Automobile air conditioner parallel flow type warm air core

Abstract

The invention discloses an automobile air conditioner parallel flow type warm air core which comprises main boards, a water chamber wall face and multiple flat pipes. The multiple flat pipes are arranged at intervals. The two ends of each flat pipe are correspondingly welded to the main boards on the two sides. Cooling fins are arranged between the flat pipes. A cavity formed among the main boards and the water chamber wall face is divided into a water inflow chamber and a water outflow chamber through a separation board. A water inlet communicating with the water inflow chamber is formed in the water chamber wall face and connected with a heating and ventilation water inflow pipe. A water outlet communicating with the water outflow chamber is further formed in the water chamber wall face and connected with a heating and ventilation water outflow pipe. A baffle right opposite to the water inlet is arranged in the water inflow chamber, a baffle right opposite to the water outlet is arranged in the water outflow chamber, and multiple water flow holes are formed in each baffle. By the adoption of the automobile air conditioner parallel flow type warm air core, scouring by flowing water to the welding positions of the flat pipes and the main boards can be reduced, weld joints are protected against damage, and the service life is prolonged.

Description

technical field [0001] The invention belongs to an air conditioner warm air core body, in particular to a car air conditioner parallel flow type warm air core body. Background technique [0002] like figure 2 As shown, the existing automobile air conditioner parallel-flow heater core includes a main board 10, a water chamber wall surface 8 and a plurality of flat tubes 11, and the plurality of flat tubes 11 are arranged at intervals, and the two ends of each flat tube 11 are respectively connected to two The main board 10 on the side is correspondingly welded, and a heat dissipation fin 12 is provided between the flat tube 11 and the flat tube 11. The cavity formed between the main board 10 and the water chamber wall 8 is divided into a water inlet chamber 13 and a water outlet chamber through a partition 9 14. The water chamber wall 8 is provided with a water inlet 4 communicating with the water inlet chamber 13, the water inlet 4 is connected with the HVAC water inlet pip...

AI Technical Summary

Problems solved by technology

Similarly, there are multiple flat tubes 11 in the water outlet chamber 14 and the welding seams of the main board 10 are facing the water outlet 5. When the water flows out of the flat tubes 11, the water flows from all directions finally converge in one direction. The weld seam of the water outlet 5 will be washed by the water flow; when it is washed for a certain period of time, there will be gaps in the weld, which will cause leakage, which will cause the engine cooling system to fail and affect the safe use of the vehicle
