Description
Technical field
The present invention relates to laboratory equipment, and in particular to microwave low-noise amplifier.
Background technology
Microwave low-noise amplifier is a kind of very low amplifier of noise coefficient, is typically used as all kinds of radio receivers
High frequency or intermediate-frequency preamplifier, and the amplifying circuit of high sensitivity electron detection equipment.Many Scientific Research in University Laboratory exist at present
Using microwave low-noise amplifier, and caloric value is larger in use for this equipment, and the experimental bench in laboratory does not have
For specially placing the standing groove of the equipment, this equipment is typically fixed on experimental bench by laboratory technician using adhesive tape, reuses USB
Fan carries out wind-cooling heat dissipating against this equipment；Current fixing means are simultaneously unstable and cull can be left in equipment, current
Heat dissipation is also not sufficiently stable easy-to-use.
The content of the invention
Present invention aims at solving the above problems, the invention provides microwave low-noise amplifier, and it should in laboratory
Used time can be such that the present invention is securely placed on experimental bench, and have certain anticollision ability, and the present invention is also integrated with scattered
Hot-air fan, improve radiating efficiency.
The purpose of the present invention is achieved through the following technical solutions：
Microwave low-noise amplifier, including body and base, the base be upper surface open cuboid thin-walled box, institute
To state body and be located at chassis interior, the side wall of the base offers multiple heat emission holes, and fan is respectively arranged with each heat emission hole,
Spring is fixed with the fan, copper coin is fixed with the other end of the spring, the spring and copper coin are respectively positioned in base
Portion, the copper coin are withstood on body surface, and the base bottom is provided with lead.
The body is microwave low-noise amplifier, in the use of the present invention, body is wrapped in interior, base bottom by base
There is lead, therefore base can be securely placed on experimental bench；Pass through because fan and base interfix, therefore with fan
The copper coin of spring connection withstands body can play fixed effect to body；Secondly because spring is flexible, when base by
To when hitting, spring can provide certain cushioning effect, prevent body from being crossed strong impact and damaged.Heat caused by body
Can be conducted by copper coin and spring to fan, fan can discharge base by heat, can be with higher efficiency with reference to solid thermal conduction
Radiated on ground；The present invention includes more set fans, spring, copper coin, therefore can realize the radiating of higher efficiency.
Further, the body is provided with body screw, and the base bottom is provided with base screw, the body screw
It is identical with base screw hole dimensions bore and mutually coincided in vertical direction.In laboratory when needing to fix body, it can pass through
Body screw fixes body with base screw.
Further, the spring uses copper spring, the good heat dissipation effect of copper spring, can lift the radiating of the present invention
Ability.
By using the present invention, following beneficial effect can be produced：The present invention includes body and base, is opened on base side wall
Provided with multiple heat emission holes, fan is housed in each heat emission hole, spring is fixed with fan, copper is fixed with the other end of spring
Plate, copper coin are withstood on the surface of body, and the heat of body can be shed by copper coin, spring, fan, with reference to solid thermal conduction
Can improving heat radiation efficiency, and spring and copper coin can play cushioning effect to body.
