron heating element, and through the gas-liquid change of the working fluid in the vapor chamber plate, The heat generated by the heat generating parts is transferred from the heat absorbing surface to the heat radiating surface. Since the thermal contact area of the steam chamber plate is relatively large, the distance that the working fluid is advanced is short, so that the heat of the heat is more efficient. Therefore, this steam chamber plate is widely used as a heat sink for LED lighting fixtures.

Since the MOUNTING HOLE is not installed in the flat sealing casing of the steam chamber plate, in order to fix the steam chamber plate at a predetermined position, the flange is extended around the steam chamber plate, and a fixing hole on the flange is provided. Finally, the vapor chamber plate can be fixed in a predetermined position. Therefore, the production cost of the steam chamber plate should be increased, and also, according to the installation conditions, there is a problem that interferes with the principle of mass production by installing different fixing holes.

In addition, the production cost of the steam chamber plate is relatively high, generally speaking, if the steam chamber plate is to be used for the fixed installation of the LED luminaire, a steam chamber plate of a relatively large area must be used. The cost of the apparatus is increased. On the other hand, the thickness of the flat sealing casing of the steam chamber plate is inherently relatively thin, so that if the flange is directly extended from the casing and fixedly installed in a predetermined position, the strength of the entire structure will be remarkably insufficient.

Therefore, how to solve the above-mentioned problems, that is, the goal improved by the present inventors.
