Problems solved by technology

However, when the above-mentioned technology supplies a large-area heating coil or freeze-drying warehouse radiant coil with a single host, the laying amount of the compressed medium circulation coil is too large, which leads to an excessively large compressed medium circulation system. Therefore, the cost of the pipeline High, large filling volume of compressed medium, resulting in increased cost, difficult distribution of compressed medium, unbalanced liquid return after liquefaction, and too complicated control system when the distribution balance and liquid return balance are satisfied, and an overly complex control system will bring There are problems such as increased manufacturing costs, high installation and maintenance costs, and poor operational stability.

Embodiment 1

[0020] This embodiment is a device for extracting the phase change heat of compressed steam for radiation heat transfer with only one set of heat pipe assemblies on the intake communication pipe. Its specific structure is as figure 1 shown.

[0021] A group of heat pipe assemblies is fixedly connected to the air intake connecting pipe 3. A group of heat pipe assemblies consists of a heat pipe 1 and a sleeve 2. The heat pipe 1 is composed of a heating section 1b and a condensation section 1a. One end of the condensation section 1a is sealed, and the other end is sealed. It communicates with one end of the heating section 1b, and the other end of the heating section 1b has an end cover 7; one end of the sleeve 2 is fixed at the intersection of the heating section 1b and the condensation section 1a in the heat pipe, and the other end of the sleeve 2 is connected to the air inlet The connecting pipe 3 is welded together, and the two are connected; the inner diameter of the air in...

Embodiment 2

[0025] In this embodiment, at least two sets of heat pipe assemblies are installed on the air intake communication pipe, which is a device for extracting phase change heat of compressed steam for radiation heat transfer with multiple sets of heat pipe assemblies. Its specific structure is as figure 2 shown.

[0026] There are 7-12 sets of heat pipe assemblies fixedly connected to the air intake communication pipe 3, and the structure of each heat pipe assembly and the connection method with the air intake communication pipe are the same as those in Embodiment 1.

[0027] A liquid accumulation baffle 5 is welded in the intake communicating pipe 3, and the distance between the two liquid accumulation baffles 5 can be determined according to specific conditions. A drain pipe interface 6 is arranged on the intake communication pipe 3 between the two liquid accumulation baffles. The drain pipe interface 6 can also be arranged on the air intake communication pipe 3 between a liqu...

Abstract

A device capable of extracting heat of phase transformation of compressed steam for radiative heat transfer adopts the structure that each group of heat pipe component is composed of a heat pipe and a sleeve; each heat pipe comprises a heating section and a condensation section, one end of the condensation section is sealed, the other end of the condensation section is communicated with one end of the heating section, and an end cover is arranged at the other end of the heating section; one end of each sleeve is welded at the joint of the heating section and the condensation section of the corresponding heat pipe, and the other end is welded together with an air-in communicating pipe; a hydrops baffle, as well as a liquid discharge pipe interface, is arranged in each air-in communicating pipe; and one end of each air-in communicating pipe is connected with the corresponding end cover, and an interface connected with a compressed steam delivery pipe is arranged at the other end. In theinvention, water or other liquid transportation can be avoided, so a huge heat exchange system and a delivery pipe net for heating liquid are prevented, the power consumption during the liquid transportation is also avoided, waterway frost cracking can also be prevented, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a heating and heating device which adopts phase change heat extracted from compressed steam for radiation heat transfer. Background technique [0002] At present, with the rapid development of technological innovation and manufacturing technology, in the field of heat pump compressors, frequency conversion and digital scroll compressors have come out, which can operate stably at outdoor temperatures below -25°C and have a high operating energy efficiency ratio. It has opened up a new way for the use of air source heat pumps in the heating field; the development of high-temperature circulating compression medium and high-temperature heat pump units has been successful, and the exhaust temperature and condensation temperature of heat pumps have been greatly increased (up to 100 °C or more), which has greatly expanded the application of heat pumps. The scope of application provides a technical basis for the popularization and use ...
