E-load machine is owing to will simulate various consumers, transistor in the circuit is as the load of control device and the tested power supply of electric current, its thermal value is larger, thereby the radiating subassembly of larger volume need to be set in E-load machine, and transistor is arranged on the radiating subassembly, so that the heat that transistor sends can in time distribute by radiating subassembly.In order to ensure radiating efficiency, radiating subassembly manufactures a rectangular shape, to form relatively straight thermal dissipating path.The radiating subassembly that is illustrated in figure 1 as existing E-load machine arranges synoptic diagram, and radiating subassembly 110 vertically is arranged in the cabinet 100 of E-load machine, and its thermovent 103 is arranged on the rear panel 101 of cabinet.And because the length of radiating subassembly 110 is longer, cause the vertical extension of cabinet 100 longer, both sides at radiating subassembly 110, do not need other assembly of arranging, thereby be unnecessary space in the both sides of radiating subassembly, the waste of the space of cabinet 100 inside is larger like this, has caused the E-load machine volume larger, is inconvenient to place and carry.
The utility model content
Technical problem to be solved in the utility model provide a kind of good heat dispersion performance, small volume E-load machine.
The purpose of this utility model is achieved through the following technical solutions: a kind of E-load machine comprises: cabinet and radiating subassembly, described radiating subassembly is horizontally installed in the cabinet.
Preferably, described radiating subassembly comprises: heat radiator and the heat-dissipating frame that is used for fixing cooling fins, and described heat-dissipating frame is fixed on the described cabinet, and the thermovent of described radiating subassembly is arranged on the side frame of described cabinet.By heat-dissipating frame heat radiator is fixed on the cabinet, thus position and the direction that can reasonably arrange heat radiator, and in addition, through hole is arranged on thermovent on the side frame of cabinet, so that radiating subassembly directly contacts with the cabinet extraneous air, improves radiating efficiency.
Preferably, described heat radiator is separately positioned on the upper and lower side of described heat-dissipating frame.By heat radiator all being set up and down to increase area of dissipation, improve radiating efficiency.
Preferably, the heat radiator on the upper and lower side of described heat-dissipating frame is oppositely arranged.So that heat to distribute approach orderly, thereby improve radiating efficiency.
Preferably, leave the interval between the heat radiator of described upper and lower side.So that the space of a circulation of air is arranged in the radiating subassembly, to improve radiating efficiency.
Preferably, an end of described radiating subassembly is provided with radiator fan.Improve the speed of circulation of air by radiator fan, thereby improve radiating efficiency.
Preferably, described radiator fan is arranged on the thermovent of described radiating subassembly.In time hot-air is discharged toward the guiding of thermovent direction by fan, improve radiating efficiency.
The utility model is owing to be horizontally installed on the radiating subassembly of E-load machine the inside of cabinet, like this, cabinet will be reduced at vertical width, simultaneously, the radiating subassembly of horizontally set takes full advantage of the intermediate space in the cabinet, thereby so that the body of E-load machine can become is less, save cabinet materials'use simultaneously placement and the carrying of more convenient E-load machine.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Be illustrated in figure 2 as E-load machine of the present invention, it comprises: cabinet 100 and be horizontally installed on radiating subassembly (only showing the heat-dissipating frame 110 of radiating subassembly among the figure) in the cabinet 100, the thermovent 103 of radiating subassembly is arranged on the side frame of cabinet 100.Because the thermovent 103 of radiating subassembly in the E-load machine is arranged on the side frame of cabinet, so that radiating subassembly can be horizontally installed on the inside of cabinet 100, like this, cabinet 100 will be reduced at vertical width, simultaneously, convenience for operations such as wiring, the wiring board of E-load machine inside, the elements such as transformer are arranged on the rear panel 101 and front panel 104 of cabinet 100 more, cause the larger waste of central space, and the radiating subassembly of horizontally set takes full advantage of the central space in the cabinet, thereby so that the body of E-load machine can become is less, save cabinet materials'use simultaneously placement and the carrying of more convenient E-load machine.
Radiating subassembly comprises: the heat-dissipating frame of a rectangle and the heat radiator that is arranged on heat-dissipating frame inside.Be illustrated in figure 3 as the layout synoptic diagram of the inner fin of radiating subassembly, heat radiator 111 is separately positioned on the upper and lower side of heat-dissipating frame 110, and the top and the bottom of radiating subassembly all are provided with heat radiator 111 like this, have improved area of dissipation, thereby improves radiating efficiency.
111 one-tenth of the heat radiator of heat-dissipating frame 110 inside are oppositely arranged, and like this, so that the dissipation of heat approach of radiating subassembly inside is orderly, thereby so that the heat radiation approach is shorter, improve radiating efficiency.
Leave the interval between the up and down heat radiator 111 in the radiating subassembly, this has so that can leave the space of a circulation of air in the radiating subassembly, to improve radiating efficiency.Certainly, in the present embodiment, as shown in Figure 3, when the heat radiator 111 of radiating subassembly inside is arranged in radiating subassembly shape leave the clearance space of a cross, to guarantee the circulation of air.
In order to improve the speed of circulation of air, improve radiating efficiency, can also radiator fan be set at an end of radiating subassembly.In the present embodiment, radiator fan is arranged on thermovent 103 places of radiating subassembly, and thermovent 103 namely is arranged on the side frame of cabinet 100, like this can be directly with the Bas Discharged of heat exchange in the radiating subassembly, and then improved the radiating efficiency of radiating subassembly.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
