Description
Technical Field
[0001] This utility model relates to the field of pump frequency converter technology, and in particular to a heat dissipation structure for pump frequency converters. Background Technology
[0002] The heat dissipation structure of a pump inverter is a temperature management system specifically designed for power control equipment that regulates pump speed. It integrates both active and passive cooling methods to rapidly dissipate heat generated by the inverter's internal electronic components. A typical structure includes a heat-conducting substrate, heat sink fins, and ventilation ducts. Some advanced designs also incorporate intelligent temperature control systems that automatically increase cooling power or activate backup cooling modules when high temperatures are detected, ensuring the inverter maintains a stable operating temperature under various conditions, thereby extending equipment lifespan and maintaining energy efficiency. However, existing pump inverter heat dissipation structures still suffer from the inability to create specific cooling ducts, quickly dissipate heat from the inverter's interior, and effectively remove heat from the inverter's surface.
[0003] Therefore, it is essential to invent a heat dissipation structure for pump frequency converters. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a heat dissipation structure for a pump inverter, solving the issues that existing pump inverter heat dissipation structures still cannot form a specific heat dissipation airflow, quickly dissipate heat from inside the inverter, or quickly remove heat from the inverter surface. A pump inverter heat dissipation structure includes an inverter, an internal heat dissipation structure, a supporting shell, a heat dissipation shell, a sealing shell, and an adsorption seal. The supporting shell is fixedly installed on the inner wall of an electrical cabinet, and the inverter is fixedly installed inside two sets of supporting shells. The internal heat dissipation structure is fixedly installed at the upper and lower ends of the inverter. The heat dissipation shell is rotatably installed on the outside of the supporting shell, and the sealing shell is rotatably installed on the outside of another set of supporting shells. The adsorption seal is fixedly installed at one end of the sealing shell and adsorbs onto the heat dissipation shell.
[0005] The supporting shell includes a heat-conducting plate, a connecting plate, a connecting base, and a supporting hinge. The heat-conducting plate is fixedly installed on the outer walls of both sides of the inverter. The connecting plate is fixedly installed on the rear end of the two sets of heat-conducting plates and on the inner wall of the electrical cabinet. The connecting base is fixedly installed on the surface of the connecting plate, and the supporting hinge is rotatably installed on the connecting base and connected to the heat dissipation shell and the enclosed shell respectively.
[0006] The heat dissipation housing includes a folding housing, a connecting frame, an external heat dissipation structure, and a connecting seal. The folding housing is installed on the outside of the supporting housing, and the connecting frame is fixedly installed on the upper and lower ends of the inside of the folding housing. The external heat dissipation structure is fixedly installed on two sets of connecting frames, and the connecting seal is fixedly installed on the folding housing.
[0007] The supporting shell consists of two sets, mirrored on both sides of the inverter with the centerline as the axis; the heat-conducting plate is a copper metal plate with heat-absorbing fins on its surface, extending through the inverter's shell into its interior; the connecting plate has mounting holes inside, allowing it to be bolted to the inner wall of the electrical cabinet; the connecting base and supporting hinge can rotate to open and close the heat dissipation shell and the closed shell.
[0008] The folding shell and connecting frame inside the heat dissipation shell can cooperate with the closed shell to form a set of vertically continuous rectangular cylindrical structures; the external heat dissipation structure adopts two sets, and the external heat dissipation structure can close both ends of the rectangular tube formed by the folding shell, connecting frame and closed shell. The external heat dissipation structure only moves with the opening and closing of the folding shell; the external heat dissipation structure is located directly above and directly below the frequency converter.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The supporting shell of this utility model can be set up so that the heat-conducting plate can be close to the heat-generating element inside the frequency converter and the heat can be quickly dissipated by the high thermal conductivity of copper. At the same time, the connecting plate is fixed to the inner wall of the electrical cabinet to provide shock-resistant support. The connecting base and the supporting hinge form a rotating mechanism to realize the opening and closing control of the heat dissipation shell and the closed shell, and finally form a fixed and efficient heat conduction function, thereby improving the heat dissipation efficiency.
[0011] The heat dissipation shell of this invention is designed with a combination of external heat dissipation structure and heat dissipation fins, positioned directly above and below the frequency converter. This structure is directly connected to the internal heat source of the frequency converter via a heat-conducting plate, and together with the folding shell and connecting frame, forms a closed heat dissipation airflow channel. The entire structure moves synchronously with the opening and closing of the heat dissipation shell, forming a passive and efficient heat dissipation path to expel heat from the surface of the frequency converter, effectively improving overall heat dissipation efficiency.
