Description

Technical Field

[0001] This belongs to the category of parallel flow heat exchangers for automotive air conditioning, and specifically involves the side panels. Background Technology

[0002] Parallel flow heat exchangers (mainly including condensers, evaporators, warm air tanks, and oil coolers) are widely used in existing thermal management systems. The side plate, as one of the four main components of the heat exchanger core, plays a crucial role in support, protection, and sealing, and is inseparable from the fins and manifolds. Existing conventional structures are straight-line and U-shaped. In actual design, when the fluid inlet and outlet cannot be directly welded to the manifold, an additional conduit needs to be led to the designated location and fixed to the side plate. This results in a limited conduit lead-out direction, complex manufacturing process, high production costs, large space occupation, poor welded seals at the conduit lead-out, and a risk of media leakage. Summary of the Invention

[0003] The purpose of this utility model is to provide a side plate for a parallel flow evaporator, which has a channel and is compact in structure, simple in process, reliable in sealing and high in strength.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A side plate for a parallel flow heat exchanger is characterized in that: the side plate has an overall I-shaped cross-section, with grooved channels on both sides, and a hollow structure in the middle of the side plate to form a hollow flow channel.

[0006] The side plate is welded vertically to the manifold, the hollow flow channel in the side plate is connected to the manifold, the flat tube is welded to the manifold and is connected to it, the fins are welded between the two flat tubes, and the inlet and outlet pipe joints are welded at any position on the side plate and are connected to it.

[0007] The advantages of this utility model are:

[0008] 1. High versatility: The side plates are universal for parallel flow heat exchangers (condensers, evaporators, water tanks, oil coolers, etc.), and the production process molds are also universal;

[0009] 2. High reliability: The side plate adopts an I-shaped stable structure, which enhances strength; the channel adopts a circular structure, which is resistant to high pressure; the welding surface with the manifold adopts an arc surface, which has a large contact surface and a large welding surface, resulting in an extremely low leakage rate.

[0010] 3. High functionality: The side panel with access can be connected to inlet and outlet connectors in multiple dimensions, making it flexible and versatile to meet various external connection needs;

[0011] 4. Low cost: The side plate is formed by drawing an integral profile, which integrates the side plate channel into one. The heat exchanger production process is simple. Compared with the external duct type structure, the fixing process before furnace welding is eliminated; the flame welding fixing tooling is reduced. Attached Figure Description

[0012] Figure 1 This is the front view of the present utility model;

[0013] Figure 2 This is a side view of the present invention;

[0014] Figure 3 This is a schematic diagram of the structure used in this application. Detailed Implementation

[0015] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0016] See Figure 1-2 The side plate 3 has an overall I-shaped cross section with grooved channels on both sides and a hollow structure in the middle, forming a hollow flow channel 6.

[0017] See Figure 3 The side plate 3 is welded vertically to the manifold 1. The hollow flow channel 6 in the side plate 3 is connected to the manifold 1. The flat tube 2 is welded to the manifold 1 and connected to it. The fin 4 is welded between the two flat tubes. The inlet and outlet pipe joints 5 are welded at any position on the side plate 2 and connected to it.

[0018] The main structure of side plate 3 adopts an I-shaped, hollow structure in the middle. The I-shaped structure can strengthen the side plate and better protect the entire core. The fluid flowing through the heat exchange flows from the flat tube 2 to the manifold 1, and then from the manifold 1 through the flat tube channel. The inlet and outlet joints 5 are connected to the corresponding pipelines. The hollow flow channel 6 on the side plate runs through the entire side plate. The inlet and outlet joints can be drilled and welded at any position on the side plate to connect with the side plate. The joints can rotate 360° spherically and can be connected to the external joints in multiple dimensions to achieve the best connection position with the pipeline.
