Abstract
A kind of evaporation tube of flooded evaporator, belongs to heat exchanger tube preparing technical field.Including body, being formed on the inwall of the body has spiral internal tooth, feature：Being formed successively on the outer wall of body has the first capillary structure layer and the second capillary structure layer, the first capillary structure layer and structure is integrally formed with body, and the second capillary structure layer is integrally formed structure with the first capillary structure layer.There is the second capillary structure layer due to forming to have the first capillary structure layer being combined as a whole with body and form outside the first capillary structure layer on the outer wall of body, thermal contact resistance thus will not be produced between body and first, second capillary structure layer, ensures good heat exchange property；Because first, second capillary structure layer has abundant capillary hole, numerous nucleus of boiling can be produced to improve nucleate boiling and then improve heat transfer coefficient；Because first, second capillary structure layer is made up of thin, blister copper powder particles respectively, dimensional homogeneity is ensured, plays the maximization effect of heat transfer.
Description
Technical field
The utility model belongs to heat exchanger tube preparing technical field, and in particular to a kind of evaporation tube of flooded evaporator.
Background technology
As is known in the industry, liquid is related generally in fields such as refrigeration, Air-conditioning Engineering and energy and power engireerings restraining
The refrigeration system unit and air-conditioning system unit of outer surface evaporation, and mostly used for large-scale central air-conditioning centrifugal chiller
Flooded evaporator.Because copper product has good plasticity, thus full-liquid type evaporation tube is usually using copper pipe.In order to increase
Heat exchange area, the coefficient of heat transfer is improved, generally in a manner of extrusion rolling or welding manner forms fin in copper pipe outer（Custom claims outer
Fin）, and roll out inner fin in copper pipe inwall.
It is no lack of in disclosed patent document and is seen in the example that copper pipe outer forms outer fin with rolling mode, such as
CN1092327C（Heat-transfer tube for mixed refrigerant）、CN2365635Y（Heat-transfer pipe）、CN2539948Y（Interrupted teeth inner thread is seamless
Efficient heat conducting tube）、CN100365369C（Heat exchange tube of evaporator）、CN102425972A（A kind of heat-exchange tube）、
CN103063072（A kind of heat-exchange tube）、CN201034432Y（High finned heat-exchange tube）And CN2740988Y（Heat exchanger is used
Copper and the seamless high finned tube of copper alloy）, etc.；The example such as CN205300349U of fin is formed outside copper pipe with welding manner
（Longitudinal open cell type finned tube）And US2667337（Corrugated pipe with wound fin）, etc..
It is more suited to the example such as CN2911555Y of evaporation tube used as flooded evaporator（Flooded evaporator is used
Evaporation tube）、CN201034436Y（The evaporation heat-transfer pipe of dual reinforcing）、CN101782344B（A kind of two-sided strengthened heat exchange
Pipe）、CN103047891B（The falling film evaporation pipe of netted outer surface）、CN104006579B（A kind of High Efficiency Thermal of evaporator is handed over
Change pipe）And CN105300155A（Evaporation tube）, etc..
And then as is known in the industry, body and fin root can be produced due to forming fin in copper pipe outer with welding manner
（Fin root）Between thermal contact resistance, thus be not exposed to thinking highly of for industry.Existed with rolling mode with mechanical presses processing mode
Copper pipe outer, which forms fin, can eliminate foregoing thermal contact resistance, but obtained fin and the uniformity of groove size can not expire
The expection of sufficient industry, therefore the evaporation tube obtained by extrusion process mode is difficult to embody the maximum of the heat transfer property of full liquid evaporation
Change.
In view of above-mentioned prior art is necessary to be improved, for this, the applicant has made beneficial design and formd down
The technical scheme that face will be introduced.
The content of the invention
Task of the present utility model, which is to provide, a kind of both can eliminate the thermal contact resistance between tube wall and use guarantor
Hinder good heat exchange property, and can tube wall form capillary structure and use ensure it is numerous to produce in use
The nucleus of boiling improves nucleate boiling and then improves heat transfer coefficient, and can also embody good dimensional homogeneity and use performance
The evaporation tube of the flooded evaporator of the maximization effect of heat transfer property.
What task of the present utility model was performed by, a kind of evaporation tube of flooded evaporator, including body, at this
Being formed on the inwall of body has spiral internal tooth, and being characterised by the outer wall of body forming successively has the first capillary structure layer and the
Two capillary structure layers, the first capillary structure layer and are integrally formed structure with body, and the second capillary structure layer and the first capillary knot
Structure layer is integrally formed structure.
In a specific embodiment of the present utility model, the thickness of the first described capillary structure layer is 0.18-
0.22mm, and the thickness of the second described capillary structure layer is 0.38-0.42mm.
In another specific embodiment of the present utility model, first capillary structure layer is sintered by thin copper powder particle
Form, the second described capillary structure layer is made up of blister copper powder particles sintering.
In another specific embodiment of the present utility model, the mesh number of the thin copper powder particle is 800-1000 mesh,
The mesh number of the blister copper powder particles is 300-500 mesh.
In another specific embodiment of the present utility model, described body is copper pipe.
One of technique effect of technical scheme provided by the utility model, have and body due to being formed on the outer wall of body
The first capillary structure layer for being combined as a whole and formed outside the first capillary structure layer and have the second capillary structure layer, thus in pipe
Thermal contact resistance will not be produced between body and first, second capillary structure layer, is able to ensure good heat exchange property；Two, due to
First, second capillary structure layer has abundant capillary hole, thus can produce numerous nucleus of boiling in a state of use
Improve nucleate boiling and then improve heat transfer coefficient；Three, because first, second capillary structure layer is respectively by thin, blister copper powder particles
Form, thus dimensional homogeneity is ensured, can play the maximization effect of heat transfer.
