Description
Technical field
A kind of finned heat exchanger evaporator is the utility model is related to, is evaporated more particularly, to a kind of double capillary formula fin
Device.
Background technology
Capillary is one of main member in finned heat exchanger refrigeration system, and its function will be handled from condenser
High pressure liquid refrigerant becomes the liquid refrigerant of low pressure by copper pipe throttle expansion valve, is absorbed heat into evaporator evaporation,
Reduce environment temperature.Generally, finned heat exchanger has using single capillary as throttling arrangement in compressor
Under the operating mode of start-stop, system is in unsteady-state heat transfer, is influenceed by the change of condensing pressure and evaporating pressure, single capillary section
The flow of stream has respective change, causes refrigerating speed slow.In addition, if being throttled using single capillary, there is capillary quilt
After blocking, the situation for deficiency of not freezing or freeze just occurs, influences to use.Throttle butterfly is used as using more capillaries are in parallel
Structure, even if after having single capillary to be blocked, other capillaries still can be with normal use, it is achieved thereby that single capillary section
The problem of stream can not freeze after being blocked, reduces maintenance cost.
Utility model content
To achieve the above object, the utility model provides a kind of double capillary formula evaporator fin, using double capillary simultaneously
Connection is used as throttling arrangement, and two coolant channels of formation are non-interference, solve what is do not freezed caused by capillary blockage
Problem, so as to save the cost of after-sales service.Its technical scheme is as described below：
A kind of double capillary formula evaporator fin, including fin, end plate, heat exchanger tube, the evaporator and double capillary collection
It is connected, the double capillary collection is formed by the capillary of parallel connection, and the other end of double capillary collection is connected with device for drying and filtering, institute
State capillary to connect using knockout with device for drying and filtering, capillary is directly connected with evaporator using pants tee joint, and bistrichiasis is thin
Guan Jiyu threeways, knockout are handled using soldering.
The two capillaries length, internal diameter and other physical dimensions are identical, and flow parameter is also consistent.
A kind of double capillary refrigeration system, it is followed successively by compressor, condenser, device for drying and filtering, section that connection forms loop
Device and evaporator are flowed, throttling arrangement, two capillary length, internal diameter and other structure chis are used as by two capillaries are in parallel
Very little identical, flow parameter is also consistent.
The utility model has the following advantages that：
1st, throttle structure is used as using two capillaries are in parallel, solves the product caused by after single capillary blocks
The problem of not freezing or reducing refrigerating capacity, the maintenance rate and repair rate of product are reduced, the reliability of product is improved, has
Considerable cost advantage, there is good market application value.
2. being throttled by the capillary paralleling of two same diameter equal lengths, good refrigeration can be reached, it is real
Now quick cooling.Using the double capillary degree of supercooling in parallel for throttling, adding refrigerant evaporator import, increase refrigerating capacity；It is double
After capillary paralleling throttling enters evaporator, the flow disturbance ability of the liquid in evaporator is added, reduces thermal resistance, improved
The heat exchange efficiency of evaporator, improve the performance of product.

Embodiment
The utility model content is described further with reference to the accompanying drawings and examples.
Double capillary refrigeration system as shown in Figure 1, it is followed successively by connection and forms the compressor in loop, condenser, dried
Filter, throttling arrangement and evaporator, throttling arrangement is used as by two capillaries are in parallel, two capillary length, internal diameter and other
Physical dimension it is identical, flow parameter is also consistent.
As shown in Fig. 2 capillary in parallel forms double capillary collection 5, one end and the device for drying and filtering 7 of double capillary collection 5
Connection, the other end are connected with evaporator, and capillary and device for drying and filtering 7 are connected using red copper knockout 6, capillary and evaporator
Directly connected using pants tee joint, capillary collection is handled with threeway, red copper knockout using soldering.
If the finned evaporator that the utility model is made up of root copper pipe and some aluminum fin-stocks, 1 is fin, and 2 be end plate,
3 be heat exchanger tube, and 4 be manifold trunk (refrigerant exit pipe), and 5 be that (capillary is connected double capillary collection with heat exchanger tube using pants tee joint
Connect), 6 be knockout, and 7 be device for drying and filtering.
The end plate 2 is connected with fin 1, and one end of the heat exchanger tube 3 passes through end plate 2, heat exchanger tube 3 and the phase of manifold trunk 4
Connect, the capillary in double capillary collection 5 is connected with heat exchanger tube 3 using pants tee joint, the double capillary collection 5 and knockout 6
It is connected, the knockout 6 is connected with device for drying and filtering 7.
The utility model product is used as throttle mechanism using two capillaries are in parallel, solves after being blocked because of single capillary
And the problem of causing product not freeze, repair rate and maintenance rate are reduced, and refrigerating capacity is added, improve the heat exchange of evaporator
Efficiency, super performance is improved, there is good market application value.
