In the foregoing operating state, since the vapor channel GC can attract most of the vapor working fluid to flow through, the flow guiding effect on the vapor working fluid can be exerted, so that the vapor working fluid is more easily guided to the vapor channel GC and enters the condensation area C. In addition, since the liquid working fluid flows back from the liquid channel LC to the evaporation area V, the liquid channel LC also exerts a guiding effect on the liquid working fluid, and since the amount of the vapor working fluid between the capillary 17 of the liquid channel LC and the

Referring to fig. 8, a vapor chamber 40 using a wick structure and bumps to form a liquid-vapor channel according to a fourth embodiment of the present invention is substantially the same as the first embodiment, except that:
the first plate 41 has two blocking members 412 located in the heat insulating region a, the two blocking members 412 are pressed against the part of the capillary 47 located in the heat insulating region a corresponding to the liquid channel LC, and the evaporation region V and part of the heat insulating region a are spatially blocked, so that the evaporation region V and part of the heat insulating region a are not spatially communicated. In the fourth embodiment, the two blocking members 412 are in the shape of a boss, and the top surface thereof abuts against the part of the capillary material 47 located in the adiabatic region a, and fills the space between the part of the capillary material 47 located in the adiabatic region a and the first plate 41.
With the above structure, the two blocking members 412 fully block the space between the part of the capillary material 47 located in the heat insulation region a and the first plate 41, so as to block the vapor-state working fluid from passing through, and further force the vapor-state working fluid to flow only through the vapor channel GC while moving from the evaporation region V to the heat insulation region a, and the liquid-state working fluid can flow only through the liquid channel LC. Therefore, the fourth embodiment guides the flow of the liquid and vapor working fluids more simply, and still achieves the effects of the first embodiment.
