The outer surface of the shell of the load body is fully utilized as the bottom surface of the water channel, the cover plate is welded on the shell, the water channel is formed in the middle, and the water inlet end and the water outlet end of the water channel are designed at the front heating concentration part of the shell, so that the heat of a product can be better taken away; the problem that the air-cooled structure heat dissipation can not meet the heat dissipation requirement of the high-power waveguide dummy load is solved by adopting the water-cooled structure heat dissipation.
Description
Technical Field
The utility model relates to a radar equipment technical field, especially a high-power waveguide dummy load.
Background
Most of traditional similar waveguide dummy load products are air-cooled structures with radiating fins, the average power borne by the products is usually lower than one kilowatt, and for the products which are required to bear the average power more than one kilowatt, the heat dissipation requirements cannot be met by continuously adopting the air-cooled structures for heat dissipation.
SUMMERY OF THE UTILITY MODEL
For solving the problem that exists among the prior art, the utility model provides a high-power waveguide dummy load.
The utility model adopts the technical proposal that:
the utility model provides a high-power waveguide dummy load, includes the load body, the welding has the apron on the shell of load body, form the water course between the shell of apron and load body, and the end of intaking and the play water outlet end of this water course are located the both sides that the shell front end was generated heat and is concentrated the department respectively, the end of intaking and the play water outlet end of water course are connected with the water injection well choke respectively, the one end that the water injection well choke is close to the water course is equipped with the ring flange, the water injection well choke passes through the ring flange and is connected with the water course, and.
Preferably, the water nozzle is made of austenitic stainless steel.
Preferably, the flange plate is connected with the water channel through screws.
The utility model has the advantages that: the outer surface of the shell of the load body is fully utilized as the bottom surface of the water channel, the cover plate is welded on the shell, the water channel is formed in the middle, and the water inlet end and the water outlet end of the water channel are designed at the front heating concentration part of the shell, so that the heat of a product can be better taken away; the problem that the air-cooled structure heat dissipation can not meet the heat dissipation requirement of the high-power waveguide dummy load is solved by adopting the water-cooled structure heat dissipation.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
The utility model provides a high-power waveguide dummy load, includes the load body, the welding has the apron on the shell of load body, form the water course between the shell of apron and load body, and the end of intaking and the play water outlet end of this water course are located the both sides that the shell front end was generated heat and is concentrated the department respectively, the end of intaking and the play water outlet end of water course are connected with the water injection well choke respectively, the one end that the water injection well choke is close to the water course is equipped with the ring flange, the water injection well choke passes through the ring flange and is connected with the water course, and.
In one embodiment, the water nozzle is made of austenitic stainless steel.
In one embodiment, the flange plate is connected with the water channel through screws.
The adoption of the water-cooled structure involves three problems which must be solved: firstly, the structure and the trend of a water channel; how to connect the water channels of the input end and the output end and what material is adopted; and thirdly, the pressure born by the water channel and the water nozzle (the pressure is required to be more than or equal to 0.3MPa and no water leakage is caused).
Because waveguide dummy load generates heat and mainly concentrates on the front end, consequently will take away this heat, satisfies the heat dissipation function of product, the utility model discloses the surface of make full use of load shell welds the apron as the bottom surface of water course on the shell, and the centre has just formed a water course, and the end of intaking of water course and the end of water outlet just design the front end of shell and generate heat concentrated department, just so can take away the heat of product better.
Because the waveguide dummy load shell is made of aluminum-silicon alloy, and the welding process is considered, the water channel and the water nozzle are made of the same-grade aluminum-silicon alloy, and the water channel and the water nozzle are welded by argon arc welding. But require the water injection well choke material to be austenitic stainless steel under the partial condition, this just brings a technological problem, and stainless steel and aluminium silicon alloy welding process are poor, consequently the utility model discloses design into a water injection well choke of taking the ring flange with the water injection well choke, adopt screw and apron to be connected, the centre is sealed with the rubber pad, has just solved the connection problem of water injection well choke.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
