Abstract
The utility model is applicable to the field of LED display screen temperature control and discloses an LED display screen temperature control system, which comprises a first heat exchanger arranged in an LED display screen box body, a second heat exchanger deeply buried underground and a thermal insulation pipe which is connected with the first and second heat exchangers and forms a circulating pipeline, wherein the thermal insulation pipe is filled with a circulating working medium and is provided with a circulating pump used for providing power to the working medium in the thermal insulation pipe. In the system, the buried thermal insulation pipe is adopted and, under the drive of the circulating pump, the working medium in the thermal insulation pipe flows circularly to collect heat from the soil and supply the heat to an LED screen body, or to collect cold energy from the soil and release the excessive heat generated in the operation of the LED screen body to ground energy. The system is free from influences of environment, energy-saving, environmentally-friendly, long in service life and low in maintenance cost.
Description
Technical field
The utility model relates to LED display temperature control field, relates in particular to a kind of LED display geothermal temperature control system.
Background technology
Existing LED display temperature control has dual mode usually, and a kind of is to adopt open-air cooling water circulation, promptly by recirculated water the heat of LED display screen body inside is taken to the form of outside cyclic water tank and normal temperature air generation heat exchange.Shortcoming is: the cyclic water tank under exposure and the normal temperature is subjected to the natural environment Temperature Influence easily, thereby causes the cooling inefficiency, and the water of adding cyclic water tank constantly evaporates, and causes later maintenance to need regularly to add recirculated water.
Another kind is to adopt the conventional air-conditioning cooling, promptly installs an air-conditioner at the LED display box house, compressor is positioned over the form of casing outside.Shortcoming is: compressor displacement is subject to the influence of sand and dust and produces mechanical breakdown; The destruction that the cold-producing medium of air-conditioning unit when work volatilization is serious the ozone layer of the earth; The energy consumption of air-conditioning unit is bigger, and the later maintenance expense is too high.
The utility model content
Technical problem to be solved of the present utility model is to propose a kind of LED display temperature control system.It is not affected by environment, energy-conserving and environment-protective, and long service life, maintenance cost is low.
For addressing the above problem, the utility model proposes the LED display temperature control system, comprise the insulating tube that is installed on the first interior heat exchanger of LED display casing, buried second heat exchanger, connection first heat exchanger and second heat exchanger and forms circulating line, be filled with cycle fluid in the insulating tube and the circulating pump that is used for providing power to the insulation intraductal working medium is installed in below ground.
Described first heat exchanger is tubular type or slice structure.
Described second heat exchanger is buried in underground 4-5 rice depths.
Described second heat exchanger is tubular type or slice structure.
Described insulating tube is that pvc material is made.
Described insulating tube inside is filled with aqueous water or chemical coolant.

Embodiment
Core concept of the present utility model is, but utilize the not only heat supply of geothermal using resource but can freeze, annual ground temperature fluctuation little (soil remains on 15-17 degree centigrade throughout the year), characteristic cool in summer and warm in winter, adopt buried insulating tube, by circulating of intraductal working medium, from soil, gather heat and supply with LED screen body; Or from soil, gather cold, LED is shielded heat release unnecessary in the running body in the ground energy.
As shown in Figure 1, the utility model geothermal temperature control system comprises: heat exchanger 01, heat exchanger 02, connect heat exchanger 01 and heat exchanger 02 and form circulating line insulating tube 03, be installed in the circulating pump 04 on the insulating tube.
Wherein, described heat exchanger 01 is a plate heat exchanger, is installed on the above LED display box house in ground, and the mode by forced heat radiation (as adding fan) or heat loss through convection of being used for is carry the cold that comes up or heat release to the screen body through circulating pump 04; Described heat exchanger 02 is buried to be tubular type or plate heat exchanger in underground 4-5 rice depths, is used for by the mode of natural heat dissipation the heat or the cold that bring through the working medium of over-heat-exchanger 01 being discharged into soil.Described insulating tube 03 be polyvinyl chloride (Polyvinylchloride, PVC) or other materials make, be connected between heat exchanger 01 and the heat exchanger 02 and form circulating line, its body inside is filled with working medium such as aqueous water or other chemical coolants; Described circulating pump 04 is the AC system circulating pump, is used to the working medium of operation in insulating tube 03 body that forms circulating line that circulation power is provided.
When making refrigeration work summer, the temperature of below ground is 15-17 degree centigrade, lower than the temperature more than the ground, the power that buried working medium in underground insulating tube 03 pipe provides by circulating pump 04 is delivered to cold LED and is shielded in the heat exchanger 01 in the body, the mode of heat exchanger 01 by forced heat radiation (as adding fan) or heat loss through convection is discharged into cold and makes the cooling of LED screen body in the screen body, the high temperature of LED screen body makes the working medium temperature in insulating tube 03 pipe raise simultaneously, under the effect of circulating pump 04, the working medium of elevated temperature flows to buried in underground heat exchanger 02, in soil, the working medium temperature in insulating tube 03 pipe reduces the mode of heat exchanger 02 by natural heat dissipation the heat release of bringing through the working medium of over-heat-exchanger 01.
When heating work in the winter time, the temperature of below ground is 15-17 degree centigrade, than the temperature height more than the ground, the power that buried working medium in underground insulating tube 03 pipe provides by circulating pump 04 is delivered to heat LED and is shielded in the heat exchanger 01 in the body, the mode of heat exchanger 01 by forced heat radiation (as adding fan) or heat loss through convection rejects heat to LED screen body heated up, the low temperature of LED screen body makes the working medium temperature in insulating tube 03 pipe reduce simultaneously, under the effect of circulating pump 04, the working medium that has reduced temperature flows to buried in underground heat exchanger 02, heat exchanger 02 is discharged into the cold that brings through the working medium of over-heat-exchanger 01 in the soil by the mode of natural heat dissipation, and the working medium temperature in insulating tube 03 pipe raises.
The utility model adopts buried insulating tube, drives circulating of insulation intraductal working medium by circulating pump, gathers heat and supply with LED screen body from soil; Or from soil, gather cold, LED is shielded heat release unnecessary in the running body in the ground energy.It is not affected by environment, energy-conserving and environment-protective, and long service life, maintenance cost is low.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
