Abstract
The utility model discloses an electric vehicle temperature adjusting device. The electric vehicle temperature adjusting device comprises a driving motor, a motor controller, an air conditioning compressor, an electric control valve, a temperature sensor, a water pump, a radiator, a pipeline and the like. The flow direction of cooling water is adjusted by controlling the electric control valve, three different forms of cooling circulation can be realized, and the consumption of electric energy can be effectively reduced when part of parts is not required to be cooled; meanwhile, by reasonably arranging the arrangement sequence of radiating parts, the problems of uneven radiation and the like caused by difference of heat radiation amount can be solved, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to a kind of automobile-used temperature control equipment, and especially a kind of elec. vehicle temperature control equipment belongs to the electric vehicle engineering field.
Background technology
Elec. vehicle has adopted high-power parts such as drive motor, controller, air-conditioning compressor, and these parts can produce a large amount of heat energy in operational process, for guaranteeing its reliability of operation; Usually needing increases cooling system, and traditional way is with a plurality of unit Series together, adopts a cover cooling system to cool off; Yet this way can be brought two problems, the first, and various parts degree of heat radiation is variant; For example the big heat radiation of engine power is bigger; The little heat radiation of controller power is also little, causes controller not only can not obtain better radiating effect after adopting a cover system, also might be opposite; In addition, some parts possibly not used always, does not just need work like air-conditioning compressor in winter, adopts the load that has increased water pump after this system, the waste power supply.
The utility model content
The purpose of the utility model is: the problem to above-mentioned prior art exists, a kind of elec. vehicle temperature control equipment is proposed, and can realize the part parts are cooled off and adjustment, avoid because the uneven problem of the heat radiation that the difference of heat dissipation capacity causes.
In order to reach above purpose; A kind of elec. vehicle temperature control equipment of the utility model; The pipeline that mainly comprises drive motor, electric machine controller, air-conditioning compressor, electric control valve, water pump, radiator and be used for each parts is linked to each other; Said electric control valve comprises three automatically controlled triangle valves; Said radiator connects water pump, drive motor and first electric control valve successively through pipeline, and second interface of said first electric control valve inserts said radiator successively with said electric machine controller, second electric control valve, air-conditioning compressor with after the 3rd electric control valve links to each other through pipeline; The 3rd interface of said first electric control valve and the 3rd interface of said second electric control valve insert the 3rd interface of said the 3rd electric control valve after pipeline is parallelly connected.
It is that aforesaid elec. vehicle temperature control equipment is provided with temperature sensor in the water outlet port of said drive motor, electric machine controller and air-conditioning compressor that the utility model further improves; Be provided with temperature sensor in said radiator water inlet port.
The parts of the three kinds of needs cooling in the utility model be according to from cooling water expansion tank to drive motor; Electric machine controller; Again to air-conditioning compressor, purpose be because air-conditioning compressor be not use always, electric machine controller is less in the low temperature environment heat radiation, can close its heat-radiation loop.
The beneficial effect of the utility model is: the humidity control system of the utility model, can realize three kinds of multi-form cooling circulation, and when the part parts need not cool off, can effectively reduce power consumption; Simultaneously,, can avoid because the unequal problem of heat radiation that the difference of heat dissipation capacity causes, prolong the service life of product through the distributing order of reasonable Arrangement heat radiation part.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the schematic diagram of the utility model.
The specific embodiment
Embodiment one
The elec. vehicle humidity control system of present embodiment; Its principle is shown in Figure 1, comprises drive motor 1, electric machine controller 2, air-conditioning compressor 3, first electric control valve 6, second electric control valve 7 and the 3rd electric control valve 8, water pump 5, radiator 4 and four parts such as temperature sensor 9,10,11,12.Electric control valve is a triple valve, and A, B, three ports of C are all arranged, and promptly the circulation style of each triple valve has two kinds of A → B and A → C, realizes flowing to and regulates through controlling its valve; Temperature sensor in the present embodiment has four, is installed in the water side of drive motor 1, electric machine controller 2, air-conditioning compressor 3 and the water inlet end of radiator 4 respectively.
The humidity control system cooling water expansion tank has three kinds of circulation styles: (1) radiator 4 → water pump 5 → drive motor 1 → the first electric control valve 6 → electric machine controller 2 → the second electric control valves 7 → air-conditioning compressor 3 → the 3rd electric control valve 8 → radiatores 4; (2) radiator 4 → water pump 5 → drive motor 1 → the first electric control valve 6 → electric machine controller 2 → the second electric control valves 7 → the 3rd electric control valve 8 → radiator 4; (3) radiator 4 → water pump 5 → drive motor 1 → the first electric control valve 6 → the 3rd electric control valve 8 → radiator 4; Described three kinds of circulation styles, be the temperature signal of gathering by four temperature sensors after, control through electric control valve.
The parts of drive motor 1, electric machine controller 2 and air-conditioning compressor 3 these three kinds of needs coolings are according to from cooling water expansion tank to drive motor 1; Electric machine controller 2; Again to air-conditioning compressor 3; Purpose be because air-conditioning compressor 3 be not use always, electric machine controller 2 is less in low temperature environment heat radiation, can close its heat-radiation loop;
Except that the foregoing description, the utility model also can have other embodiments, and the parts that for example need cool off have more than three.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
