A high-strength, corrosion-resistant aluminum radiator

Abstract

The utility model belongs to the technical field of radiators, and specifically discloses a high-strength, corrosion-resistant aluminum radiator, including a heat sink and a plurality of heat sink fins, wherein the heat sink fins are a semicircular structure with continuous concave-convex folding, and the heat sink fins are arranged parallel and equidistantly along the length direction of the heat sink. The surfaces of the heat sink and the heat sink fins are sequentially provided with a reinforcing layer and a corrosion-resistant layer from the inside to the outside.

Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a high-strength and corrosion-resistant aluminum radiator. Background Art

[0002] Aluminum radiator is a device made of aluminum material for heat dissipation. Radiators are usually used to absorb the heat generated by equipment or systems and effectively dissipate it to the surrounding environment to ensure that the equipment operates within the normal operating temperature range.

[0003] Aluminum radiators usually have high structural strength, mainly because aluminum alloy has excellent strength and lightweight characteristics. Aluminum alloy has low density but high strength, and has excellent tensile, compressive and bending resistance, so it is widely used in the field of radiator manufacturing.

[0004] However, the cooling fins of the current aluminum radiators are mostly flat-plate type, with a small contact area with the air, and the heat dissipation effect needs to be improved. In addition, the radiator is prone to corrosion and damage after long-term use. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a high-strength, corrosion-resistant aluminum radiator.

[0006] In order to solve the background technical problems, the utility model adopts the following technical solutions.

[0007] A high-strength, corrosion-resistant aluminum radiator comprises a heat dissipation base and a plurality of heat dissipation fins. The heat dissipation fins are semicircular structures with continuous concave-convex folds. The heat dissipation fins are arranged in parallel and equidistantly along the length direction of the heat dissipation base. The surfaces of the heat dissipation base and the heat dissipation fins are provided with a reinforcement layer and a corrosion-resistant layer in sequence from the inside to the outside.

[0008] As a further description of the above technical solution: the reinforcement layer is an anti-corrosion nickel-chromium plating layer.

[0009] As a further description of the above technical solution: the corrosion-resistant layer includes an inner corrosion-resistant film and an outer corrosion-resistant layer, the inner corrosion-resistant film is coated on the surface of the reinforcement layer, and the outer corrosion-resistant layer is coated on the surface of the inner corrosion-resistant film.

[0010] As a further description of the above technical solution: the inner corrosion-resistant film is a high-temperature oxidation film corrosion-resistant layer, and the outer corrosion-resistant layer is an epoxy resin anti-corrosion coating.

[0011] As a further description of the above technical solution: the heat dissipation fins and the heat dissipation base are integrally formed.

[0012] As a further description of the above technical solution: a plurality of heat-conducting grooves are equidistantly arranged on the back of the heat dissipation base, and the cross-section of the heat-conducting grooves is a trapezoidal structure.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. This solution improves the shape of the heat sink fins while maintaining a tight arrangement of the radiator. By designing the heat sink fins as a semicircular structure with continuous concave and convex folds, the surface area of ​​the heat sink fins in contact with the air is increased, and the local channel width between two adjacent heat sink fins is increased, so that the air flow through the local gap is larger, thereby improving the heat dissipation effect.

[0015] 2. This solution further improves the corrosion resistance of the radiator by adding a reinforcement layer and corrosion resistance to the outer surface of the aluminum radiator, avoiding corrosion damage after long-term use, ensuring the normal operation of the radiator and easy use.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1A high-strength, corrosion-resistant aluminum heat sink includes a heat sink base 1 and a plurality of heat sink fins 2. The heat sink fins 2 are semicircular structures with continuous concave-convex foldings. The heat sink fins 2 are arranged parallel and equidistantly along the length direction of the heat sink base 1. The heat sink fins 2 are integrally formed with the heat sink base 1. This embodiment improves the shape of the heat sink fins 2 on the basis of keeping the heat sink tightly arranged. By designing the heat sink fins 2 as semicircular structures with continuous concave-convex foldings, the surface area of ​​the heat sink fins in contact with the air is increased, and the width of the local channel gap between two adjacent heat sink fins 2 is increased (for example, the spacing between two adjacent heat sink fins 2 at the concave-convex connection is smaller than the width at the corresponding part of the convex part or the corresponding part of the concave part), so that the air flow through the local gap is larger and the heat dissipation effect is better.

[0023] In addition, a plurality of heat-conducting grooves 5 are evenly spaced on the back of the heat-dissipating base 1 . The cross-section of the heat-conducting grooves 5 is a trapezoidal structure, which increases the heat-dissipating area of ​​the heat-dissipating base 1 and further improves the heat-dissipating effect.

[0024] Example 2

[0025] See also Figure 2 Based on the above embodiment, the surfaces of the heat dissipation base 1 and the heat dissipation fins 2 are provided with a reinforcement layer 3 and a corrosion-resistant layer 4 from the inside to the outside. The reinforcement layer 3 is an anti-corrosion nickel-chromium plating layer. The corrosion-resistant layer 4 includes an inner corrosion-resistant film 41 and an outer corrosion-resistant layer 42. The inner corrosion-resistant film 41 is coated on the surface of the reinforcement layer 3, and the outer corrosion-resistant layer 42 is coated on the surface of the inner corrosion-resistant film 41. The inner corrosion-resistant film 41 is a high-temperature oxidation film corrosion-resistant layer. The high-temperature oxidation film is a surface oxidation film formed by a metal material or a coating in an oxygen-containing medium at a high temperature. The outer corrosion-resistant layer 42 is an epoxy resin anti-corrosion coating, and the thickness of the epoxy resin anti-corrosion coating is 20-30μm. The epoxy resin anti-corrosion coating refers to a coating prepared by adding a certain amount of pigments, fillers, additives and solvents with epoxy resin as a film-forming substance. Since the epoxy resin molecular structure contains highly polar hydroxyl groups and ether bonds, the coating has good chemical resistance, good alkali resistance and better heat-resistant alkaline medium.

[0026] By adding a reinforcement layer 3 and a corrosion-resistant layer 4 to the outer surface of the aluminum radiator, the corrosion resistance of the radiator is further improved, avoiding corrosion damage after long-term use, thereby ensuring the normal operation of the radiator and easy use.

[0027] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
