Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As it is shown in figure 1, this utility model provides a kind of liquid cold control used for electric vehicle, including casing, described housing
Lower house 110 and the upper cover 120 covered on lower house 110 by upper opening form.It is provided with in the bottom of lower box 110
Cooling water channel.
As shown in Figure 2 and Figure 3, described cooling water channel is an entirety from processing technique and actual condition with housing design, makes
Controller entirety is the compactest；Water channel cover plate 130 design is different from the mode of general sealing strip sealing means or argon arc welding, water
Road cover plate 130 uses the welding manner that agitating friction welds, and is welded on the bottom of lower house 110, high degree ensure that sealing
Reliability, do not have the thinnest leakage caused of solder in tradition argon arc welding simultaneously yet or solder too much penetrate into the feelings of water channel
Condition.
Remainder on described housing devises air channel, on the one hand can alleviate controller weight, also enhance simultaneously
The cooling of controller.
As shown in Figure 4, according to housing bottom zones of different can groove depth, the region beyond water channel is according to enclosure interior
The position of screw hole is sat and is dodged fluting accordingly；The jack position of power connectors in housing lateral layout, power connectors
Compact Layout makes controller overall width diminish, and improves power density；Waterproof lock 240 is installed at jack position.
Upper cover 120 is fixed the sinking design of screw and is made whole controller marginal surface smooth.Upper cover 120 is provided with openable
Wiring cover plate 140, the design of wiring cover plate 140 makes to need not open whole upper cover 120 can complete power line wiring.Shell
The design of body surrounding reinforcement adds the intensity of controller housing.
Be disposed with IGBT circuit board 150 in housing from top to bottom, IGBT drives plate 160, barricade 170 and master control
Plate 180.Also include DC-Link electric capacity 190, current sensor 210, exchange bracer 220 and AC copper-line 230.
This utility model is optimized design from the angle of compatible different electric systems to master control borad, it is ensured that right
Various electric systems are the most compatible.The double-core that have employed DSP+CPLD on plate processes framework, and this framework make use of DSP
High-speed figure processes and motor controls advantage, make use of CPLD real-time on fail-safe design, extending out I/O interface
Customizability on interrelated logic, the motility in bus time-sharing reuse plan, ensure that the real-time of control greatly, carry
The high reliability of error protection, makes to be possibly realized multiple electric system compatibility simultaneously.
Controller has been carried out designing targetedly by this utility model from the angle of electromagnetic compatibility.Main topological loop uses thin
Membrane capacitance is as DC-Link, it is provided that ripple current required under each operating mode of controller, for extending battery on electric automobile
Life-span has great benefit；The stack bus bar being connected by between direct current lead-in wire terminal and thin-film capacitor can be to a certain extent
Reduce the stray inductance of commutation circuit；The low sense design of thin-film capacitor and and IGBT between the distance that shortens as far as possible of terminal can
So that stray parameter reduces as far as possible on whole commutation circuit.In addition, Y is devised targetedly at DC-Link end
Electric capacity, devises Absorption Capacitance between DC+, the DC-at IGBT.It is minimum that global design makes stray parameter in loop be down to,
The EMI that the reduction of stray parameter makes electric machine controller overall reduces.The most also reserve at direct current lead-in wire terminal and exchange leading-out terminal
Can install the position of magnet ring, installing additional of magnet ring can make system entirety EMS performance improve.
This utility model makes same master control borad be applicable to the full extent not by rationally and cleverly circuit design
Same electric system；Designed by the optimization of main topological loop, the screening of key components, improve motor control as far as possible
The Electro Magnetic Compatibility of device.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment
Listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art,
It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
It is not limited to specific details and shown here as the legend with description with novel.
