Further, the flexible plastic pipe sleeve is connected on two outside of vertical portion and its underpart is stuck in groove.
Further, the water inlet pipe connects the water circulating pump of power adaptation with outlet pipe.To ensure the process in test
In there is sufficient water source to absorb the heat distributed.
What the utility model obtained using the above structure has the beneficial effect that：(1) design of cooling sump solves test
When formed air tank influence measured piece heat dissipation the problem of；(2) the design is changing of being carried out on the basis of existing test fixture
Into, it is simple in structure, it is easily fabricated；(3) design of flexible plastic pipe makes measured piece bottom be come into full contact with cooling water, ensures heat
Amount is exported using recirculated water, influences testing precision；(4) water circulating pump is set in system, in the case where ensureing to have abundant water resources
Recycle cooling water solves water resource, reduces testing cost；(5) pollution-free to measured piece in test process, it only needs to be tested
Part is dried；(6) transmission for not influencing microwave signal, may be used on as needed in higher frequency；(7) it can be applicable to not
With on the microwave power amplifier of size, rename particularly with small, high-power microwave power amplifier application effect bright
It is aobvious.
