Abstract
The utility model discloses a heat radiator for utilize direct pressfitting power component of shell, including shell and a plurality of power component, the shell includes the epitheca body and casing down, and upper and lower casing fixation is gone up the casing or is equipped with a plurality of archs on the inner wall of casing down together, and ann is cased for the power component, its one side and last shell or protruding counterbalance the on the casing down, another side and last shell or the directly counterbalance of inner wall of casing down. Perhaps set up step on the casing at last casing under or, set up a plurality of archs again on the step.
Description
Technical field
The utility model is related to a kind of heat abstractor of power component, more particularly to one kind directly presses power using shell
The heat abstractor of element.
Background technology
Electric bicycle controller typically can all have the power heater element of more than 6 due to the requirement of power.From its peace
From the point of view of the mode of dress, traditional way is that each power heater element screw is installed in corresponding metal heat-dissipation block, with
Realize the derivation of heat.With the rising of controller power grade, the quantity of power heater element also can increase therewith, therewith band
The cost of labor in production come also can accordingly increase, and the higher contradiction of output is more protruded.
In traditional power heater element mounting means, the cooling surface contacts of power heater element are single-contact,
The conduction of heat can only be shed by the shell of directly contact power heater element, along with shadows such as the waterproof sealing gaskets in shell
The factor for ringing heat conduction is present, and the heat transfer efficiency of power heater element is not high.
And, using traditional screw mounting means in, the temperature difference in temperature and metal heat sink on radiating surface can compare
Larger, especially instantaneous temperature difference, when the heat that so a certain degree of can affect controller under heavy load impacts energy is born
Power, so as to affect controller in power heater element and controller service life.
Utility model content
Goal of the invention：For problem above, the utility model proposes a kind of utilization shell directly presses dissipating for power component
Thermal, radiating efficiency is higher.
Technical scheme：For achieving the above object, the technical scheme that the utility model is adopted is a kind of direct using shell
The heat abstractor of pressing power component, including shell and some power components；The shell includes upper shell and lower house, up and down
Together, the inwall of upper shell or lower house is provided with some projections to housing fixing assembling, and power component is arranged on inside the shell, its
Simultaneously offset with upper shell or the projection on lower house, another side directly offsets with the inwall of upper shell or lower house.Or
Step is set on upper shell or lower house, then some projections are set on step.
Beneficial effect：The heat abstractor causes power component double contact metal shell, realizes sufficient heat conduction and dissipates
Heat, changes the mode of traditional power component single-contact radiating, increases the area of dissipation of power component directly contact, from
And improve radiating efficiency；The fixing assembling of power component is realized while fixing assembling shell, is changed traditional straight
The mounting means with screw lock power component is connect, without with screw installation power element, improve production efficiency.
Description of the drawings
Fig. 1 is the structural representation of upper shell；
Fig. 2 is the side view of heat abstractor；
Fig. 3 is the front view of heat abstractor.
Specific embodiment
The technical solution of the utility model is further described with reference to the accompanying drawings and examples.
As illustrated in fig. 1 and 2, utilization shell described in the utility model directly presses the heat abstractor of power component, including
Shell 1 and some power components 2, shell is made up of die casting aluminium.Shell 1 is made up of upper shell 3 and lower house 4, upper shell 3 or under
Housing 4 is provided with some raised 5.Illustrated as a example by arranging raised 5 on upper shell 3 below.
The Position Design some raised 5 of correspondence power component 2 assembling on upper shell 3, or the first correspondence on upper shell 3
The position of the assembling of power component 2 arranges step 7, then arranges some raised 5 on step 7.During assembling, the one side of power component 2
Contact with raised 5, another side is directly contacted with lower house 4, upper-lower casing passes through the fixing assembling of screw 8 together, directly by work(
Rate element 2 is pressed together between upper and lower aluminum enclosure, to realize two-sided all directly contacts metal shell of power component 2, with sufficient
Heat conduction and radiating.Enable the heat of power component 2 is rapidly derived by metal shell, changes traditional power component 2
The mode of single-contact radiating, increases the area of dissipation of the directly contact of power component 2, radiating efficiency is improve, so as to also carry
The ability of thermal shock is born during the instantaneous heavy load of high controller.
As shown in figure 3, being additionally provided with high temperature resistant silicon glue gasket 6 between raised 5 and power component 2, for buffering power is compressed
Element 2, the thickness 1.5mm of silica gel pad 6 or so, more than 200 degree of high temperature resistant.Water-proof silica-gel pad 9 is lined between upper-lower casing, so
Afterwards with four fixing assemblings of screw 8, power component 2 is pressed together on the mounting plane of shell while assembling shell, was both realized
The abundant radiating of power component, saves the mounting screw of power component again, improves the installation effectiveness of controller.
