Problems solved by technology

In the parallel flow core platform in the existing industry, it is necessary to reduce the thickness of the core to reduce the weight. By directly reducing the width of the flat tube, the area of ​​the refrigerant flow channel will be reduced, and the refrigerant flow on the refrigerant side will be reduced; The exchange area is reduced due to the shortening of the fins, and the heat exchange capacity of the wind side is insufficient, resulting in insufficient cooling capacity per unit area of ​​the core of the entire parallel flow evaporator
On the other hand, if the weight reduction depends solely on thinning the wall thickness of the flat tube, the pressure of the flat tube will not meet the requirements, and the corrosion resistance of the thin wall will decrease

Embodiment Construction

[0025] see Figure 1 to Figure 6 , in a preferred embodiment, the lightweight high-performance parallel-flow evaporator core includes flat tubes and fins arranged on the flat tubes, the thickness of the core is X, 28mm≤X<34mm; the flat tubes The thickness is 2.3-2.4mm, the wall thickness (side wall thickness) of the flat tube is 0.18-0.25mm, the width of the flat tube is 14-16mm, the opening angle of the fin is 32°-38°, and the wave height (height) is 4.5-5.5mm . In a preferred embodiment, the thickness of the flat tube is 2.35 mm, the thickness of the flat tube is 0.18 mm, and the wave height of the fin is 5 mm. Increase the thickness of the flat tube to 2.35mm, reduce the wall thickness of the flat tube to 0.18mm to increase the inner hole area of ​​the flat tube, ensure the area of ​​a single flat tube refrigerant channel, and reduce the fin wave height to 5mm to increase the flat tube on the windward surface Quantity to ensure the entire core flow to the area.

Abstract

The invention discloses a lightweight high-performance parallel flow type evaporator core. The lightweight high-performance parallel flow type evaporator core comprises flat tubes and fins arranged atthe flat tubes, the thickness of the core is X, and X is equal to or greater than 28mm and is less than 34mm. The lightweight high-performance parallel flow type evaporator core is light and good inheat exchange efficiency.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a lightweight high-performance parallel-flow evaporator core. Background technique [0002] A heat exchanger is a device that transfers heat between different media, and is widely used in automotive air-conditioning condensers and evaporators. The core of the heat exchanger is energy saving. The core body of the evaporator has been developed from the tube-sheet type, the tube-belt type, and the stacked type to the current parallel flow, and the performance has been greatly improved, and the cost of raw materials has also been reduced. [0003] At the same time, in response to the national call for "energy saving and emission reduction", new energy vehicles are developing rapidly. In order to increase the mileage of new energy vehicles, it is particularly important to reduce the weight of the vehicle and improve the heat exchange efficiency. The parallel flow evaporator also reduces...
