Description

A kind of heat dissipation CT machine certainly

Technical field

The utility model relates to medical instruments fields, more particularly to a kind of heat dissipation CT machine certainly.

Background technique

During the scanning process, bulb can also generate a large amount of thermal energy, thermal energy warp to CT equipment other than generating X-ray when exposing The radiator for crossing bulb comes out, so that the temperature of detector steeply rises, and high temperature influences the stability of detector data, Causing final imaging quality to decline and generate artifact, and in CT equipment, other electric components can equally generate heat, such as High pressure generator, pcb board etc..In the prior art, in order to which these heats are discharged outside CT equipment, keep equipment internal temperature steady It is fixed, radiator fan is usually added on outer cover, is discharged the heat inside CT equipment by the rotation of fan blade, and suck Cold air cools down to CT equipment, but some shortcomings existing for such radiating mode: need multiple fans to work at the same time when heat dissipation, The operating of fan can generate biggish noise, puzzlement be caused to the use of medical worker and patient, simultaneously because number of fans It is more, installation difficulty, equipment cost and energy consumption are increased, causes inconvenience to manufacturer and user.

Utility model content

To solve the above problems, the utility model provides, one kind is noiseless, radiate CT machine certainly.

To achieve the goals above, the technical solution of the utility model is as follows:

It is a kind of that rotor being installed from heat dissipation CT machine, including stator, stator, front shroud and back cover are stamped on stator, on rotor Equipped with several pieces of blades circumferentially distributed along rotor, the centrifugal air duct opposite with blade is offered in the inner circumferential of stator, stator Outer wall is equipped with the air-out passage communicated with centrifugal air duct, and the area of section of centrifugal air duct gradually expands clockwise along stator inner circumferential Greatly, centrifugal air duct and the area of section of air-out passage junction are maximum, offer several air inlets on back cover.

Further, several described air inlets are circumferentially uniformly distributed along rotor.

Further, strainer is housed on the air inlet.

Further, the air-out passage is located at right above stator.

The utility model has the advantage of the high speed rotations of rotor, so that the blade on rotor drives hot-air rotation, rotation The hot-air turned is discharged through centrifugal air duct from air-out passage under the influence of centrifugal force, simultaneously because the gas of bore of stator is arranged Out, so that the pressure reduction of air inlet, cool exterior air is sucked into bore of stator body from air inlet, to make stator and rotor Temperature reduce, heat dissipation is realized, due to by the rotation of rotor from heat dissipation, making an uproar reducing equipment without installing radiator fan The energy consumption that equipment can also be reduced while sound improves the cost performance and user experience of equipment.

Label declaration

Stator 1, rotor 2, front shroud 3, back cover 4, blade 5, centrifugal air duct 6, air-out passage 7, air inlet 8, bulb 9, high pressure Generator 10, detector 11.

Specific embodiment

The utility model is described in further detail with reference to embodiments.

The present embodiment proposes a kind of from heat dissipation CT machine, as shown in Figures 1 to 4, including stator 1, is equipped with rotor 2 in stator 1, Front shroud 3 and back cover 4 are stamped on stator 1, equipped with bulb 9, high pressure generator 10 and detector 11, the periphery of rotor 2 on rotor 2 On be evenly distributed with six pieces of blades 5, the centrifugal air duct 6 opposite with blade 5 is offered in the inner circumferential of stator 1, on the outer wall of stator 1 Equipped with the air-out passage 7 communicated with centrifugal air duct 6, the area of section of centrifugal air duct 6 gradually expands clockwise along 1 inner circumferential of stator, Centrifugal air duct 6 and the area of section of 7 junction of air-out passage are maximum, since rotor 2 rotates clockwise, closer to air-out passage 7 Locate, the hot-air in centrifugal air duct 6 accumulates more, by incrementally increasing the area of section of centrifugal air duct 6, so that hot-air It can be accumulated in centrifugal air duct 6 without overflowing, offer 12 air inlets, 8,12 air inlets 8 along rotor 2 on back cover 4 Circumferentially it is uniformly distributed.

To prevent the bulky grain dust in air from entering in 1 cavity of stator, the normal operation of CT equipment, the present embodiment are influenced Strainer is removably installed on air inlet 8, strainer can effectively stop the dust in air to enter in 1 cavity of stator, so that CT equipment being capable of prolonged normal effects.

The air-out passage 7 of the present embodiment is located at the surface of stator 1, and the setting of air-out passage 7 and the surface of stator 1 are subtracted Influence of the hot-air of small discharge to medical worker and patient, improves equipment comforts of use.

The working principle of the present embodiment is as described below: when CT equipment is scanned, rotor 2 is clockwise relative to stator 1 High speed rotation, the hot-air that bulb 9, high pressure generator 10 and pcb board on rotor 2 generate under the drive of blade 5 clockwise High speed rotation installs the environment that front shroud 3 and back cover 4 on the stator 1 makes the cavity in stator 1 form a relative closure, High-speed rotating hot-air can only enter centrifugal air duct 6 under the influence of centrifugal force, and along centrifugal air duct 6 from 7 row of air-out passage Out, due to the discharge of the intracorporal hot-air of 1 chamber of stator, so that the pressure reduction of air inlet 8, cool exterior air is inhaled into stator 1 Cavity in, cool exterior air entrance reduce CT equipment temperature.12 air inlets 8 are circumferentially uniformly distributed along rotor 2, are had It is timely entered in 1 cavity of stator conducive to outside air, accelerates the heat dissipation of CT equipment.
