Description
技术领域technical field
本实用新型属于余热回收，传热、传质技术领域，特别涉及一种气液脉动热管换热器。The utility model belongs to the technical field of waste heat recovery, heat transfer and mass transfer, in particular to a gas-liquid pulsating heat pipe heat exchanger.
背景技术Background technique
目前，很多能源利用领域，包括一些重点行业，确实存在着热回收效率不高，回收不够科学、合理和在小传热温差情况下的热回收对于常规换热器无法实现的情况。以上情况，有些是考虑设备的腐蚀等因素，而不能将排放介质温度降低到预期的水平，如电站锅炉的烟气排放；有些是换热设备效率低，而无法将排放介质温度降到预期的水平，如工业锅炉和石油、冶金、化工、医药等行业的相关热介质的排放；也有些是考虑热排放量比较少，而不予回收的，如空调以及汽车尾气等的排放；还有些虽然量大，但排放介质的温度较低，采用常规换热设备，即使资金投入较大也很难建立有效传热过程的，如火电厂的循环冷却水或空冷岛的冷却空气热回收等。At present, in many energy utilization fields, including some key industries, there are indeed situations where the heat recovery efficiency is not high, the recovery is not scientific and reasonable, and the heat recovery under the condition of small heat transfer temperature difference cannot be realized by conventional heat exchangers. In some of the above situations, the temperature of the discharge medium cannot be lowered to the expected level due to factors such as corrosion of the equipment, such as the flue gas discharge of the power plant boiler; some are due to the low efficiency of the heat exchange equipment, and the temperature of the discharge medium cannot be reduced to the expected level level, such as the discharge of industrial boilers and related heat media in petroleum, metallurgy, chemical, pharmaceutical and other industries; The amount is large, but the temperature of the discharge medium is low. Using conventional heat exchange equipment, it is difficult to establish an effective heat transfer process even if the capital investment is large, such as circulating cooling water in thermal power plants or cooling air heat recovery in air-cooled islands.
脉动热管的脉动频率远远高于传统热管内的汽液闭合循环频率，同时，其工作介质与热管壁面间的换热过程也因受到剧烈脉动流的作用而大大强化。另外，脉动热管还具有结构简单、不需要毛细芯，有利于降低成本，加热位置和加热方式不受限制(常用的重力热管必须底部加热)；可以随意弯曲，适用范围广；管径小，重量轻，易于实现小型化和启动迅速等突出优点。The pulsation frequency of the pulsating heat pipe is much higher than the frequency of the closed vapor-liquid cycle in the traditional heat pipe. At the same time, the heat exchange process between the working medium and the wall of the heat pipe is also greatly enhanced by the violent pulsating flow. In addition, the pulsating heat pipe also has a simple structure and does not require a capillary core, which is beneficial to reduce costs. The heating position and heating method are not limited (the commonly used gravity heat pipe must be heated at the bottom); it can be bent at will and has a wide range of applications; the pipe diameter is small and the weight Light, easy to achieve miniaturization and quick start and other outstanding advantages.
现有的换热器多采用翅片进行换热，随着热管技术的发展将热管与翅片结合来提高换热效果的换热器也越来越受到欢迎，本实用新型是将翅片与脉动热管相结合，组成气液脉动热管换热器。Existing heat exchangers mostly use fins for heat exchange. With the development of heat pipe technology, heat exchangers that combine heat pipes and fins to improve heat exchange effects are becoming more and more popular. The utility model combines fins with The pulsating heat pipes are combined to form a gas-liquid pulsating heat pipe heat exchanger.

本实用新型涉及一种气液脉动热管换热器，如图1、2、所示，属于余热回收，传热、传质技术领域。包括箱体1、气液脉动热管2。箱体1由上箱体3，下箱体4，隔板5组成，上箱体3，下箱体4，隔板5通过连接螺栓6相连接，脉动热管2穿过隔板5，贯穿于上箱体3和下箱体4，位于上箱体3部分带有翅片，脉动热管2是由80根内径小于5mm的U型金属管通过首尾相连成闭合管束，呈4×20交错布置。上箱体3两侧设有风口7，箱体4设有进水口8和出水口9。风口7处可进一步设置风扇。The utility model relates to a gas-liquid pulsating heat pipe heat exchanger, as shown in Figures 1 and 2, and belongs to the technical fields of waste heat recovery, heat transfer and mass transfer. It includes a box body 1 and a gas-liquid pulsation heat pipe 2 . The box 1 is composed of an upper box 3, a lower box 4, and a partition 5. The upper box 3, the lower box 4, and the partition 5 are connected by connecting bolts 6. The pulsating heat pipe 2 passes through the partition 5 and runs through the The upper box 3 and the lower box 4 are located on the upper box 3 and have fins. The pulsating heat pipe 2 is composed of 80 U-shaped metal tubes with an inner diameter of less than 5mm connected end to end to form a closed tube bundle, which is arranged in a 4×20 staggered manner. Both sides of the upper box body 3 are provided with air outlets 7 , and the box body 4 is provided with a water inlet 8 and a water outlet 9 . A fan can be further arranged at the tuyere 7.
热流体通过箱体底部的进水口8进入下箱体4，以对流换热为主将热量传给脉动热管2后经出水口9流出，脉动热管2吸收热量后，其管内流体呈振荡形式，将热量传递给上箱体3的冷凝段，箱体3两侧设有风口7，位于冷凝段的脉动热管2通过翅片将热量散出。The hot fluid enters the lower box body 4 through the water inlet 8 at the bottom of the box body, mainly transfers heat to the pulsating heat pipe 2 through convective heat exchange, and then flows out through the water outlet 9. After the pulsating heat pipe 2 absorbs heat, the fluid in the tube is in the form of oscillation, and the The heat is transferred to the condensation section of the upper box body 3, and the air outlets 7 are arranged on both sides of the box body 3, and the pulsating heat pipe 2 located in the condensation section dissipates the heat through the fins.
目前余热回收装置的强化换热措施主要采用翅片和肋板等传统方法，翅片换热器的主要缺点是结构复杂，加工复杂，阻力大，肋板换热器的主要缺点是沿肋高方向温度不同，换热效果差，成本高等缺点。现有的脉动热管技术只是将单个热管应用到传热领域，本实用新型气液脉动热管换热器的主要优点是将脉动热管与翅片有机结合，组成气液脉动热管换热器，由于脉动热管的高效传热性能和翅片，使换热器空气(或烟气)侧的传热过程得到强化，同时，脉动热管取代了翅片结构，也相应减少了空气(或烟气)侧的流动阻力。所以相对现有的脉动热管技术，气液脉动热管换热器的换热效率大大提高。通过实验数据表明，采用气液脉动热管换热器，其换热效果要比单个热管换热器换热效果提高5％～10％。因此，相对于传统的换热器，本实用新型安装灵活，热回收效率高，结构简单，造价低，不受季节和地域的限制，适用范围广。At present, the enhanced heat exchange measures of waste heat recovery devices mainly adopt traditional methods such as fins and rib plates. The main disadvantages of fin heat exchangers are complex structure, complicated processing, and large resistance. The direction temperature is different, the heat transfer effect is poor, and the cost is high. The existing pulsating heat pipe technology only applies a single heat pipe to the field of heat transfer. The main advantage of the utility model gas-liquid pulsating heat pipe heat exchanger is that the pulsating heat pipe and fins are organically combined to form a gas-liquid pulsating heat pipe heat exchanger. Due to the pulsation The high-efficiency heat transfer performance of the heat pipe and the fins strengthen the heat transfer process on the air (or flue gas) side of the heat exchanger. At the same time, the pulsating heat pipe replaces the fin structure, which also reduces the flow resistance. Therefore, compared with the existing pulsating heat pipe technology, the heat exchange efficiency of the gas-liquid pulsating heat pipe heat exchanger is greatly improved. Experimental data show that the heat exchange effect of the gas-liquid pulsating heat pipe heat exchanger is 5% to 10% higher than that of a single heat pipe heat exchanger. Therefore, compared with the traditional heat exchanger, the utility model has the advantages of flexible installation, high heat recovery efficiency, simple structure, low cost, not limited by seasons and regions, and has a wide range of applications.
