Fig. 1 is this utility model absorption refrigeration unit external structure and the built-in solution heat exchanger installation site schematic diagram at absorption refrigeration unit.
Being illustrated in figure 1 lithium bromide absorbing type refrigeration unit 100, it is rectangular structure, and inside is provided with the heat-exchanging part (not shown)s such as regenerator, vaporizer, absorber, condenser.Lithium bromide absorbing type refrigeration unit is with lithium-bromide solution+pure water for working medium pair, and wherein pure water is chilled water, and lithium-bromide solution is absorbing liquid；Pure water evaporation endothermic in vaporizer realizes refrigerating function.Refrigerant vapor is become after chilled water heat absorption evaporation.In absorber, refrigerant vapor is brominated lithium solution and absorbs the part becoming solution, is pumped into regenerator together along with lithium-bromide solution.In a regenerator, chilled water is with solution thermal regeneration, and chilled water evaporates from solution and again becomes gaseous state.Then, refrigerant vapor is condensed and becomes liquid within the condenser.Again become the chilled water of liquid to return to vaporizer and again absorb heat evaporation.Through chilled water from the decalescence of liquid gaseous, liquid, carry out kind of refrigeration cycle endlessly.Wherein cold water, hot water and cooling water flow at vaporizer, regenerator, absorber and condenser each heat exchanger tube side to carry out heat exchange.Thus, refrigeration unit 100 surface is provided with multiple cold water, hot water and cooling water access interface 105 being interconnected with extraneous (thermal source, refrigeration duty etc.)；Cooling water required for the extraneous hot water by these interfaces 105 required for the refrigeration unit supply regenerator, the cold water required for vaporizer, and absorber and condenser.
In above-mentioned cooling flow, owing to lithium bromide weak solution has been cooled water cooling in absorber, temperature is relatively low, simultaneously, the concentrated solution temperature flowed out from generator is higher, in order to save heat and the cold of cooling concentrated solution of heat dilute solution, improve the thermal efficiency of whole device, add a solution heat exchanger in systems, device shown in rectangular area, absorption refrigeration unit side 120 in i.e. Fig. 1, the low temperature weak solution that the high temperature concentrated solution that solution heat exchanger flows out by generator flows out with absorber carries out heat exchange, the temperature that can improve weak solution entrance generator also can reduce the temperature of concentrated solution entrance absorber.
In Fig. 1, solution heat exchanger 205 is arranged on absorption refrigeration unit lateral inner, and outside is connected as a single entity with absorption refrigeration unit.The outside (Fig. 2 B is seen in inboard) of the heat exchange wallboard 220 for solution heat exchanger 120 shown in rectangular area；Solution heat exchanger 120 internal structure is shown in Fig. 2 A.
Fig. 2 A is solution heat exchanger of the present utility model and solution channel structural representation.
Solution heat exchanger 205 is the body structure that a rectangle is the most flat, and its inside polylith heat exchange wallboard (see 220 in Fig. 2 B) arranges at uniform intervals, forms multiple solution channel, weak solution passage 212 the most spaced apart from each other and concentrated solution passage 214.Weak solution passage 212 and concentrated solution passage 214 cooperatively form airtight heat transfer space with heat exchange wallboard 220, the weak solution of low temperature contacts with heat exchange wallboard 220 with the concentrated solution of high temperature simultaneously, and heat exchange wallboard 220 becomes the weak solution of low temperature and the medium of the concentrated solution heat exchange of high temperature.The gateway of solution channel is further respectively had, respectively: the concentrated solution entrance 206 in the upper left corner, the weak solution entrance 201 in the lower left corner, the weak solution outlet 208 in the upper right corner and the concentrated solution outlet 202 in the lower right corner on four angles of solution heat exchanger 205.
Enter from the entrance 201 in the lower left corner from solution pump 203 weak solution out, the weak solution passage 212 in solution heat exchanger 205, deliver to the outlet 208 in the upper right corner, then lead to generator through passage 209, connector 210.
Meanwhile, the concentrated solution returned from generator enters solution heat exchanger 205 from entrance 206, the concentrated solution passage 214 in solution heat exchanger 205, flow to export 202, then leads to absorber through passage 204, connector 207.
Fig. 2 B is the internal structure schematic diagram of solution heat exchanger body of the present utility model；Fig. 2 C is the cross-sectional view in Fig. 2 B along line C-C
As shown in Fig. 2 B, 2C, heat exchange wallboard 220 is the rectangle that shape is identical with solution heat exchanger 205, it is stamped to form through cold-press process for corrosion resistant plate, it is stamped and formed out some the most alternate intensive raised lines 222 on an internal surface, for supporting heat exchange wallboard to bear vacuum pressure, and the fluid flowing through raised line is made to produce turbulent flow to improve heat transfer coefficient.
Fig. 3 A, 3B are the gasket construction schematic diagrams of solution heat exchanger 205 of the present utility model；
Multiple airtight fluid heat transfer passages are formed in the solution heat exchanger 205 shown in Fig. 2 C, Multi-layer exchanging heat wallboard 220 and packing ring 300 combination.
As shown in Fig. 3 A, 3B, packing ring 300 is the rectangle 304 and 308 being provided with two circular seal on the diagonal, and the position of the circular seal in adjacent two passages is just the opposite；Such as circular seal 304 position at previous passage is the upper left corner and the lower right corner, and the position of the circular seal 308 of another passage the most adjacent thereto is the upper right corner and the lower left corner.Circular seal 304 blocks two ports in the upper left corner and the lower right corner, is also turned on two ports in the lower left corner and the upper right corner；In contrast, circular seal 308 connects two ports in the upper left corner and the lower right corner, blocks two ports in the lower left corner and the upper right corner simultaneously.It is arranged so as to, forms cold and hot fluid multiple passages spaced apart from each other in solution heat exchanger 205, Multi-layer exchanging heat wallboard 220 form heat-transfer surface, add heat exchange area.
The diagonal passage that flow channel 212 is the rectangle flowed to the upper right corner 208 from the lower left corner 201 of cold flow body (weak solution) in solution heat exchanger, due to the blocking-up of the circular seal 304 on the packing ring 300 in Fig. 3, cold flow body will not flow to the port in the upper left corner or the lower right corner.
The diagonal passage that flow channel 214 is the rectangle flowed to the lower right corner 202 from the upper left corner 206 of hot fluid (concentrated solution) in heat exchanger, due to the blocking-up of the circular seal 308 on the packing ring 300 in Fig. 3, cold flow body will not flow to the port in the lower left corner or the upper right corner.
Additionally, the body of solution heat exchanger 205 of the present utility model selects engineering plastics；The preferable corrosion resistant plate of corrosion resistance selected by heat exchange wallboard 220.The very thin thickness of solution heat exchanger 205, can secretly be embedded in the fuselage side wall of absorption refrigeration unit, become a part for fuselage, while completing heat exchange function, may also function as alleviating fuselage weight, the effect of reinforcement fuselage intensity on cross sectional shape.
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, the built-in solution heat exchanger of absorption refrigeration unit of the present utility model and use described solution heat exchanger absorption refrigeration unit and refrigeration matrix can have many versions.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.
