Along with high-power to digital TV transmitter, high power density, the requirement of high compactness, the heat dissipation capacity of the power amplifier unit of transmitter increases substantially.In order to reduce power amplifier unit and to synthesize the working temperature of distribution network electronic building brick and keep it effectively to move, must carry out cooling heat dissipation to prolong the useful life of power component to it, reduce the use noise of transmitter, increase the power density of transmitter under the same volume, simultaneously energy savings.Because it is constantly perfect that the formulation of digital television standard and digital TV transmitter manufacture and design, to the type of cooling of transmitter also by traditional air-cooled liquid cooling that turned to.In the prior art, the method for liquid cooling mode normally that HVAC is commonly used is applied directly on the television transmitter, and there is certain defective in this traditional water-cooling system, as:
1. water consumption is larger: common stainless steel water tank is adopted in water storage, because therefore the water evaporation needs continuous fluid infusion;
2. whole system is owing to adopting open system, and the equipment landing area is larger;
3. internal system liquid touches air, thereby makes the whole system corrosion resistance not strong;
4. traditional common pipe joint style very easily causes leakage, thereby damages electronic device.
Summary of the invention
The defective that exists in order to overcome above-mentioned prior art the purpose of this invention is to provide a kind of liquid cooling system that is applicable to digital TV transmitter.It can realize good digital TV transmitter cooling effect, has the advantages that floor space is little, water consumption is few, corrosion resistance is strong, safe and reliable.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of liquid cooling system that is applicable to digital TV transmitter, its design feature be, it forms by pump unit, heat exchanger unit with to the PLC control cabinet that whole liquid cooling system carries out electrical control.Described pump unit comprises two circulating pumps, two electronic thermometers, electric contact thermometer, expansion drum, electronic pressure transmitter and an electro connecting pressure gauge.Described heat exchanger unit comprises heat exchanger and two blower fans to heat exchanger blowing heat radiation.The outlet of heat exchanger is connected to the entrance of digital TV transmitter circulating line successively through circulating pump two and circulating pump one, wherein circulating pump one is connected on the pipeline between the digital TV transmitter circulating line entrance and is provided with successively automatic decompression valve and electronic thermometer two, is provided with successively electronic pressure gage and electro connecting pressure gauge on the pipeline between heat exchanger and the circulating pump two.The outlet of digital TV transmitter circulating line is connected to the import of heat exchanger, and the pipeline between digital TV transmitter and the heat exchanger is provided with electronic thermometer one.The port of export of the port of export of circulating pump two and circulating pump one links to each other and is connected respectively to the port of export of expansion drum and heat exchanger, and the port of export that circulating pump two and circulating pump one link to each other and the pipeline between the heat exchanger are provided with electric contact thermometer.
In liquid cooling system described above, be equipped with touch-screen on the described PLC control cabinet.
The present invention adopts said structure to solve the problems such as high-power, the high heat density of digital TV transmitter, high use noise, the liquid cooling system that forms has remedied many defectives and deficiency that the air blast cooling cooling technology causes, and have that noise is low, good cooling results, easy care, temperature range characteristics such as comparatively constant comparatively speaking, floor space is little simultaneously, water consumption is few, corrosion resistance is strong, safe and reliable.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, liquid cooling system of the present invention forms by pump unit, heat exchanger unit with to the PLC control cabinet that is equipped with touch-screen that whole liquid cooling system carries out electrical control.The pump unit comprises two circulating pumps, two electronic thermometers, electric contact thermometer, expansion drum 3, electronic pressure transmitter 5 and an electro connecting pressure gauge 6.Heat exchanger unit comprises heat exchanger 7 and two blower fans to heat exchanger 7 blowing heat radiations.The outlet of heat exchanger 7 is connected to the entrance of digital TV transmitter 8 circulating lines successively through circulating pump 2 1.2 and circulating pump 1, wherein circulating pump 1 is connected on the pipeline between the digital TV transmitter 8 circulating line entrances and is provided with successively automatic decompression valve 9 and electronic thermometer 2 2.2, is provided with successively electronic pressure gage 5 and electro connecting pressure gauge 6 on the pipeline between heat exchanger 7 and the circulating pump 2 1.2.The outlet of digital TV transmitter 8 circulating lines is connected to the import of heat exchanger 7, and the pipeline between digital TV transmitter 8 and the heat exchanger 7 is provided with electronic thermometer 1.The port of export of the port of export of circulating pump 2 1.2 and circulating pump 1 links to each other and is connected respectively to the port of export of expansion drum 3 and heat exchanger 7, and the port of export that circulating pump 2 1.2 and circulating pump 1 link to each other and the pipeline between the heat exchanger 7 are provided with electric contact thermometer 4.
The present invention is a closed-cycle system, during work, cooling fluid exports to enter the cooling trunk line of digital TV transmitter 8 inside from the pump unit, this trunk line connects the heat generating components-power amplifier unit of digital TV transmitter 8 by snap joint, then cooling fluid is carried out the water outlet trunk line that thermal convection is taken away heat and flowed into digital TV transmitter 8 by power amplifier unit.Enter the heat exchanger unit of liquid cooling system from the higher cooling fluid of temperature of water outlet trunk line outflow; Heat exchanger unit by being added with fin heat exchanger 7 and by the heat loss through convection effect of two Fans, coolant temperature can descend, near ambient temperature.Lower temperature cooling fluid inflow pump unit entrance from heat exchanger unit flows out flows into digital TV transmitter 8 from the outlet of pump unit again under the controlled circulation effect of pump unit, form closed-cycle system.Wherein the effect of expansion drum 3 mainly is the pressure balance that keeps whole system; The system pressure that the PLC control cabinet can detect in conjunction with electronic pressure transmitter 5 and two electronic thermometers according to the program finished writing in advance and temperature automatically two circulating pumps of control and two Fans startup and stop, thereby can also be effectively energy-conservation when guaranteeing high efficiency and heat radiation.
