Abstract

The utility model discloses a single heat-pipe-type flat plate collector, which is different from the prior art for: a heat absorption body mainly includes a longitudinal main pipe, a connection pipe, a bypass pipe, a connection branch pipe and a coiled pipe; the middle part of the pipe on the upper part of the coiled pipe is communicated with one end of the longitudinal main pipe through the connection pipe, and the other end of the longitudinal main pipe is communicated with a heat radiation pipeline of a heat radiation-body part; each elbow of the coiled pipe is communicated with two bypass pipes that are arranged at both sides of the coiled pipe through the connection branch pipe; both the front end and the tail end of the coiled pipe are communicated with the bypass pipe; the lower end of the two bypass pipe is bent and communicated with each other, and the upper end is bent to be communicated with the longitudinal main pipe or the upper end of the bypass pipe is directly communicated with the heat radiation pipeline of the heat radiation-body part. The collector is applied to the systems such as the solar heater, the heat insulation plate, the closed heat radiation system, and the like. The collector has the advantages of low startup temperature and rapid heat conduction, and can prevent from being frozen, and has high heating efficiency; the heat collector is more convenient to be installed, maintained and repaired.

Description

Single heat pipe-type flat plate collector

Technical field:

The utility model relates to heat collector, especially a kind of single heat pipe-type flat plate collector that adopts novel absorber.

Background technology:

Existing heat collector mainly contains two kinds: 1, vacuum tube collector; 2, heat pipe-type flat plate collector.Wherein, vacuum tube collector can be divided into glass vacuum pipe heat collector and heat pipe vacuum tube hot collector again.Though the single heat collector collecting efficiency of vacuum tube collector height, by several, tens and even tens heat collectors of forming, structure is not compact, and the ratio of the absorber area and the gross area is less, and total collecting efficiency is not high.Because the thermal-collecting tube of heat collector directly gos deep in water tank or the header, the length of water tank is decided by the radical of thermal-collecting tube, and radical is many, and water tank is long, and interface is also many, causes that easily to soak leak source many.In addition, the water in the vacuum tube collector can not be emptied completely, and when water quality can not guarantee, easily precipitation, incrustation etc. in the pipe influenced Heat-collecting effect, and installation, maintenance, repair are all not very convenient; Existing heat pipe-type flat plate collector, though heat transfer medium does not enter in the heat collector, avoided freezing and defect such as heat transfer medium precipitates in heat collector, incrustation, but it is many that it has radical equally, water tank is long, and interface is many, makes easily to soak the many shortcomings of leak source, and under the situation of portion of hot tube failure, keep in repair more difficult.

The utility model content:

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of single heat pipe-type flat plate collector that adopts novel absorber is provided.

The utility model is realized with following method:

A kind of single heat pipe-type flat plate collector, comprise the radiator part, transparent cover plate, thermal insulation layer and shell, unlike the prior art be, the absorber of heat collection body part is mainly by vertical house steward, tube connector, bypass pipe, connecting branch and coiled pipe are formed, the pipe middle part on coiled pipe top is communicated with by the end of a tube connector with vertical house steward, vertically house steward's the other end is communicated with the hot channel of radiator part, each elbow of coiled pipe is communicated with two bypass pipes that are arranged on the coiled pipe both sides by connecting branch respectively, the two ends end to end of coiled pipe are communicated with bypass pipe, the lower end bending butt joint of two bypass pipes also is communicated with, and the upper end bending is communicated with vertical house steward or the bypass pipe upper end directly is communicated with the hot channel of radiator part.

To be pumped into 1.3 * 10 in the absorber ^-1～1.3 * 10 ^-4Fill with an amount of liquid refrigerant after the negative pressure of Pa, be sealed in the pipe, place with the inclination angle that ground keeps certain, system just becomes a gravity assisted heat pipe.

During work, at first, heat collection body part absorber be subjected to radiation and obtain heat, the temperature in thermal-arrest space raises, liquid refrigerant in the absorber pipe flashes to gaseous working medium from the heat absorption of absorber tube wall, gaseous working medium rises to the heat radiation system along coiled pipe, bypass pipe and vertical house steward, by the heat release of heat radiation system, condenses into liquid state by gaseous state, under the effect of gravity, down reflux, simultaneously, the liquid refrigerant of backflow flashes to gaseous working medium from the tube wall heat absorption again.Like this, working medium is constantly carried out gas-liquid phase transition and is circulated in system, realized heat collection, transmit and distribute process.

The utility model can be applicable in the systems such as cooling system in solar water heater, thermal insulation board, totally-enclosed space.

The utility model has the advantages that: original heat pipe-type flat plate collector and heat pipe vacuum tube hot collector are made up of many heat pipes, change over the single heat pipe-type flat plate collector of the totally-enclosed system formula that a heat collection body that is made of novel absorber and radiator form, it has common flat plate collector compact conformation, endotherm area and the big advantage of gross area ratio, there is the heat pipe start-up temperature low again, conduct heat rapidly, can avoid freezing advantage, the thermal efficiency is higher; Between radiator portion and thermal-arrest part by realization separates with the bypass pipe ways of connecting with vertical house steward, so radiator portion and thermal-arrest part can be selected the suitable material of heat conductivility respectively for use and adopt various augmentation of heat transfer measures to be made into various suitable shape and size, thereby reduce its cost of manufacture by optimal design; The utility model is a heat pipe on the whole, and its breakage is easy to find, also is easy to repair, and the installation, modification maintenance and repair of heat collector is convenient.
