Description

Thermoelectric element cooling antifreeze circulation type cooling mat {Peltier element cooling and antifreeze circulation type cooling mat}

The present invention relates to a cold mat that cools the floor by circulating cold antifreeze produced by thermoelectric elements. High-pressure hoses are laid at regular intervals inside the mat and a thin flat ice pack is placed on top to cool the coolant stored in the coolant tank. This relates to a cold mat that cools the surface of the mat by circulating antifreeze (hereinafter referred to as coolant) through a water pump and high-pressure hose.

In general, a mat is used to provide comfort and comfort to the user by supporting the human body when the user rests or sleeps.

In Korea, which is accustomed to the Ondol culture, heating equipment such as electric blankets, electric mats, and hot water mats have been widely distributed for a long time. However, on the other hand, the only product for sleepless tropical nights (sleeping) in the hot summer is the Cool Gel Mat.

It feels a little cool when it first touches the skin, but it has the disadvantage of not being cool after a while as body temperature transfers.

The technical problem to be achieved by the present invention is to solve the problems described above, by laying high-pressure hoses at regular intervals inside the mat and covering (attaching) flat ice packs on them to ensure that the coolant produced in the regulator body is high-pressure. As it circulates along the hose, the cool air of the coolant is transferred to the flat ice pack, providing a thermoelectric element-cooled antifreeze circulation type cold mat with the function of keeping the surface cool.

In addition, if the polarity of the applied voltage supplied to the thermoelectric element is changed or two thermoelectric elements are attached oppositely to the heat sink and electricity is separately supplied from the control member, the coolant contained in the coolant tank becomes hot and circulates to form a heating mat.

In one embodiment, the bottom layer of the mattress part is made of felt, waterproof fabric, high elastic sponge or non-woven fabric treated with bio (dots) to prevent slipping, and the upper outer layer is made of waterproof, water-repellent fabric or general fiber fabric. It is characterized by including being.

In one embodiment, the mattress unit is formed on one side of the mattress unit and further includes an inlet for receiving cooling water from the cooling member.

In one embodiment, a thermoelectric element installed inside the cooling member body to cool the cooling water; A heat sink attached to the heating part of the thermoelectric element to absorb heat generated from the thermoelectric element; A cooling fan that exhausts the absorbed heat to the outside; A coolant tank attached to the thermoelectric element to cool the coolant; An insulating material that is attached between the coolant tank and the heat sink to prevent the heat generated from the heat sink from transferring to the coolant tank, and is also attached to the entire front of the coolant tank to block the cold air in the coolant tank from being released to the outside; Coolant tank containing coolant; A water pump that circulates cold coolant produced in the coolant tank into the mattress through a high-pressure hose; High-pressure hose that circulates coolant; And it is characterized by including a control member that operates the cooling member; and a connection part that connects the high pressure hose.

In one embodiment, by changing the electrode of the thermoelectric element or adjusting it by attaching two thermoelectric elements to the heat sink in opposite directions, the coolant in the tank becomes hot, and the hot coolant can be circulated through a high-pressure hose, which can also be used as a heating mat. It is characterized by

According to the present invention, cold cooling water is circulated through the bottom of the flat ice pack inserted inside the mattress, allowing for a cool, sound sleep and an effect of escaping from tropical nights or heat.

The circulation pump 16 installed at the bottom of the coolant tank 11 has an inlet and an outlet, is driven by electric power, and has a structure in which coolant is sucked in through the inlet and discharged through the outlet. The internal structure will be explained in detail later.

Figure 3 is a diagram showing the external appearance of a cooling member according to an embodiment of the present invention.

Referring to FIG. 3, there is a coolant inlet 14a through which coolant is injected into one upper side of the cooling member, and an air intake port 13-1 through which air is sucked in when the internal cooling fan rotates is formed on one side of the rear side.

A coolant tank 14 is attached to the cold air portion of the thermoelectric element 11 to lower the temperature of the coolant contained inside, and between the heat sink 12 and the coolant tank 14, the heat of the heat sink 12 is transmitted to the coolant tank ( 14), and an insulation material 15 is installed on the entire front of the coolant tank 14 to prevent the temperature of the coolant contained in the coolant tank 14 from being lost to the outside. (Insulating water bottle) (This is the same principle as finishing with insulation to prevent heat from escaping). A water pump 16 that circulates the coolant in the coolant tank 14 into the mat through a high-pressure hose is provided on one side of the lower part of the coolant tank 14, and the coolant discharged through the water pump 16 is discharged through the coolant outlet 20a. ) and while circulating inside the mat 100, the cold air is lost to the flat ice pack, returns to the inlet 20b, and is contained in the coolant tank 14. When the water is cooled again in the coolant tank 14, the water becomes cold again in the coolant tank 14. You lose. The basic SPAC of the thermoelectric element is -60℃~130℃, and if the coolant continues to circulate inside the mat, the surface of the mat is too cold (like the heating function of a car seat that heats up and stops repeatedly), so it circulates and stops at regular intervals. This is repeated, and at this time, the thermoelectric element function continues while the circulation is stopped, and the coolant in the coolant tank 14 continues to be cold. The coolant used here is antifreeze rather than ordinary water, and either a ready-made product suitable for the purpose is used, or it is manufactured according to the purpose using propylene glycol, which is harmless and non-toxic to the human body. When regular water is used as a coolant, if the thermoelectric element drops to a temperature of up to -60℃ through the coolant tank (14), the water freezes and cannot circulate and function properly. Therefore, antifreeze that can withstand even subzero temperatures is used. will be used. In particular, on one side of the inner wall of the coolant tank 14, a plurality of cooling plates or cooling rods are installed to quickly reduce the temperature of the coolant by securing the cross-sectional area of the tank as wide as possible and transferring a large amount of cold air generated from the thermoelectric element 11 to the coolant. -1) is attached. In other words, a cooling plate structured like a car radiator is attached to the inner wall of the coolant tank.

The control member 17, which controls and drives the entire cooling member, is installed on one side of the cooling member 10 and is also manufactured as a remote control for convenience.

The thermoelectric element 11 that produces cold air uses a ready-made product with excellent cooling function and good performance.

The heat sink 12, which absorbs the heat generated from the thermoelectric element 11, uses a ready-made product or is made of copper plate, aluminum, or alloy plate according to the purpose, and the cooling fan 13, which discharges the heat from the heat sink 12 to the outside, is used for the purpose. Use ready-made products that fit your needs. The cooling module and heat sink are explained in detail in FIG. 6.

The coolant tank 14, which contains coolant and cools it, is equipped with a coolant inlet (14-1) on one side of the upper part and is made of copper plate, aluminum or alloy plate with good thermal conductivity, and the internal cooling plate (14-1) is used to heat heat. In order to improve conductivity, it is manufactured to a thickness of 0.5 mm or less. When manufactured as a cooling rod, heat transfer fluid is sealed inside a thin copper plate to improve thermal conductivity.

The insulation material 15 is made of EPP (Expanded Polypropylene), which has excellent insulation effect and bursting strength, by molding and foaming it to suit the purpose. In addition to EPP, materials suitable for the purpose are used.

The water pump 16 uses a ready-made product suitable for its purpose.

Figure 5 is a diagram supplementary to Figure 4.

Referring to Figure 5, the thermoelectric element 11 that produces cold air uses an off-the-shelf product with good performance, and the cooling fan 13 also uses an off-the-shelf product suitable for its purpose. A cooling plate or cooling rod 14-1 is attached to one inner side of the cooling water tank 14, where the thermoelectric element is attached, and an inlet 14a through which cooling water is injected is provided. One side of the tank 14 is provided with a coolant inlet 20b that circulates in the mat, and, although not shown, a coolant outlet fitted with the inlet 16a of the water pump 16 is provided on one lower side.

Figure 6 is a diagram explaining a cooling module according to an embodiment of the present invention.

Referring to FIG. 6, the material of the heat sink 12 is a copper plate (a plate made of copper) with good thermal conductivity, and depending on the purpose, it can be made of a material with better thermal conductivity.

The heat sink 12 is cut to the size of a thermoelectric element (40x40mm) and rolled to a thickness of 0.1 to 0.2mm for shirring.

The heat sink 12 used in the present invention is made by first rolling a hot-rolled copper plate at room temperature or a temperature close to it to obtain better mechanical properties, special size, surface gloss, and thinner thickness. The heat sink 12 is manufactured by cold rolling it to a thickness of 0.1 to 0.2 mm and then shirring it to a certain width. In the automated manufacturing process to improve productivity, a hot-rolled copper plate is cold-rolled and then a shirring process is performed. After the shirring process, the thermoelectric element (11) is cut to a certain standard. ) is automatically attached with thermal grease. The task of attaching special sponges can also be automated as needed.

The gaps 10a and 10b of the heat sink 12 attached to the thermoelectric element 11 are manufactured to be 1 mm or less. If the gap (between mountains) of the heat sink 12 is irregular or wide, high performance suitable for the intended use cannot be obtained and performance is significantly reduced, so it is manufactured with a gap of 1 mm or less. For example, the narrower the gap is to 0.1mm, the better the performance (more heat or cold can be obtained), so it can be applied to the development of more high-performance devices. However, it is not good for the gap to be infinitely narrow, so it must be manufactured in a way that maximizes the performance of the cooling module according to the intended use of the device. In addition, the width from mountain to mountain is less than 15mm and is manufactured to suit the purpose. If this is too large, only the size of the heat sink 12 will be large and the performance of the cooling module will be reduced, so the width is manufactured to be 15 mm or less in proportion to the performance of the thermoelectric element 11.

Looking at the three-dimensional view of the cooling module, it is manufactured by adhering parallel heat plates 12 to the upper and lower surfaces centered on the thermoelectric element 11. The cooling module made of the thermoelectric element 11 and the heat sink 12 is viewed from the front (front view). It is penetrated because there is a gap between the thin copper plates, and when viewed from the side (side view), it appears to be blocked by the rolled copper plates.

Figure 7 is a diagram showing the structure of a mattress according to an embodiment of the present invention.

Referring to FIG. 7, the coolant circulating cold mat includes a surface layer 101 forming the upper plate, a flat ice pack layer 102 that maintains coolness by absorbing cold air from the coolant circulating along the high pressure hose, and a flat ice pack layer 102. ) It is composed of a cooling water circulation layer 103 for delivering cold air to the area and making it last for a long time, and a bottom layer 104 forming the bottom. When these are stacked and sewn along the edge, a single cold mat 100 is produced. do.

The surface layer 101 is the top layer of the mattress and is manufactured by adding a waterproof coating or desired material to fibrous fabric.

The flat ice pack layer 102 is shaped like a thin pad and is manufactured according to the purpose by inserting a cold special material like an ice pack inside PVC or waterproof fabric and using a high-frequency fusion method. A fibrous mesh (mesh 102b) that absorbs the injected material is inserted into the ice pack (102a) to ensure that the ice pack (102a) maintains a flat surface even when a cold special material is injected, and several ice packs are installed depending on the area. (102a) is attached to the coolant circulation layer (103) using an adhesive suitable for the purpose.

The cooling water circulation layer 103 is formed by creating high-pressure hose buried grooves 103a at regular intervals and in a shape that can bury the high-pressure hose 13 in an insulating material such as a bridge or a special sponge, and then burying the high-pressure hose 13 thereon. Produce. The reason for using an insulating material or a special sponge is to completely seal it to prevent condensation by blocking it from the outside air because there is a risk of water forming due to condensation on the surface of the high pressure hose when cold coolant below zero flows inside the high pressure hose. .

The bottom layer 104 is made of various fabrics such as waterproof, water-repellent fabric, or non-woven fabric, and can be manufactured in various forms such as dots or embossing to prevent slipping on the bottom surface.

Figure 8 is a diagram showing a cross-section of a cooling water circulation layer of a mat and a flat ice pack according to an embodiment of the present invention.

Referring to FIG. 8, the coolant circulation layer 103 is manufactured by burying high-pressure hoses 13 at regular intervals on a bridge or special sponge and attaching a plurality of ice packs 102a thereon with adhesive, forming an antifreeze circulation mattress. Depending on the size of 100, only one sheet can be attached, or the ice pack 102a can be manufactured in various sizes, so it can be manufactured by attaching multiple ice packs 102a.

Referring to the cross-sectional view, the ice pack (102a) is a ready-made product with a super-absorbent resin added to fabric such as nylon or non-woven fabric, or is manufactured to suit the purpose and performance. The inside absorbs the injected ice gel and is flat rather than inflated like a balloon even when opened widely. A fibrous mesh 102b is built in to maintain the unfolded state.

FIG. 9 is a diagram supplementary to FIG. 8.

Referring to FIG. 9, grooves 103a for burying the high-pressure hose 20 for circulating coolant are separately formed at regular intervals and shapes by fusion using a high frequency or electric heater on a bridge or a special sponge in which the high-pressure hose 20 is to be buried. It is manufactured by embedding the high-pressure hose 13 in the groove 103a and then firmly attaching the thin flat ice pack 102a with adhesive. The formed groove 103a is not formed so as to completely make a hole so that the high-pressure hose 20 to be embedded can fall downward, but can be used to bury the high-pressure hose 20 by pressing the fabric (cross-linking or special sponge as a raw material) with a high frequency or electric heater. Make sure that only grooves that are possible are formed.

Figure 10 is a diagram illustrating a plate having a passage through which coolant flows instead of a high-pressure hose according to an embodiment of the present invention.

Referring to FIG. 10, instead of the high pressure hose 20, it is manufactured by adhering to urethane vinyl 20-1 using a high-frequency fusion method to form a checkerboard-shaped coolant circulation passage 20-1a so that the coolant circulates. When high-frequency fusion (20-1b) is performed on urethane vinyl in a checkerboard shape, a passage (20-1a) through which coolant can flow is formed between the fusion portions (20-1b).

In addition to urethane vinyl, a type of vinyl suitable for the purpose is used, and the adhesive method is also glued in a way that suits the material. The high-pressure hose (20) connected to the cooling member is firmly bonded by being placed between two layers of urethane vinyl during high-frequency fusion.
