Description

A kind of heat pipe type solar flat plate collector

Technical field

The utility model relates to solar energy heat utilization field, is specifically related to a kind of heat pipe type solar flat plate collector.

Background technology

Heat pipe, as a kind of phase-change heat transfer element, has high thermal conductivity, has been widely used in the fields such as microelectronics, Aero-Space.Development along with solar energy heat utilization technology, heat pipe is applied to the attention that plate solar collector has obtained numerous enterprises and scholar, heat pipe type solar flat plate collector of the prior art, its main heat transfer element is collector and heat pipe, heat pipe has evaporator section and condensation segment two parts, evaporator section receives solar irradiation, condensation segment and thermal-collecting tube are connected, the Length Ratio of evaporator section and condensation segment is very large, the solar energy that heat pipe absorbs is only taken away by the collector being connected with its one end, the bulk temperature of heat pipe is very high, increase with the heat loss of external environment, during heat pipe normal operation, the aquifer yield of heat collector only guarantees by one section of condensation segment of heat pipe.

At present, heat pipe type solar flat plate collector heat pipe used is one section of evaporation, one section of condensation, and cannot guarantee that heat collector can work under various inclination angles.

Utility model content

The shortcoming and deficiency that in order to overcome prior art, exist, provide a kind of heat pipe type solar flat plate collector.

The utility model adopts following technical scheme:

A kind of heat pipe type solar flat plate collector, comprise cocycle collector, lower circulation collector and be arranged on the heat pipe between upper and lower circulation collector, the upper and lower end of described heat pipe is the upper and lower circulation collector of vertical insertion respectively, described insertion portion is condensation segment, described heat pipe has two sections of condensation segments, is evaporator section between described condensation segment.

Described heat pipe inner wall is liquid sucting core structure.

Described heat pipe outer wall is provided with fin structure.

The beneficial effects of the utility model:

The utlity model has simple in structure, the thermal efficiency is high, aquifer yield is large, reduce heat loss, the advantage that easy for installation and maintenance cost is low.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.

Embodiment

As shown in Figure 2, a kind of heat pipe type solar flat plate collector, comprise cocycle collector 1, lower circulation collector 2 and be arranged on the heat pipe 3 between upper and lower circulation collector, the upper and lower end of described heat pipe is the upper and lower circulation collector of vertical insertion respectively, described insertion portion is condensation segment, described heat pipe has two sections of condensation segments, between two condensation segments, is evaporator section b.The utility model is provided with two sections of condensation segments, has increased condensation area.

As shown in Figure 3, described heat pipe inner wall is liquid sucting core structure 5, heat pipe outer wall is provided with fin structure 4, and the described fin structure that arranges has increased solar radiation area, increases the heat that heat pipe absorbs, between described heat pipe and fin structure, by welding manner, be connected, technique is simple, and heat transfer resistance is little, described liquid sucting core structure, for the absorption of heat-pipe working medium and flow enough driving forces are provided, make heat collector to put inclination angle unrestricted.

As shown in Figure 4, the condensation segment of heat pipe upper/lower terminal is the vertical upper and lower circulation collector inside of inserting respectively, and hydraulic fluid is directly contacted with heat pipe, improves heat-transfer capability.During due to long-term work, heat pipe outer wall may be subject to the corrosion of hydraulic fluid, needs opposite heat tube condensation segment to carry out conservation treatment, is coated with the thin protective layer of last layer by modes such as plating, chemical platings at wall place.

As shown in Figure 1, the course of work of the present utility model is: heat pipe two end portions is condensation segment, between two condensation segments, be evaporator section b, evaporator section absorbs solar radiation, liquid working substance flashes to gas flow heat pipe upper end condensation segment a1, lower end condensation segment a2, condensation segment is due to upper, lower cycle set pipe racks is walked heat Q21, gas working medium condenses into liquid, under the capillary force effect that liquid provides at liquid sucting core structure, be back to evaporator section, compare with conventional heat pipe, the utlity model has two sections of condensation segments, increased condensation area, liquid sucting core structure must have good capillary absorption power, guarantee that liquid working substance is adsorbed on liquid-sucking core and is back to evaporator section.

Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
