Abstract
The utility model relates to a plate fin type cold-stamped two-pedal buckled collector tube evaporator. A collector tube of an existing evaporator is of a traditional round tube structure, bad in radiation effect and not favorable of circulation of refrigerants. The plate fin type cold-stamped two-pedal buckled collector tube evaporator comprises a first collector tube arranged at the upper portion, a third collector tube arranged at the upper portion, a second collector tube arranged at the lower portion and a fourth collector tube arranged at the lower portion, wherein a plurality of flat tubes are parallelly arranged between the first collector tube and the second collector tube, a plurality of flat tubes are parallelly arranged between the third collector tube and the fourth collector tube, an inlet connector is arranged on the first collector tube, an outlet connector is positioned on the third collector tube, the collector tubes are all formed by two pedals which are buckled, and even partition grooves are all formed in the outer walls of the collector tubes. The plate fin type cold-stamped two-pedal buckled collector tube evaporator is of a novel collector tube structure, convenient to install and dismount, easy to maintain, capable of enabling work conditions to be easily checked, favorable of drainage of condensate water and capable of improving heat exchange effects.
Description
Technical field
The utility model relates to the parts of the system of air conditioning for automobiles, and especially a kind of plate-fin cold stamping bivalve is withheld the collector tube evaporimeter.
Background technology
The refrigerant loop of existing polynary parallel-flow evaporator is not a single circulation, but a plurality of circuit cycle of process, complex structure, the heat exchange effect is relatively poor, and the resistance of refrigerant side and air side is bigger.The traditional circular tube structure of collector tube employing of existing evaporimeter, radiating effect is poor, is unfavorable for the circulation of cold-producing medium, also is difficult for detecting or checking duty and the reparation that collector tube is interior.
The utility model content
The utility model provides a kind of plate-fin cold stamping bivalve to withhold the collector tube evaporimeter at above-mentioned defective, and is simple and compact for structure, promotes the heat exchange effect, is beneficial to the condensed water discharging, reduces the situation that evaporator surface freezes.
For this reason, the utility model is taked following technical scheme, a kind of plate-fin cold stamping bivalve is withheld the collector tube evaporimeter, it is characterized in that comprising first collector tube and the 3rd collector tube that are arranged on top, and second collector tube and the 4th collector tube that are arranged on the bottom, described first collector tube and the 3rd collector tube axially parallel arrange, and described second collector tube and the 4th collector tube axially parallel arrange; Walk abreast between described first collector tube and second collector tube a plurality of flat tubes are set, walk abreast between described the 3rd collector tube and the 4th collector tube a plurality of flat tubes are set, on described first collector tube import connector is set, on described the 3rd collector tube outlet connector is set, described collector tube is withheld by two lobes and is made, and forms uniform interval trough on the outer wall of described collector tube.The structure of collector tube makes easy installation and removal, for ease of maintenaince checks operating mode, is beneficial to the discharging of condensed water, promotes the heat exchange effect.
The dual-side of evaporimeter strikes out bending edge by the aluminium skin, is beneficial to the condensed water discharging, reduces the situation that evaporator surface freezes.
The cross section of described first collector tube, second collector tube, the 3rd collector tube, the 4th collector tube is the D type, the cross section ovalize of described flat tube.D type pipe contrast pipe is when identical sectional area, and D type inside pipe wall girth is greater than pipe, make cold-producing medium and air to contact circumference bigger, being easy to dispel the heat reduces the circulating resistance of quality cold-producing medium, it is faster and better to dispel the heat under the equal conditions.
Connect fin on the described flat tube outer wall, described fin is ripple type.
The polylith dividing plate is set in the described collector tube.
Evaporation structure of the present utility model is simply compact, is beneficial to the condensed water discharging, and good effect of heat exchange reduces the situation that evaporator surface freezes.Operating mode is for ease of maintenaince checked in mechanism's easy installation and removal of collector tube, is beneficial to the discharging of condensed water, promotes the heat exchange effect.
Description of drawings
Fig. 1 is the structural representation of utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of plate-fin cold stamping bivalve is withheld the collector tube evaporimeter as shown in Figure 1, comprises first collector tube 1 and the 3rd collector tube that are arranged on top, and second collector tube 5 and the 4th collector tube 7 that are arranged on the bottom.First collector tube 1 and the 3rd collector tube axially parallel arrange, second collector tube 5 and the 7 axially parallel settings of the 4th collector tube.Walking abreast between first collector tube 1 and second collector tube 5, arranging walks abreast to arrange to arrange on import connector 2, the three collector tubes on a plurality of flat tube 8, the first collector tubes 1 between a plurality of flat tube 8, the three collector tubes and the 4th collector tube 7 arranges the outlet connector.First, second, third, fourth collector tube is withheld by two lobes and is made, and forms uniform interval trough (not shown) on its outer wall, and the dual-side of evaporimeter strikes out bending edge 9 by the aluminium skin.
The cross section of first collector tube 1, second collector tube 5, the 3rd collector tube, the 4th collector tube 7 is the D type, the cross section ovalize of flat tube 8.D type pipe contrast pipe is when identical sectional area, and D type inside pipe wall girth is greater than pipe, make cold-producing medium and air to contact circumference bigger, being easy to dispel the heat reduces the circulating resistance of quality cold-producing medium, it is faster and better to dispel the heat under the equal conditions.Connect fin 4 on flat tube 8 outer walls, fin 4 is ripple type, and polylith dividing plate 6 is set in the collector tube.
Cold-producing medium enters first collector tube by the import connector earlier, shunting enters oval flat tube then, parallel second collector tube that flows to the opposite and the 4th collector tube, the refrigerant volume expansion, flash to gaseous state, absorb heat, gaseous coolant has flat tube to get back to the 3rd collector tube again, is got back in the automobile pipeline by the outlet connector.Be embedded with fin (fin) between the flat tube.Characteristics such as this evaporation apparatus has that the pressure loss of air side and refrigerant side is little, heat transfer coefficient is high, in light weight, compact conformation and filling quantity of refrigerant are few.
Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
