Description
Technical field
the utility model relates to a kind of drive unit of air cooled chiller.
Background technique
at present, generally use cooler in construction machinery industry, for the hydraulic pressure wet goods of the circulating water of cooled engine and pressurized air, hydraulic system, and general employing forced to intersect convection heat exchange mode and carried out cooling.Corresponding cold fluid is generally cooling air, and provides the mode of cooling air to be generally referred to as the driving mode of cooler.
in prior art, the design of main flow is at the main shaft of motor or water pump front end assembling fan, provides cold fluid by the mode of air draught or air-supply to cooler, and this design is spindle fan; In another mode, configuration driven module separately, as configuration fluid motor-driven fan, this liquid wind dispelling fan that is referred to as, is also the most general design.
but engineering machinery main frame substantially all belongs to walking arrangement, the power when power resources that cooler generally uses are moved for motor or the power of hydraulic pump drive motor.The power of above-mentioned two kinds of power resources is comparatively abundant, reliability is stronger, but noise is large, power consumption large, position limits to, maintenance difficulty.Especially along with America and Europe constantly upgrade discharge pressure standard, if can not reduce energy consumption and the noise of complete machine, product cannot be sold at European & American Market so.
Summary of the invention
for the problems referred to above, the purpose of this utility model is to provide a kind of drive unit of air cooled chiller, and its energy consumption is low, noise is little.
for solving the problems of the technologies described above, the utility model adopts following technological scheme:
a drive unit for air cooled chiller, described air cooled chiller comprises storage battery, and described drive unit comprises wind scooper, is arranged at one or more DC fan on described wind scooper, and described DC fan is electrically connected mutually with described storage battery.
preferably, described DC fan is removable installed on described wind scooper.
preferably, described drive unit also comprises the controller for controlling described rotating speed of DC fan.
more preferably, described drive unit also comprises multiple for picking up the temperature transducer of temperature information of hot fluid to be cooled, and described temperature transducer is electrically connected mutually with described controller.
more preferably, described DC fan is multiple, and described controller is electrically connected to control respectively the rotating speed of each DC fan mutually with each DC fan.
the utility model adopts above structure, and tool has the following advantages compared to existing technology:
1, replace spindle fan and liquid wind dispelling fan in prior art by DC fan, DC fan power is lower, and energy consumption is low, energy-saving and emission-reduction; DC fan self noise is lower than mechanical type fan, and noise is little; DC fan flexible arrangement, cooler can not be arranged on the front-end face of motor, can be placed on the arbitrary position of vehicle frame, flexible design, and due to away from motor, be beneficial to flowing of cooling air, can avoid the launched machine double heating of cooling air, promoted to a certain extent the cooling effectiveness of cooler.
, the temperature information that picks up according to temperature transducer of controller controls the rotating speed of each fan, the temperature of fluid to be cooled (as temperature, water temperature, oil temperature etc.) is controlled to the optimum temperature needing, energy-saving and emission-reduction; DC fan is moved or is not moved by its slow-speed of revolution of controller control in part-time, and noise is far below mechanical type fan.
, DC fan is single detachable, very convenient in the time of the later stage of cooler complete machine maintenance, do not need to dismantle a large amount of auxiliaries as mechanical type fan and carry out maintaining with vacating space.
Brief description of the drawings
accompanying drawing 1 is stereogram of the present utility model;
accompanying drawing 2 is plan view of the present utility model.
wherein, 1, wind scooper; 2, DC fan.
Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be those skilled in the art will recognize that, protection domain of the present utility model is made to more explicit defining.
the present embodiment is a kind of drive unit of air cooled chiller, and this air cooled chiller has storage battery, for providing the generator of electric power to described storage battery and for controlling the control gear of whole air cooled chiller operation.
shown in Fig. 1 and Fig. 2, the drive unit of described air cooled chiller comprises wind scooper 1, is arranged at one or more DC fan 2 on described wind scooper 1, and described DC fan 2 is electrically connected mutually with described storage battery.DC fan is by VDC and electromagnetic induction, thereby becomes mechanical energy to drive fan blade to rotate by electric energy conversion.
in the time of design, first draw cooling air quantity and static pressure requirement according to cooler heat Balance Calculation, with reference to the overall dimensions of cooler, determine the quantity of DC fan 2, then the DC fan 2 that these have been confirmed uniform on wind scooper 1 to reach effect of a mechanical type fan.In the present embodiment, described DC fan 2 is four, and four described DC fan 2 removably arrange (buckle clamping etc.) on described wind scooper 1 and are arranged in equably on wind scooper 1.
described drive unit also comprises the controller for controlling described DC fan 2 rotating speeds.This controller can be the control apparatus arranging separately, can be also the original control gear of common cooler complete machine, is preferably the latter, to avoid cost to increase.
the drive unit of described air cooled chiller also comprises multiple for picking up the temperature transducer (air-temperature sensor, cooling-water temperature sensor, oil temperature sensor etc.) of temperature information of hot fluid to be cooled (hot water, deep fat, hot blast etc.), and described temperature transducer is electrically connected that with described controller the temperature information picking up is sent to controller mutually.
described controller is electrically connected to control respectively the rotating speed of each DC fan 2 mutually with each DC fan 2, particularly, controller is controlled the rotating speed of each DC fan 2 according to the temperature information receiving, the rotating speed of each DC fan 2 can be different, specifically determines according to the heat distribution situation of fluid to be cooled.
above-described embodiment is only explanation technical conceive of the present utility model and feature; it is a kind of preferred embodiment; its object is that person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to Spirit Essence of the present utility model or modification, within all should being encompassed in protection domain of the present utility model.
