Description
Technical field
The utility model belongs to the power electronic equipment field, is specifically related to relate to a kind of novel thyristor water-filled radiator.
Background technology
Also there is not the similar techniques utility model at present both at home and abroad.6 inches traditional thyristor water-filled radiator runner designs have two kinds of typical designs usually: 1. runner adopts the spiral of Archimedes method for designing, adopts increase diversion column (rib post) to realize strengthening heat convection in the runner.2. runner adopts big cavity method for designing, and arranging multiplayer grid fin is realized fluid three dimensions runner in the runner, to reach the purpose that strengthens heat exchange.
Different runner designs and internal fins arrangement have a significant impact the flow resistance and the resistive properties of radiator, the radiator that first kind of mode designs often has good hot property, the uniform temperature of spreader surface is fine simultaneously, can finely satisfy of the requirement of thyristor element to the heat-delivery surface uniform temperature, but because the flow process that flows is longer, cause resistance bigger, thereby cause converter valve water-cooling system overall presure drop bigger, for the leakage in water route in parallel brings possibility.This radiator is applicable to the cooling situation that flow is less, and under the big condition of flow, fluid needs very high pump pressure by radiator.The radiator that the second way designs just is discharged from radiator but the fluid flows faster has little time abundant heat exchange, thereby has bigger thermal resistance because the complexity and the three-dimensional character of internal flow often have well less flow resistance.In the runner square cavity, four flow dead can occur simultaneously, worsen the local convection heat exchange, higher near the spreader surface temperature of radiator water outlet side in addition, cause the spreader surface temperature non bigger.This radiator is applicable to the cooling situation that flow is bigger, and under the little condition of flow, fluid is low excessively by the radiator flow velocity, and local location heat convection condition is very poor.
The utility model content
The utility model provides a kind of thyristor water-filled radiator runner design of novelty, as shown in Figure 1.The method for designing that this water-filled radiator runner method for designing has adopted helical flow path and grid type fin to combine, this method advantage is that radiator flow resistance and thermal resistance are less, spreader surface temperature uniformity, the abundant heat exchange of internal flow, do not have flow dead and heat local accumulation, thermal resistance and flow resistance performance can be realized by adjusting the spiral channel number of turns and grid fin density according to designing requirement.
A kind of novel thyristor water-filled radiator that the utility model proposes is characterized in that: this radiator comprises helical flow path and is arranged on each interior grid fin of helical flow path that the top angle theta that described adjacent two grid fins constitute is 30 °-90 °.
Wherein, described have the runner of helix and a runner that the multi-layer net fin combines, cooling fluid is from runner one side inflow of helix, after the even shunting of multi-layer net fin and abundant heat-shift that process longshore current road is arranged, thereby compile the zone that cooling thyristor center has maximum temperature in the spiral central area, and then flow out an other side of helix runner along the runner of helix.
Wherein, the described number of plies with the helix number of turns that has in the runner of helix and grid fin can be regulated by heat radiation requirement and traffic requirement, can reduce the helix number of turns and the grid fin number of plies when flow resistance is big, flow resistance hour can increase the helix number of turns and the grid fin number of plies.
Wherein, the number of plies of described grid fin is the 1-5 layer, and thickness is 1-10mm.
The advantage of technical solutions of the utility model is:
1. thermal resistance and flow resistance are little, and the spreader surface uniform temperature is good.
2. applicability is strong: the occasion that can adapt to different heat radiation requirements, different flow requirement.
Description of drawings
Fig. 1 is according to thyristor water-filled radiator flow passage structure schematic diagram of the present utility model;
Wherein, 1-helical flow path, 2-grid fin.
Embodiment
Below in conjunction with accompanying drawing water-filled radiator of the present utility model is described in further detail.
The utility model has mainly carried out the innovation design to 6 inches thyristor water-filled radiators of converter valve runner, mainly is made up of 2 parts shown in Figure 1: helical flow path 1 and grid fin 2.Fluid is from helix runner one side inflow, after the even shunting of grid fin and abundant heat-shift that process longshore current road is arranged, compile cooling thyristor center highest temperature region in the spiral central area, and then flow out the other side of helical flow path along the helix runner.In order to make radiating effect reach best, the top angle theta that adjacent two grid fins form is 30 °-90 °.This runner and fin arrangement have been given full play to the advantage of design of spiral of Archimedes runner and the design of multi-layer net cavity: 1. fluid flows and retrained by the helix runner, can not occur flowing " short circuit " and the insufficient heat exchange of the fluid that brings.2. the runner inner fluid flows and to have avoided single situation about flowing around helix, arrange that by multi-layer net realized the three dimensional fluid eddy flow, promptly fluid not only has the helix circumferential flow in grid, also occurred having strengthened runner heat convection up and down around grid " climbing stream " up and down.3. made full use of the little and little advantage of grid type radiator flow resistance of helical flow path heat radiator thermal resistance, can satisfy thermal resistance and flow resistance requirement under the different flow condition by adjusting the spiral channel number of turns and grid fin density, this radiator runner design scope of application is wide.4. because integral body adopts helical flow path, the spreader surface uniformity of temperature profile can satisfy the requirement of thyristor to the heat dissipation element harshness.
The utility model is described according to specific exemplary embodiment herein.To carry out suitable replacement under the scope of the present utility model or revise will be conspicuous not breaking away to one skilled in the art.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present utility model, scope of the present utility model is by appended claim definition.
