Description

Technical Field

[0001] This utility model belongs to the field of fuel cells, and specifically relates to a top-mounted heat dissipation module for fuel cells. Background Technology

[0002] The core principle of a hydrogen fuel cell is an electrochemical reaction. At the anode, hydrogen is decomposed into protons and electrons by a catalyst. The protons pass through the electrolyte membrane to the cathode, while the electrons flow through an external circuit, forming an electric current. Subsequently, the protons combine with oxygen at the cathode to produce water. The entire process is pollution-free, emitting only water, making hydrogen fuel cell vehicles very environmentally friendly.

[0003] Hydrogen fuel cell vehicles require radiators for cooling during operation. Current fuel cell radiators have the following drawbacks: the mounting brackets are not secure enough during welding and have low strength; and the mounting brackets are made of heavy materials, which do not meet the lightweight requirements for vehicle operation. Utility Model Content

[0004] The purpose of this invention is to provide a top-mounted heat dissipation module for fuel cells, which can improve the strength of the heat dissipation mounting bracket, making the heat dissipation installation more secure, and reducing the material thickness to meet the requirements of lightweighting.

[0005] The purpose of this utility model is achieved as follows: A top-mounted heat dissipation module for fuel cells includes a heat sink body, which is horizontally arranged. Two spaced mounting brackets are arranged on both the left and right sides of the heat sink body. Each mounting bracket includes a rectangular main board that fits against the outer periphery of the heat sink body. The main board is vertically arranged and welded to the heat sink body on all four sides. The main board has plug welding holes. A rectangular base plate located below the main board is welded to the heat sink body. The base plate is horizontally arranged and welded to the main board. Two symmetrical reinforcing ribs are arranged between the base plate and the main board. The reinforcing ribs are right-angled triangles, and the two right-angled sides of the reinforcing ribs are welded to the main board and the base plate, respectively.

[0006] The radiator body of this invention is mounted on top of a hydrogen frame via a mounting bracket. The mounting bracket consists of a base plate, a main plate, and two reinforcing ribs, forming a triangular bracket with a hollow interior. The reinforcing ribs ensure the bracket's strength. During radiator installation, the base plate of the mounting bracket is fixed to the hydrogen frame using fasteners passing through mounting holes. When welding the main plate to the radiator body, solder extends into the plug weld holes to increase strength. Compared to existing technologies, the advantages of this invention are: improved strength of the radiator mounting bracket, resulting in a more secure radiator installation; and reduced material thickness, meeting lightweight requirements.

[0007] As a further improvement of this utility model, the heat sink body is rectangular.

The inlet pipe and the outlet pipe are respectively connected to the first water chamber and the second water chamber. A heat dissipation core is provided between the first water chamber and the second water chamber. The heat dissipation core is a tube-strip core or a plate-fin core. The heat dissipation core is provided with a channel connecting the first water chamber and the second water chamber, and the liquid circulates between the two water chambers. A fan blows downwards towards the heat dissipation core to dissipate heat.

[0009] As a further improvement of this utility model, an air guide shroud is provided on the upper side of the radiator body. The air guide shroud includes a horizontal top plate, which is rectangular in shape. Four side plates forming a rectangle are provided on the lower side of the top plate. The side plates are vertically arranged, and their lower edges are fixed to the radiator body.

The main plate 3 is vertically positioned, and its four sides are welded and fixed to the heat sink body 1. The main plate 3 has plug welding holes 4. A rectangular base plate 5 located below the main plate 3 is welded and fixed to the heat sink body 1. The base plate 5 is horizontally positioned and is also welded and fixed to the main plate 3. Two symmetrical reinforcing ribs 7 are provided between the base plate 5 and the main plate 3. The reinforcing ribs 7 are right-angled triangles, and their two right-angled sides are welded and fixed to the main plate 3 and the base plate 5, respectively.

[0018] The radiator body 1 has an inlet pipe 8 and an outlet pipe 9 on its lower side, with their axes vertically aligned. The radiator body 1 includes a first water chamber 10 and a second water chamber 11 spaced apart. The inlet pipe 8 and outlet pipe 9 are connected to the first water chamber 10 and the second water chamber 11, respectively. A heat dissipation core 12 is disposed between the first water chamber 10 and the second water chamber 11. The heat dissipation core 12 can be a tube-strip type or a plate-fin type. The heat dissipation core 12 has channels connecting the first water chamber 10 and the second water chamber 11, allowing liquid to circulate between the two chambers. A fan blows downwards onto the heat dissipation core 12 for heat dissipation.

[0019] A guide shroud 13 is provided on the upper side of the radiator body 1. The guide shroud 13 includes a horizontal top plate 13a, which is rectangular. Four rectangular side plates 13b are provided on the lower side of the top plate 13a. The side plates 13b are vertically arranged, and their lower edges are fixed to the radiator body 1.
