Abstract
The utility model relates to a D-type pipe concurrent flow condenser. Coolant of existing multielement concurrent flow condensers are not singly circulated in one loop but a plurality of loops, so that structure is complicated, heat exchange effect is poor, and resistance on coolant side and air side is high. The D-type pipe concurrent flow condenser comprises two parallel flow collecting pipes, and is characterized in that two pipe joint seats are mounted on the first flow collecting pipe, and the first flow collecting pipe and the second flow collecting pipe are connected through a plurality of flat pipes which are provided with a plurality of fins in an embedded manner. The D-type pipe concurrent flow condenser has the advantages of low pressure loss on the air side and the coolant side, high heat transfer coefficient, light weight, compact structure and low coolant filling quantity.
Description
Technical field
The utility model relates to the parts of the system of air conditioning for automobiles, especially a kind of D type pipe parallel flow condenser background technology
The refrigerant loop of existing polynary parallel flow condenser 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 utility model content
The utility model provides a kind of D type pipe parallel flow condenser at above-mentioned defective, and is simple and compact for structure, promotes the heat exchange effect, reduces the resistance of refrigerant side and air side.
For this reason, the utility model is taked following technical scheme, a kind of D type pipe parallel flow condenser, comprise two parallel headers, it is characterized in that installing on described first header two pipe joint seats, be connected by a plurality of flat tubes between first header and second header, be embedded with a plurality of fins on the described flat tube.Cold-producing medium enters first header of D type by pipe joint, and shunting enters oval flat tube then, and parallel second header that flows to the opposite is got back to the pipe joint seat by another flat tube at last.Be embedded with fin (fin) between the flat tube.Characteristics such as the pressure loss that this condenser has air side and refrigerant side is little, heat transfer coefficient is high, in light weight, compact conformation and filling quantity of refrigerant are few
The cross section of described header 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.
Described fin is ripple type, better heat-radiation effect.
The pressure loss that condenser of the present utility model has air side and refrigerant side is little, heat transfer coefficient is high, in light weight, compact conformation and the few advantage of filling quantity of refrigerant.
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.
D type pipe parallel flow condenser as shown in Figure 1 comprises two parallel headers, and the two ends that two pipe joint seat 1, the first headers 2 are installed on first header 2 connect second header 5 by flat tube 4 respectively, are embedded with a plurality of fins 3 between the flat tube 4.The cross section of header is the D type, the cross section ovalize of flat tube 4.Fin 3 is ripple type.The manufacturing process of condenser comprises welding (soldering) and product leak detection and the surface treatment etc. of the processing of processing, joint of assembling, the radiating fin of the processing of aluminum pipe and typing, pipeline or customization, finished product.
Cold-producing medium enters first header by pipe joint earlier, and shunting enters oval flat tube then, and parallel second header that flows to the opposite is got back to another pipe joint seat by another flat tube at last.Be embedded with fin (fin) between the flat tube.Characteristics such as the pressure loss that this condenser has 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.
Claims (3)
