Description

Mixed refrigerator for computers and circuits electronic

The present invention relates to a mixed refrigerator for computers and electronic circuits that constitutes from three circuits: A main circuit of absorption, a secondary evacuation circuit and a third heat exchanger circuit linking the main circuit and the secondary.

Its application is framed within the industry of refrigerators for electronics and particularly within the computer cooler industry and electronic circuits.

In the state of the art they are known computer refrigerators as well as ventilation systems forced for computer components. It's about systems Composite fans or not attached to a heatsink and this to the component or enclosure to cool. They also know each other liquid cooling systems, in which the components to refrigerate contain blocks through which a liquid flows refrigerant, transmitting the heat produced by the components to the block and this to the liquid, which is cooled by radiators with fans. Extreme cooling systems are also known. for cpu computers, which only cool the cpu of the pc by middle of a block that adheres to it, posing as this block a refrigerant gas that evaporates at -10 ° C.

The disadvantages of these systems known against the proposed invention are the following: forced ventilation systems feature several fans that generate noise and its effectiveness depends on the temperature in the computer case or closet. In cooling systems liquid efficiency depends on the temperature of the enclosure where find the computer, the higher the room temperature Less is its evacuation capacity. Cooling systems Extreme are only able to cool the CPU, not the rest of the components and it is necessary to take precautions to avoid condensation of the thermal contact element, which may cause damage to the system to be cooled by condensation of water in the components, since the metal block that is in contact with the CPU evaporates with a gas at a temperature of -10 ° C.

The present invention solves these inconveniences contributing to the state of the art the following Advantages: Multiple fan noises are eliminated. Efficiency The system does not depend on the temperature of the pc case or wardrobe. It can work at a temperature of 50ºC according to the room temperature in the place where the closet is located. The temperature of the transmitting liquid is maintained between values known, avoiding damage to the components, due to instability in the temperature of the air that evacuates the heat. It is a system capable of apply to multiple components of a computer or closet  with electronic components and not just one component determined.

These pipes are subject to system elements by flanges or any appropriate fastening means.

- Transmitting liquid pump. Element that guarantees that the transmitting liquid circulates with a pressure and constant speed, allowing thermal exchange between the Liquid block and excess heat extraction system. This pump can be submersible inside a tank where stores the coolant and in turn be part of a set called heat exchanger or it can be attached mechanically by means of joints, flanges or fittings to a tank, in in which case the pump is an external part of the circuit hydraulic.

It is made of any material that guarantees the tightness of the refrigeration circuit and not deteriorate with the refrigerant gas or working temperature. May be of variable flow and be wrapped by insulating material of noises In turn it can be helped by any system of ventilation that supports sensible heat removal around of the compressor, either by the action of an exclusive fan or taking advantage of any air flow generated by others fans. There is at least one compressor, or more, depending on the system needs

- Condenser or heat exchanger Fridge. This element guarantees heat removal from the refrigeration compressor. It consists of a tube static copper that passes through sheets embedded in aluminum or any other suitable metal and that when the air circulates by its interior, the heat yields to the surroundings. The system incorporates one or several capacitors coupled in series or in parallel to the system, according to its needs or is attached to the fan of heat extraction by means of anti-vibration joints.

- Cold coolant exchanger. It is similar to the refrigerating condenser, with the differences that This exchanger is designed for the passage of liquid refrigerant and not refrigerant gas, it is also different in size, since it can have different dimensions, thus adapting to the different cooling needs of components. Is a air-to-air cooling system, not by contact, and allows the cooling of a specific component or of a certain enclosure, passing air through it and of there to the component or enclosure, since by this exchanger cooled coolant circulates.

- Coolant level buoy. This element is safety for the coolant level and its function is to communicate the liquid level to the control system existing. It can be of various materials, as long as it is not deteriorate due to the composition or temperature of the liquid refrigerant. There are different types of buoy, being the most usual for these assemblies the miniature float mechanics, those of direct current or low intensity pulses between Two poles or by ultrasound.

- Cable glands or connection elements sealed. These elements allow passage through pipes, probes or cables to a normally closed element and that, by your waterproof property, will keep this as waterproof, using to mechanically seal a certain component. This union of external components to an enclosure Watertight may also be made using hoses that are attached on one side to said enclosure in a sealed manner by the same component manufacturing and on the other hand so mechanical by means of flanges or fittings.

- High and low pressure pressure switches. These elements are responsible for transmitting to the control unit by means of a signal by open or closed contacts, the excess of pressure in the case of high pressure switch or lack of pressure in the case of the low pressure switch of the refrigeration circuit. These elements may be threaded to the refrigeration pipes or soldiers. They can also be digital pressure transducers with outputs proportional to the measured pressures.

- Mixed refrigerator container box. The elements that make up said container may be constituted by the same enclosure, box or cabinet of the pc, as long as the appropriate dimensions are available. This box will be like minimum of painted iron and thick enough to withstand mechanical pressures and stresses of the components, with designs standardized to house the computer components or electronics needed plus the mixed refrigerator. There may be possibility, in existing computer equipment such as, PC boxes, computer cubes or barebones, in which no there is a physical possibility of incorporating the cooling system mixed, so the computer equipment itself will add the coolant blocks needed and separately, in another box external mixed cooling equipment will be mounted with its pump and corresponding heat exchanger, joining both, equipment refrigerator and equipment to be cooled by rigid connections or flexible for the passage of coolant, as long as withstand the pressures and temperatures of work and the environment or means through which said tubes should circulate, thus allowing solve size problems in equipment boxes existing.

In addition to the components already mentioned, the The present invention is composed of: Power supply, motherboard, Vga, 5.25 '' refrigerator block hard drive, ram 1 in refrigerator block (9), ram 2 in refrigerator block (10), no this number of components being limited to those mentioned, but there are many others that are not mentioned and in quantities variables

The following elements are intended to be refrigerated: Power supply through liquid exchanger cold coolant and hard drive, chipset, vga cpu, cpu motherboard, Ram 1 and Ram 2 through refrigerator block.

These blocks are interconnected with each other. by rigid or flexible pipes, as well as to the system of immersion of the liquid part of the submersible pump incorporated in The inside of a waterproof tank. This waterproof tank performs two functions, one of them maintains a liquid remnant refrigerated for recirculation by the system to be cooled and another acts as part of a heat exchanger, thanks to a spiral through which refrigerant gas circulates in a circuit refrigerator and cools the transmitter liquid. This deposit presents several independent elements of the pump and the spiral of cooling that are: Thermal insulation of the tank, watertight gland, liquid temperature probe coolant, manual refill plug, safety buoy minimum level of coolant, rubber damping vibrations and screws with thread and double washer.

The application is controlled by the unit of control, which is responsible for collecting all data from probes and activate the actuators accordingly. Pump coolant drive circuit is always in operation, while the computer is running, and can adjust your speed or not through PWM pulses, depending on the temperature measured by the temperature probe. The liquid coolant driven by the pump passes to the heat exchanger coolant from the power supply and starts to cool down because the control unit maintains a coolant temperature, according to the information in the temperature probe, of 25ºC with a differential of + - 2ºC, being this value variable by the user.

The cold coolant exchanger is located behind the power supply, in which there are air intake openings that, through the action of a fan, sucks air from inside the pc case and does go through the power supply components proceeding to its cooling Air passes through the exchanger from the air openings, cools it and enters the power supply, to the appropriate speed according to the setpoint temperature of the unit of control.

The coolant leaves the exchanger of cold coolant to the next block a refrigerate, which is the motherboard chipset. This block allows transmit heat from the chipset to the liquid block so mechanical and liquid block to the circulating transmitter fluid inside by block-liquid transmission, by what while transmitting liquid is circulating through the block, will pick up the heat of it.

The cpu of the motherboard is cooled by liquid block, the coolant flows out of the chipset towards the motherboard cpu, and the cpu to ram 1 and ram 2 memories, with the peculiarity that the block systems of ram 1 and ram 2 are made of liquid that wrap the rams and the heat of the component is transmitted to the block through transmitter silicone of heat in solid state. This system of action is the same than the rest of the components already described.

From the ram 2 the coolant flows to the hard disk cooler block, whose transmission system is also block-silicone transmission in state solid.

The hard drive is the last component to refrigerate, so that from its exit, the transmitting liquid goes from back to the tank in a cold area where it quickly cools off New and is used again.

The heat exchanger tank incorporates a minimum level liquid transmitter buoy that, controlled by the control unit monitors that, if a minimum level is reached of liquid, will emit an audible alarm. This deposit incorporates a thermal insulator to avoid external heat input and is anchored to the box or container mechanically, using rubber bands Silencers and screws with double washer or other system adequate support. The tank incorporates a filler cap.

The cooling part of the cooling circuit of Transmitting liquid consists of the following elements: Refrigerator compressor, high pressure switch, copper pipe High pressure thermally insulated, heat exchanger refrigeration circuit, heat exchanger fan, probe temperature control, anti-vibration rubber gasket, hardware fan anchor and heat exchanger, rubber anti-vibration compressor anchor, fastening screws Compressor, low pressure switch, control probe anti-icing, anchoring of cold pipes with separator and flanges of rubbers, anchoring of refrigerated pipes to box or closing of rubber, high pressure insulated pipe, low pressure pipe, dehydrator filter of the refrigerant circuit, restrictor, capillary or thermostatic valve, spiral or gas evaporator ring Refrigerator and heat exchanger tank.

The refrigeration circuit is a circuit hermetic, made by mechanical joints with their respective together, which has refrigerant gas inside R-134 A. When the PC starts up, the control unit checks the temperature of the transmitting liquid by means of the probe that when detecting a temperature higher than the programmed, performs a minimum timing of 30 seconds and a Once done, connect the compressor, which begins to compress the gas coming from the low pressure pipeline and coming out of the pipeline high pressure, evacuating the heat it has collected, through the refrigerator condenser and a fan, whose speed is controlled by the control unit using the temperature probe of the fan giving it much more speed the higher The temperature detected. Once the gas has cooled and liquefied having lost temperature in the condenser, it is driven by the high pressure pipe to the dehydrator filter it collects the particles of the refrigerating circuit, viscous material or moisture that could damage the system. From the dehydrator filter it goes to capillary restrictor or thermostatic valve.

The gas passes through the refrigerating spiral and returns down the low pressure line to the compressor returning to Start the refrigeration circuit. The exchanger fan of refrigerating heat is anchored to the box or enclosure jointly and severally by an appropriate union system provided with a vibration insulating rubber. The compressor incorporates some blocks of rubber in its anchorage united in solidarity with the iron. The high and low pressure pipes are attached in solidarity by appropriate binding means provided with anti-vibration gums.

The high pressure and low pressure switch pressure indicate to the control unit the circuit pressure refrigerator to control the fan speed of the Refrigerator exchanger or disconnect the system in necessary case. The frost temperature probe indicates the control unit the return temperature of the heated gas, which if it returns too cold, it will decrease the speed of the pump that in this case it will heat the coolant so that it reaches more heat to the refrigerator exchange spiral, disconnecting the system or issuing an alarm or both, if it were necessary.

The control unit is from a 5.25 '' bay and goes Built-in and anchored by universal fastening screws of these elements and measures or reads the probes or sensors of the system and controls the actuators of all equipment. This unit of control incorporates a connecting cable representing a bus connection for the components, also incorporates an LCD display of 16 x 1 to make changes to instructions and obtain sensor and actuator data instantly and manage Various scheduled alarms. It incorporates three buttons to interest the different screens of the control unit available to the less than the following functions: Temperature control of the coolant, from the upper differential of the liquid coolant, of the lower differential of the coolant, of the compressor start time after activation detection, of high and low temperature for the exchanger fan of refrigerating heat, high and low temperature for pump regulation, high temperature alarm in the coolant probe, high pressure alarm, Low pressure alarm, low level buoy alarm, and of the alarm for excess temperature in the fan of the refrigerator exchanger

The control unit is connected by a RS232 port, USB to PC.

The subjection of all these elements described It is done by mechanical joining means such as screws, flanges, staples or other suitable means, provided that it guarantees a strong fixation and does not transmit vibrations to the mechanical system, that is thermally insulated to prevent mechanical transmission of heat to the containment system, which supports the efforts mechanical, have tightness and support the pressures of job.

The principle of operation of the invention proposal is as follows: The circuit is divided into two parts, the main absorption circuit and the secondary circuit or evacuation. The union of these two parts is done through a component called heat exchanger, which starts at the end of the absorption circuit and ends at the beginning of the circuit evacuation.

The coolant circuit blocks of absorption, anchored by appropriate means of attachment to the components to cool, absorb heat from the element to dissipate in a mechanical or static way and the block yields the temperature by transmission to the liquid that circulates inside. As the transmitting liquid goes through one or several blocks of transmission, absorbs more heat from the components. This liquid is driven by a pump that receives the liquid from a tank or the same tank of the exchanger if it is submerged. When the transmitting liquid has finished circulating through the last block, goes through the heat exchanger that yields its temperature at the second evacuation circuit described below. The liquid leaves the heat exchanger and goes through the components.

The heat evacuation circuit is a system refrigerated gas refrigeration, closed, containing a gas refrigerant that evaporates at very low temperatures, depending on the pressure to which it is exposed. Starting from the heat exchanger, in which in one of its parts there is a temperature transmitting liquid high, corresponding to the absorption circuit, and in the on the other hand there is a refrigerant gas in a gaseous state that absorbs the heat provided by the exchanger, due to its pressure and temperature characteristics, it turns out that this gas, a Once it has passed through the exchanger, it reaches the compressor through the low pressure inlet, where it is compressed and altered in its pressure, and therefore its characteristics are mechanically varied physical pressure temperature, exits through the high pressure zone of the compressor and is conducted to an evacuation condenser of cooling heat that by the action of a fan cools the gas liquefying it, cooling the heat coming from the circuit absorption.

Once the heat of the gas has been evacuated, it leads to a dehydrator filter that retains the possible particles and moisture that exist in the refrigeration circuit, from said filter passes to the capillary or restrictor that forces the gas to change pressure, the gas then absorbs heat by changing state, the capillary or restrictor links with the exchanger of heat, restarting the refrigeration circuit from the beginning.
