Abstract
The utility model relates to a fin vacuum phase change heat sinking device used for heating and heat waste utilization. Evaporating sections belong to condensing sections, refrigerating liquid backwards flows into the evaporating sections under the assistance of gravitation, and complex tube cores which are used for providing capillary forces for the backflow of the liquid are needless. Simultaneously, liquid working medium positioned on the inner lower sides of vacuum chambers of the heat sinking devices is provided with fin heating devices. The inside and outside working medium of the heating devices are completely isolated. Because the outer sides of the heat exchanging tubes are provided with the fins, heat exchanging areas are enlarged, and the thermal efficiency is improved. Compared with the prior art, the utility model has the advantages of simple structure, high heating speed, high thermal efficiency, low cost, etc.
Description
The fin type change-vacuum-phase change radiator of a kind of heating and UTILIZATION OF VESIDUAL HEAT IN.
Present change-vacuum-phase change radiator substantially all is to adopt bushing type, promptly in change-vacuum-phase change radiator, runs through totally enclosed heat source tube.Because the volume restrictions of change-vacuum-phase change radiator, the heat source tube diameter that runs through is all too little, so the hot working fluid exchange area in heat pipe and the vacuum radiator is less, and this is must influence change-vacuum-phase change radiator to be rapidly heated.
The utility model is exactly that a kind of heat exchange area that can enlarge thermal source and superconducting working medium will be provided, and improves rate of heat exchange, makes change-vacuum-phase change radiator hot sooner, the method that the thermal efficiency is higher.
The present invention is achieved by the following technical solutions: fin type change-vacuum-phase change radiator bottom is an evaporator section, on the heating tube outer wall that runs through in the evaporator section, be provided with fin formula sheet metal, heating tube two has steam to import and export, heating tube is in the change-vacuum-phase change radiator liquid refrigerant, and the working medium of heating tube inside and outside is isolated fully.
Because adopt such scheme, fin type change-vacuum-phase change radiator structure is also very simple, programming rate, the thermal efficiency have really obtained bigger raising.
Below in conjunction with embodiment shown in the drawings, the utility model is described further:
Accompanying drawing 1: be fin type change-vacuum-phase change radiator structural representation.
Accompanying drawing 2: be fin type change-vacuum-phase change radiator side structure schematic diagram.
Among the figure: (1) condensation segment (2) evaporator section (3) fin heater (4) water, vapour (5) liquid refrigerant (6) gaseous working medium (7) heat radiation wall (8) fin
Accompanying drawing 1 top is that condensation segment (1) bottom is to be provided with fin heater (3) heating liquid refrigerant (5) in the liquid refrigerant of evaporator section (2) evaporator section
The heat energy of accompanying drawing 2 hot water, vapour (4) has enlarged the contact area of heater and working medium (5) because of fin (8) by fin heater (3) heating liquid refrigerant (5), therefore improved rate of heat exchange, heated working medium flashes to gaseous state and moves upward, at condensation segment, behind the thermal discharge along vacuum radiator wall (7), be back in the lower liquid working medium heat absorption evaporation again by the gravity effect.
Claims (1)
1, the fin change-vacuum-phase change radiator of a kind of heating and UTILIZATION OF VESIDUAL HEAT IN is characterized in that: in the radiator vacuum chamber phase-change working substance is housed, the vacuum chamber inner underside is provided with heater, and the inside and outside working medium of heater is isolated fully, and the heater outer wall is provided with the fin that is complementary.
