Middle-size and small-size commercial cascade refrigeration system (1～6Hp) in environmental test equipment number of applications the most concentrated, once used case tube heat exchanger and double pipe heat exchanger in history, at present the most widely used is the stainless steel braze welding plate type heat exchanger.Case tube heat exchanger is because volume is big, and heat exchange efficiency is low, and the compact heat exchanger little by volume in cascade refrigeration system, that efficient is high replaces; Double-tube heat exchanger is owing to the metal consumption height of unit heat exchange amount, and erection space is big, only uses in the small-sized cascade refrigeration of part at present; And present most popular stainless steel braze welding plate type heat exchanger needs to use the soldering of SUS316L corrosion resistant plate moulding final vacuum to make, and cost is very high.
The utility model content
The purpose of this utility model is to provide a kind of bucket formula heat exchanger with storage liquid function, improves heat exchange efficiency when reducing cost, thereby improves the cost performance of middle-size and small-size cascade refrigeration unit.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The bucket formula heat exchanger that has storage liquid function, comprise outer cylinder body, and the inner barrel that is arranged at outer cylinder body inside, be provided with seal cavity between inner barrel and the outer cylinder body sidewall, in seal cavity, be provided with the multi-head spiral heat exchange coil, be respectively equipped with the gas feed, the liquid outlet that are communicated with seal cavity on the described outer cylinder body, and the evaporator, the evaporator outlet that are communicated with the multi-head spiral heat exchange coil.
Described gas feed, liquid outlet are arranged at the two ends up and down of outer cylinder body sidewall respectively.
Described multi-head spiral heat exchange coil is a spring-like, hovers above on the inner barrel sidewall, and evaporator is connected with multi-head spiral heat exchange coil lower end, and evaporator outlet is connected with multi-head spiral heat exchange coil upper end.
For the adverse current effect of enhanced heat exchange device, increase heat transfer temperature difference, also be provided with spiral deflector in the described seal cavity, spiral deflector hovers above on the inner barrel sidewall according to the trend of multi-head spiral heat exchange coil.
In order to realize the liquid reservoir function, the last bottom surface of described inner barrel all seals, and makes inner barrel form the interior bucket of a sealing.The upper bottom surface of bucket formula heat exchanger then is provided with the heat reservoir outlet with the inner barrel internal communication, and with easy to installation and maintenance, its bottom surface is provided with a heat reservoir import with the inner barrel internal communication.
In addition, for the ease of the installation of heat exchanger, on the bottom surface of outer cylinder body, also be provided with mounting bracket.Outer cylinder body, inner barrel all adopt carbon steel pipe to make, and the multi-head spiral heat exchange coil improves overall price/performance ratio of the present utility model as heat exchanger body greatly.
Operation principle of the present utility model: the gas-liquid mixture after the expansion throttling enters the multi-head spiral heat exchange coil from the evaporator of outer cylinder body side wall lower ends, and the cold-producing medium of HTHP enters seal cavity from the gas feed of outer cylinder body sidewall upper, along with the cold-producing medium of HTHP spirals dirty in seal cavity along spiral deflector, heat is passed to the gas-liquid mixture of multi-head spiral heat exchange coil inside, make its vaporization of being heated, evaporator outlet from the outer cylinder body sidewall upper overflows at last, cold-producing medium in the seal cavity then turns cold behind dissipated heat and flows out from the liquid outlet of outer cylinder body lower end, realizes that finally the heat exchange of two kinds of cold-producing mediums is cold excessively.
Compared with prior art, the beneficial effects of the utility model are: the utility model integrates high temperature level liquid reservoir, subcooler, evaporimeter and low temperature level condenser, compact conformation, when reducing material cost, saved the installing space of refrigeration unit, and improve heat transfer coefficient by the multi-head spiral heat exchange coil, utilize spiral deflector to increase heat transfer temperature difference, thereby improved the heat exchange efficiency of heat exchanger, cost performance is greatly improved.
The utility model is mainly used in commercial cascade refrigeration and (in 1～6Hp) system, has very high practical value.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model.
Fig. 2 is an external structure vertical view of the present utility model.
The specific embodiment
The utility model is described in further detail below by coming in conjunction with the accompanying drawings for example.
As shown in Figure 1 and Figure 2, the bucket formula heat exchanger that has storage liquid function, comprise outer cylinder body 1, and the inner barrel 2 that is arranged at outer cylinder body 1 inside, be provided with seal cavity 6 between inner barrel 2 and outer cylinder body 1 sidewall, in seal cavity 6, be provided with multi-head spiral heat exchange coil 3 and spiral deflector 4, multi-head spiral heat exchange coil 3 is spring-like, hover above on inner barrel 2 sidewalls, spiral deflector 4 moves towards identical with multi-head spiral heat exchange coil 3, also hovers above on inner barrel 2 sidewalls; Two bottom surface complete closed up and down of inner barrel 2 only are provided with a liquid reservoir with internal communication thereon on the bottom surface respectively and export 11 and liquid reservoir import 12; In addition, on outer cylinder body 1, be respectively equipped with the gas feed 7, the liquid outlet 8 that are communicated with seal cavity 6, and the evaporator 9 that is communicated with multi-head spiral heat exchange coil 3, evaporator outlet 10.For the ease of mounting heat exchanger, also be provided with mounting bracket 5 at outer cylinder body 1 bottom surface.
Carrying out heat exchange with R23 and two kinds of cold-producing mediums of R404A, to cross cold be example.When the R23 of HTHP refrigerant gas enters seal cavity 6 between inner/outer tube from gas feed 7, along spiral deflector 4 from up to down with 3 one-tenth counter-current flow of multi-head spiral heat exchange coil, heat transfer temperature difference is maximized, and, flow out from liquid outlet 8 after the R23 heat release condensation the R404A in the heat transferred multi-head spiral heat exchange coil; After the R404A cold-producing medium entered multi-head spiral heat exchange coil 3 by evaporator 9 after the expansion throttling, be heated vaporization and rise along inside pipe wall rotation of gas-liquid mixture was subjected to the R404A gas after the thermal evaporation to overflow heat exchanger from evaporator outlet 10.Behind two kinds of cold-producing medium outflow heat exchangers, the cold heat exchange of mistake has between the two just been finished.
