Abstract
A corrugated tube type tube wall type negative pressure vacuum heat tube for a fluid heat exchanger is composed of a corrugated tube type tube wall type structure and a negative pressure vacuum state phase change heat transfer and heat conduction structure. The negative pressure vacuum tube for the fluid heat exchanger is formed by combining the corrugated tube type tube wall type structure and the negative pressure vacuum state phase change heat transfer and heat conduction structure and is novel and efficient.
Description
Technical field
The utility model relates to a kind of for the thermal technology field, fluid heat exchanger node cast tube wall type negative-pressure vacuum heat pipe, it is by having node cast tube wall type structure, form with negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber, especially it has the tube wall type structure of node cast, combine with negative-pressure vacuum phase-change heat transfer heat-conducting structure in tube chamber, the negative-pressure vacuum heat pipe that a kind of novel fluid heat exchanger is used.
Background technology
The utility model has overcome the deficiency that existing heat exchanger is used the negative-pressure vacuum heat pipe, existing negative-pressure vacuum heat pipe is that employing ordinary straight cast structural pipe wall is heat exchange interface, its heat transfer K value is very low, in order to make up this defective so, increased fin structure at its straight tube outer surface, to increase its Heat Conduction thermal efficiency, but because it has increased the fin structure of outer surface of tube wall, easily produce the various heat transfer scale inhibition layers of deposition and be difficult to remove in its use, after use a period of time, its heat transfer efficiency obviously descends.
The utility model content
the purpose of this utility model is achieved through the following technical solutions, it is by having node cast tube wall type structure, form with negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber, a kind of fluid heat exchanger node cast tube wall type negative-pressure vacuum heat pipe, it has negative-pressure vacuum attitude phase-change heat transfer conductive structure in node cast tube wall type structure and tube chamber, especially its outer surface has the tube wall type structure of node cast, has the negative-pressure vacuum heat pipe that a kind of fluid heat exchanger of negative-pressure vacuum attitude phase-change heat transfer structure is used in its tube chamber, replace original straight pipe type tube wall type fin structure with node cast tube wall type structure, its heat absorption efficient Heat Conduction thermal efficiency is obviously improved, because can making fluid, node cast tube wall type structure produces turbulence effect, fluid is become at Reynolds number and the Nu Saier coefficient that wave-node type tube wall type body structure surface flows through, the dynamic equilibrium of heat absorption conductive is moved towards the direction that is more conducive to the efficient raising, thereby its operating efficiency is obviously improved, in addition because it has adopted negative-pressure vacuum phase-change heat transfer heat-conducting structure in tube chamber, make it have negative-pressure vacuum phase-change heat transfer conductive structure in node cast structural pipe wall and tube chamber, the functional structure of the raising Heat Conduction thermal efficiency of stack, in addition due to the surface of node cast tube wall type structure, souring when flow is crossed this surface, make it be not easy to produce heat transfer scale inhibition layer.
Description of drawings
Fig. 1 is a kind of fluid heat exchanger node cast tube wall type negative-pressure vacuum heat pipe front view
Fig. 2 is a kind of fluid heat exchanger node cast tube wall type negative-pressure vacuum heat pipe shaft side figure
In figure, 1. is sealed tube bodies of bulk wave pipe joint type tube wall type structure described in the utility model.
2. be negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber described in the utility model.
The specific embodiment
a kind of fluid heat exchanger described in the utility model is with node cast tube wall type negative-pressure vacuum heat pipe as depicted in figs. 1 and 2, it is the sealed tube body 1 by node cast tube wall type structure, form the moisture functionality structure with negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber 2, its heat absorption efficient Heat Conduction thermal efficiency is obviously improved, because can making fluid, node cast tube wall type structure produces turbulence effect, fluid is become at Reynolds number and the Nu Saier coefficient that wave-node type tube wall type body structure surface flows through, the dynamic equilibrium of heat absorption conductive is moved towards the direction that is more conducive to the efficient raising, thereby its operating efficiency is obviously improved, in addition because it has adopted negative-pressure vacuum phase-change heat transfer heat-conducting structure in tube chamber, make it have negative-pressure vacuum phase-change heat transfer conductive structure in node cast structural pipe wall and tube chamber, the functional structure of the raising Heat Conduction thermal efficiency of stack, in addition due to the surface of node cast tube wall type structure, souring when flow is crossed this surface, make it be not easy to produce heat transfer scale inhibition layer.
Claims (3)
1. a fluid heat exchanger is with node cast tube wall type negative-pressure vacuum heat pipe, it is characterized in that, it is by having node cast tube wall type structure, form with negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber, a kind of fluid heat exchanger negative-pressure vacuum pipe, especially it is to have node cast tube wall type structure, combine with negative-pressure vacuum attitude phase-change heat transfer heat-conducting structure in tube chamber, and have negative-pressure vacuum attitude phase-change heat transfer conductive structure in tube chamber, be applicable to the node cast tube wall type negative-pressure vacuum heat pipe of various fluid heat exchanger.
