Description
Technical field
It the utility model is related to laboratory equipment, and in particular to a kind of 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 placing groove of the equipment, this equipment is generally 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 residue glue can be left in equipment, current
Heat dissipation is also not sufficiently stable easy-to-use.
Utility model content
The utility model aim is to solve the above problems, and the utility model provides a kind of microwave low-noise amplifier,
It can be such that the utility model is securely placed on experimental bench in laboratory applications, and have certain anticollision ability,
The utility model is also integrated with radiator fan, improves radiating efficiency.
The purpose of this utility model is achieved through the following technical solutions：
A kind of microwave low-noise amplifier, including body and base, the base are the cuboid thin-walled of upper surface open
Case, the body are located at chassis interior, and the side wall of the base offers multiple heat emission holes, are respectively arranged with each heat emission hole
Fan, is fixed with spring on the fan, copper coin is fixed with the other end of the spring, the spring and copper coin are respectively positioned on bottom
Seat is internal, and the copper coin is withstood on body surface, and the base bottom is equipped with lead.
The body is microwave low-noise amplifier, when the utility model is used, body is wrapped in interior, base by base
Lead is arranged at bottom, therefore base can be securely placed on experimental bench；Since fan and base interfix, with fan
The copper coin connected by spring, which withstands body, can play body fixed effect；Secondly because spring has elasticity, work as bottom
When seat is hit, spring can provide certain cushioning effect, prevent body from being crossed strong impact and damaged.Caused by body
Heat, which can be conducted by copper coin and spring to fan, fan, to discharge base by heat, can be with higher with reference to solid thermal conduction
Efficient radiate；The utility model includes more set fans, spring, copper coin, therefore can realize the heat dissipation of higher efficiency.
Further, the body is equipped with body screw hole, and the base bottom is equipped with base screw hole, the body screw hole
It is identical with base screw hole dimensions bore and mutually coincide in vertical direction.In laboratory when needing fixed body, it can pass through
Body screw hole fixes body with base screw hole.
Further, the spring uses copper spring, and the good heat dissipation effect of copper spring, can lift the utility model
Heat-sinking capability.
By using the utility model, following beneficial effect can be produced：The utility model includes body and base, base
Multiple heat emission holes are offered on side wall, fan is housed in each heat emission hole, spring is fixed with fan, is consolidated on the other end of spring
Surely there is copper coin, copper coin is withstood on the surface of body, and the heat of body can be shed by copper coin, spring, fan, with reference to solid
Heat transfer can improving heat radiation efficiency, and spring and copper coin can play cushioning effect to body.
