Specific embodiment

Substantive distinguishing features of the present utility model are made further with reference to specification drawings and specific embodiments It is bright.

A kind of pressure-casting type heating block as shown in Figure 1, the heat-generating pipe 2 by heat sink 1 and in heat sink 1 is constituted, The heat sink 1 is fixed on heat-generating pipe 2 by die casting mode so that the stage casing peripheral outer wall of heat-generating pipe 2 is closely pasted with heat sink 1 Close.

In production, realized by following steps：

1. heat-generating pipe 2 is individually produced, in case die casting is used when spreading hot plate；

2. radiating tube is placed in advance in the mould that die casting heat sink 1 is used, Guan Bi mould, in heat-generating pipe 2 and mould The die casting space of die casting heat sink 1 is formed between wall, now, the two ends of heat-generating pipe 2 are spatially separating with die casting；

3. the molten metal press-in die of molten condition will warm up, and now, molten metal will be filled with die casting space, die casting space Interior air completely wraps up the stage casing outer wall of heat-generating pipe 2 by the outer row of molten metal extruding, molten metal；

4. molten metal is cooled down and solidified, opening mold, is completed heat sink 1 and is processed.

Realize that heat sink 1 is molded with the integral die-cast of heat-generating pipe 2 by above-mentioned steps, it is ensured that heat sink 1 and the stage casing of heat-generating pipe 2 It is brought into close contact between outer wall, effectively eliminates gap, and both heat transference efficiencies and bonding strength are lifted with this.

In practical operation, the heat sink 1 is plate-like, vertically communicated thereon to open up densely covered honeycomb hole 3（Such as Fig. 2 institutes Show）.The vertical honeycomb hole 3 for opening up both is effectively increased exposed surface area, moreover it is possible to improve radiating efficiency by increasing air circulation. Separated by tabular interlayer 4 between adjacent cell hole 3, the level of the interlayer 4 is set to uniform thickness.Interlayer 4 both plays the adjacent honeybee of isolation The effect of socket bore 3, plays a part of to transmit heat again, the effect for maintaining the structural strength of heat sink 1 is also acted as, when interlayer 4 is relatively thin When, louvre size is bigger, and exposed surface area is also bigger, but the structural strength of heat sink 1 is weaker and die casting difficulty is bigger, so The thickness of interlayer 4 should be set according to actual conditions, to have good heat dissipation effect concurrently, the characteristics of structural strength is high, be regarded as Specific embodiment of the utility model.

In practical operation, the honeycomb hole 3 is in regular polygon, and honeycomb hole 3 is opened up on heat sink 1 can effectively reduce scattered The weight of hot plate 1, and reduce raw materials consumption.Honeycomb hole 3 is polygon, preferably hexagon, quadrangle etc., facilitates honeycomb hole 3 Arrangement, moreover it is possible to effectively reduce the wall thickness of interlayer 4, be regarded as specific embodiment of the utility model.When honeycomb hole 3 uses positive six side During shape structure, each border of honeycomb hole 3 is equipped with six profile identical regular hexagon honeycomb holes 3, and so on be covered with it is scattered Hot plate.

In practical operation, the heat-generating pipe 2 includes a protection pipe 5 being brought into close contact with heat sink 1, is filled in protection pipe Heating core, plug in 5 are enclosed in the insulating plug 6 at the two ends of protection pipe 5 and place the binding post 7 being connected on insulating plug 6（As schemed Shown in 3）, heating core receives extraneous power supply and generates heat by binding post 7.The heating core includes leading to binding post 7 Heating wire 9 and it is filled in magnesia bisque 10 between heating wire 9 and protection pipe 5.Because protection pipe 5 and heat sink 1 are linked as one Body, when heating core is damaged, the insulating plug 6 for exposing to heat sink 1 by dismounting realizes that heating core is changed, protection pipe 5, insulating plug 6 and binding post it is reusable, effectively reduce maintenance cost.

In practical operation, the heat-generating pipe 2 is by the outer wall of the protection pipe 5 and the close adhesion of heat sink 1, the wiring Terminal 7 exposes to the heat sink 1, and the outer end of binding post 7 is led to extraneous power supply, the inner through after insulating plug 6 with heating core Lead to.Die casting forms the conducting part 8 that matching is wrapped up and attaches protection pipe 5 on the heat sink 1.Molten metal shape in press casting procedure Into the conducting part 8 of the parcel outer wall of protection pipe 5, when condensation forms solid-state heat sink 1, due to principle of expanding with heat and contracting with cold, the meeting of conducting part 8 Lock ring realizes that both are affixed in protection pipe 5.In actual installation, binding post is also used as the installation portion of heating block, makes Obtain heating block to be fixed on default station, moreover it is possible to be separately provided the connection for affixed blackout heating block on heat sink Part, can also realize that heating block is installed, and also should be regarded as specific embodiment of the utility model.

In practical operation, the material fusing point of the material fusing point higher than the heat sink 1 of the protection pipe 5.The protection Pipe 5 is stainless steel, and the heat sink 1 is aluminum alloy material.When the aluminum alloy melt of heating and melting injects die casting space, aluminium Aluminium alloy can because contacted with stainless steel protection pipe 5 and so that stainless steel protection pipe 5 is heated, now, the stainless steel protection pipe 5 being heated Still have the external forces that the structural strength for keeping certain carrys out hardness die casting generation, protect heating core safety.Additionally, except above-mentioned Collocation is outer, and the material of fusing point and Structural strength calls can also be met using other, and such as protection pipe 5 uses ferrous material, dissipates Hot plate 1 also should be regarded as specific embodiment of the utility model using aluminum material etc..

The heat sink 1 is rectangle, and the heat-generating pipe 2 is along the horizontal direction of heat sink 1 through setting, the heat-generating pipe 2 At least two, and be abreast uniformly arranged on heat sink 1 each other.The profile of heat sink 1 should be wanted according to actual installation space Ask and set, the quantity of the heat-generating pipe 2 should determine according to the size of heat sink 1 and profile, because heat transfer can be with Distance increases and loss occurs, in order to ensure each portion's temperature-averaging of heat sink 1 on heat sink 1, it is necessary to be uniformly distributed heating Pipe 2, the utilization ratio in each portion of heat sink 1 is improved with this.
