The technical field is as follows:
the utility model relates to a machine controller rack test leads to water frock of ventilating, it belongs to new energy automobile machine controller test technical field.
Background art:
the loading test of the motor controller rack is an important link in the production process, and aims to test the loading capacity of the controller. When the controller is loaded to the peak current (taking SMC350 as an example, the peak current 530A) during the test, the power device IGBT generates a large amount of heat and needs cooling liquid supplied from the outside for heat dissipation. The working principle is that cooling liquid flows into a water channel through a water pipe arranged on a water nozzle of the controller and then flows out from an outlet water nozzle through an outlet water pipe to take away heat. The main problems and disadvantages are: 1. the water pipe and the water nozzle are not well matched and are inconvenient to install; 2. the water pipe and the water nozzle need to be fastened through the hose clamp, so that the operation is inconvenient; 3. when the flow of the cooling liquid is large, the joint of the water pipe is easy to leak; 4. residual cooling liquid still exists in the water channel after the test is finished; 5. the water pipe is mounted and dismounted inefficiently.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The utility model has the following contents:
the utility model relates to a solve the problem that above-mentioned prior art exists and provide a machine controller rack test leads to water frock of ventilating, improve the installation and dismantle the convenience, improve production efficiency, it is compatible strong, the coolant liquid flow also can not the seepage when big, can directly blow off after the test and remain the coolant liquid in the water course.
The utility model discloses the technical scheme who adopts has: the utility model provides a machine controller rack test leads to water frock of ventilating, includes machine controller and installs inlet nozzle and faucet on machine controller the inlet nozzle and faucet go up the card respectively and are equipped with inlet nozzle quick-operation joint and faucet quick-operation joint, install first three-way valve and second three-way valve on inlet nozzle quick-operation joint and the faucet quick-operation joint respectively, inlet nozzle quick-operation joint is connected to a mouth of first three-way valve, and first water pipe and first trachea are connected respectively to two other mouths, be connected with first logical water switch on the first water pipe, be connected with first ventilation switch on the first trachea, outlet nozzle quick-operation joint is connected to a mouth of second three-way valve, and second water pipe and second trachea are connected respectively to two other mouths, be connected with second logical water switch on the second water pipe, be connected with second trachea switch on the second trachea.
Furthermore, the first water pipe is a water inlet, the first air pipe is an air inlet, the second water pipe is a water outlet, and the second air pipe is an air outlet.
Furthermore, the first water pipe is connected to the left side of the first three-way valve, the first air pipe is connected to the right side of the first three-way valve, the second water pipe is connected to the left side of the second three-way valve, and the second air pipe is connected to the right side of the second three-way valve.
The utility model discloses following beneficial effect has: the utility model discloses the test of machine controller rack leads to water frock installation of ventilating fast, convenient, connects the fastening, and the coolant liquid flow can not the seepage greatly yet, can bear 10Mpa pressure the most, can effectively clear up after the test accomplishes and remain the coolant liquid in the water course.
Description of the drawings:
fig. 1 is the utility model discloses the schematic diagram of the test of machine controller rack leads to water frock of ventilating.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
