Detailed Description

Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the utility model, and are not intended to limit the scope of the utility model.

As shown in fig. 1, the main chassis of the ultrasonic device provided by the utility model comprises a chassis 100 and an induced air component 200, wherein at least one air duct 110 is formed in the chassis 100, two ends of the air duct 110 are communicated with the outside, the air duct 110 is provided with a plurality of mounting positions, loads are mounted at the plurality of mounting positions along the extending direction of the air duct 110, and the air duct 110 is provided with a plurality of corners so as to isolate electromagnetic interference between the loads mounted at two sides of the corners; the induced draft assembly 200 is disposed in the chassis 100 and is in communication with the air duct 110, so as to form a heat dissipation airflow in the air duct 110 along the extending direction of the air duct 110.

In this embodiment, the chassis 100 is a rack structure of an ultrasonic device, at least one air duct 110 is formed in the chassis 100, two ends of the air duct 110 are communicated with the outside, the air duct 110 has a plurality of mounting positions, and loads are mounted along the extending direction of the air duct 110, instead of the traditional centralized layout mode, a plurality of loads in the chassis 100 are dispersed, the heat flow density and electromagnetic density in the chassis 100 are reduced, the air duct 110 has a plurality of corners to isolate electromagnetic interference between loads mounted on two sides of the corners, and meanwhile, the air induction assembly 200 is built in the chassis 110 and is communicated with the air duct 110 to form a heat dissipation airflow flowing along the extending direction of the air duct 110 in the air duct 110 so as to guide out heat in the air duct 110.

The chassis 100 in this embodiment is a rack structure of an ultrasonic equipment host, and is used for protecting the load inside the chassis, so as to solve the problem that the heat is seriously concentrated, the heat dissipation effect is poor and the electromagnetic environment is complex because the loads inside the existing host are all in a centralized layout manner, and the structure of the chassis 100 is improved. Specifically, at least one air duct 110 is formed inside the chassis 100, two ends of the air duct 110 are communicated with the outside, the air duct 110 has a plurality of mounting positions, and the plurality of mounting positions mount loads along an extending direction of the air duct 110. Instead of the conventional centralized layout, multiple loads in the chassis 100 are dispersed, the heat flux density and electromagnetic density in the chassis 100 are reduced, and the air duct 110 has a plurality of corners to isolate electromagnetic interference between loads mounted on both sides of the corners.

It should be noted that, the "load" described above is each electronic device inside the ultrasound host, such as a board card, a power supply, etc., and is a structure that can be considered by those skilled in the art, and will not be described herein.

In some embodiments, the manufacturing process of the chassis 100 is not limited, and for example, a plurality of plates may be spliced and formed, or may be formed in an integral manner, so long as a structure having the air duct 110 therein can be formed. Meanwhile, it should be noted that the case 100 should have a detachable portion for installation and maintenance, for example, a detachable side plate is provided on a side wall of the case 100, and the air duct 110 is exposed after the side plate is detached, and the detachable manner is not limited, for example, screw connection, snap connection, etc.

In some embodiments, the shape of the air duct 110 within the chassis 100 is not limited, wherein the shape of the air duct 110 is related to its length, width, and direction of extension, as described below.

Firstly, the shape of the air duct 110 is related to the length thereof, the longer the length of the air duct 110 is, the better the dispersing effect among a plurality of loads is, the more the loads can be installed, if the number of the loads to be installed is fixed, the larger the distance between two adjacent loads along the extending direction of the air duct 110 is, the heat flow density and electromagnetic density in the case 100 can be effectively reduced, of course, the length of the air duct 110 is limited by the volume of the case 100, and the adaptive length should be selected according to the volume of the case 100.

Second, the shape of the air duct 110 is related to its width, and the width of the air duct 110 in the cabinet 100 should satisfy the space required for load installation, for example, the width of the air duct 110 along its extension direction may be equal everywhere, and at this time, the width of the air duct 110 should be greater than the installation space required for the load with the largest volume; for another example, the width of the air duct 110 along the extending direction may also be set in a variable diameter manner, where "variable diameter" refers to that the size of the cross section of the air duct 110 along the extending direction of the air duct 110 may be adaptively changed, that is, the sizes of the cross sections at different positions in the air duct 110 may be different, so that the installation space required by the loads with different volume sizes is matched with the size of the cross section of the corresponding installation position of the air duct 110, and the width of the air duct 110 should be determined according to the setting position of the air duct 110 in the chassis 100.

Finally, the shape of the air duct 110 is related to the extending direction, the air duct 110 extends in different directions in the chassis 100, and air ducts 110 with different shapes can be formed, and it is understood that in a case that the volume of the chassis 100 is fixed, the air duct 110 should be extended along the length and/or width direction of the chassis 100, and the internal space of the chassis 100 is occupied to the greatest extent to increase the length of the air duct 110.

Although the shape of the air duct 110 is not limited, the air duct 110 should be formed so as to avoid excessive corners and take a linear shape as much as possible. Specifically, the number of straight or quasi-straight (e.g., arc-shaped) corners is small, and the loss of the air flow in the air duct 110 during the flowing process is small, so as to ensure that the air flow in the air duct 110 effectively brings heat out.

The arrangement of the load and the size of the equipment also need to be considered in designing the air duct. Specifically, from the arrangement of internal loads, under the condition that the equipment volume is certain, the more the loads are, the more crowded the loads are, the worse the heat dissipation effect is, otherwise, the fewer the loads are, the larger the distance between the loads is, and the better the heat dissipation effect is; in terms of the size of the equipment, under the condition that the number of the loads is fixed, the smaller the size of the equipment is, the more crowded the loads are, the worse the heat dissipation effect is, and on the contrary, the larger the size of the equipment is, the larger the distance between the loads is, and the better the heat dissipation effect is. Therefore, the design of the heat dissipation air duct is comprehensively determined by the arrangement of the comprehensive heat source components and the size of the equipment volume, and in the ultrasonic equipment, firstly, the number of loads is fixed, the loads cannot be reduced at will, otherwise, the operation and the use of the ultrasonic equipment cannot be supported, secondly, most medical ultrasonic equipment needs to move back and forth, the smaller and lighter the whole equipment is, the easier the whole equipment moves, based on the two points, how to reasonably layout the loads in a space as small as possible, meet the heat dissipation requirements among the loads, avoid electromagnetic interference, and are critical problems to be solved in the ultrasonic equipment.

Through the zigzag air duct 110, the inner space of the chassis 100 can be occupied to the greatest extent, the length of the air duct 110 is long, the heat flow density and electromagnetic density in the chassis 100 can be reduced to the greatest extent, the zigzag air duct 110 has only two corners, the corners are fewer, the wind energy loss in the air duct 110 is fewer, meanwhile, the air inlet 120 and the air outlet 130 are horizontally arranged along the air inlet and outlet direction, the air inlet and outlet are not blocked, and the air flow in the air duct 110 is smooth.

In a specific implementation process, the plurality of loads include the high-voltage component 400 and the functional component 500, wherein the high-voltage component 400 has higher heat during operation, the functional component 500 has lower heat during operation, the high-voltage component 400 can be installed in the first connection section, the functional component 500 is installed in the first connection section, and the plurality of loads realize gradient temperature arrangement along the flow direction of the heat dissipation airflow in the air duct 110, so that the heat dissipation effect is better.

In other embodiments, the air duct 110 may also have a C-shape, a wave shape, etc., which is not limited in the embodiments of the present utility model, and is mainly aimed at sequentially arranging a plurality of loads along the extending direction of the air duct 110, so as to avoid heat concentration and complex electromagnetic environment inside the chassis 100 caused by stacking the plurality of loads.
