Abstract
The utility model relates to a kind of insulated gate polar form power tube liquid cooling heat radiator used for wind power generation, comprise radiator body and be distributed in the water channel in radiator body, water channel two ends are respectively water inlet and delivery port, water channel is the inside two-tube even side-by-side helix structure of two-port, described helical structure is rectangular, and water channel length is for being greater than 1000mm.Liquid cooling plate out made by the utility model, has low flow resistance, low thermal resistance, the good feature of uniform temperature.
Description
Technical field
The utility model belongs to power electronics cooling technology field, particularly relates to a kind of liquid cooling cooling of high-power insulated gate polar form power tube components and parts, for fields such as air-cooled generatings.
Background technology
The kinetic energy of wind power generation wind becomes mechanical kinetic energy, then is electric power kinetic energy changes mechanical energy, Here it is wind power generation.The principle of wind power generation, is utilize wind-force to drive air vane to rotate, then the speed rotated is promoted through booster engine, impel electrical power generators.According to current windmill technology, be approximately the gentle breeze speed (degree of gentle breeze) of three meters per second, just can start generating.Wind power generation forms one upsurge just in the world, because wind power generation does not need to use fuel, also can not produce radiation or air pollution.Along with the development of novel semi-conductor, the extensive uses on wind power generation after the nineties in 20th century such as IGBT (Insulated Gate Bipolar Transistor, insulated gate polar form power tube).
High-power IGBT (insulated gate polar form power tube) vigour part operationally high, the density of heat flow rate of dissipation power and caloric value large, cause element temperature rise, the q&r of product will be had a strong impact on, therefore the suitable type of cooling must be adopted to dispel the heat to it, liquid cooling, air-cooled, heat pipe, natural cooling radiator are used in the cooling of electric power semiconductor element usually, and wherein liquid cooling comprises water-cooled and oil cooling.In the engineer applied of reality, in order to cooling solution does not freeze in subzero, the general certain proportion glycol water that adopts cools.
Utility model content
The utility model is in order that design a kind of low flow resistance, low thermal resistance, uniform temperature good IGBT liquid cooling heat radiator structure.
The technical solution of the utility model is: comprise radiator body and be distributed in the water channel in radiator body, water channel two ends are respectively water inlet and delivery port, water channel is the inside two-tube even side-by-side helix structure of two-port, and described helical structure is rectangular, and water channel length is for being greater than 1000mm.
The beneficial effects of the utility model are: radiator body water channel is the rectangularl runner of evenly arrangement, adjacent two flow to and are respectively into water and water outlet, hot and cold water alternate cycles, make whole radiator table top uniformity of temperature profile, water route length of spiraling is greater than 1000mm, and cooling fluid flow regime in runner is turbulent flow, heat exchange is abundant, thermal resistance is less, and cross section of fluid channel and discharge matched design, flow resistance is little.By liquid cooling plate out made by the present invention, low flow resistance, low thermal resistance, the good advantage of uniform temperature can be met.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the water channel 3 that the utility model comprises radiator body 1 and is distributed in radiator body, water channel 3 two ends are respectively water inlet 5 and delivery port 4, water channel 3 is the inside two-tube even side-by-side helix structure 2 of two-port, and helical structure 2 is rectangular, and water channel 3 length is for being greater than 1000mm.
Cooling fluid enters radiator body 1 through water inlet 5, and cooling fluid is along the labyrinth path flowing of design, and fluid temperature peak position and lowest point are adjacent.With traditional single channel connect water route radiator compared with, the radiator table top temperature difference is lower, is more conducive to reliability that IGBT (insulated gate polar form power tube) uses and the prolongation in useful life.
The above is only preferred implementation of the present utility model, for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvement, and these improvement also should be considered as protection range of the present utility model.
