The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of hollow cooler for motor, and this cooler can effectively reduce windage, and improves the heat exchange effect.
For achieving the above object, the utility model adopts following technical scheme:
This hollow cooler for motor comprises the wind cabinet, is located at number row's heat exchanger tube in the wind cabinet and the wind-collecting cover of being located at wind cabinet one end, heat exchanger tube one end communicates with outside blower fan by wind-collecting cover respectively, the center of circle of adjacent two heat exchanger tubes of described same horizontally-arranged is isosceles triangle with the vertical center of circle of a corresponding heat exchanger tube, and the span of tube pitch and the ratio of the tube pitch of vertical corresponding heat exchanger tube of two heat exchanger tubes that constitutes the same horizontally-arranged of this isoceles triangle shape is 1.6～2.0.
The heat exchange tube diameter of described same horizontally-arranged all equates; The heat exchange tube diameter of different horizontally-arrangeds equates or is unequal.
Vertical range value between the heat exchanger tube of described adjacent two horizontally-arrangeds equates or is unequal.
In technique scheme, hollow cooler for motor of the present utility model comprises the wind cabinet, is located at number row's heat exchanger tube in the wind cabinet and the wind-collecting cover of being located at wind cabinet one end, the center of circle of adjacent two heat exchanger tubes of same horizontally-arranged is isosceles triangle with the vertical center of circle of a corresponding heat exchanger tube, and the span of tube pitch and the ratio of the tube pitch of vertical corresponding heat exchanger tube of two heat exchanger tubes that constitutes the same horizontally-arranged of this isoceles triangle shape is 1.6～2.0.Adopt the cooler of this kind heat exchanger tube arrangement mode when guaranteeing the heat exchange effect, to greatly reduce the outer windage of pipe, reduced the energy consumption of supporting blower fan, improved the heat exchange effect.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.See also Fig. 1～shown in Figure 5, the overall structure form and the prior art of hollow cooler for motor 20 of the present utility model are basic identical, equally also comprise wind cabinet 21, be located at number row's heat exchanger tube 22 in the wind cabinet 21 and wind-collecting cover 23 (see figure 5)s of being located at wind cabinet 21 1 ends, heat exchanger tube 22 1 ends communicate with outside blower fan by wind-collecting cover 23 respectively, and wind cabinet 21 bottoms are installed surface 211, in order to be installed on the motor, and centre and both sides at installed surface 211 all have the heat exchange ventilating opening, communicate with the air outlet 1 and the air inlet 2 of motor respectively.Different is, the center of circle of adjacent two heat exchanger tubes 22 of the same horizontally-arranged of this cooler 20 is isosceles triangle with the center of circle of a vertical corresponding heat exchanger tube 22, and the span of tube pitch S1 and the ratio of the tube pitch S2 of vertical corresponding heat exchanger tube 22 of two heat exchanger tubes 22 that constitutes the same horizontally-arranged of this isoceles triangle shape is 1.6～2.0, promptly between the pipe of adjacent two heat exchanger tubes 22 of identical horizontally-arranged between the pipe of circulation area and vertical corresponding heat exchanger tube 22 span of the ratio of circulation area be 1.6～2.0.As an embodiment, heat exchanger tube 22 calibers of the same horizontally-arranged of this cooler 20 all equate; And heat exchanger tube 22 calibers of different horizontally-arrangeds can equate, also can be unequal.In addition, the vertical range value between the heat exchanger tube 22 of adjacent two horizontally-arrangeds can equate, also can be unequal.Need to prove at this, the heat exchanger tube of traditional triangular arranged mode, the value of its S1/S2 is 1, is not best arrangement mode.And arrangement mode of the present utility model is to cross according to Chinese scholar to increase the field synergistic principle that first academician proposes, the flow field of heat exchanging device is carried out uniformity and is handled, also promptly pipe is outer adopts uniform flow to flow to calculate, be embodied in: if consider that the density of pipe outer air is constant substantially, uniform flow flows also just to be equal to and waits actual internal area mobile, be the S2 that S1 equals 2 times, but consider that gas stream is not fully perpendicular to the S2 cross section when crossing the S2 cross section, therefore certain streaming arranged, and the value outline of general S2 is less than half of S1.Passed through the mathematical simulation of various working, and the heat exchange property by Shanghai University of Science and Technology is surveyed the repeatedly repetition test of establishing platform, the optimum valuing range that has finally drawn S1/S2 is 1.6～2.0, by this arrangement mode arrange heat exchanger tube 22 cooler 20 the heat exchange effect and the pipe outer windage reached the best.
Please in conjunction with shown in Figure 5, the operation principle of this cooler 20 is as follows:
This cooler 20 is installed on the motor by installed surface 211, and by blower fan and in wind-collecting cover 23 enters wind cabinet 21, and (promptly outer wind path a) for heat exchanger tube 22 is provided for the cold fluid of heat exchange; And the hot fluid that sends of motor (wind path b promptly) enters in the wind cabinet 21 from air outlet 1, and carry out exchange heat with cold fluid in the heat exchanger tube 22, outer wind path a raises the back from heat exchanger tube 22 opposite sides outflow wind cabinet 21 in temperature, interior wind path b then passes through the guide functions of the baffler 212 in the wind cabinet 21 after cooling, flow out from installed surface 211 both sides, and enter in the motor through the air inlet 2 of motor, in order to cooling to the motor feels hot element, and enter cooler 20 through air outlet 1 and carry out heat exchange, by so periodic duty, thereby realization is to effective cooling of motor.
In sum, hollow cooler for motor 20 of the present utility model, simple in structure, the characteristics that bearing capacity is strong and easy to process that have not only kept conventional cooler, and when guaranteeing the heat exchange effect, greatly reduce the outer windage of pipe, reduce the energy consumption of supporting blower fan, improved the heat exchange effect.In general, cooler 20 of the present utility model is under same heat exchange power condition, and the cooler of maximum comparable traditional triangular arranged modes is energy-conservation 25%, therefore has bright development prospect.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
