Description
Technical field
The utility model relates to low temperature storage box field, more specifically, it relates to a kind of multi-runner heat exchanging pipe and be coupled
Structure.
Background technique
It needs to come cryo-conservation drug or sample using low temperature storage box in medical industry perhaps laboratory.
In existing low temperature storage box, the heat exchanger tube for being wrapped in inner bladder outer wall is usually single channel.
But in the case where refrigeration system is certain, the pressure loss of heat exchanger tube is difficult to reduce, system COP (refrigeration system
Number, refers to that unit work consumptiom can be obtained cooling capacity, and coefficient of refrigerating performance is big, indicates that refrigeration system efficiency of energy utilization is high) it is difficult to be promoted.
The raising of system COP receives the restriction of single channel heat exchanger tube, this problems demand solves.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of multi-runner heat exchanging pipe and being coupled
Structure has and can reduce heat exchanger tube crushing, improves the advantage of system COP.
To achieve the above object, the utility model provides following technical solution:
A kind of multi-runner heat exchanging pipe parallel-connection structure, including liner, the inner bladder outer wall parallel connection are wound with several heat exchanger tubes.
By using above-mentioned technical proposal, definition single channel refrigerant flow cross-section areas is SCirculation is single, then dual channel freezes
Agent flow cross-section areas SCirculation is double=2SCirculation is single。
The heat exchange area that dual channel and single channel are contacted with inner bladder outer wall respectively answer it is identical, it is assumed herein that contact surface be square
Shape.For single channel, gross area SContact is single=LIt is single* W, herein LIt is singleFor single channel refrigerant circulation overall length, W is the width of rectangle；It is right
In dual channel, section gross area SContact is double=2*LIt is double* W, herein LIt is doubleFor the single circulation overall length of dual channel refrigerant, W is rectangle
It is wide.Because of SContact is single=SContact is double, then, LIt is double=0.5LIt is single。
By upper, SCirculation is double=2SCirculation is single；LIt is double=0.5LIt is single.For dual channel, refrigerant flow cross-section areas increase and each
The refrigerant flow on road is smaller than single channel flow；Each branch pipe range reduces and each branch refrigerant flow is than single channel flow
It is small, so as to advantageously reduce the crushing of heat exchanger tube, improve system COP.
Further, the fin connecting with inner bladder outer wall is provided on the heat exchanger tube.
Further, heat conduction silicone is provided between the heat exchanger tube and inner bladder outer wall.
By using above-mentioned technical proposal, heat conduction silicone can enhance the heat exchange between heat exchanger tube and liner.
Further, several heat exchanger tubes are connected with throttling set.
Further, the throttling set is capillary.
In conclusion the utility model has the following beneficial effects:
1, using the heat exchanger tube of several parallel connections, to reduce heat exchanger tube crushing, system COP is improved；
2, heat conduction silicone is used, to enhance the heat exchange between heat exchanger tube and liner.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of multi-runner heat exchanging pipe parallel-connection structure in embodiment；
Fig. 2 is the structural schematic diagram of capillary and heat exchanger tube in embodiment.
In figure: 1, liner；2, heat exchanger tube；3, capillary.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment:
A kind of multi-runner heat exchanging pipe parallel-connection structure, referring to Fig.1 comprising liner 1,1 outer wall of liner are provided with several heat exchange
Pipe 2, heat exchanger tube 2 is copper pipe in the present embodiment, and the good heat conductivity of copper pipe can enhance heat exchange.
Referring to Fig.1, heat exchanger tube 2 is helically wound around on 1 outer wall of liner, on the one hand can be enhanced between heat exchanger tube 2 and liner 1
Heat exchange, on the other hand can facilitate fixed heat exchanger tube 2；It is provided on heat exchanger tube 2 in the present embodiment and connect with 1 outer wall of liner
Fin (originally attached to be not shown in the figure), so as to enhance the stability that heat exchanger tube 2 is connect with liner 1；Outside heat exchanger tube 2 and liner 1
Wall contact site is coated with heat conduction silicone (originally attached to be not shown in the figure), and heat conduction silicone can further enhance heat exchange.
Referring to Fig.1, several heat exchanger tubes 2 are parallel with one another, then in the case where refrigeration system is certain, in single heat exchanger tube 2
Crushing reduces, and improves system COP.
Referring to Fig. 2, two heat exchanger tubes 2 in parallel are connected with throttling set, and throttling set is capillary 3 in the present embodiment；
Refrigerant is by capillary 3, then respectively enters in two heat exchanger tubes 2, is then return in compressor (originally attached to be not shown in the figure).
Working principle is as follows:
Definition single channel refrigerant flow cross-section areas is SCirculation is single, then dual channel refrigerant flow cross-section areas SCirculation is double=
2SCirculation is single。
The heat exchange area that dual channel and single channel are contacted with 1 outer wall of liner respectively answer it is identical, it is assumed herein that contact surface be square
Shape.For single channel, gross area SContact is single=LIt is single* W, herein LIt is singleFor single channel refrigerant circulation overall length, W is the width of rectangle；It is right
In dual channel, section gross area SContact is double=2*LIt is double* W, herein LIt is doubleFor the single circulation overall length of dual channel refrigerant, W is rectangle
It is wide.Because of SContact is single=SContact is double, then, LIt is double=0.5LIt is single。
By upper, SCirculation is double=2SCirculation is single；LIt is double=0.5LIt is single.For dual channel, refrigerant flow cross-section areas increase and each
The refrigerant flow on road is smaller than single channel flow；Each branch pipe range reduces and each branch refrigerant flow is than single channel flow
It is small, so as to advantageously reduce the crushing of single heat exchanger tube 2, improve system COP.
