Abstract

The utility model relates to a movable low-temp freezer assembling board block. The polyphenyl assembling board block of the same class at present has a low price, but the thermal insulating property is not good. The thermal insulating property of the polyurethane assembling block is good, but the price is high. The structure of the utility model is that a polyphenyl plate is clamped between two iron sheets, a polyurethane foam material layer having a hard bubble structure is clamped among both sides of the polyphenyl plate and the iron sheets, and the cost is low. The movable low-temp freezer assembling board block has the corresponding price with the exiting polyphenyl plate assembling block, but the thermal insulating property is superior to the exiting polyurethane assembly board block. The temperature of the assembly low-temp freezer can be kept in-24 DEG, and the requirements of the low-temp freezer is exceeded.

Description

Packaged type low-temperature cold store assembly unit plate

The utility model belongs to the assembly unit plate of packaged type low-temperature cold store.

The packaged type freezer is to adopt prefabricated plate assembled.Existing this assembly unit plate structure has following several: (1), shown in Figure 3, the polyphenyl plate of the soft bubble structure of two-layer iron sheet 1 therebetween one deck; (2), shown in Figure 4, the folder one deck closed pore polyurethane foam material layer of structure that hard bubbles between the two-layer iron sheet 1; The polyphenyl plate material that presss from both sides between preceding a kind of assembly unit plate iron sheet is more cheap, and sandwich after having suppressed, cost is lower, but its coefficient of thermal conductivity is higher, temperature of ice house with its assembly unit can only reach-8 ℃--and 15 ℃, the structure of second kind of polyurethane foam material layer is the closed pore structure of hard bubbling, be that its abscess great majority seal, coefficient of thermal conductivity is low, temperature of ice house with its assembly unit can reach-18 ℃, but its cost is about the 160-180% of polyphenyl sheet material, and the polyurethane foam material layer of this structure assembly unit plate is that the scene pours into foaming formation between the two-layer iron sheet, very easily cause some gross blow holes because foaming is inhomogeneous,, can not give full play to the advantage of polyurethane material so influenced its heat-insulating property greatly.

The utility model aims to provide a kind of good heat insulating, packaged type low-temperature cold store assembly unit plate that cost is low.

For achieving the above object, the utility model adopts following structure, accompanies polyphenyl plate between two iron sheets, it is characterized in that: the polyurethane foam material layer that accompanies the structure of hard bubbling between described polyphenyl plate and both sides iron sheet respectively.

The utility model adds one deck polyurethane rigid foam material layer between polyphenyl plate and iron sheet, the foamed material layer of this structure is easy to adopt the method for in-situ spraying foaming to make, both but p-poly-phenyl plate and iron sheet played adhesive effect for it, itself also form simultaneously one deck uniform in foaming, insulation layer that coefficient of thermal conductivity is low, made full use of the characteristic of polyurethane material good heat insulating.In addition, this two-layer rigid foam material can also improve the intensity of plate greatly, so during with this plate assembly unit freezer, the corner part can directly be connected and fixed with screw, has saved the angle bar frame.The cost of the utility model plate assembly unit freezer is with suitable with the plate cost of existing iron sheet folder polyphenyl plate, only be 60-70% with iron sheet folder polyurethane foam material plate cost, and its heat-insulating property has surpassed the latter, freezer minimum temperature with its assembly unit can remain on-24 ℃, has surpassed the requirement of low-temperature cold store.Therefore the utlity model has that cost is low, good heat insulating, advantage that intensity is high.

The embodiment explanation:

Present embodiment accompanies polyphenyl plate 2 between two iron sheets 1, accompany the polyurethane foam material layer 3 of the structure of hard bubbling between polyphenyl plate 2 and both sides iron sheet respectively.

Its manufacture process is: spray earlier one deck polyurethane foam material on iron sheet equably, then prefabricated polyphenyl plate is pressed and be connected as a single entity with iron sheet is bonding thereon, expanded material had both played adhesive effect, the effect that the rigid foam material layer of its initiation simultaneously has good heat-insulating property and improves plate intensity, and the polyurethane rigid foam material layer abscess that processes like this is even, good heat insulating can be brought into play the little advantage of its coefficient of thermal conductivity more fully.

With this plate assembly unit 13m ³The freezer cost is about 20,000 yuan, and the freezer that presss from both sides the same volume of slope piece assembly unit of polyurethane foam material with iron sheet then needs about 30,000 yuan.

Claims

1, packaged type low-temperature cold store assembly unit plate adopts following structure: accompany polyphenyl plate between two iron sheets, it is characterized in that, accompany the polyurethane foam material layer of the structure of hard bubbling between described polyphenyl plate and the both sides iron sheet respectively.
