Heat exchanger and heat pump cycle provided with the same

A heat exchanger includes a refrigerant tube through which a refrigerant for absorbing heat from air flows, and a defrosting medium tube through which a coolant for supplying heat for defrosting flows. Two fins disposed on both sides of the refrigerant tube include a protrusion protruding toward an upstream side of the flow of air with respect to the refrigerant tube. The protrusion is provided with a clearance that allows melt water generated in the defrosting to flow on the upstream side of the refrigerant tube. The refrigerant tubes and the defrosting medium tubes can be alternately arranged in the upstream line. The protrusion protrudes such that the air can be introduced into an air passage from the side portion of the protrusion even when an end facing the upstream side of the flow of the air is closed with the core of frost.

Heat sink device for electronic cabinet - uses counterflow heat exchanger with vertical flow channels for cooling air stream and ambient air.

The heat sink device has a flat rectangular housing (1) for attaching to one sidewall of the electronic cabinet to an inlet opening (4) receiving the heated cooling air stream ejected from the cabinet and an exit opening (5) for feeding the cooling air back to the cabinet. A second inlet opening (6) is provided for cooled ambient air supplied to a counter-flow heat exchanger (8) with vertical flow channels (9) for the ambient air, which is subsequently discharged to the atmosphere via a second exit opening (7). The heat exchanger (8) comprises a packet of identical parallel profiles with a double T cross-section, together defining flow channels (9) with a rectangular cross-section, with curved deflectors (21a,21b) at the opposite ends of the heat exchanger (8) leading to the respective exit openings (5,7). USE - Compact electronic cabinet coping with high heat losses.

Heat exchanger for treating or cooling - installation

Enclosed aluminium bodies consisting of shaped plates are connected to an element extending over their entire length. This element connects the bodies to the perimeter of a pipe, through which a heated or cooling liquid flows. These devices form a central passage opening for the pipe in the element.

Convector radiator with steel tube manifolds - has coupling sleeve joining oppositely threaded manifold ends

Two parallel manifolds are joined together by a series of vertical finned tubes. Each manifold is of steel tube, having portions at each end reducing in diameter in two successive steps (12, 13). The larger of these two portions, nearest the main part of the manifold (7), has a thread of opposite pitch to the corresponding portion at the other end of the manifold, and accommodates an internally tapped sleeve (16) with two threaded sections of opposite pitch. The smaller end portion (13) whose diameter is less than that measured between the bases of the threads in the larger portion (12) provides a sealing butt joint for piping, the manifold of another radiator, or a closing plug.

AIR CONDITIONING DEVICE FOR PREVENTING, AT LOW EXTERNAL TEMPERATURE, THE APPEARANCE OF FROZEN ON HEAT PUMPS, AND FOR IMPROVING THEIR OPERATION AT HIGH EXTERNAL TEMPERATURE

Le dispositif permet une diffusion homogène d'air chaud et d'air froid pour les PACS air/air et air/eau Diffuseur (1)(2)(3)(4)(5)(6) à taille modulable harmonisant la diffusion d'air vers les PACS air/air et air/eau en optimisant la diffusion d'air chaud ou froid grâce aux calories provenant d'un extracteur d'air (8) ou la VMC de l'habitation mais aussi les puits canadien, éoliennes, caves.... Ceci grâce à trois alimentations d'aspiration (9)(10)(11)(12)(13), chacune passant par la batterie de chauffage (7) garant d'une température positive en cas de grand froid. Deux trappes latérales (5) facilitent toutes interventions techniques. Un joint en caoutchouc entre le diffuseur et la PAC sécurise le transfert d'air entre les deux appareils. Un éventail (6) à la base du diffuseur permet d'orienter l'air chaud. Le diffuseur dispose de deux types de tubulures (3)(4) véhiculant l'air. Le diffuseur est destiné à optimiser le rendement des PACS air/air air/eau. The device allows homogeneous diffusion of hot air and cold air for PACS air / air and air / water Diffuser (1) (2) (3) (4) (5) (6) with adjustable size harmonizing the diffusion from air to air / air and air / water PACS by optimizing the diffusion of hot or cold air thanks to the calories coming from an air extractor (8) or the VMC of the house but also the Canadian wells, wind turbines, cellars .... This thanks to three suction power supplies (9) (10) (11) (12) (13), each passing through the heating battery (7) ensuring a positive temperature in case of extreme cold. Two side hatches (5) facilitate all technical interventions. A rubber seal between the diffuser and the PAC secures the air transfer between the two devices. A fan (6) at the base of the diffuser allows to direct the hot air. The diffuser has two types of tubing (3) (4) conveying the air. The diffuser is designed to optimize the performance of PACS air / air air / water.
