Description

Technical Field

[0001] This utility model belongs to the field of PCT heating technology, and specifically relates to a heating core with a double S-channel. Background Technology

[0002] After the middle shell and water tank of the PTC heating core are assembled, the cavity formed is called the water chamber. The coolant flows in a direction in the water chamber, transferring the heat from the heating tank wall of the middle shell to the coolant, thus realizing the function of cooling and heating.

[0003] However, in existing PTC heating cores, the coolant flows through the water chamber in a relatively random direction, which can easily form eddies and generate eddy bubbles, leading to localized overheating and uneven heating. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a heating core with a double S-channel flow.

[0005] Therefore, this utility model provides a heating core with a double S-channel, including a middle shell and a water tank. The middle shell has multiple heating grooves arranged in parallel, which are concave and extend towards the bottom of the middle shell. The water tank has a water chamber, and the side wall of the water tank has an inlet pipe and an outlet pipe connected to the water chamber. A baffle is set in the middle of the water tank, and the baffle is located between the inlet pipe and the outlet pipe. One end of the baffle is closed and the other end is open, so that the coolant can only pass through the open end of the baffle. The inner side wall of the water tank also has a protruding edge, which is directly opposite to the heating groove of the heating groove and is closely attached to it. The protruding edge, the baffle and the heating groove together form a reciprocating flow channel in the water chamber.

[0006] Furthermore, the baffle is composed of two plates located on the same vertical plane. One plate is set on the water tank and fixedly connected to the inner wall of the water tank, while the other baffle is set on the middle shell and fixedly connected to the bottom surface of the middle shell.

[0007] Furthermore, a sealing ring is installed between the middle shell and the water tank.

[0008] Furthermore, a sealing groove is provided on the upper frame of the water tank, and a sealing ring is placed inside the sealing groove.

[0009] Furthermore, the frame of the middle shell is provided with multiple first positioning holes, and the frame of the water tank is provided with second positioning holes that correspond one-to-one with the positions of the first positioning holes.

[0010] Furthermore, the first positioning hole is a blind hole with the top closed, and the second positioning hole is a through hole. Both the first positioning hole and the second positioning hole are provided with internal threads.

[0011] This utility model provides a heating core with a double S-channel flow, which has the following beneficial effects:

[0012] By adding baffles, protruding edges, and heating grooves, some of the transverse flow paths in the water chamber are blocked, changing the flow direction of the coolant within the water chamber. This creates a double S-shaped reciprocating flow channel, reducing the generation of eddies and thus reducing the formation of air bubbles within the water chamber. This prevents localized overheating caused by eddies and air bubbles, resulting in more uniform heat exchange. At the same time, it reduces the movable volume of the coolant within the water chamber, increases the coolant flow rate, and improves heat exchange efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] like Figure 1 As shown, this utility model provides a heating core with a double S-channel, including a middle shell 1 and a water tank 3. The middle shell 1 has two symmetrically arranged sets of heating grooves 2, which are concave and extend towards the bottom of the middle shell 1. Each set of heating grooves 2 contains three parallel heating slots. The water tank 3 has an open water chamber without a top plate. The side wall of the water tank 3 has an inlet pipe 9 and an outlet pipe 10 connected to the water chamber. In one embodiment, the inlet pipe 9 and the outlet pipe 10 are located on two adjacent side walls of the water tank 3, distributed at 90 degrees; in another embodiment, the inlet pipe 9 and the outlet pipe 10 are located on two opposite side walls of the water tank 3, distributed at 180 degrees. Preferably, the inlet pipe 9 and the outlet pipe 10 are located on the same side wall of the water tank 3, at both ends of the side wall, increasing the movement path of the coolant within the water chamber and making the heat exchange more efficient.

[0019] like Figure 2As shown, the frame of the middle shell 1 is provided with multiple first positioning holes 7, and the frame of the water tank 3 is provided with second positioning holes 8 corresponding to the positions of the first positioning holes 7, and the bottom surface of the first positioning hole 7 and the top surface of the second positioning hole 8 coincide after installation. The first positioning hole 7 is a blind hole with a closed top, and the second positioning hole 8 is a through hole. Both the first positioning hole 7 and the second positioning hole 8 are provided with internal threads. In use, the heating element groove 2 of the middle shell 1 is inserted into the water chamber of the water tank 3, and a bolt is screwed from below the second positioning hole 8, passing through the second positioning hole 8 and into the interior of the first positioning hole 7 to fix it, thus completing the installation of the middle shell 1 and the water tank 3.

[0020] like Figure 2 As shown in Figure 3, a baffle 5 is provided in the middle of the water tank 3, and the baffle 5 is located between the inlet pipe 9 and the outlet pipe 10, dividing the water chamber into two symmetrical parts. One end of the baffle 5 is closed, and the other end is open, so that the coolant can only pass through the open end of the baffle 5. In one embodiment, the baffle 5 is provided on the water tank 3 and fixedly connected to the inner side wall of the water tank 3; in another embodiment, the baffle 5 is provided on the middle shell 1 and fixedly connected to the bottom surface of the middle shell 1; in another embodiment, the baffle 5 is composed of two plates located on the same vertical plane, wherein one plate is provided on the water tank 3 and fixedly connected to the inner side wall of the water tank 3, and the other plate baffle 5 is provided on the middle shell 1 and fixedly connected to the bottom surface of the middle shell 1. A protruding edge 11 is also provided on the inner side wall of the water tank 3, and the protruding edge 11 is directly opposite to and tightly attached to the middle heating groove of the heating chamber 2, so that the coolant cannot pass through here.

[0021] By adding baffle 5, protruding edge 11 and heating tank 2 in combination, part of the transverse flow path in the water chamber is blocked, changing the flow direction of the coolant in the water chamber and forming a double S-shaped reciprocating flow channel. This reduces the generation of eddies, thereby reducing the generation of bubbles in the water chamber and preventing local overheating caused by eddies and bubbles, making the heat exchange more uniform. At the same time, it also reduces the movable volume of the coolant in the water chamber, increases the flow rate of the coolant, and improves the heat exchange efficiency.

[0022] like Figure 2 As shown, a sealing ring 6 is also provided between the middle shell 1 and the water tank 3 to improve the sealing performance after the middle shell 1 and the water tank 3 are connected. A sealing groove 4 is provided on the upper frame of the water tank 3, and the sealing ring 6 is located inside the sealing groove 4.
