Description
Technical field
It the utility model is related to machine field, more particularly to a kind of natural air cooled motor case of electric car.
Background technology
For the power of motor on electric car in below 10kw, radiating mode is usually the rotating shaft in rear end cap
External part installs a fan blade and carries out air blast cooling.And the most of of more than 10kw are by the way of water cooling.
Cost increase to motor by the way of air blast cooling is not too many, but the noise of motor operation is added very
It is more；Secondly, required the expenditure of energy because fan blade rotates, so air blast cooling can also reduce the operational efficiency of motor；Furthermore because of fan housing
The larger share of motor cumulative volume is occupied, therefore air blast cooling can increase considerably the volume of motor.
It is no doubt preferable to motor radiating effect using water-cooling pattern, but water cooling machine casing of motor complex manufacturing, manufacture
Cost is very high, on electric car, also to increase a set of water cooling facility, so can increase considerably motor using water-cooling pattern
The system cost of manufacturing cost and electric car.Therefore, water can not be used for the motor electric car for only needing below 10kw
Cold mode is to motor radiating.
Also, as shown in Fig. 2 existing motor of electric motor car casing, radiation rib is in " 1 " font, collision easily deforms,
Reduce radiating effect.
Utility model content
Technical problem to be solved in the utility model, which is to provide one kind, to be cooled down under field conditions (factors), be allowed to meet electricity
Machine temperature increase requirement, and a kind of natural air cooled motor case of electric car of structural strength can be improved.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of natural air cooled motor case of electric car, including in the shell body of hollow tube-shape, to shell body both ends
The end cap and the radiation rib on shell body outer wall sealed, it is characterised in that：The radiation rib is along casing
Housing axis direction is set, and the radial structure centered on shell body axis, and the longitudinal section of the radiation rib is in " T "
Font, including horizontal rib and vertical radiating part, the radiation rib is in shell body every 6-6.5mm arc length
One is provided with, radiating gap is provided between the horizontal rib of adjacent two radiation rib.
Further technical scheme is：The vertical radiating part thickness of the radiation rib is 1-1.5mm.
Further technical scheme is：The vertical radiating part thickness of the radiation rib is 1.2mm.
Further technical scheme is：The height of the radiation rib is 10-15mm.
Further technical scheme is：The height of the radiation rib is 12mm.
It is using beneficial effect caused by above-mentioned technical proposal：
(1) in terms of radiating effect, there is the characteristics of ultra-thin and intensive because radiation rib is set, muscle piece quantity is than similar production
The casing of the equal size of product more 60-70%, so it is 55% left under equal conditions to be shed more than heat using the motor of this casing
The right side, motor operation temperature rise is low 12-15 °, and the driving motor of electric vehicle for solving below 10kw must be dissipated using fan blade air blast cooling
The problem of hot, motor remove fan blade, reduce the volume of motor, reduce cost, have good practical value；
(2) noise of motor operation substantially reduces, and improves the performance of motor, electric car is become in the process of moving more
Peace and quiet, improve the usage comfort of drivers；
(3) due to eliminating motor blower fan, the electric energy required for fan blade operation is saved, improves the operation effect of motor
Rate；
(4) the horizontal rib of " T " font radiation rib improves the intensity of radiation rib, and collision in use becomes
Shape amount is smaller.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of motor case in the prior art.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those skilled in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be different from other manner described here using other to be implemented, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.
As shown in figure 1, a kind of natural air cooled motor case of electric car, including in the shell body 1 of hollow tube-shape, to machine
The end cap and the radiation rib 2 on the outer wall of shell body 1 that the both ends of shell housing 1 are sealed, the radiation rib 2 is along machine
The axis direction of shell housing 1 is set, and the radial structure centered on the axis of shell body 1, the longitudinal section of the radiation rib 2
In " T " font, including horizontal rib and vertical radiating part, the radiation rib 2 in shell body 1 every 6-
