Abstract
The invention discloses a boiling heat exchanger outside an ultrasonic oscillating tube and provides a heat exchanger capable of improving the escape velocity of gas on the wall of a heat exchanger tube through oscillation and enhancing the boiling heat exchanging effect. The boiling heat exchanger outside the ultrasonic oscillating tube comprises a shell and a heat exchanger tube, wherein the shell is provided with a liquid supply tube, a gas return tube, a secondary refrigerant inlet nozzle and a secondary refrigerant outlet nozzle, the gas return tube and the liquid supply tube are respectively welded in corresponding positions at the upper end and the lower end of the shell, and an ultrasonic oscillating rod is arranged on the shell at the lower end of the heat exchanger tube and connected with an ultrasonic generator mounted outside the shell through a high-frequency line. In the invention, refrigerant liquid in a space outside the tube is oscillated by utilizing the ultrasonic oscillating rod, and a large amount of bubbles generated on the surface outside the tube are rapidly separated from the wall face and move in the liquid so that the aggregation of bubbles are effectively prevented and the formed gas rapidly escapes from the liquid, and thus, the boiling heat exchanging effect is enhanced, the heat exchanging coefficient is improved, metal materials are saved, the equipment weight is lightened, the equipment cost is decreased, and the purposes of saving energy and protecting the environment are achieved.
Description
Technical field
The present invention relates to the outer boiling heat exchanger of a kind of sonic oscillation pipe.
Background technology
Flooded evaporator in the refrigeration system is a horizontal shell and tube type, in the cylindrical shell of flooded evaporator, fill liquid refrigerant, liquid contacts with heating surface well, the boiling heat transfer coefficient height, but it need charge into a large amount of cold-producing mediums, fill and highly be generally 55%~80%, the characteristic difference of refrigeration working medium fills highly different.In the use, refrigerating medium flows in heat-transfer pipe, and liquid refrigerant is in pipe external space evaporation boiling, and minute bubbles a large amount of in the refrigerant liquid generate, break away from wall, the growth of bubble and effusion are brought out liquid and are involved in diabatic process, take away heat simultaneously in liquid internal motion, agitated liquid.If increase bubble effusion speed, then can quicken the stirring of bubble, increase the surface area of gas-liquid contact greatly; strengthen the boiling heat transfer effect; improve the coefficient of heat transfer, under the condition that satisfies identical heat exchange amount, can reduce the size of flooded evaporator; save metal consumption; reduce the charging amount of liquid refrigerant, reduce operating cost, energy savings; protect environment, satisfy the demand of different refrigeration working medium refrigeration systems.But there is not the researcher to propose the concrete technical scheme of implementing at present.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, a kind of effusion speed by gas on the vibration raising heat exchange tube wall to be provided, strengthening the outer boiling heat exchanger of sonic oscillation pipe of boiling heat transfer effect.
The present invention is achieved through the following technical solutions:
The outer boiling heat exchanger of a kind of sonic oscillation pipe, comprise housing and heat exchanger tube, described housing is provided with feed pipe, muffler, refrigerating medium import and refrigerating medium outlet, it is characterized in that, described muffler and feed pipe are welded on the position of housing top and bottom correspondence respectively, in the housing of described heat exchanger tube lower end the sonic oscillation rod is installed, described sonic oscillation rod is connected by high-frequency line with the ultrasonic generator that is installed in hull outside.
Described heat exchanger tube is made up of parent tube and porous outer surface layer.
