Description

Technical Field

[0001] The utility model belongs to the technical field of thick film heating, and particularly relates to a thick film heating core with good heat exchange effect. Background Art

[0002] In most existing thick film heating cores, coolant flows through a water chamber formed by an intermediate shell and a thick film heating plate to take away the heat of the thick film heating plate. However, relying solely on the coolant to take away the heat of the thick film heating plate makes it difficult to ensure the uniformity of the surface temperature of the thick film heating plate and difficult to ensure the use safety. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the above technical deficiencies and provide a thick film heating core with good heat exchange effect.

[0004] To this end, the utility model provides a thick film heating core with good heat exchange effect, which includes an intermediate shell. A cavity is formed inside the intermediate shell to form a water chamber. An inlet and an outlet are formed on the side surface of the intermediate shell, and both are communicated with the water chamber. Fins are arranged in the water chamber. The fins are fixedly connected to the intermediate shell and are arranged between the inlet and the outlet. A thick film heating plate is installed on the intermediate shell through a plurality of assembly holes. The fins are in contact with but not connected to the thick film heating plate.

[0005] Further, the fins are formed by staggered arrangement of continuous undulating fin units, and can form a plurality of water flow channels in the horizontal direction and cavities in the vertical direction.

[0006] Further, two groups of positioning baffles are fixedly connected to the intermediate shell for determining the installation position of the fins.

[0007] Further, sealing grooves are formed at positions around the water chamber on the intermediate shell.

[0008] Further, limiting convex edges are arranged around the intermediate shell and are matched with the thick film heating plate.

[0009] Further, an installation hole is formed on one side of the intermediate shell for subsequent installation of a busbar.

[0010] The thick film heating core with good heat exchange effect provided by the utility model has the following beneficial effects:

[0011] 1. High degree of integration. The fins of the intermediate shell can be directly fixed at the supplier, realizing the integration of the intermediate shell and the fins, without subsequent processes, with low installation cost, convenient incoming material inspection and easy control.

[0012] 2. Easy to install, simple process, can ensure the consistency of products during the production process, and is easy to control.

[0013] 3. High safety factor. As the working time of the thick film heating core increases, even if the thick film heating plate is deformed, it will not cause deformation and displacement of the fins, will not cause turbulence, and can ensure the uniformity of the surface temperature of the thick film heating plate.

[0014] 4. As the coolant flow rate increases, it will not cause displacement of the fins, better increase heat dissipation, and reduce local overheating of the thick film heating plate. Description of the Drawings

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0021] As Figures 1-3 shown, the present invention provides a thick film heating core with good heat exchange effect, including a middle shell 1. A cavity is formed inside the middle shell 1 to form a water chamber. A water inlet 3 and a water outlet 4 are provided on the side of the middle shell 1, both of which are connected to the water chamber. Fins 2 are arranged in the water chamber. The fins 2 are fixedly connected to the middle shell 1 and are arranged between the water inlet 3 and the water outlet 4. A thick film heating plate 5 is installed on the middle shell 1 through a plurality of assembly holes 8. The fins 2 are in contact with but not connected to the thick film heating plate 5. By arranging the fins 2, the heat exchange area can be increased when the coolant flows through the thick film heating plate 5, which can not only improve the heat exchange efficiency but also ensure the uniformity of the surface temperature of the thick film heating plate 5.

[0022] As Figure 4As shown, the fin 2 is formed by the staggered arrangement of continuous undulating fin units, which can form a plurality of water flow channels 11 in the horizontal direction and a plurality of cavities 12 in the vertical direction. Since the fin 2 is in direct contact with the thick film heating plate 5, the heat of the thick film heating plate 5 can be directly transferred to the fin 2. When the coolant passes through the water flow channels 11 and through the fin 2, heat transfer occurs with the fin 2, and the coolant exchanges heat indirectly with the thick film heating plate 5; and when the coolant flows through the position of the cavity 12, an overflow can occur, and the coolant will be in direct contact with the thick film heating plate 5 for direct heat exchange; the heat exchange efficiency is further improved through these two heat exchange forms.

[0023] When the coolant is passed: the thick film heating plate 5 starts to work and generate heat; the coolant flows through the water chamber formed by the middle shell 1 and the thick film heating plate 5, taking away the heat of the thick film heating plate 5. However, relying solely on the coolant to take away the heat of the thick film heating plate 5, it is difficult to ensure the uniformity of the surface temperature of the thick film heating plate 5 and difficult to ensure the use safety. Therefore, it is necessary to add the fin 2 between the thick film heating plate 5 and the middle shell 1 (that is, inside the water chamber). Fixing the fin 2 inside the middle shell 1 to complete the integration of the middle shell 1 and the fin 2 can solve the problem of local overheating on the surface of the thick film heating plate 5. At the same time, the integration of the middle shell 1 and the fin 2 can avoid problems such as the displacement and deformation of the fin 2 during the operation of the thick film heating core, ensuring the heat exchange efficiency of the thick film heating core while ensuring the use safety of the thick film heating core.

[0024] As Figure 3 shown, two groups of positioning baffles 9 are also fixedly connected to the middle shell 1 to determine the installation position of the fin 2. The direction of the positioning baffle 9 extends from the water inlet 3 to one side of the fin 2 and can also play a role in guiding the flow. Sealing grooves 6 are opened at the positions around the water chamber on the middle shell 1, and the sealing between the middle shell 1 and the thick film heating plate 5 is ensured by filling sealing materials in the sealing grooves 6.

[0025] Limit convex edges 10 that cooperate with the thick film heating plate 5 are also provided around the middle shell 1 to prevent the thick film heating plate 5 from being misaligned in the middle shell 1. An installation hole 7 is also opened on one side of the middle shell 1 for subsequent installation of the bus bar plate.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] However, the above are only specific embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of patent protection of the present utility model, should still fall within the scope covered by the claims of the present utility model.
