Abstract
The utility model discloses a laminated radiator, which comprise a plurality of laminations mutually welded. Each lamination comprises a radiating fin, a first building-block type splice head and a second building-block type splice head, wherein the first building-block type splice head and the second building-block type splice head are respectively arranged on the lower portion and the upper portion of the radiating fin, the width of the radiating fin is smaller than those of the first building-block type splice head and the second building-block type splice head, bumps are respectively arranged on two sides of the first building-block type splice head and two sides of the second building-block type splice head, and the bumps on the two sides of the first building-block type splice head and the two sides of the second building-block type splice head correspond to bumps on two sides of an adjacent blocking-building type splice head. The laminated radiator has the advantages of simple structure and high radiation performance.
Description
Technical field
The utility model relates to a kind of stacked radiator, is a kind of heat abstractor that is used for high power electronic equipment.
Background technology
Along with development of modern industry, the use of power electronic equipment is universal day by day.The power electronics manufacturing becomes an independently subject gradually.Power electronic equipment is based on power model.Power model is the operating part of whole device, must the guaranteed output module be in a suitable operational environment when therefore installing work.The parameter that influences the power model performance mainly contains: DC bus-bar voltage, operating current, PN joint temperature and switching frequency.In general, DC bus-bar voltage, operating current and switching frequency, we can control by control method, and PN joint temperature is except with also relevant with the performance of radiator control method is relevant.Power model also is electric semiconductor, is to utilize its different state: turn on and off, reach different performance requirements.Because power model is not desirable switch element, so element has the certain power loss when turning on and off, and sends with the form of heat.Power model all has the upper limit of its working temperature, if surpass temperature upper limit, and the module controlled decline or uncontrollable that will become, so the heat that power model is sent is in time derived, so radiator must have good performance.The large-scale power electronic installation adopted fin-inserted radiator mostly in the past, and this radiator adopts the mode of pedestal and inserted sheet combination, and is simple in structure, made easily.Yet this radiator has its unavoidable defective.Have a large amount of spaces in the junction of inserted sheet and pedestal, we know that the heat-conducting effect of air is far smaller than metal, has so just hindered heat and has been transmitted on the inserted sheet by pedestal.In order to strengthen the performance of this radiator, between inserted sheet and pedestal, fill heat-conducting glue.This can increase heat dispersion to a certain extent with mode, but the thermal conductivity of heat-conducting glue still is far smaller than metal, and effect is limited.
The utility model content
The utility model purpose is to provide a kind of stacked radiator to be used to replace traditional fin-inserted radiator at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The stacked radiator of the utility model, it is characterized in that: comprise that several laminations are welded to each other formation, each lamination all comprises fin, the first cordwood system type spelling joint and the second cordwood system type spelling joint, wherein the first cordwood system type spelling joint and the second cordwood system type spelling joint are arranged at the bottom and the top of fin respectively, the width of fin is less than first, the width of the second cordwood system type spelling joint, the both sides of the first cordwood system type spelling joint and the second cordwood system type spelling joint are provided with projection respectively, and described first, the projection of the second cordwood system type spelling joint both sides is corresponding with the projection of adjacent cordwood system type spelling joint both sides respectively.
The utility model is simple in structure, and heat dispersion is than the fin-inserted radiator height.
Description of drawings
Fig. 1 is stacked radiator monolithic lamination figure.
Fig. 2 is lamination radiator integral figure (overlooking).
Fig. 3 is stacked radiator front view and work signal thereof.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to utility model:
As shown in Figure 1, special aluminium sheet is made as shown in the figure element, be made into a plurality of laminations, and it is stitched together.Each lamination all comprises fin 1, the first cordwood system type spelling joint 2 and the second cordwood system type spelling joint 3, wherein the first cordwood system type spelling joint 2 and the second cordwood system type spelling joint 3 are arranged at the bottom and the top of fin 1 respectively, the width of fin 1 is less than the width of first, second cordwood system type spelling joint 2, the both sides of the first cordwood system type spelling joint 2 and the second cordwood system type spelling joint 3 are provided with projection respectively, and the projection of described first, second cordwood system type spelling joint 2 both sides is corresponding with the projection of adjacent cordwood system type spelling joint both sides respectively.Described stacked radiator: it is characterized in that described whole lamination all adopts aluminium sheet to cast.Described stacked radiator: it is characterized in that described several laminations adopt the argon arc welding.
What we saw among Fig. 2 is the radiator vertical view.As shown in Figure 2, the radiator middle part is a gas channel, and adopts groove design to increase and the air-flow contact area.Adopt the argon arc welding to make it firm between the lamination.Power model is contained in the radiator front surface, as Fig. 3.Adopt the air blast cooling type of cooling during work, make air-flow from bottom to top circulation continuously that radiator heat energy is discharged in the air.Because the unit lamination is the aluminium sheet design of monoblock high thermal conductivity, therefore heat can be delivered to the lamination end rapidly.For guaranteed output module temperature unanimity, the material of lamination must be identical.For lamination can be fitted like a glove, contact is tight, and the making of mould needs accurately, and tolerance surpasses ten thousand/rice.
