Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical equipment, and in particular to a heat dissipation system for cooling closed equipment based on an absorption refrigeration system. Background Art

[0002] With the development of science and technology, various electromechanical equipment have entered people's lives and gradually changed people's lifestyles. While these electromechanical equipment convert other forms of energy into mechanical energy, part of the energy will be lost in the form of waste heat. After the accumulation of this waste heat, it will inhibit the operation of the equipment, forming a vicious cycle, so timely discharge of waste heat has become a top priority.

[0003] How to effectively dissipate heat for closed electromechanical equipment has always been a difficult problem. Among them, air cooling and water cooling are good heat dissipation methods, but their limitations are obvious, limited by ventilation, water sources and other working environments.

[0004] In view of the above problems, the present invention mainly utilizes absorption refrigeration to absorb the waste heat generated by the equipment, uses the working fluid pair as the cooling medium, cools the equipment, and reduces the ambient temperature of the equipment. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems existing in the prior art and to provide a heat dissipation system for cooling closed equipment based on an absorption refrigeration system.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A heat dissipation system for cooling a closed device based on an absorption refrigeration system comprises a closed device and a self-contained heat circulation system on the closed device. The heat dissipation system also comprises an absorption refrigeration system. The absorption refrigeration system cyclically absorbs waste heat generated by the closed device through absorption refrigeration using a heat-absorbing medium, and assists in cooling the self-contained heat circulation system and the closed device through external condensation.

[0008] Furthermore, the absorption refrigeration system consists of an absorption refrigeration condenser, a refrigeration end bend pipe serving as an absorber, a liquid storage tank serving as a generator, a nested pipe serving as an evaporator, and a corresponding heat-absorbing medium, wherein the liquid storage tank is connected to the nested pipe via a liquid storage connecting pipe, the nested pipe is connected to the absorption refrigeration condenser via a condensation air inlet pipe and a condensation air inlet port, the absorption refrigeration condenser is connected to the refrigeration end bend pipe via a condensation liquid outlet pipe, and the refrigeration end bend pipe is connected to the liquid storage tank to form an absorption refrigeration circuit.

[0009] Furthermore, the heat absorbing medium includes but is not limited to a water-based working fluid pair, an ammonia-based working fluid pair, an alcohol-based working fluid pair or a Freon-based working fluid pair.

[0010] Furthermore, the nested pipes are nested on the exhaust / drain pipes of the working equipment in the closed equipment to facilitate the absorption of waste heat.

[0011] Furthermore, the refrigeration end bent pipe is arranged at the radiator in the self-contained heat circulation system to facilitate auxiliary cooling.

[0012] Furthermore, the absorption refrigeration condenser and the liquid storage tank are arranged outside the closed equipment to facilitate heat dissipation.

[0013] Furthermore, the absorption refrigeration condenser is provided with fins and a fan to improve the heat dissipation performance.

[0014] The beneficial effects of the present invention are:

[0015] 1. It can effectively dissipate the waste heat of the equipment, which is more energy-saving than simple air cooling and water cooling.

[0016] 2. It can work normally even in areas with scarce water resources. The absorption refrigeration composed of the working fluid and its own heat circulation system are two closed loops.

[0017] 3. No external water pump is required to make the working fluid circulate in a loop.

[0018] 4. Since the cooling medium used is a working fluid with a high energy efficiency ratio COP, the theoretical cooling effect is better than the heat dissipation performance of a simple water cooling or air cooling system. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] Reference Figures 1 to 5 As shown, a heat dissipation system for cooling a closed device based on an absorption refrigeration system includes a closed device 18 and a self-contained heat circulation system 19 on the closed device 18. The heat dissipation system also includes an absorption refrigeration system 20. The absorption refrigeration system 20 cyclically absorbs the waste heat generated by the closed device 18 through absorption refrigeration with a heat-absorbing medium, and assists in cooling the self-contained heat circulation system 19 and the closed device 18 by external condensation.

[0027] The absorption refrigeration system 20 is composed of an absorption refrigeration condenser 5, a refrigeration end elbow 8 as an absorber, a liquid storage tank 10 as a generator, a nested pipe 12 as an evaporator and a corresponding heat absorption medium, wherein the liquid storage tank 10 is connected to the nested pipe 12 through a liquid storage connecting pipe 17, the nested pipe 12 is connected to the absorption refrigeration condenser 5 through a condensation air inlet pipe 15 and a condensation air inlet port 16, the absorption refrigeration condenser 5 is connected to the refrigeration end elbow 8 through a condensation liquid outlet pipe 13, and the refrigeration end elbow 8 is connected to the liquid storage tank 10 to form an absorption refrigeration circuit.

[0028] The enclosed device 18 is composed of a closed box shell 9 and a working device arranged in the closed box shell 9. The working device is connected to the corresponding functional device, such as the combination of the diesel engine 3 and the generator 7, which is a pair of working devices and functional devices. The heat source is mainly the waste heat generated by the diesel engine 3, and the diesel engine 3 is discharged to the outside through the exhaust filter and the corresponding exhaust pipe.

[0029] The self-contained heat circulation system 19 is composed of a self-contained heat circulation water pipe 1, a self-contained heat circulation water pump 2, a self-contained heat circulation radiator 11 and corresponding coolant, and forms a simple heat circulation loop passing through the working equipment with the self-contained heat circulation radiator 11->self-contained heat circulation water pipe 1->self-contained heat circulation water pump 2->self-contained heat circulation water pipe 1->self-contained heat circulation radiator 11 to cool the working equipment.

[0030] The heat absorbing medium includes but is not limited to a water-based working fluid pair, an ammonia-based working fluid pair, an alcohol-based working fluid pair or a Freon-based working fluid pair, and the principle is a working fluid pair composed of a high-boiling point absorbent and a low-boiling point refrigerant.

[0031] The nested pipe 12 is nested on the exhaust / drain pipe of the working equipment in the closed device 18 to absorb waste heat. In this embodiment, taking the diesel engine 3 as an example, the nested pipe 12 can be nested on the exhaust pipe of the diesel engine 3.

[0032] The cooling end bend pipe 8 is arranged at the radiator in the self-contained heat circulation system 19 to facilitate auxiliary cooling. In this embodiment, the cooling end bend pipe 8 is arranged at the self-contained heat circulation radiator 11.

[0033] The absorption refrigeration condenser 5 and the liquid storage tank 10 are arranged outside the closed device 18 to facilitate heat dissipation.

[0034] The absorption refrigeration condenser 5 is provided with fins and a fan 14 to improve the heat dissipation performance.

[0035] Working process and principle of the present invention

[0036] In this embodiment, the heat absorbing medium is an ammonia solution as the working medium, and the diesel engine 3 is taken as the working device in the closed device 18. The working process of the absorption refrigeration circuit formed by the absorption refrigeration system 20 is as follows: the ammonia solution stored in the liquid storage tank 10 enters the nested pipe 12 through the liquid storage connecting pipe 17, and the ammonia solution absorbs the residual heat in the closed device 18 and evaporates and rises. Water has a higher boiling point than liquid ammonia. Most of the water vapor will condense and reflux when passing through the condensation inlet pipe 15, and the remaining ammonia will continue to move upward and enter the absorption refrigeration condenser 5 through the condensation inlet port 16 for condensation. The condensed liquid ammonia will enter the refrigeration end elbow 8 through the condensation liquid outlet pipe 13 to cool the closed device 18. The ammonia liquid after absorbing heat will continue to flow downward and mix with the water in the liquid storage tank 10 to release heat.

[0037] In another circulation loop, the coolant in the self-contained heat circulation radiator 11, which is assisted in cooling by the refrigeration end bend pipe 8, enters the diesel engine 3 from the self-contained heat circulation water pipe 1 under the drive of the self-contained heat circulation water pump 2, and is cooled, and then flows into the self-contained heat circulation radiator 11 for a simple heat cycle.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
