Abstract

The utility model discloses a heat-storage wall body for a sunlight greenhouse, which comprise a wall main body, wherein the wall main body is formed by mixedly building phase-change material block bodies and wall brick bodies. The phase-change material block body can be built inside the wall brick body, and also can be wrapped inside an inner layer. The phase-change material block body is of a graphite body or a paraffin block body. The heat-storage wall body is generally used for building a rear wall of the sunlight greenhouse; with the heat-storage wall body, the heat of the sunlight in the daytime can be stored and can be released at night so as to maintain the balance of the indoor temperature as far as possible, thereby greatly improving the indoor temperature of the sunlight green house at night in winter, and being free from running expense, and having simple structure and convenient construction.

Description

The heat accumulating type body of wall that is used for heliogreenhouse

Technical field

The utility model relates to a kind of heat accumulating type body of wall that is used for heliogreenhouse.

Background technology

Along with agriculture of city type in China's fast development, agricultural facility fast developments such as large-size intelligentized greenhouse are got up, but traditional heliogreenhouse is because cost is low, advantage such as operating cost is low is still received by vast agriculture application person.Owing in the most of regional heliogreenhouse in the south and the north, generally do not take auxiliary heating system, the interior temperature of heliogreenhouse at night in time in winter is generally on the low side, influenced plant growing, thereby limited the service time of heliogreenhouse, reduced the heliogreenhouse utilization rate, hindered the heliogreenhouse large tracts of land and promoted.

Summary of the invention

The purpose of this utility model provides a kind of heat accumulating type body of wall that is used for heliogreenhouse, utilizes it heat of daylight can be stored, and is discharging to evening, to keep the balance of interior temperature as much as possible.

For achieving the above object, the utility model is taked following design scheme:

A kind of heat accumulating type body of wall that is used for heliogreenhouse comprises the wall body, and described wall body is mixed to build to construct by phase-change material block and wall brick body and forms.

Described phase-change material block can be built in the wall brick body; Can also be wrapped in the internal layer.

Described phase-change material block is graphite or paraffin block.

The heat accumulating type body of wall that the utility model is used for heliogreenhouse generally is used to construct the back wall of heliogreenhouse, also can use in other field.

The utility model has the advantages that: improve heliogreenhouse nocturnal temperature in interior winter, no operating cost, simple in structure, easy construction greatly; Energy-conservation, under the prerequisite of consumes energy not, effectively improve the temperature in greenhouse in the winter time night, thereby provide guarantee for ensured sustained development, the high yield of agricultural production.

The specific embodiment

The heat accumulating type body of wall wall body wall body 1 that the utility model is used for heliogreenhouse is mixed to build to construct with wall brick body 102 by phase-change material block 101 and forms.

Shown in Fig. 2 a, Fig. 2 b, described phase-change material block 101 can be built in the wall brick body 102, and it can evenly distribute, and also can irregularly distribute.

As shown in Figure 3, described phase-change material block 101 can also be made monomer brick shape, be wrapped in the internal layer of wall brick body 102, and all around all by 102 layers of encirclement of wall brick body.

The utility model adds volume of phase-change material within the walls or makes the fragment of brick form and mix with wall body brick and build by laying bricks or stones behind heliogreenhouse, by the variation of phase-change material phase place, reach the storage of solar energy on daytime was got up to be discharged into purpose in the heliogreenhouse at night.

Described phase-change material block is graphite or paraffin block.Daytime, phase-change material such as solid graphite or paraffin was by absorbing solar heat liquefy graphite or paraffin, can reduce day temperature in the heliogreenhouse simultaneously; Nocturnal temperature is reduced to the freezing point of phase-change materials such as graphite or paraffin, and phase-change materials such as graphite or paraffin are changed solid-state by liquid state, and release heat heats temperature in the heliogreenhouse night thereby reach simultaneously.

During daytime in winter, shine upon heliogreenhouse, interior temperature raises, within the walls solid graphite or phase-change material such as paraffin mass absorbs solar energy behind the heliogreenhouse, after interior temperature reaches heliogreenhouse within the walls during phase-change material such as graphite or paraffin 1 condensing temperature, phase-change materials such as graphite or paraffin 101 liquefy graphite or paraffin.Simultaneously can reduce heliogreenhouse interior temperature on daytime.Night, interior temperature began to reduce, but when interior temperature was reduced to liquid graphite or paraffin solidification temperature, liquid graphite or paraffin began to solidify, simultaneously release heat in heliogreenhouse, improve temperature in the heliogreenhouse, liquid graphite or paraffin become solid graphite or paraffin simultaneously.Phase-change material such as graphite or paraffin is finished a solid-state-liquid state-solid-state change-over period like this, finishes a transfer of heat simultaneously and delay time to discharge.

The utility model also can be improved phase-change materials such as the graphite that adopts or paraffin, as being that paraffin, polyolefin, thermoplastic elastomer (TPE) and the inorganic filler of 16-20 is mixed and made into paraffin phase change material by carbon number.Form difference, its phase transition temperature is also different.According to the difference of south and each local actual temp of northern major region, phase transition temperature generally is controlled between 17 ℃～25 ℃, room temperature can be remained between 18-20 ℃.

Problems such as phase-change material adds behind the heliogreenhouse within the walls, has well solved Solar Greenhouse in Winter heating operation expense height, and interior temperature is on the low side effectively reduce heliogreenhouse on daytime in summer simultaneously.

The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit claim of the present utility model.
