Abstract

The present invention discloses a method for casting heat radiators, which has the technical scheme that the method for casting heat radiators comprises: heat-radiation toothed sheets with required shape, required thickness, required length and required width are prepared; the heat-radiation toothed sheets are arranged on a shim plate; meanwhile, a heat-demanding filling material is filled between every two heat-radiation toothed sheets, and a casting space is formed above the heat-radiation toothed sheets so as to make a casting mould; liquid metal with high temperature is filled in the casting mould, and a small quantity of the parts exposed out of the filling material on the heat-radiation toothed sheets are melted and quickly welded with the liquid metal to coagulate into an integral body so as to make the heat radiator. The heat radiator made by the method of the present invention can meet the requirements for various matching proportions of length, breadth, height, thickness and density, and therefore, can well adapt to the market.

Description

The casting method of radiator

The present invention relates to a kind of radiator, especially the radiator on the high-power electric appliance.

Existing radiator adopts the pressure casting process one-shot forming mostly, owing to be subjected to the restriction of plant equipment and extrusion ratio, ratio between the whole length and width in gear piece thickness, length, density and the cross section of radiator is restricted, do not satisfy the diversity demand of market to the radiator specification, and one-time formed radiator, one mold can only be suppressed a kind of product of specification, and the remodeling cycle is long, and expense is big.

The objective of the invention is: the casting method that a kind of radiator is provided, make radiator in this way, can satisfy various lengths, thick, close blend proportion requirement, have that volume is little, power is big, lightweight advantage, and change shape and specification very easy, have good market adaptability.

The technical scheme of the casting method of radiator of the present invention comprises the steps:

A). get the heat radiation gear piece ready according to required form, thickness and length and width;

B). the gear piece that will dispel the heat is arranged on the backing plate, fills out filler simultaneously between each heat radiation gear piece, and makes the top of heat radiation gear piece expose the filler certain-length, and forms certain casting space on heat radiation gear piece top, so promptly makes the cast model;

C). high temperature fluent metal is injected the cast model, a little fusing of part that the heat radiation gear piece exposes filler, and very fast in aggregates with the liquid metal welding, then made radiator.

Make radiator with aforesaid casting method, the optional material of selecting different thickness of heat radiation gear piece, get the raw materials ready by cutting out, avoided the conventional extruded moulding process to be subjected to the restriction of plant equipment and extrusion ratio, shape, thickness and the length and width of heat radiation gear piece almost can be arbitrarily; Its arrangement mode is also very flexible, is not subjected to the restriction of conventional fixed mould.Therefore can satisfy various lengths, thick, close blend proportion requirement.When adopting not only thin but also high heat radiation gear piece, simultaneously it as far as possible during dense arrangement, can be increased the area of dissipation of unit volume to greatest extent, thereby have that volume is little, power is big, lightweight advantage.Because this technology does not have the mould of solid shape and structure, the cast model can be made flexibly, thereby remodeling is very easy, and market adaptability is strong.

The present invention is further described below in conjunction with drawings and Examples.

The radiator sectional view of Fig. 5 for making with cast model shown in Figure 4.

Embodiment 1:

The casting method embodiment 1 of radiator as depicted in figs. 1 and 2, its operating procedure is as follows:

A). get aluminium alloy heat radiation gear piece 1 ready according to required form, thickness and length and width;

B). the gear piece 1 that will dispel the heat is arranged on the backing plate 5, has certain plastic mixture of forming by quartz particles, clay and water in 1 filling of each heat radiation gear piece simultaneously, and make the top of heat radiation gear piece 1 expose quartz particles 2 certain-lengths, and form certain casting space 4 on heat radiation gear piece 1 top, so promptly make the cast model;

C). high-temperature liquid state aluminium alloy 3 is injected the cast models, and radiator has then been made in a little fusing of part that heat radiation gear piece 1 exposes described mixture, and very fast and liquid aluminium alloy 3 weldings and condense in aggregatesly.

After the cast, mixture is subjected to temperatures involved, knocks gently promptly to revert back to the discrete particles shape, and the demoulding is easy, can use repeatedly.

The later radiator of the demoulding becomes the substrate of radiator as shown in Figure 2 after the liquid alloy condensation of the casting space 4 on model top.

The main effect of the filler of being made up of quartz particles, clay and water is, the one, and with heat radiation gear piece 1 location, the 2nd, form casting space.

Quartz particles can also can adopt synthetic quartz sand for common river sand, lake sand.Binding agent is gone back organic binder bonds such as usable resins except that available clay.

Embodiment 2:

The casting method embodiment 2 of radiator as shown in Figure 3, its operating procedure is as follows:

B). the gear piece 1 that will dispel the heat is arranged on the backing plate 5, put a rigid clip 7 in each 1 bottom of heat radiation gear piece simultaneously, on rigid clip 7, fill again and have certain plastic mixture of forming by quartz particles, clay and water, and make the top of heat radiation gear piece 1 expose the mixture certain-length, and form certain casting space 4 on heat radiation gear piece 1 top, so promptly make the cast model;

C). high-temperature liquid state aluminium alloy 3 is injected the cast models, and radiator has then been made in a little fusing of part that heat radiation gear piece 1 exposes mixture, and very fast and liquid aluminium alloy 3 weldings and condense in aggregatesly.

The main effect of rigid clip 7 is with heat radiation gear piece 1 location in the present embodiment; The main effect of quartz particles mixture is to form casting space.The benefit of this scheme is to reduce the consumption of mixture, saves the time of preparating mixture, and the locating effect of rigid clip is better simultaneously.Rigid clip can be metal, flag etc.

The filler 2 that the heat radiation gear piece is 1 also can be made up of single rigid clip, owing to its top directly contacts with metal liquid, thereby needs to adopt resistant to elevated temperatures material, generally uses resistant to elevated temperatures metal.

The effect of backing plate 5 mainly is supporting heat radiation gear piece 1 and filler therebetween, and the effect to heat radiation gear piece 1 location is also arranged simultaneously, makes the lower end of the gear piece 1 that respectively dispels the heat concordant.

The shape of heat-radiating substrate 4 and structure are determined by casting space.The substrate 4 that Fig. 1 and casting space shown in Figure 3 form is a tabular.

As shown in Figure 4, casting space also can extend downward concordant with the lower end of the gear piece 1 that dispels the heat from two ends.After the liquid alloy condensation, except that the substrate 4 that has formed top, the side plate 6 (as shown in Figure 5) that is connected as a single entity with substrate 4 that has also formed both sides.The radiator of this structure has increased the contact-making surface between substrate and the heater, is well-adapted in some occasion.

Whole cast model can place a framework, framework can metal or timber make, can be fixed also can be movable.
