Detailed description of the invention
Accompanying drawing constitutes the part of this specification；Below with reference to the accompanying drawings various detailed description of the invention of the present utility model are described.It should be appreciated that, for convenience of explanation, this utility model employs the term representing direction, such as "front", "rear", " on ", D score, "left", "right" etc. various example features of the present utility model and element are described, but these direction terms are only to determine according to example orientations shown in accompanying drawing.Owing to embodiment disclosed in the utility model can be arranged according to different directions, so these represent that the term in direction is intended only as explanation and should not be considered as limiting.In the conceived case, the identical or similar reference used in this utility model, refer to identical parts.
Fig. 1 is the viewgraph of cross-section of this utility model inclined-plane water conservancy diversion condenser and the generator architecture of side.
It is illustrated in figure 1 the vitals of absorption refrigeration unit: the generator 101 in left side and the condenser 103 on right side, centre is ramp type liquid islocation plate 102.
Require supplementation with explanation: the effect of left side generator 101 is lithium bromide weak solution to be heated, make the chilled water absorbed in weak solution constantly vaporize and become refrigerant vapor, condenser 103 on the right side of refrigerant vapor entrance condenses after meeting cold cooling, becomes the liquid refrigerants water of high pressure low temperature；When the chilled water in condenser 103 enters the vaporizer of refrigeration unit by throttle orifice, absorb the heat of the cold water of the interior flowing of vaporizer tube sides in a large number and vaporize, thus reach to the purpose of cold water cooling refrigeration.The effect of condenser 103 of the present utility model is i.e. the refrigerant vapor that regenerator produces to be carried out cooling condense, and becomes chilled water.
As shown in Figure 1 and Figure 2, condenser 103 includes multiple rows of heat exchanger tube 110,112 (illustrate only part heat exchanger tube in figure) and guiding gutter 114,116.
Heat exchanger tube 110,112 arranges in levels；In heat exchanger tube 110,112, circulation has cooling water, for the refrigerant vapor cooling condensation entered in condenser 103.Being respectively equipped with guiding gutter 114,116 under heat exchanger tube 110,112, guiding gutter 114,116 is rectangular shallow slot (see Fig. 2, Fig. 3).Refrigerant vapor forms little water droplet after the cooled liquefaction in heat exchanger tube 110,112 surface；Little water droplet constantly collects and falls diversed groove 114,116 and collect and derive, it is to avoid water droplet continues to drop onto lower section and respectively arranges heat exchanger tube, thus prevents from being formed continuous moisture film on the heat exchanger tube surface of lower section, reduces the heat transmission resistance between steam and heat exchanger tube.
Guiding gutter 114,116 is parallel with heat exchanger tube 110,112, and all horizontal by the inclination angle of about 10 °, the chilled water Accelerating Removal under gravity that this inclination angle is collected in being conducive to guiding gutter 114,116.
Ramp type liquid islocation plate 102 is arranged on a higher lateral edges of guiding gutter 114,116, is used for retaining the drop carried secretly in the coolant steam that left side generator 101 heating evaporation produces, and only allows coolant steam to cross the condenser 103 on the right side of ramp type liquid islocation plate 102 entrance.
Fig. 2 is the structural perspective of this utility model inclined-plane water conservancy diversion condenser.
As shown in Figure 2, it is 45 ° of support bars 205 to 135 ° of angles that the bottom land of upper strata guiding gutter 114 is provided with guiding gutter 114 edge, the effect of support bar 205 is to support top heat exchanger tube, and makes to be formed between the bottom land of heat exchanger tube and guiding gutter 114 gap, facilitates the condensed water of bottom land quickly to flow out.
Additionally, as an embodiment, be provided with 10 drainage holes 206 along lowest part under the bottom land of guiding gutter 114, condensation flow, through described guiding gutter 114 bottom land, flows out through support bar 205 water conservancy diversion and from drainage hole 206.
Fig. 3 is the structural blast figure of this utility model inclined-plane water conservancy diversion condenser.
As it is shown on figure 3, upper row's guiding gutter 114 and lower row's guiding gutter 116 have been opened a segment distance, two pieces of guiding gutters be arranged in parallel, and the angle tilted is identical.Upper row's guiding gutter 114 edge 10 drainage holes 206 align under 10 drainage holes 308 (part drainage hole is blocked by the upper row's guiding gutter 114) in the vertical direction at lower floor's guiding gutter 116 edge, when making condensed water drain under gravity, current in the drainage hole of upper strata directly flow through from lower floor's drainage hole of alignment, and the earial drainage between two rows guiding gutter is the most interference-free.
In addition, in this utility model, the external diameter of heat exchanger tube 110 is 2.5-3.5mm, and described in two rows, the shortest distance of center circle of heat exchanger tube 110 is 7mm, and the distance of center circle of the adjacent described heat exchanger tube 110 of same row is 4mm, so dense arrangement, obtains high heat transfer area in unit volume.Guiding gutter is all made up of engineering plastics, and its density is little, lightweight, beneficially refrigeration unit miniaturization.Heat exchanger tube is made of stainless steel.
Although this utility model will be described with reference to the detailed description of the invention shown in accompanying drawing, it is to be understood that, under the spirit instructed without departing substantially from this utility model, scope and background, inclined-plane of the present utility model water conservancy diversion condenser and the absorption refrigeration unit of this inclined-plane water conservancy diversion condenser of employing and refrigeration matrix can have many versions, the size at such as angle of inclination and heat exchanger tube and the change of distance, etc..In art technology, those of ordinary skill will additionally appreciate different modes to the parameter changing in embodiment disclosed in the utility model, size, but this each falls within this utility model and spirit and scope by the claims.
