Embodiment 1

[0027] The present invention relates to a supercooled extension condenser for a vehicle, comprising a condenser body 1, a supercooled extension process 2 is connected to the outlet end of the condenser body 1, and the supercooled extension process 2 is arranged on the windward surface of the condenser body 1.

[0028] see figure 1 , The condenser body 1 includes two headers 11 arranged in parallel, a plurality of parallel heat dissipation flat tubes 12 , a plurality of partitions 13 and a liquid storage drying tank 14 . Both ends of the radiating flat tube 12 communicate with two collecting tubes 11 respectively, and a plurality of radiating flat tubes 12 and the collecting tubes 11 form a cavity in which the refrigerant flows and dissipates heat. The partition plate 13 in the header 11 separates the cavity to form a flow channel, and the refrigerant in the flow channel flows in a serpentine path. The liquid storage and drying tank 14 is arranged on the collector pipe 11 of t...

Embodiment 2

[0038] see Figure 4 The difference between this embodiment and the first embodiment is that the position of the subcooling extension process 2 on the condenser body 1 is different. In this embodiment, the subcooling extension process 2 is relatively overlapped and arranged on the windward side of the condenser body 1 . The left liquid collector 22 and the right liquid collector 23 in the subcooling extension process 2 are fixedly arranged on the outside of the collector 11 in parallel, wherein the right liquid collector 23 extends vertically downward to form a delivery pipe section 231, and the delivery pipe section 231 communicates with the outlet of the subcooling section. In this embodiment, the subcooling extension process 2 can be arranged at the position above the condensation section 15 or the subcooling section 16 of the condenser body 1, and of course it can also be arranged at a position between the condensation section 15 and the supercooling section 16. Location...

Abstract

The invention relates to a vehicle supercooling extension condenser. The vehicle supercooling extension condenser comprises a condenser body; and the condenser body comprises a condensation section, astored liquid drying tank and a supercooling section serially connected in sequence. The vehicle supercooling extension condenser further comprises a supercooling extension flow communicating with anoutlet of the supercooling section; and the supercooling extension flow is arranged on a windward surface of the condenser body. The vehicle supercooling extension condenser guarantees the heat exchange efficiency of the condenser under the condition of reducing the windward area of the supercooling section.

Description

technical field [0001] The invention relates to a condenser; in particular, to a supercooled extended condenser for vehicles. Background technique [0002] The existing condenser adopts a unilateral flow collecting structure to flow and dissipate the refrigerant. The condenser adopts a collector structure, and the refrigerant inside it flows in one direction in the condenser in a serpentine flow to dissipate heat. The collecting structure mainly includes a plurality of mutually independent collecting pipe sections, radiating flat tubes 12 and liquid storage drying tank 14 , and the collecting pipe section is a transfer station for the refrigerant flow in the radiating flat pipes 12 to change directions. Under the combination of multiple header sections and the heat dissipation flat tubes 12, the path for the refrigerant to flow and dissipate heat is increased. In actual production, in order to improve the connection stability between the heat-dissipating flat tube 12 and t...
