Wherein radiating fin is 5-10mm at a distance from accommodating chamber, and radiating fin distance PTC heater element is closer,
Therefore the temperature in the region of the heat sink where radiating fin is higher, can be arrived the conduct heat away of the part by radiating fin
In battery case, it is ensured that the battery that heat sink contacts it guarantees being uniformly distributed for battery temperature, while can with heating
To distribute heat in battery case, increase the temperature inside the box, and then integrally heat to battery, increases the heating for battery
Uniformity.
Preferably, the both sides of the edge of the heat sink offer several through-holes through the heat sink, the heat sink
The heat release hole of both sides of the edge is arranged between being in, and with the centerline parallel in the heat sink transverse direction.
By for, to which heat sink to be fixed on inside battery case, being fixedly connected with it with battery case across bolt.
Further, the section of the through-hole is ellipse, the long axis and the heat sink of the ellipse hole
Centerline parallel in transverse direction.
The through-hole of ellipse makes when heat sink is fixed on battery case with bolt, carries out to the position of heat sink micro-
It adjusts, to overcome the error in thread mill drilling on battery case, guarantees the accuracy of the relative position of heat sink and battery.
Preferably, the heat sink is integrally formed setting.
Further, the heat sink is aluminium or aluminum alloy material.
Integrally formed aluminium or aluminium alloy heat sink have lower thermal resistance, and heat transfer efficiency is higher.
The principles of the present invention, effect are further illustrated below with reference to above-mentioned technical proposal:
The heat sink of the utility model is set in battery case, is in contact with the battery in battery case, and PTC heater element is logical
It crosses conducting wire to be electrically connected with the power supply, the heat that the PTC heater element after powering on issues can pass to heat sink, then pass through again
Battery is passed to by heat sink, battery of the heating in low temperature environment guarantees the normal work of battery；And since PTC generates heat
Element thermal resistance is small, heat exchange efficiency is high, is a kind of electric heater of automatic constant-temperature, therefore the application has easy control of temperature, makes
With the beneficial effect of safety.
