Technical field
The present invention relates to a kind of condenser, in particular to a kind of lattice structure condenser manufactured using 3D printing technique.
Background technique
Heat exchanger is the key equipment of reasonable energy utilization.In field of heat exchange, without phase-change when heat exchanger only consider that sensible heat is handed over
It changes, the temperature difference is the motive force of heat exchange；And there are when phase transformation, the latent heat that fluid phase change generates is very big, i.e., steam condenses
Heat release is than high more of single-phase heat exchange load.Therefore great to the research significance of phase-change heat-exchange.Phase-change heat-exchange is in aerospace, space
There is many use and development in the fields such as detection, infrared, atomic energy, superconduction.Loop heat pipe is a kind of efficient, passive type two-phase
Heat exchange equipment, evaporator and condenser are connected by pipeline flexible, meet the requirement of various space layouts, realize the length of cooling capacity away from
From transport, and additional energy, movement-less part are not needed.
The design of condenser will be convenient for coupling with cold source, while need to strengthen its exchange capability of heat, reduces running resistance.It is right at present
In loop heat pipe, common condenser structure is serpentine coil condenser and micro-channel condenser, serpentine coil condenser structure
Simple handling ease, but there is a problem of that size is big, quality is big, thermal resistance is big.Micro-channel condenser heat exchange efficiency is high, light weight,
But running resistance is larger, is unfavorable for system starting operation.
Various countries more concentrate on the research of internal manifold and heat transfer intensity relationship, coagulate in the research of condenser at present
Influence and the condensation test coefficient of heat transfer of the research, close and distant water surface of knot mode and heat transfer intensity relationship to condensation mode and
The empirical equation of pressure drop is fitted.The final purpose of these researchs, which is provided to find out, promotes the condenser coefficient of heat transfer, reduces disengaging
The factor of mouth pressure drop realizes high-intensitive heat exchange to make condenser under small system running resistance.
Summary of the invention
The purpose of the present invention is: low in order to solve the existing condenser coefficient of heat transfer, size is big, quality is big, thermal resistance is big, operation
The problems such as resistance is big provides a kind of novel lattice structure condensing unit, which not only can increase heat exchange area, increases heat exchange
Amount can also reduce inlet and outlet pressure drop, reduce system running resistance.Present invention process is integrally completed using 3D printing technique, is protected
It has demonstrate,proved the air-tightness of inner cavity and has reduced the thermal contact resistance of the generations such as welding.
A kind of lattice structure condenser manufactured using 3D printing technique of the present invention, it includes cavity 1, ribs 2, dot matrix
Structure 3, air inlet 4, liquid outlet 5, condensation working face 6, connection screw thread hole 7.
It is whole to be completed using 3D printing technique in the lattice structure condenser, select aluminum alloy materials.Cavity 1 is
Hollow rectangular parallelepiped structure, cavity are supported rib 2 and divide for three parts, the full lattice structure 3 of cavity hollow space filling, the cavity upper left corner
Air inlet pipe 4 is printed, the cavity lower right corner prints outlet tube 5, and condensation working face 6 is connect with the external world by connection screw thread hole 7.
The cavity hollow space is filled full lattice structure and is integrally printed with cavity by 3D printing technique, dot matrix knot
Structure is the body unit lattice that line is linked to be, and middle section is empty, so that working medium passes through, cell and cavity top and bottom and side pass through list
Together, cell size dimension can be modified according to inside cavity size and heat exchange amount demand for cable architecture growth on first lattice
Design.
The ribs are located at the position of condenser 1/3 and 2/3, and do not fill up cavity, and there are the mouths that working medium passes through.
For ribs close to air inlet above, the ribs close to liquid outlet are below.Ribs will be divided into three inside condenser
Point, the S-type arrangement of runner, the ribs have support cavity effect, meet 4Mpa or less high pressure operations.Have simultaneously and leads
Stream effect, passes through condenser for working medium with S-shaped water conservancy diversion.
1 upper left corner air inlet 4 of cavity is round tube, and is relatively large in diameter.1 lower right corner liquid outlet 5 of cavity is round tube, and
Diameter is smaller,.Air inlet and liquid outlet round tube internal-and external diameter can be modified design according to practical situations.
The specific work process of the lattice structure condenser is as follows:
The condenser condensation working face 6 be coupled by threaded hole 7 with cold source, gaseous working medium with certain pressure,
Flow from the condenser air inlet 4 flow into, full of lattice structure 3 cavity 1 in sufficiently with lattice structure and inner cavity wall surface
Carry out heat exchange, the three small cavitys dividing of ribs 2 successively passed through with S-shaped, guarantee time of contact of working medium and condenser with
Area realizes the condensation of gaseous state to liquid.Working medium after phase transformation is flowed out in the form of liquid from condenser liquid outlet 5, with cold
Amount enters circulating liquid pipeline, realizes the transfer of cooling capacity.
The present invention compared with existing condenser, the advantage is that:
1. lattice structure increases the contact area between fluid and wall surface, while fluid flow has perturbation action, increases
Strongly heat exchange between the two is conducive to the progress of condensing heat-exchange.
2. lattice structure compares micro-channel type condenser, there is good permeability, it is ensured that on the basis of heat transfer intensity,
The pressure drop for effectively weakening inlet and outlet, reduces system running resistance.Simultaneously 3D printing can be adjusted according to different working medium difference operating conditions
When lattice structure density degree, to realize optimal heat exchange amount and the smallest pressure drop.
3. processing technology of the present invention is realized by 3D entirety printing technique, it ensure that the air-tightness of internal cavity, keep away simultaneously
The thermal contact resistance generated when having exempted from general condenser using welding procedure.
4. support rib structure had both realized the supporting role of lattice structure, the operating pressure of 4Mpa high pressure can be born.Simultaneously
Guiding function is risen to the flowing of fluid in the lumen, guarantees that fluid and cavity come into full contact with area and time.
5. big air inlet reduces the resistance of fluid operation, small liquid outlet ensure that the flexibility of pipeline.
