Description
Technical field
The utility model relates to a kind of automotive air-conditioning system, specifically a kind of coaxitron of automotive air-conditioning system, belongs to automotive air-conditioning system technical field.
Background technique
Car air conditioner adopts the power of motor to regulate air in a car compartment environment for cost.Car air conditioner is run efficiently, just requires that its refrigerating capacity is large especially, thus substantially increase engine workload, the coefficients such as oil consumption are improved greatly.General refrigeration pipe cannot accomplish to make full use of the refrigerating capacity that vehicle produces in the process of moving, so need to improve car air conditioner heat-exchange tube line structure, thus reduces the oil consumption of automobile in running, energy saving.In car air conditioner industry, in order to conserve space, improve refrigeration, bring into use coaxial heat-exchange tube, the design proposal of the coaxitron of prior art is mainly in the middle of coaxial inside and outside Al-alloy pipe and forms vertical passage, and the fluid be beneficial in this interchannel fluid and interior pipe carries out heat exchange.But along with the requirement of automotive light weight technology, the efficiency of heat exchange is had higher requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thus provides a kind of coaxitron of automotive air-conditioning system, by increasing heat exchange area, improves the heat exchange efficiency of car air conditioner.
According to the technological scheme that the utility model provides, a kind of coaxitron of automotive air-conditioning system comprises outer tube body and interior tube body, interior tube body is positioned at outer tube body, it is characterized in that: the madial wall of outer tube body is provided with multiple inwardly protruded outer tube body tooth, multiple outer tube body tooth front ends cooperating contact interior tube body, thus firm support interior tube body; The madial wall of described outer tube body, between multiple outer tube body tooth and interior tube body outer side wall, form multiple separated outer fluid cavity; Be provided with inner fluid cavity inside interior tube body, the madial wall of interior tube body is provided with multiple interior tube body thermal trough.
Further, multiple outer tube body tooth is uniformly distributed along outer tube body circumferencial direction.
Further, multiple interior tube body thermal trough along the circumferential direction distributes twist.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, arranges outer tube body tooth at outer tube body madial wall, and outer fluid cavity uses as the passage of the external fluid of heat exchange, and meanwhile, multiple outer fluid cavity is separated and can be improved heat exchange effect; Interior tube body madial wall arranges interior tube body thermal trough, and the internal flow in inner fluid cavity forms helical flow when flowing, and increases the contact heat-exchanging area of cavity fluid and interior pipe, improves heat exchange efficiency; The spiral chute quantity of interior tube body inwall is more, and heat exchange area is larger, and heat exchange effect is better.

Fig. 2 is interior tube body sectional view.
Description of reference numerals: 1-outer tube body, 2-interior tube body, 3-outer fluid cavity, 4-inner fluid cavity, 5-outer tube body tooth, 6-interior tube body thermal trough.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises outer tube body 1 and interior tube body 2, and interior tube body 2 is positioned at outer tube body 1.
The madial wall of outer tube body 1 is provided with multiple inwardly protruded outer tube body tooth 5, and multiple outer tube body tooth 5 is uniformly distributed along outer tube body 1 circumferencial direction.Multiple outer tube body tooth 5 front ends cooperating contact interior tube body 2, thus firm support interior tube body 2.
The madial wall of described outer tube body 1, between multiple outer tube body tooth 5 and interior tube body 2 outer side wall, form multiple separated outer fluid cavity 3, outer fluid cavity 3 uses as the passage of the external fluid of heat exchange, and multiple outer fluid cavity 3 is separated and can be improved heat exchange effect.
Be provided with inner fluid cavity 4 inside interior tube body 2, inner fluid cavity 4 uses as the passage of the internal flow of heat exchange.The madial wall of described interior tube body 2 is provided with multiple interior tube body thermal trough 6, and multiple interior tube body thermal trough 6 along the circumferential direction distributes twist.Due to the setting of thermal trough 6, the internal flow in inner fluid cavity 4 forms helical flow when flowing, and increases the contact heat-exchanging area of cavity fluid and interior pipe, improves heat exchange efficiency.The spiral chute quantity of interior tube body 2 inwall is more, and heat exchange area is larger, and heat exchange effect is better.
The utility model in use, inner fluid and outer fluid is passed into respectively in the inner chamber of interior tube body and outer tube body, inner fluid and outer fluid carry out heat exchange by interior tube body sidewall, at outer tube body madial wall, outer tube body tooth is set, outer fluid cavity uses as the passage of the external fluid of heat exchange, meanwhile, multiple outer fluid cavity is separated and can be improved heat exchange effect.Interior tube body madial wall arranges interior tube body thermal trough, and the internal flow in inner fluid cavity forms helical flow when flowing, and increases the contact heat-exchanging area of cavity fluid and interior pipe, improves heat exchange efficiency.The spiral chute quantity of interior tube body inwall is more, and heat exchange area is larger, and heat exchange effect is better.
