Definitions

  • the present invention relates to a cooling device wherein the board casing is prevented from being deformed.
  • cooling devices especially in refrigerators and freezers, polyurethane-based insulation material is usually filled between the inner wall and the outer wall of the body in order to provide thermal insulation between the inner volume of the body and the external environment.
  • the cooling device also comprises a door to close and seal the body which is the storage volume.
  • the cooling device may be formed as a growth chamber, an ice box, a refrigerator, a freezer, a refrigerator-freezer combination and/or a wine cooler.
  • the inner wall and the outer wall of the body are placed in a mold and an insulation material such as polyurethane is injected between the inner wall and the outer wall in liquid form while inside the mold, and then the polyurethane expands after a while due to its properties, filling the insulation volume between the inner wall and the outer wall. Due to the method used to fill the insulation volume with insulation material, the insulation material does not spread homogeneously inside the insulation volume. In particular, if the body is removed from the mold without waiting for the curing and cooling of the insulation material, the insulation material continues to cool down.
  • an insulation material such as polyurethane
  • the board casing which is located in the cooling device as embedded in the insulation volume and which protects the circuit board, is also deformed during the polyurethane injection process due to the reasons mentioned above.
  • said structural defects which occur in the board casing due to the polyurethane injection process are solved by placing various support members between the board casing walls. This process both increases the cost and requires additional labor.
  • a cooling device wherein the deformation of the casing during the polyurethane process is prevented by means of a protrusion provided on the board casing.
  • the protrusion is a protrusion which passes through the circuit board placed into the casing.
  • the aim of the present invention is the realization of a cooling device comprising a board casing of which the strength is increased against the pressure exerted by the insulation material during the application of the insulation material.
  • the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body having an inner wall and an outer wall and an insulation volume remaining therebetween; a board casing which is disposed in the insulation volume; and at least one protrusion which increases the strength of the board casing during the application of the insulation material into the insulation volume and which is broken afterwards to be removed from inside the board casing.
  • This temporary arrangement of the protrusions eliminates the need to make any design changes to the board casing or the boards to be placed into the board casing.
  • the board casing is preferably a casing which receives circuit boards, or can be a casing which receives other physical components.
  • the protrusion extends from the base of the board casing to the ceiling of the board casing in the vertical axis.
  • the protrusion comprises at least one recess which is arranged thereon, which allows the protrusion to be broken and removed from inside the board casing after the application of the insulation material is completed, which extends parallel to the base along the protrusion, which weakens the protrusion and which causes the notch effect.
  • the recess extends continuously parallel to the base.
  • the recess extends along the protrusion, parallel to the base, intermittently, at intervals.
  • the recess is arranged on the protrusion, at the bottom of the protrusion, that is, closest to the base of the board casing.
  • the cross-section of the recess is triangular or circular. Thus, it is ensured that the protrusion is broken smoothly along a certain cross-section. In addition, it is ensured that the remaining part does not harm the operator.
  • the protrusions extending from the base of the board casing thanks to the protrusions extending from the base of the board casing, during the application of the insulation material, the strength of the board casing is increased and it has been ensured that the walls of the board casing are prevented from being deformed, and moreover, after the application of the insulation material is completed, the protrusions are broken and removed from inside the board casing such that the desired circuit board is easily placed into the board casing, regardless of the dimensions of the circuit board to be placed in the board casing.
  • Figure 1 - is the sideways cross-sectional view of a body and the board casing therein.
  • the cooling device comprises a body (1) having an inner wall and an outer wall and an insulation volume remaining therebetween; a board casing (2) which is disposed in the insulation volume; and at least one protrusion (5) which increases the strength of the board casing (2) during the filling of the insulation material into the insulation volume and which is broken afterwards to be removed from inside the board casing (2).
  • the deformation of the walls of the board casing (2) is prevented during the production of the cooling device and the filling of the insulation material, and after the application of the insulation material is completed, the protrusion (5) is broken by the operator and removed from inside the board casing (2) such that the circuit board can be easily mounted into the board casing (2) without any limitations arising due to the protrusion (5).
  • the protrusion (5) extends from the base (3) of the board casing (2) to the ceiling (4) of the board casing (2) in the vertical axis.
  • the protrusion (5) comprises at least one recess (6) which is arranged thereon, which allows the protrusion (5) to be broken and removed from inside the board casing (2) after the filling of the insulation material is completed, which extends parallel to the base (3) along the protrusion (5) and which weakens the protrusion (5).
  • a break line (F) is formed, thus enabling the operator to break the protrusion (5) easily and quickly.
  • the recess (6) extends on the protrusion (5) continuously parallel to the base (3).
  • the recess (6) extends on the protrusion (5), parallel to the base (3), intermittently, at intervals.
  • the recess (6) is arranged on the protrusion (5), at the bottom of the protrusion (5), that is, closest to the base (3) of the board casing (2).
  • the cross-section of the recess (6) is triangular.
  • the cross-section of the recess (6) is curved, preferably semicircular.
  • the protrusions (5) extend from the base of the board casing (2) towards the ceiling (4) thereof. During the application of the insulation material, said protrusions (5) support the walls of the board casing (2) and increase the strength of the board casing (2) during the application of the insulation material. After the insulation material is filled, the protrusions (5) are preferably broken from the bottom, that is, closest to the base (3) of the board casing (2), and removed from inside the board casing (2) as the operator applies a force to the opposite direction of the side where the recesses (6) are arranged. In this case, only the part of the protrusion (5) up to the recess (6) remains at the base (3) of the board casing (2), which does not prevent the placement of the circuit board to be placed in the board casing (2). Afterwards, the circuit board is placed in the board casing (2) by the operator and the assembly process is completed.
  • the protrusions (5) extending from the base (3) of the board casing(2), during the filling of the insulation material, the strength of the board casing (2) is increased and it has been ensured that the walls of the board casing (2) are prevented from being deformed, and moreover, after the filling of the insulation material is completed, the protrusions (5) are broken and removed from inside the board casing (2) such that the desired circuit board is easily placed into the board casing (2), regardless of the dimensions of the circuit board to be placed in the board casing (2).
