Definitions

  • the invention relates to a cold storage element which contains a eutectic brine set for cold storage to a certain freezing point, in which one or more pipelines carrying a refrigerant for freezing the brine run and which is arranged in the structure of a refrigerated vehicle, and a holder for such cold storage elements and air control slats.
  • cold storage elements filled with a brine suitable for cold storage in plate form or in the form of round metal pipes.
  • a disadvantage of these known shapes and designs of cold storage elements is that the cold-emitting or heat-absorbing surface of the elements is only limited and, in the case of single-row attachment, corresponds to a maximum of 1.6 times the base area of the vehicle body.
  • a further disadvantage is that elements in plate form may only be short to absorb the static pressure when braking or starting the vehicle and that when metal pipes running lengthwise through the body are filled with a gelling cold storage agent, the poorer thermal engineering Has properties.
  • the cold storage elements according to the invention should continue to be able to be filled with normal eutectic brine, they should be able to extend over the entire length of the vehicle body and there should also be the possibility of being able to defrost the surface even when loaded.
  • This object is achieved in the above-mentioned cold storage element in that it consists of a plastic jacket, which has a rectangular shape and in the middle has a longitudinal web connecting the two side walls and the pipeline of the refrigerant in the form of a hairpin both by the upper and lower formed by the longitudinal web Chamber runs.
  • Static pressure exerted when the vehicle brakes and accelerates is advantageously provided with crossbars for further subdivision within the two chambers, which have at least one opening of small size for filling the elements with brine, without short-term mass transport through the bore.
  • Simple non-return flaps can advantageously be arranged in the openings, which prevent the brine from shifting during braking.
  • a gutter for collecting the defrost water is preferably arranged below each rectangular shell, the opening of which points upwards and the width of which exceeds the width of the shell, with one inside each gutter for faster defrosting of the elements Pipe for passing heating fluid or an electric heating element can be arranged.
  • the plastic jacket of the elements is advantageously transparent and thus allows the state of freezing of the brine to be checked and, furthermore, a release agent, such as silicone oil or the like, which delays ice formation and facilitates ice solution, can advantageously be applied to the surface of the jacket.
  • a release agent such as silicone oil or the like, which delays ice formation and facilitates ice solution
  • the plastic surface can advantageously also have a separating or wax-like surface (PTFE, PE).
  • the vehicle body for attaching the cold storage elements advantageously has cross members for holding the elements, which can be arranged at regular intervals from one another and in or below the gap between adjacent elements can be an adjustable or thermostat extending over the element length Controlled slat can be arranged, the width of which corresponds approximately to the gap width and which can be mounted centrally to compensate for the forces acting on it.
  • conventional cold storage elements consist of plates or tubes filled with gelled brine.
  • a lower chamber 6 for the eutectic brine is formed.
  • a tube 4 for the refrigerant runs like a hairpin, which brings the brine to the desired low temperature and freezes it.
  • the elements are made of plastic, namely polyethylene and their surface is coated with a release agent, e.g. B. Silicone oil, provided. Because of this release agent, the depositing of ice is either prevented or the ice cannot form a firm connection with the plastic surface, so that it falls off automatically due to the movement of the vehicle while driving.
  • a release agent e.g. B. Silicone oil
  • V - shaped channels 9 can be arranged below the elements, in which heating rods 10 run and whose opening width of the opening pointing upwards is greater than the width of the cold storage elements.
  • the draining water is collected in the channels and drained so that diving is possible even when the vehicle body is loaded or the cold storage elements can also be used in the plus range, since condensed water is also drained off via the channels 9 and that too cooling goods can not affect.
  • the cold storage elements are mounted on cross members 11 which are fixedly arranged in the vehicle body and which can be at a considerable distance from one another, since the elements bear better due to the favorable cross-sectional design. In the case of shorter and smaller vehicles, it is sufficient if the crossbeams are on the front and rear walls of the body and this enables optimal use of the cooled space.
  • the cold storage elements are at a distance from one another which corresponds approximately to their width and in the gap or below the gap between two adjacent elements there is a lamella 12 which is mounted in the center and which, because of its setting, passes through those between the elements Airflow regulates.
  • the fins 12 can be set automatically, mechanically via a temperature bellows without additional auxiliary energy, but they can also be set by an electric motor be adjustable by thermostat.
  • the cold storage elements according to the invention it is possible for the first time in the cold storage elements according to the invention to use long rectangular sheaths or tubes made of plastic without the filled eutectic brine having to be gelled, as a result of which the cold storage capacity would be reduced.
  • the static pressure in particular when the vehicle is braked sharply, is absorbed by the longitudinal web 2 and the transverse webs 7, the filling of the elements being made possible by the bores 8, but on the other hand a movement of the refrigerant is suppressed to such an extent that the use of rectangular Plastic jackets is possible.
