Heat insulator

Abstract

Disclosed is a refrigerator. The refrigerator includes a main body including a vacuum adiabatic body. The refrigerator includes a suction pipe heat exchanger. The suction pipe heat exchanger includes a heat exchange pipe for exchanging heat between a suction pipe and a capillary pipe to improve cycle performance. The suction pipe heat exchanger comprises: a first withdrawal portion which is withdrawn from one side of the heat exchange pipe to a first space formed inside the main body; and a second withdrawal portion which is withdrawn from the other side of the heat exchange pipe to a machine room. A block forms a portion of the main body. The block is formed of a non-vacuum adiabatic body such as polyurethane foam. The suction pipe heat exchanger is embedded and installed in the block. Accordingly, as a plurality of withdrawal holes are formed in one side of the block and the other side of the block, a vacuum adiabatic panel does not need to include a penetration portion for penetrating the first withdrawal portion and the second withdrawal portion of the suction pipe heat exchanger, and damage to the vacuum adiabatic panel due to thermal changes in the suction pipe heat exchanger may be prevented.

Description

[Technical Field]

[0001] The present disclosure relates to a heat insulator. The present disclosure relates to a refrigerator including a heat insulator.[Background Art]

[0002] In general, in a refrigerator, a cycle pipe through which a refrigerant flows undergoes a temperature change of -40 to 40°C depending on an on / off operation of a cycle, and when a penetration component is applied to a vacuum adiabatic refrigerator, a penetration portion is formed through a vacuum adiabatic panel.

[0003] As a result, when thermal stress is applied to the vacuum adiabatic panel, a sealing portion or welded portion of the vacuum adiabatic panel is damaged or deformed, causing problems of decreased reliability such as vacuum leakage, etc.

[0004] Korean Patent Registration No. 10-2543420 (issued on June 14, 2023) related to a vacuum leakage problem of a vacuum adiabatic panel discloses a vacuum adiabatic body and a refrigerator. The patent document discloses a heat exchange conduit that connects two conduits, which are an inlet pipe of an evaporator and an outlet pipe of the evaporator, to improve cycle performance of a vacuum adiabatic refrigerator.

[0005] According to the patent document, the heat exchange conduit includes a minimum of penetration holes that penetrate the vacuum adiabatic panel.

[0006] However, the patent document includes manufacturing difficulties because the penetration holes are formed in the vacuum adiabatic panel to allow the penetration component to penetrate, and airtight welding, etc., should be performed.

[0007] Further, the patent document does not present an alternative regarding a structure in which the heat exchange conduit bypasses the vacuum adiabatic panel without penetrating the vacuum adiabatic panel.[Disclosure][Technical Problem]

[0032] According to embodiments of the present disclosure, the following effects can be achieved.

[0033] First, a storage chamber is provided in a main body. An evaporator is disposed in the storage chamber. A machine room is disposed on one surface of the main body to be partitioned from the storage chamber. A block is disposed between the main body and the machine room. The block partitions the storage chamber and the machine room of the main body. The block is a non-vacuum adiabatic body. The block can be molded by foaming a polyurethane foaming liquid filled inside the block cover. A penetration component is provided inside the block. The penetration component exchanges heat between a suction pipe and a capillary pipe to improve cycle performance.

[0034] Second, the penetration component includes a pipe embedded and installed inside the block. The pipe may be formed in a zigzag shape. A pipe receiving part may be formed inside the block. A first withdrawal hole may be formed to penetrate one side of the block so that a first withdrawal portion withdrawn to the storage chamber from one side of the pipe penetrates. A second withdrawal hole may be formed to penetrate the other side of the block so that a second withdrawal portion withdrawn to the machine room from the other side of the pipe penetrates.

[0035] Through this, the penetration component is embedded and installed in the non-vacuum adiabatic body such as polyurethane foam, etc., so there is no need to form the penetration component in a vacuum adiabatic panel for the penetration component to be disposed inside the vacuum adiabatic panel. A refrigeration cycle apparatus and the vacuum adiabatic panel can be separated and independently manufactured and / or assembled.

[0036] In addition, even if thermal stress is applied to the block due to thermal changes of the pipe according to cycle on / off, the block can be prevented from being damaged.

[0037] Third, the penetration component is separated from the vacuum adiabatic panel, so there is no concern about interference between a supporter provided inside the vacuum adiabatic panel and the penetration component. Through this, the insulation performance of the vacuum adiabatic panel can be maintained.

[0038] Fourth, the first withdrawal portion and the second withdrawal portion of the penetration component are disposed to be spaced apart from each other. Through this, heat exchange and / or heat leakage between the first outlet and the second outlet can be minimized.

[0039] Fifth, the pipe is formed in a zigzag shape in one direction. The capillary pipe is sealed or welded to be connected to one side and the other side of the capillary pipe in the one direction and the other one direction different from the one direction with the pipe interposed therebetween, so that bending work of the pipe can be performed smoothly.[Description of Drawings]

[0116] The first pipe is configured to transfer a refrigerant expanded by the expander 115 (capillary pipes 1151 and 1152) to the evaporator 133. The second pipe is configured to transfer the refrigerant evaporated by the evaporator 133 to the compressor 113.

[0117] A penetration component 122 may be provided in a portion of the second pipe. The penetration component 122 is a refrigerant pipe connected between the evaporator 133 and the compressor 113, and sucks the refrigerant passing through the evaporator 133 into the compressor 113. The penetration component 122 (Suction Line Heat Exchanger; SLHX) may be configured by sealing or welding the capillary pipes 1151 and 1152 to an outer circumferential surface of the penetration component 122 by soldering or the like. The penetration component 122 is configured to connect surfaces of the capillary pipes 1151 and 1152 and the penetration component 122 to each other on an upstream side of the compressor 113 to perform heat exchange.

[0118] The penetration component 122 includes a pipe 123, a first withdrawal portion 126, and / or a second withdrawal portion 127. The pipe 123 may comprise a plurality of straight pipes 124 and a plurality of curved pipes 125.

[0119] The straight pipe 124 may extend in a first direction. The plurality of straight pipes 124 are disposed to be spaced apart from each other in a second direction different from the first direction. Here, an example of the first direction may mean an X-axis direction. An example of the second direction means a Y-axis direction. The plurality of straight pipes 124 include a first straight pipe 1241 to an Nth straight pipe. Here, N is a natural number of 2 or greater.

[0120] The curved pipe 125 may extend in the second direction. The curved pipe 125 is disposed between two straight pipes 124 adjacent in the second direction.

[0124] An arrangement direction of the first capillary pipe 1151 and the second capillary pipe 1152 may cross a spacing direction of the plurality of straight pipes 124 or a bending direction of the plurality of curved pipes 125. Accordingly, it is easy to bend the plurality of capillary pipes 1151 and 1152 after sealing to the penetration component 122 or after line welding.

[0125] If the capillary pipes 1151 and 1152 and the curved pipe 125 are bent separately and then sealed or welded, an interconnection and / or welding position (or sealing position) of the two pipes may vary due to machining tolerances of the two pipes during bending. Therefore, in order to resolve machining tolerance and / or welding mismatch (or sealing mismatch) problems of the capillary pipes 1151 and 1152 and the pipe 123, it is preferable to seal or weld the two capillary pipes 1151, 1152 and the pipe 123 in a straight form and then bend the sealed or welded pipes.

[0126] The first straight pipe 1241 to the Nth straight pipe may be disposed to be spaced apart from each other sequentially from one side to the other side in the second direction.

[0155] The plurality of straight pipes 124 may be disposed spaced apart at a predetermined interval in the X-axis direction. The first withdrawal portion 126 and the second withdrawal portion 127 are disposed spaced apart in the X-axis direction. A distance between the first withdrawal portion 126 and the second withdrawal portion 127 may be smaller or larger than a distance between the plurality of adjacent straight pipes 124.

In the embodiment, the distance between the pipe receptacle 128 and one surface of the third block portion 1054 may be larger than the distance between the pipe receiver 128 and the other surface of the third block portion 1054. Accordingly, the block 105 further spaces a position of the pipe receiver 128 that covers the pipe 123 toward the machine room 106 with respect to the second storage chamber 108, thereby relatively increasing an adiabatic thickness and efficiently securing adiabatic performance.

[0159] A movement path of the refrigerant will be described below.

A temperature of the refrigerant flowing along the capillary pipes 1151 and 1152 is higher than a temperature of the refrigerant flowing along the evaporator 133.

[0161] Here, the penetration component 122 transfers heat from the refrigerant flowing along the capillary pipes 1151 and 1152 to the refrigerant that has passed through the evaporator 133 and then delivers the heated refrigerant to the compressor 113. Accordingly, cycle performance may be improved.

The hot line is a refrigerant pipe connected to the condenser 114 and / or extending from the condenser 114, and is a component that dissipates heat received from the refrigerant that has passed through the condenser 114. The hot line may transfer heat to a second plate of a vacuum adiabatic body or a gasket of the doors 109 and 110, etc. Accordingly, a dew condensation phenomenon due to a temperature difference between the inside and the outside of the refrigerator may be minimized.

[0163] The cover 129 is installed along one surface of the main body 100. The hot line may be coupled to the cover 129. The cover 129 is configured to cover the hot line.
