Refering to what is shown in Fig. 1, refrigerated heat exchanger provided by the embodiment of the utility model, including delivery pump (not shown), compression
Machine (not shown) and heat exchange unit, heat exchange unit include shell 30, the coil pipe 20 in shell 30, casing 10, and
The Heat Conduction Material (not shown) being filled in shell 30, casing 10 include being connected to (not show for conveying external agency with delivery pump
Inner tube 11 out) and the outer tube 12 being sheathed on outside inner tube 11, outer tube 12 is communicated with compressor (not to be shown for conveying refrigerant
Out), inner tube 11 is connected with coil pipe 20.
Refrigerated heat exchanger and refrigeration equipment in the present embodiment is using casing 10 and the concatenated mode of coil pipe 20, external agency
Inner tube 11 and coil pipe 20 are flowed through, cooling can be carried out in two steps, refrigerating speed is faster.Meanwhile refrigerant is located at outer tube 12 and interior
Between pipe 11, Heat Conduction Material is equipped with outside coil pipe 20 and outer tube 12, Heat Conduction Material can carry out hot friendship with outer tube 12 and coil pipe 20
It changes, by the heat transfer of external agency in coil pipe 20 to the refrigerant in outer tube 12, further decreases the temperature of external agency, add
The refrigerating speed of fast external agency.Since refrigerant can reduce the temperature of Heat Conduction Material, and Heat Conduction Material can be by coil pipe 20
The heat absorption of inside and outside medium simultaneously passes to the refrigerant in outer tube 12, improves the heat exchange efficiency of refrigerant, is conducive to drop
The power consumption of low compressor.Delivery pump can flow for external agency provides power, guarantees the flow velocity of external agency, avoids external Jie
Matter condensation, blocking.Wherein, external agency can be beverage or other fluids, and Heat Conduction Material is highly heat-conductive material, have good
Heating conduction can quickly transmit heat.
The coiling of casing 10 is in multi-turn rectangular configuration, and the entrance 111 of inner tube is located at the outside of multi-turn rectangular configuration, and inner tube goes out
Mouth 112 is located at the inside of multi-turn rectangular configuration;The entrance 121 of outer tube is located at 112 side of outlet of inner tube, the outlet 122 of outer tube
Positioned at 111 side of entrance of inner tube;The entrance 111 of inner tube is connected to delivery pump, and the outlet 112 of inner tube is connected to coil pipe 20;Outside
The outlet 122 of pipe is connected to the entrance of compressor, the entrance 121 of outer tube and the outlet of compressor.In the present embodiment, outer tube
External agency flow direction in refrigerant and inner tube 11 in 12 is on the contrary, formation counterflow heat exchange structure, is conducive to improve casing 10
Heat exchange efficiency.Multi-turn rectangular configuration can reduce the volume of casing 10, meanwhile, 10 length of casing is longer, has biggish heat exchange
Area is conducive to refrigerant and exchanges heat with inner tube 11 and Heat Conduction Material.The entrance 121 of outer tube is located at the middle part of rectangular configuration,
The middle portion temperature that will lead to rectangular configuration is low compared with external temperature, the temperature difference on the outside of such 30 external temperature of shell and heat exchange unit
It is small, advantageously reduce the heat exchange of heat exchange unit and external environment.Wherein, refrigerant passes through after the outflow of the outlet of outer tube 122
It condenses, expand after compressor compresses, enter evaporation endothermic in outer tube 12 from the entrance 121 of outer tube, to make the system in outer tube 12
Refrigerant temperature reduces, and plays refrigeration.
The coiling of coil pipe 20 is in multi-turn circular configuration, and the entrance 21 of coil pipe is located at the inside of multi-turn circular configuration, and and inner tube
Outlet 112 be connected to, the outlet 22 of coil pipe is located at the outside of multi-turn circular configuration.In the present embodiment, circular configuration is easily manufactured,
Multi-turn circular configuration has biggish heat exchange area simultaneously.And coil pipe 20 is located at after casing 10, the outside inside coil pipe 20
Medium temperature is lower compared with the external agency temperature in inner tube 11, when it is from the Inside To Outside flowing of circular configuration, due to outer
The refrigerating fluid temperature of side is high compared with the refrigerating fluid temperature of inside, it will causes the outside temperature difference small relative to the inside temperature difference, swaps
Heat it is less, the length that coil pipe 20 is contacted with outer side sleeve 10 can be reduced using circular configuration, save cost.
Coil pipe 20 is stacked and placed on the top of casing 10.In the present embodiment, coil pipe 20 is stacked and placed on 10 top of casing, is conducive to outer tube
Heat transmitting between 12 and coil pipe 20, can reduce the distance of heat transfer, improve rate of heat transfer.
One end that casing 10 is connected with coil pipe 20 is bent straight up, and one end of the entrance of coil pipe 20 is bent straight up,
And the position that casing 10 is connected with coil pipe 20 constitutes "Ji" type structure 13.In the present embodiment, using 13 energy of "Ji" type structure
The enough stress reduced during conveying external agency in pipeline, avoids pipeline from being broken by stress damage.Meanwhile "Ji" type
Structure 13 has certain elasticity, can avoid the stress that 10 junction temperature change expansion of coil pipe 20 and casing/contraction generates.
There is the gap (not shown) for accommodating Heat Conduction Material between coil pipe 20 and/or each circle pipeline of outer tube 12.This implementation
In example, there is the gap for accommodating Heat Conduction Material between each circle pipeline of coil pipe 20, is conducive to the abundant of coil pipe 20 and Heat Conduction Material
Contact increases the heat transfer area of external agency and Heat Conduction Material;Have between each circle pipeline of outer tube 12 and accommodates Heat Conduction Material
Gap, be conducive to coming into full contact with for outer tube 12 and Heat Conduction Material, increase the heat exchange area between Heat Conduction Material and refrigerant.
And then make the fully wrapped around outer tube 12 of Heat Conduction Material and 20 outer wall of coil pipe, it improves between the external agency and refrigerant in coil pipe 20
Exchange rate.
Outer tube 12 is copper pipe, and inner tube 11 and coil pipe 20 are SUS304 material.In the present embodiment, outer tube 12 is had using copper pipe
Preferable heating conduction, convenient for the heat exchange between refrigerant and Heat Conduction Material.Inner tube 11 and coil pipe 20 use SUS304 material,
Corrosion resistance and good, convenient for connecting, and it is safe and healthy.Wherein, SUS304 is 304 stainless steels, pipeline made of the material, defeated
There is good stability, security performance is high when sending food or drink.Further, inner tube 11 and coil pipe 20 can use same
The SUS304 tubing of model is made, caliber and thickness having the same, convenient for the welding of joint, and shrinks and unanimously avoids connector
Place's cooling thermal impact causes joint damaged.It can also be designed to that 20 caliber of coil pipe is greater than 11 caliber of inner tube, work as external agency in this way
Flow velocity reduces after into coil pipe 20, is conducive to the heat exchange efficiency for improving coil pipe 20.
Shell 30 has insulating layer (not shown).In the present embodiment, insulating layer can completely cut off external environment and internal heat
Crosspoint reduces heat exchange unit with environment and exchanges heat.Further, insulating layer constitutes airtight chamber, for accommodating disk
Pipe 20 and casing 10.
