Description
Technical field
The present invention relates to temperature-uniforming plate apparatus fields, and in particular to a kind of hot pressing conversion temperature-uniforming plate.
Background technique
Currently, temperature-uniforming plate is named according to element main feature, had using working fluid in phase change according to it
Latent heat carry out heat transfer to convey the principle of amount of heat, flat plate heat tube can be belonged to, equally principle according to this, can also be by it
Referred to as soaking plate or steam piece etc., the application range of temperature-uniforming plate: the narrow sky severely limited especially suitable for height space
Between radiating requirements in environment.Cooling liquid when temperature-uniforming plate local heating is converted in current hot pressing, in corresponding perforation flow path
Heated heating is limited into cooling liquid not by perforation flow path volume since cooling liquid is filled and is sealed in perforation flow path
Gasification can be generated because temperature increases, can only be increased and hydraulic increase with temperature, generate pressure wave, along cooling liquid transmitting, heat
Amount is transferred to rapidly entire hot pressing from the part of hot pressing conversion temperature-uniforming plate with pressure wave and converts temperature-uniforming plate, and the lasting hot pressing of reality turns
It changes, so that the uniform temperature of hot pressing conversion temperature-uniforming plate is splendid, samming heat exchange efficiency is high.Temperature-uniforming plate is converted in existing hot pressing, inside
Multiple perforation flow paths for being uniformly distributed and penetrating through temperature-uniforming plate body interior are divided into partition, are equipped with deflector hole in partition,
Actual use process forms the laminar flow that high-temperature heating portion is flowed from middle part to sub-cooled portion, and is returned by outer lateral high-temperature heating portion
Stream circulates, and during which liquid flowing is more stable, forms stable laminar flow, the only thermal diffusion between different laminar flows
Effect (thermal diffusion effect diffuser efficiency is solely dependent upon the temperature difference) greatly reduces heat transfer efficiency without thermal convection effect, reduces
Entire heat transfer efficiency.
Number of patent application is the patent document of CN201710191739.9；It is equal that the Chinese invention discloses a kind of hot pressing conversion
Warm plate, radiator temperature uniforming heat radiation method and product, manufacture craft；Temperature-uniforming plate, the temperature-uniforming plate including metal material are converted in the hot pressing
Ontology has the perforation flow path for being uniformly distributed and penetrating through temperature-uniforming plate body interior, the perforation in the temperature-uniforming plate ontology
Cooling liquid is filled in flow path, and cooling liquid is sealed in perforation flow path.Inside with partition be divided into it is multiple be uniformly distributed and
The perforation flow path of temperature-uniforming plate body interior is penetrated through, deflector hole is equipped in partition, practical use process forms high-temperature heating portion
The laminar flow flowed from middle part to sub-cooled portion, and circulating by outer lateral high-temperature heating portion reflux, during which liquid flows
It is more stable, stable laminar flow is formd, entire temperature-uniforming plate heat transfer efficiency is reduced.
Summary of the invention
(1) technical problems to be solved
The object of the present invention is to provide a kind of hot pressing to convert temperature-uniforming plate, by setting buffering return flow line and flow-guiding channel, changes
