Would generally be provided with more than one power device on household electrical appliance, for example, heavy-duty diode, IGCT, GTO,
IGBT etc..Because the voltage and current grade of power device is generally higher, power device can produce substantial amounts of heat when working.Cause
This, power device needs to be connected with radiator so as to take away the heat that power device is discharged in time.
The radiating subassembly 100 of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 7.Such as Fig. 1-Fig. 3, figure
Shown in 5- Fig. 7, radiating subassembly 100 according to embodiments of the present invention can include：At least two radiators 10 and insulated connecting piece
20。
Specifically, be respectively equipped with each radiator 10 first connecting portion 16 and or second connecting portion 21.Insulated connecting piece
20 be provided be suitable to first connecting portion 16 and or the second connecting portion 21 that is connected of second connecting portion 21 and or first connecting portion
16, two neighboring radiator 10 is connected by insulated connecting piece 20.In other words, as shown in Figures 2 and 3, two neighboring radiator
10 when being provided with first connecting portion 16, and the both sides of insulated connecting piece 20 can be provided with the second company being connected with first connecting portion 16 respectively
Socket part 21；As shown in figure 5, when adjacent heat radiation device is provided with second connecting portion 21, the both sides of insulated connecting piece 20 can be provided with and the
The connected first connecting portion 16 of two connecting portions 21；As shown in Figure 6 and Figure 7, two neighboring radiator 10 is provided with the first company
Socket part 16, when another radiator 10 is provided with second connecting portion 21, the both sides of insulated connecting piece 20 are respectively equipped with to be connected with first
The connected second connecting portion 21 in portion 16 and the first connecting portion 16 being connected with second connecting portion 21.
As shown in figure 1, only setting a power device 30 on each radiator 10, it is provided between adjacent radiator 10 exhausted
Edge connector 20.That is, the quantity of radiator 10 and not always fixation, radiating subassembly 100 can include two or two
Radiator 10 more than individual, the quantity of radiator 10 are consistent with the quantity of power device 30.
The shape and structure of each radiator 10 also and not always identical, can come flexible according to the structure of power device 30
Setting.Power device 30 assembles with corresponding radiator 10 and then is connected multiple radiators 10 by insulated connecting piece 20
Pick up to form overall radiating subassembly 100, then radiating subassembly 100 can be integrally mounted on household electrical appliance.Radiating group
When part 100 is dismantled, whole radiating subassembly 100 can be disassembled from household electrical appliance, can also be individually by radiating element 10
Disassembled from household electrical appliance.Wherein, radiator 10 can be connected shaping with insulated connecting piece 20 by way of clamping, dissipate
Hot device 10 can also be integrally formed with insulated connecting piece 20 by way of thermal welding, it is to be understood that aforesaid way is only
Schematically, limitation to the embodiment of the present invention is not it.
Due to being provided with insulated connecting piece 20 between radiator 10, so, no longer needed between radiator and 10 power devices 30
Insulation spacer can is set to avoid forming short circuit connection between the bare electrode of power device 30, and due to power device 30
Surface there is no insulation spacer attaching, increase the contact area of power device 30 and radiator 10, improve power device 30
Radiating efficiency.
In addition, bare electrode can generally be made up of the good heat conductivities such as copper, aluminium or silver and the small material of thermal resistance, exposed electricity

Heat rapidly and efficiently outwards distribute.Thus, the radiating efficiency of power device 30 is further improved.
In one particular embodiment of the present invention, the section of the first noumenon 141 can substantially be formed as rectangle, Duo Ge
One fin 142 is opened in first along the length direction of the first noumenon 141 (such as Fig. 2 and Fig. 3 left and right directions) interval respectively
The same side (such as Fig. 2 and Fig. 3 downside) of body 141, first connecting portion 16 are located at neighbouring second body 152 of the first noumenon 141
One end, the second body 152 can be formed generally as L-shaped with section, and multiple second fin 153 are respectively provided at the second body
152 the same side, the second body 152 include mutually perpendicular first leg 152a and the second leg 152b, first connecting portion 16
It is located at the outside (i.e. the side relative with the first noumenon 141) of the first leg 152a free end, the first noumenon 141 and first
Pin 152a is vertically connected.Plane and the plane at place on the outside of the first leg 152a i.e. where the first noumenon 141 are mutually perpendicular to.
It should be noted that " section " referred to herein refers to the section of radiator above-below direction.The first noumenon 141 and
The opposite side (such as Fig. 2 and Fig. 3 upside) of two bodies 152 can be provided with installation portion (not shown), power device 30 and installation
Portion connects.Fin is located to the same side of the body 152 of the first noumenon 141 and second can improve the letter of the structure of radiating subassembly 100
Clean property, it is easy to the assembling of whole radiating subassembly 100 and household electrical appliance so that it is more reasonable that household electrical appliance internal structure is set.
Alternatively, such as Fig. 2 and Fig. 3, shown in Fig. 5-Fig. 7, the first fin 142 and the second fin 153 be arranged in parallel.By
This, can be in order to the processing and manufacturing of radiator 10 so that the more rational and orderly of the overall construction design of radiating subassembly 100.
In one particular embodiment of the present invention, mounting groove is formed as necking groove, and the section for installing convex tendon forms and pacified
The shape of tankage is corresponding, thickness direction insertion mounting groove of the installation convex tendon along mounting groove.Thus, it is possible to effectively by radiator 10
Upper end is fixedly connected with insulated connecting piece 20.Wherein, installation convex tendon may be integrally formed with insulated connecting piece 20, such as logical
Jetting formation process is crossed to be integrally formed.
Advantageously, the two bottom sides of insulated connecting piece 20 are respectively equipped with the branch of the fin suitable for avoiding and supporting radiator
Support step 22.As shown in figure 3, the lower surface of fin is only butted on supporting step, thus, it is possible to effectively by under radiator 10
End is fixedly connected with insulated connecting piece 20, improves radiator 10 and the connective stability of insulated connecting piece 20.
Alternatively, on the thickness direction of radiator 10, a side surface of insulated connecting piece 20 and installation convex tendon protrudes from
One side surface of radiator 10 stretches out.
Wherein, the thickness direction of radiator 10 refers to perpendicular to direction where Fig. 2 and Fig. 3, Fig. 5-Fig. 7 paper, insulation
One side surface of the side surface and radiator 10 of connector 20 and installation convex tendon refers to the side surface perpendicular to paper upwards,
That is, a side surface of insulated connecting piece 20 and installation convex tendon is extending upwardly from more than radiator 10 relative to paper
A side surface be extending upwardly from relative to paper.It is possible thereby to two neighboring radiator 10 is avoided due to the effect of dust
It is and short-circuit.
