Description

Technical Field

[0001] The utility model relates to the field of flow channel structures. More specifically, the utility model relates to a flow channel structure for thick film heating. Background Art

[0002] The flow channel structure is used to define the flow path and mode of fluid in a hydraulic system or an injection mold, and its design is crucial for the performance and efficiency of the system. However, the existing flow channel structure does not have the function of uniformly heating the liquid during use, resulting in a narrow range of applications. In addition, it is not convenient to filter the liquid entering the flow channel structure, which causes impurities in the coolant to enter the inside of the flow channel structure, resulting in flow channel blockage, thereby affecting the heating effect of the coolant. Summary of the Invention

[0003] The purpose of the utility model is to provide a flow channel structure for thick film heating, which can quickly and uniformly heat the coolant flowing through the flow channel structure, and at the same time can filter the coolant entering the flow channel structure to prevent impurities in the coolant from entering the flow channel and causing flow channel blockage.

[0004] To achieve these and other advantages in accordance with the present utility model, there is provided a flow channel structure for thick film heating, comprising:

[0005] A housing having a sealed cavity; [[ID=[]]

[0006] A flow guiding groove body disposed in the sealed cavity. An inlet pipe and an outlet pipe are provided on the housing and are respectively communicated with the inlet and outlet of the flow guiding groove body. A filtering assembly is provided in the inlet pipe;

[0007] A heating thick film disposed in the sealed cavity and attached to the flow guiding groove body. The heating thick film seals the opening of the flow guiding groove on the flow guiding groove body to form a flow channel. The beneficial effects of the present utility model are:

[0008] 1. In the flow channel structure of the present utility model, a single-layer flow channel structure is provided to guide the coolant, and the heating thick film is energized to release heat, which can quickly and uniformly heat the coolant. The inlet pipe and the outlet pipe of the flow channel are arranged on the same side, reducing the length of the flow channel structure, so that the flow channel structure can be applied to the use environment with limited space in the height direction.

[0009] 2. In the flow channel structure of the present utility model, a filtering assembly is provided in the inlet pipe, which can filter the coolant entering the flow channel structure to prevent impurities in the coolant from entering the flow channel and causing flow channel blockage.

[0010] Based on the above technical solutions, the present utility model can be further improved as follows:

[0011] Further, in the described thick-film heating flow channel structure, an installation groove for placing the diversion groove body is provided on one inner wall of the sealing cavity. A positioning groove corresponding to the heating thick film is provided at the edge of the installation groove.

Then, the heating thick film 7 is placed in the positioning groove 23, and the outer edge of the heating thick film 7 is attached to the side wall of the positioning groove 23. After the heating thick film 7 is fixed by the connecting member 9, a force is applied to the heating thick film 7 towards the diversion groove body 8, so that the heating thick film 7 is closely attached to the diversion groove body 8, and the diversion groove body 8 also abuts against the bottom of the installation groove 11, thereby forming a sealed flow channel between the heating thick film 7 and the diversion groove body 8.
